General Information
To help you assemble your new Versa and mount it to your tractor, we provide you with
drawings, instructions and general information. When needed, you can get information or
clarification from Alamo Group Customer Service or from engineering departments over the phone.
This publication provides general information not specifically for your case or tractor, but, in
connection with the drawings, this publication offers you some valuable assistance - please read it
thoroughly.
These mount kits are made for selected tractors with standard configurations. Only the noted
options and tire sizes listed on the installation drawings will work with these mount kits. Other
options, front axles, or different tire sizes may prevent the mount kit from fitting your non - standard
tractor. Alamo Group cannot take responsibility for these problems or any modifications made to
the unit.
These instructions have been prepared to assist you in the correct procedure for mounting an
Alamo Group A-Boom on your tractor.
Throughout these instructions, references are made to right or left directions. Right and left
are determined by sitting on the tractor seat and facing the direction of travel.
This is the Safety-Alert symbol. When you see this symbol on your machine or in
these instructions, be alert to the potential for personal injury.
Follow recommended precautions for safe assembly and operating practices.
DANGER!
WARNING!
CAUTION!
A signal word - DANGER, WARNING, or CAUTION - is used with the
Safety Alert symbol identifies the most serious hazards.
Safety signs with signal word WARNING are typically used to point out
more serious hazards.
General precautions are listed on CAUTION safety sign. CAUTION also
calls attention to safety messages in these instructions.
NOTE: Included in the packing box of this unit is a replacement filter element for filter assembly in
the tank. This mower unit's hydraulic components have been carefully cleaned and packaged
at the factory to prevent contamination from entering the system. However, dust and dirt
particles may enter into the sealed components through transportation, handling, rain or just
sitting in a dirty or harsh environment. Therefore to assure that the hydraulic system is
properly clean please adhere to the following procedure.
1.
Prepare the area where the unit is to be assembled. The area should be on a hard concrete
floor that has been swept clean of all dust and contaminants. Un-package the mower unit
carefully so that the seals on the hydraulic components are not broken or pulled off. Lay out
parts to make location easy. Figure 1
2.
Inspect and clean all hydraulic hoses and fittings prior to installing them onto the tractor or
mower. If dirt or material is seen in any of the parts, they should be washed and cleaned
thoroughly with an oil-compatible solution. Do not blow the material further into a hose since
this sometimes does not remove the foreign material and can cause damage to hydraulic
components down stream.

General Information
IMPORTANT:
Change the return filter in tank and suction filters after the first 200 hours of
operation. Change the filters again at 700 hours; then, change the oil and filters at
1600 hours. After that, continue to change the filter every 800 hours and the oil
every 1600 hours. Hydraulic oil to be used is Universal Tractor Hydraulic . Use the
above procedures as part of a good filter maintenance program.
Between filter changes, monitor condition of filter by reading Pressure
Gauge mounted on filter on top of the Tank. If pressure reads 15 psi or greater at
1800 RPM engine speed and normal operating temperature (140 deg. F. or
greater), filter element should be changed. Pressure gauges are color-coded to
help indicate when to change element.
WARNING!
Escaping fluid under pressure can penetrate the skin causing serious
injury. Relieve pressure before unhooking hydraulic or other lines. Tighten all
connections before applying pressure. Keep hands and body away from pinholes
and nozzles which eject fluids under high pressure. Use a piece of cardboard to
search for leaks. If ANY fluid is injected into the skin, it must be surgically removed
within a few hours by a doctor familiar with this type injury or gangrene may result.
CAUTION!
To prevent personal injury, always wear SAFETY SHOES, SAFETY
GLASSES, and GLOVES. A HARD HAT should be worn by anyone working
under a Crane Hoist or
Block-and Tackle.
WARNING!
When working with or on the machine, take care and stay alert. Always be
careful. Always be alert for hazards. Watch out for others.
CAUTION!
ALWAYS USE GLOVES WHEN HANDLING THE BLADES! Before re
moving or installing blades, make sure that the head is leaned back past the
vertical position. If the head is not, the blades can come off suddenly when the
bolts are removed.
WARNING!
Block up or securely support components before working under or around
lifted components. Inadvertent falling can cause serious injury or death.
CAUTION!
The operator should not leave his seat with this valve engaged or
with the tractor engine running. Allow approximately 60 seconds for the
blades to come to rest after turning the switch off before dismounting.

Versa Frame Mounting Components.
Shown in Figure 1 are the parts needed to mount
the versa frame to the tractor. Follow instructions
listed below and reference back to figure 1 as
needed.
2.
Remove The factory Brackets. If there
are factory mounting bracket on each side of the
tractor which may be optional for mounting options on the tractor. They may have to be removed or they may not, check for any optional
brackets that came with the tractor. Removed
and not used. (See Figure 2)
Removed Tractor
Parts that will not be
used

3.
Install RH Versa Frame Mounting
Bracket. The bolt holes in the tractor frame will
be used to mount the versa frame mounting
brackets. The Mounting Bracket P/N
(LH
or RH ). The mounting brackets has an angle to
them, make certain that they are mounted correctly. The RH Side of the Tractor is shown in
Figure 2 & 3. The holes in the frame shows the
two holes used to align the bracket (See Figure
3). When mounted the plate should slope to the
rear (See Figure 4) on the RH side of tractor.
Slide the bracket over the two bolts and start the
nuts. The bolts will have to be put into the holes
from the back side, this can be done by opening
the engine access door right above the holes.
Install the rest of the bolts and lockwashers on
the bolt and tighten them.
Figure 3
RH Side of Tractor
4.
Install LH Versa Frame Mounting
Bracket. The LH frame mounting bracket will
mount the same as the RH does (See Figure 5).
The Bracket will angle toward the rear of the
tractor and have a total of six bolt, lockwashers
and nuts. Tighten these six (12 counting RH & LH
Side) now to the required torque (See Bolt
Torque Chart in Specifications Section). These
12 bolts will not need to be removed later so they
can be tightened.

Section 4 - 3
Versa Frame Installation
5.
Install Versa Mounting Plate to Mounting Brackets. The mounting Plates (LH & RH side)
will bolt to the mounting brackets using the six bolts on each side (use only 2 during the fitting
process and it is best not to use locknuts). Bolt these plates to the outside of the mounting
brackets on the RH side and to the inside on the LH side, (this is important for mounting after
welding). Install 2 bolts and nuts (See Figure 8), snug them only as you will be removing them to
weld frame after it is fitted (See Figure 6 & 7).
6.
Check The Frame Mount Brackets & Frame Nounting Plates. It is very IMPORTANT
that the frame mounting plates are bolted to the Frame mounting brackets correctly. Double
check this now to be certain theyare. See figure 8 to make certain the RH side has mounting plate
on the outside of mounting bracket, the LH side mounting plate is bolted to the inside of the frame
mounting bracket.
7.
Test Fit Versa Frame Under Tractor.
The versa frame is slid under tractor from the
Left hand side. Using floor jacks (or hoist) lift
frame up under mounting plate till it fits as far to
the front of plate as it will go (plate is curved
downward in front. Make certain to have 9”
distance from end of frame to the RH mounting
plate (See Figure 8), the 9” distance is critical
sa double check this before any welding. Once
again make certain that the RH Mounting Plate
is on the outside of frame bracket and the LH
mounting plate is on the inside of the frame
mounting bracke t (See Figure 8). This is important later after welding to ensure a fit..

Leveling The Versa Frame. First
Make certain the tractor itself is level, Make
certain the tractor tires are the correct sizes
and that they are aired to manufacturers recommendation. Keep in mind changing tires
LH
after mounting versa boom can change the
Side
level of the mower. The Versa Frame should
Shown
Tack
be lower in the front by approximately 1/8” than
Weld
in the back, this allows the mower to operate
Here
with the front of the mower a little lower than
Both
the rear. The versa frame must be out to the
Sides
RH side from mounting plate by 9” (9-1/4” Max)
As shown above (See Figure 8). Once the
Figure 9
measurements are correct check the versa
frame for level (See Figure 9). These level
checks can be done on the LH or the RH side using a bubble level (See Figure 9) if leveled
correctly, recheck all measurements (See Figure 6). Do Not Tack weld the mount plates to the
frame until all measurements and level has been checked, Make certain that the versa frame is
square with the tractor frame. Tack welded to the Versa Frame lightly to secure it so as not to
move. The Tack weld must be light enough that they can be broken loose if realignment is
needed. DO NOT unbolt Versa frame (Mount Plates) from Frame Mounting Brackets yet.

Aligning Versa Frame with Mounting
Brackets. The Versa Frame must be aligned
with the mounting frame to where it will extend
out past mounting plate 9” on the right hand
front side as shown in Figure 8 & 10. This
measurement is important and must be correct
in order for mower to operate correctly. The
Versa Frame should be lower in the front by
approximately 1/8” than in the back, this allows
the mower to operate with the front of the
mower a little lower than the rear. Once the
measurements are correct check the versa
frame for level again. These level checks can
be done on the LH side using a bubble level
(See Figure 8) if leveled correctly then tack
weld the versa frame to the mounting plate on
both sides of the tractor, the tack welds need to
be strong enough to hold the versa frame up.
Recheck all measurements (See Figure 6).
Make certain that the RH side (Shown) and the
LH side mount plate is tack welded to the Versa
Frame. The Tack weld must be sufficient
enough to support the versa frame to the
mounting plate when unbolted.

Pre-Fit Hydraulic Tank. Make certain that the Versa Frame has been tack welded to the
mounting plate on the LH & RH side of Versa Frame (See Figure 9, 10 & 11). The Hydraulic Tank
will need to be pre-fit to the Versa Frame. Using an over head hoist align the outside Tank Mounting
holes in tank with the holes in the Versa Frame. Snug the two bolts of tank for the two outer holes.
These holes are slotted so the tank can be moved forward or back to give Hydraulic tank and
tractor components (Fuel Tank) clearance (See Figure 11 & 12). When you have sufficient
clearance with the tractor components and
hydraulic tank install the inner two tank
mounting lugs to the Tank with the two bolts
supplied. The Tank Mounting lugs will sit on
the Versa Frame on the inside of the tank.
Tack weld the lugs to the versa frame. Remove the Tank from the versa frame and set
it aside for now (See Figure 11 & 14). The
Tank Mounting Lugs can be welded now or
wait until the versa frame is unbolted and
removed.

Install the Versa Frame Step. The
Versa Frame Step will be welded to the side of
the versa frame (See Figure 15). Align the step
to where it will not interfere with the tractor
components and is accessible for the operator.
Tack weld it to the versa frame, Some Models
will not use this step as the tractors factory
setep is retained and it is not needed. Even
though the step may be sent it may not be
needed.
14.
Remove and Weld Versa Frame.
The Versa frame will need to be unbolted and
Figure 14
removed. This will allow for welding the mounting plates, tank mount lugs, the step and the
axle stabilizer mounting bracket to the versa
frame. The welds need to welded securely to
the frame, weld both sides of the mounting
components (See Figure 16). Touch up the
paint around the welded areas while the versa Outer

The hydraulic tank will be shipped fully assembled with the return filter, suction tube and
fittings (See Figure 16). Using an over head hoist
lift the tank to the tractor, use caution not to hit the
tractor with the tank (See Figure 17). Lower the
tank down onto the versa frame with the tank out
away from the versa frame (See Figure 18) then
push the tank inward toward the tractor until the
inner mounting lugs align (See Figure 19). Install
the inner mounting bolts and the outer mounting
bolts into the tank, torque these mounting bolts to
specifications (See Figure 20).

Install Boom Frame w/ King Post. The
Boom frame will have the Kingpost welded to it
from the factory (See Figure 29, 30 & 31). The
boom Frame will slide into the versa frame and
be retained by two long pins that are inserted
from the front through the versa frame and the
boom frame (See Figure 28). There are two large
bolts that will be inserted into the upright of the
boom frame and the upright of the versa frame
(See Figure 27) , these are located near the top
on the RH side. One bolt in front and one in back.
19.
Connect Boom to Boom Frame King
Post. The boom will connect to the king post. You
will need an overhead hoist for this (See Figure
27). Remove the Boom pivot pin from boom.
Lower boom down over turning arm that is on top
of the king post, align and reinstall pivot pin.
Tighten the pivot pin retaining bolt. Using the hoist
lower the boom down to the ground. The Boom
will have the Cylinder hoses (except Swing & lift
Cylinders) run through the boom (See Figure 28).
The Motor Pressure and Return lines (Steel
Tubes) are on the front side of boom, These lines
will connect to the hoses from the cutter motor
control valve block mounted on front of the boom
frame front bottom RH side (See Figure 26, 29,

Install Upper Rear Axle Brace . The upper rear axle brace will consist of a plate with
holes that will bolt to the lower rear axle brace on the RH rear axle. This plate will protrude to the
front of the axle. There will be a piece of rectangular tubing with two holes in one end. The are L
shaped brackets that will bolt to the tubing (on the boom frame end. These L shaped brackets
should be bolted to the tube and the tube slid in on top of the plate with holes at the rear axle, tube
should lay flat on plate. Tack weld the L brackets to the boom frame where they met the frame. Go
to the rear axle and tack weld the rectangular tube to the axle plate. Once the tube, Plate and L
shaped brackets ate tacked and straight they can be welded completely. (See Figure 26 & 28).
The Axle Brace should already be bolted to the rear axle of tractor. The “L’ Shaped brackets must
be welded securely to the versa frame (lower Brace) and the boom frame (upper brace).

Cutter Valve . The cutter valve is
mounted on the versa boom frame and
should be already bolted on to it when it is
shipped to you. If it is not then you will need to
bolted it on. The mounting plates for the valve
is attached to the versa boom frame on the
RH side and to the front, the valves will bolt on
to it but the valv emust be bolted on so the
correct ports are facing the correct direction
(See Figure 30) note that the releif is opointing
toward the front of the tractor and the pressure line from the pump is right above that
(See Figure25, 27, 32, 33, 34).

Connect the Motor Hoses to the
Cutter Valve. The Motor has two hose connected to it. It is important to ID which hose is
which through the sleeving as these hose
must correctly be attach to the cutter valve
and to the boom (See Figure 33, 34 & 35).
The ports on the cutter motor control valve
are marked, the pressure port to motor will be
marked M1, the return port from the motor will
be marked M2. The two steel tubes on the
boom are not marked, but they have two different ends on the steel tubes, the tube with
the square 90° turn is the pressure tube (M1).
The tube with the 90° bend in the tube itself is
the return line (M2) (See Figure 35). If these
hoses are connected backwards the only
thing that will happen is the motor will turn in
the wrong direction causing the blade to cut in
the wrong direction. Make certain these
hoses are in the sleeving material and the
fitting are securely tightened at both ends.

Tank Hose Installation:
1.
Check Hose Connection from Pump to Cylinder Control Valve. This will be the small hose
connection on the RH side of the pump (See Figure 44) for this hose, this hose cannot
be connected to Cyl. Control valve untill later.
2.
Check Hose Connection from Cutter Valve to Motor. The Hose from the Cutter / Motor
Control Valve runs down the Boom using Steel lines and Hoses (See Figure 44)
3.
Check Hose Connection Return Hose from Motor to Cutter / Motor Control Valve. Connect
the hose from the Motor return to the Cutter / Motor Control Valve (See Figure 44).
4.
Check Return Hose from Cutter Valve to Tank. Connect the return hose from the Cutter
/ Motor Control valve to the Tank. (See Figure 40). This hose will run down under tractor
to the left side. (See Figure 44, 45,46& 47) anfd then back up the LH side to the Tank.
(See Figure 47). The return hose connects to the return Filter Housing (See Figure 20).
5.
Check Return Pressure Gauge. The Return Pressure Gauge is a low Pressure Guage
that displays uses in Green and Red Fields, Return should stay in the Green when Oil is
warm and Tractor is running. Gauge may read in the red when oil is cold and engine RPM
is run to high, RPM should be keep low untill the oil warms up. (See Figure 47).

Access to Crankshaft Pulley. The Factory
Crankshaft Pulley will not need to be removed. The
Pulley Adapter will be bolted to the Factory Crankshaft Pulley.
3.
Install Pulley Adapter. The Pulley adapter
to be used is a round plate with 4 threaded
holes and four non-threaded holes in it. Notice
this pulley adapter will not have a center hole in
it (See Figure 4). The Non-treaded holes are
used to mount the Adapter to the Pulley using
bolts # 02979791 (10mm 1.5 P X 35mm
Gr.10.9) & Lockwasher # 00755954 (10 mm).
Do not use longer bolts to mount Pulley Adapter
to Pulley than is supplied with mounting kit.
4.
Driveshaft Assembly. The drive shaft is a
two piece Assembly, an inner and outer shaft
assembly (See Figure 5). The Shaft End has a
four bolt flange yokes on it that connect to the
Crankshaft Pulley Adapter. The Tube end has a
splined clamp yoke on it that connects to the
Pump. This Drive Shaft connects to the Pulley
Adapter. Note that the Universals of the Driveshaft
are in time. When installed in tractor they should be
in time as shown, both Yokes the same.

Install Shaft End of Driveline / Engine end. Install the Shaft 1/2 Assembly w/ Flanged Yoke into the
Engine compartment of Tractor, install it from the LH front Side down and under radiator. (See Figure
6). This needs to be installed this way because the Flange Yoke will not go through the Crankshaft access
hole in the front of the Tractor (See Figure 3). Bolt the Flange Yoke to the Pulley Adapter using the four
7/16" X 1-1/4" Bolts (Part # 02976344), use the four Lock Washers (Part # 00022200), put Locktite on
the threads of the Bolts and install them into Pulley Adapter. To Tighten these four Bolts, use a long
extension and go through the front Crankshaft Pulley access hole in front of Tractor. Do Not use bolts
longer than 1-1/4" long, longer bolts will damage Crankshaft Pulley.
Installing Pump Mount Plate & Tube End of Driveshaft:
1.
Install Pump Mount Plate. Install Front Pump Plate # 02976087 standard mount plate (See
Figure 7) or # 02979080 optional Pump Mount Plate w/ Pump Guard built on. (Not Shown) use the
2 Spacers on the JD 6615 Series, Do not install Pump Mount Plate without using these Spacers. The
Spacers are for Tractor Hood Clearance. Insert the 4 bolts and lock washers into Pump Mount Plate and
spacers (See Figure 7), tighten them to required Torque (See Bolt Torque Chart).

Driveline timing means the universal joints
are both the same position when driveline half is slid
together. If they are not timed, it will decrease the life
of the universal joint and in some cases could cause
a vibration. (See Figure 5 on previous page)
3.
Install Tube End of Driveline / Pump End.
Slide the Tube half of driveshaft through Pump
Mount Plate and Tractor Crankshaft Access Hole
(See Figure 8). You will have to align the Universals
when doing this (time the Driveshaft). Slide the two
together where the Universal are in time (See
Figure 5 on previous page), this will help the
driveshaft to operate smoothly.

Loosen Splined Clamp Yoke Retaining Bolts.
Insert a bar through the Yoke to hold Driveshaft up
and to help loosen the Bolts in the clamp Yoke (See
Figure 10). This can be loosened with a hand
Wrench or a Socket whichever is easier for you
(See Figure 10). Some times it is easier to test fit
the Tube End of Driveshaft to the Pump while the
Pump is on the bench.
Spacer (2)
Installing Pump:
1.
Install Pump into Splined Clamp Yoke. Slide
the Pump Splined Shaft into the Spline Clamp Yoke
(See Figure 11). Leave the Bar stuck in through the
Yoke as shown, this helps to stabilize the Yoke as
you slide Shaft into the Yoke. Once Pump is slid into
the Splined Yoke, keep the Pump supported; DO
NOT let the Pump hang on the Yoke unsupported.
2.
Pump / Driveshaft Yoke Gap Adjustment.
After sliding Pump Shaft into Splined Clamp Yoke,
the Pump and Yoke must be slid apart far enough to
allow for a 1/16" to 1/8" Gap between them. The
Yoke edge cannot touch the Pump Housing; it will
damage the Housing and the Yoke if it does. This is
a very critical adjustment (See Figure 12).
3.
Tighten Clamp Yoke. After Gap between
Yoke and Pump has been adjusted tighten the Bolts
& Nuts on the Clamp Yoke (See Figure 12 & 13).
Check Pump to Yoke Gap once more. Keep Pump
Supported do not let it hang on Yoke.

Mount Pump to Pump Plate.
Remove the Bar that is slid through the Driveshaft Yoke and push
the Pump inward (See Figure 14). This will make the two piece Driveshaft slide together allowing the
Pump to be pushed towards the tractor. Do this untill the Pump is against the Pump Plate (See Figure
15).
6.
Install Pump Mounting Bolts. While holding in on the Pump (See Figure 15) start the two Pump
Retaining Bolts. Make sure both Bolts are started well before you stop supporting pump. The Bolts should
be snugged untill pump sits level before you stop supporting it (See Figure 16). Let go of the Pump, it
may slide back some and leave a slight gap between Pump and Mounting Plate (See Figure 16).
7.
Tightening Pump Mounting Bolts. There is a shoulder on Pump Flange that must line up through
hole in Pump Mounting Plate (See Figure 14), if the Pump is slid back as in figure 14 try to push it inward
untill it is against Pump Mount Plate as shown (See Figure 15). Slowly and alternating from Left to the
Right side, tighten the Pump mounting bolts untill they are tight. DO NOT FORCE Pump through Pump
Mount Plate, if it will not freely slide in check for a problem of some kind. Excess force could damage
Pump Housing. (See Figure 16). Do Not remove any Plastic caps from Pump inlet or outlet at this time,
keep all openings plugged and sealed to keep them clean.

2. Install Cables Through Floor. Inspect under
the floor and between floor mat and floor on the
RH side of cab for any lines, wires or braces that
Cup Holder
might be under it. Using a 2" hole saw cut a hole
Bracket
through floor mat and floor in a place where saw
will not hit anything on under side of floor. (See
Figure 1
Figure 2). Before running cable through floor
mark the cable on both ends with identifications
(numbers or what you want) so the cables can be
identified as to which is which from either end.
Run the cables and wire harness through the
hole that was cut in the floor and floor mat.
3. Install Boot over cables and wire harness.
There is a boot that is in mount kit that will slide
down over the cables and the wire harness. Make
certain the cables and wire harness are inserted
far enough into the cab to mount to remote
control handles later after they are bolted to the
2" Hole

Cylinder Control Valve.The Cylinder control
valve is shipped with the fittings already assembled
to it. The control valve will be shipped un attached
to anything (See Figure 11). The Control valve will
bolt to the valve mount bracket using three mounting
bolts (See Figure 12 & 13). The bracket will then
bolt to the Versa Mount frame. Look on top of the
versa frmae there will be a lug with two bolt holes
weled to the versa frame. The valv emust be
mounted in such a way thar the spools (where the
Cables connect point toward the cab of the tractor.
the fittings on the valve will point away from the
tractor, this will allow you to stand facing the tractor
and work on the valve and will keep the control
cablse from making a 90 degree bend. (See Figure
13 & 14)
Figure 11
12.
Adjust the Control Handles to a Neutral
Position. The Handles can be adjusted to a neutral
position by going to the control valve. Loosen the
flange bolts and the jam nut at the top of the flange
sleeve. Turn the flange sleeve and this will move the
control handles. The will allow the control handles to
be aligned evenly. Tighten the jam nut and flange
bolts when the handles are adjusted to the desired
position (See Figure 10)
13.
Check the Three Retaining Bolts. The
threaded portion of the three retaining bolts will stick
out of ther nuts at the RH hand side of control handle
mount, these can be cut off with a hack saw if
desired (See Figure 9).

Cylinder Control Valve Installation
Cylinder Hydraulic Control Circuit: (See Figure 11 thru 21)
14.
Hydraulic power for the cylinder control circuit is taken from the second (smaller) stage of the
hydraulic pump. Oil is supplied through hose 2 to the four spool control valve where it is directed
to the appropriate cylinder through the cylinder hoses. All of the cylinders are double acting. The
system is protected from excessive pressure by an adjustable pressure relief valve located on the
inlet section of the valve. The pressure relief valve is factory set at 2000 PSI for the booms. In
addition, at least 3 individual cylinder circuits are protected by a non-adjustable work port relief valve
(See Specifications in the Service repair Manual).
15. One way restrictors are added to the valve sections such that the return flow from the
cylinders when performing gravity aided function will slow the flow of return oil and allow for a more
controllable movement of the boom. (See the specifications for size of restriction and location in
the Service repair Manual).
16. Oil is returned from the valve through Return hose to the Cutter / Motor Control valve where
it then passes through Return hose into the return filter and into the tank.
17. The valve utilized on the Versa Boom mower to facilitate the control of the boom movement
functions, open center, sectional, manually operated valve. The manual operation is performed with
the use of normal directly attached valve handles or through the use of cables and remote
mechanical levers.
18. Although similar in appearance, each valve section is specifically designed to perform the
specified function for which it is assigned. The Valve is shipped assembled and should not be
disassembled during unit assembly.
19. Hydraulic Cylinder Hoses. The Hoses for the Hydraulic Cylinders will be marked with bands
that have the Part Numbers on them. These part numbers will vary with the size of the Boom Model.
The 28 ft. model will have more hoses for the Boom Extend Function, the model with the Hydraulic
Door on cutter head willhave more hoses. To find which Hose you have you will need to consult the
Parts / Operators manual. When connecting the Hoses to The Valve use these numbers to connect
the correct hoses to the correct ports. It may be required that you do some tracing of hoses to find
which hose is hooked to which end of a Cylinder. Listed below is a list of which end of Hydraulic
Cylinder should be connected to which Port on valve. (See Figure 2 & 3)

You must consult the Parts Manual to determine correct Hoses used on the Model you have. Also
the type Head used will make the Hose vary. There is a Electrical control valve Option, this will make
a difference of which hose is connected where. If the hoses are connected to the wrong side of valve
it should not damage any thing, it will mean that the control lever function will be reversed or may not
work at all because the Relief Valve is in the wrong direction of Oil Flow to operate.. Changing the
Hoses on the hose ports of the valve will change this.

The Standard Tandem (Dual) Pump System is Shown, there is a Single Pump System Option
available. The Single Pump only supplies the Hydraulics for the Cutter Head Motor and the Tractor
Hydraulic System is used to supply the Boom Cylinder movements. The Schematic is very much the
same except the Cylinder Control Valve Hose connections are run to and from the tractor instead of

The Control valve will bolt on the top of the
Frame on the right hand side. There is a tab welded
to the Frame that has two holes in it, the Valve mount
plate will bolt to this tab and the valve will bolt to
mount plate (See Figure1 6) The Valve in Figure 6
shows the Hoses and Control Cables already connected, this is for illustration only. The Control Cables
and Hoses are connected after the Valve is bolted to
the mount plate. Most of the Hoses shown in figure
6 are running from the Boom. These Hoses must be
connected to the correct Port on the valve and to the
correct side to operate correctly.
Cylinder Hydraulic Control Circuit:
Figure 16
(See Figures 17)
The Hydraulic Schematic above shows a 4 Spool System. When you assemble this you will not have
to assemble the Valve, it will come to you already assembled as a 4 Spool valve assembly. Hoses must
be connected to the correct Valve Port so the Control Funtions will operate in the correct direction (See
Figure 18)

Wire Harness:
1.
(Standard Mechanical Valve)
Starter Safety Switch Schematic, Mechanical Cable Operated Valve Type,
2.
Figure 4 illustrates a common wire harness connection for Versa Boom mowers with
mechanical cable controls.
3.
Individual installations may vary and are dependent on the electrical and safety system
designs of the tractor to which the mower is mounted.
4.
Consult the specific mounting instructions to determine the correct wire routing for each
specific unit. To ID wires and components of tractor ignition system consult the tractor manufactures manuals.
Common Problems:
1.
The tractor won’t start: The mower on/off switch, if left in the “on” position will not allow the
tractor to restart. Be sure to push the switch into the “off” position and account for all the tractor
safety interlocks to enable the tractor to start. Failure of the tractor starter safety lock system is
normally attributed to a failure of the mower on/off switch. Check continuity at the switch. Check
for loose connections.
2.
Cutter motor won’t start: Normal causes of this type of malfunction include failure of the
push/pull switch, failure of the solenoid coil, loose connections, loss of ground, or a blown fuse.
If the mower won’t start, check continuity of the system with a test light to find an electrical problem.
Problems may also exist in the cutter valve and other systems.
3.
The problem may not be in the electrical system, but because there are so many
connections that could be malfunctioning it is the best place to start checking. If the electrical
connections are ok, go on to the Tractor connections and/or the Tractor components to check for
the malfunction. Some times the service technician thinks the best way to eliminate the Mower
electrical connection problem is to bypass them; this should never be done, eliminating the starter
safety system is dangerous and hard on the Hydraulic System, The Hydraulic System will be trying
to start at a low RPM which is not good.
Standard Control Valve Operation:
1.
This Control valve is the Standard 4 Spool that is remote cable Controlled, The 28 ft model
used a 5 Spool valve with the 5 Th. Spool operating the Boom Extension. THIS SECTION
WILL NOT apply to the OPTIONAL ELECTRONIC JOYSTICK CONTROLS. This Section
mostly shows the 4 Spool Valve, The 5 Spool Valve is mainly the same with the 5 Spool
operating the Hydraulic Door option on the Rotary head or the Boom Extension Cylinder on
the 28-ft Model. (See Figure 5 & 6)

Section 6 - 11
Cylinder Control Valve Installation
REMOTE CABLE OPERATION AND INSTALLATION:
1.
Remote operation of the boom movement control valve can be achieved with the use of cables
and remote actuator handles. The remote operation system is standard equipment on cab tractor
units and can be installed on ROPS tractors as well (See Figure 4). Four cable lengths are available
and should be ordered based on the length required to reach from the valve to the Operator’s location
with out binding or kinking. Cable lengths are limited to 48,60,72 and 102 inches.
2.
To install the cables to the valve, each valve section will require a cable installation kit (4 kits for
a 4-spool valve.). Each individual valve connection kit can be ordered using part number 02971274.
Figure 4 displays the contents of each kit. Cables are not included in Cable Connection Kit.

Option Joystick Mounting
Installing Joystick Mount to Tractor Seat:
1.
Remove Tractor Seat Cushion. Remove
Lower Seat Cushion from Tractor Seat. The Seat
Cushion should have three phillips head screws
across the front edge (See Figure 2). Once these
screws are removed, lift up on the front of the Seat
Cushion which should slide forward and out.
2.
Joystick Bracket mounting holes. The
three mounting holes are already in the Standard
Seat Mounting Plate. If a custom Seat or for some
reason these three holes have to be drilled, use
caution not to drill them in to where the bolts will
interfere with the Tractor Seat Slide Adjustment
Rail.
FIGURE 2
3.
Bolt Mounting Bracket to Seat. Insert
the three 5/16" Bolts with Flatwashers on them
through the holes in the Seat Plate (See Figure 4).
The Mounting Bracket is under the Seat Plate as
shown in the drawing. Install the three 5/16" Locknuts on the Bolts from the Bottom. Tighten the
three Bolts and nuts.
4.
Re-install Tractor Seat Cushion. Reinstall Tractor Seat Cushion in reverse of step 1.
Test Seat to make Sure that it does not bind when
slid forward or back as adjustment. If there is a
Bind, check and correct problem.

are threaded so no Nuts are needed. Tightened the two retaining Bolts (See Figure 1
Item 3 and Figure 2).
FIGURE 6
Installing Wiring Harness for
Joystick:
1.
It is recommended that the Wires for
Joystick be connected at the Tractor Ignition
Switch. But they can be connected as explained below. If connected as shown below
Wires must be traced to find the correct
wires.
FIGURE 7
2.
Preparing Tractor Floor Mat. First
thing to do is remove the Battery Cables from
Battery, Do Not perform any work on Tractor
unless this has been done. Raise the Floor
Mat up on the RH Side by the RH Door, You
will need to fold it back approx. 12 to 14 inches
(See Figure 8). DO NOT Tear or Cut any
Holes in Floor Mat, as it will NOT be required.
You will also find a large oblong shaped rubber plug, this will be pulled up later but it is not
necessary at this time.
3.
Tractor Wiring Harness. Under the
Floor Mat on the right hand side you will find a
Tractor Wiring Loom Running across Floor,
remove the plastic cover that is over the wire
loom. Using Tractor Manufacturers Service
Manual Identify Which Wire is in this Loom.

find the wire from the switch that activates the
Starter Solenoid for the Tractor This wire will need
to be cut to form 2 ends. You will need to locate the
Ignition Switch Power Wire; this wire will have
current only when Ignition Switch is on. This Wire
will have a wire Tee’d into it. (See Figure 9)
*
5.
Wire Harness Through Cab. There is a
large rubber plug in floor; this is where the Joystick
wiring harness will be put through the cab floor.
This plug can be pulled up through the floor (See
Figure 10). it will be required to cut a hole in this
plug for the Wire harness to run through.

6.
Insert it Wire harness through Floor
Plug till the 4 wires that are not in the wire Harness
are even with the Floor. The wires that are sticking
out of harness will be run under Floor mat and
under dash panel to switch or connected to the
tractor harness. These wires are made long because of the different places they can be connected on various models.
7.
Connecting Harness Wires. There are 4
wires that must be connected inside Tractor. 1.
Red Wire (power supply), 1 Black Wire (Ground)
and 2 Brown Wires (Neutral Safety Switch). These
will have to be spliced into Tractor circuits. (See
Figure 13).

must be taken when tightening Hydraulic Fittings. Over tightening can cause the fittings to crack and
require replacement. Use recommended hose end torque values found in chart in operators
manual..
3.
The motor for the Ditcher will operate in both directions. It is important to plumb the motor so
that it rotates to deposit the spoil properly. The direction of rotation can be observed by standing
behind the Ditcher Head, beside the right rear tire. If the Ditcher rotates 'clockwise' it is plumbed for
forward rotation and the spoil will be deposited away from the tractor. If the Ditcher is the reverse
design then the proper rotation is counter-clockwise when observed from the rear. Do Not try to
reverse Ditcher from Rotation it was designed for, it will not work. The Forward and reverse Rotation
Models do not use the same Blade Assembly.
4.
Note: The two hoses (P/N 02961054) connecting the main boom to dipper arm are used to
connect the Ditcher motor. The 90 degree fittings attach to the fittings on the main boom and the
straight fittings attach to the 90 degree fittings on the hydraulic motor. See Figure 69 below.

Attach the Timber Cat Head to the boom using the pins included with the head. Be careful not
to damage the pivot bushings in the boom when inserting the pins. Attach the 90° elbow (Item 1) to the
front port of the boom and position it so that it faces down. Attach the 90° end of the return hose (P/N
02973125) to the fitting and attach the straight end to the 90° fitting (Item 2) on the flow divider (if it is not
already connected). Attach the pressure hose (P/N 02973124) to the rear port of the boom and attach
the other end to the 90° elbow (Item 3) on the flow divider (if it is not already attached). (See Figure 6.)
2.
Be sure the hoses are routed as shown in the figure and securly tighten all connections. Stop
here and go to Hydraulic Oil Tank fill setion, DO NOT Start Tractor untill Hydraulic tank has been filled.
Start tractor and move the head tilt through its motions and check for excessive twisting and bending. It
may require many attempts to obtain the optimum hose connection position. Once achieved, start the
tractor and position the head in a safe area for operation, if necessary, baracade the head to prevent
any contact while it is being operated. This unit is dangerous - STAY AWAY - anytime the tractor is in
operation! Turn on the head and bring the tractor engine up to normal operating speed (540 PTO
RPM). Tighten any leaking hydraulic fittings. Caution, too much tightening can cause the fittings to
crack and require replacement. Use recommended hose end torque valves found in the Maintenance
Section.

Fill Hydraulic Tank
Fill Hydraulic Tank with Oil:
1.
DO NOT START TRACTOR until you have
filled Hydraulic Oil Tank to a level as shown in Sight
Glass gauge and fill the Suction Hose to Pump with
Oil (See Figure 6).
2.
Remove Filler Cap. Remove Filler cap only
when ready to fill hydraulic Tank with Oil. Do Not leave
the Cap off and the system Open, always keep sytem
closed when possible. Avoid any oil contamiantion.
(See Figure 1)
3.
Avoid Hydraulic Contamination by filtering
the Hydraulic Oil while filling the Hydraulic Tank. Filter
buggies or carts are commercially available for Hydraulic system clean-up and Oil transfer. These consist of high capacity filter, a Circulating Pump, a Drive
Motor and hoses for connecting to the units hydraulic
system. When adding Oil always use Clean new Oil
from a sealed container, If you suspect the Oil of being
contaminated don't use it. (See Figure 2 & 3). It is best
to always use a filter system when adding even new
oil.
4.
When adding Oil in the field keeping it clean
is critical, do not use dirting funnels or hoses. Do Not
open Hydraulic tank or any contaners unless the
openings have been cleaned first. The outside of the
containers must be clean. If a windy dusty day do not
fill and allow dirt to blow into oil. Always add Oil using
a pump systemwith at least a 10 Micron filter system.
(See Figure 4)

Fill Hydraulic Tank
Fill Hydraulic Tank with Oil:
5.
Fill Tank. Fill the Hydraulic Tank (See Figure
4) Fill tank till the Oil is visable in the sight Gauge (See
Figure 5 & 8). This will fill tank for the start but it will
have to filled again later.
6.
Fill Suction Hose with Oil. Remove the
Suction Hose at the Tank (See Figure 6) and fill the
hose with clean oil, THIS IS A MUST DO. The Suction
Hose must be filled with Oil to prevent Dry strat up of
Pump. Dry start up of PUMP will damage the Pump.
After filling suction Hose reinstall it and tighten down
Hose Clamp. (See Figure 7)

Start-Up Procedures
Start-up Instructions:
1.
Read all safety instructions. Decals on the A-Boom warn you of particular and multiple
Hazards. Many decals are attached close to part of the A-Boom where there is a possible
hazard. Read and make sure you understand the safety messages before you operate the ABoom. Keep all decals clean and readable. Replace lost or damaged decals.
2.
Before operating, read all the safety and operating instructions in the Operator's Manuals for
both the tractor and mower.
3.
When the hydraulic tank has been filled, The Pump Suction Hose filled with Hydraulic Oil and
the mower unit (Head) properly assembled, the unit should be started up. NOTE: Make sure
that no materials, tools, or jacks have been left under the mower head. Make sure the front
and rear of the mower are properly guarded to prevent any foreign objects from being thrown
by the mower. All other workers should be kept a safe distance from the unit before the mower
is started.
4.
Start the tractor and idle at a slow engine speed until oil is being pumped. Check for any leaks,
this is easiest with an assistant watching for leaks. Do not run if Oil is leaking.
5.
Bleed the air out of all hydraulic cylinders one at a time by extending them to their full length. DO
NOT SWING THE BOOM till last and you have gone to the Rest Stop and Support Section for
instructions.
6.
Engage the Cutter Control Valve at low engine rpm and run the mower slowly for a short
period until all air is removed from the hoses. Keep all persons WELL CLEAR of mower since
Blades can THROW OBJECTS with great velocity for a considerable distance! KEEP CLEAR!
7.
Run the mower at a low tractor engine speed until the mower Hydraulic System gets the Air
out off it. Operate at an engine speed that keeps the filter restriction gauge reading in the
"Green Zone". With the hydraulic warm, bring the tractor speed up to normal operating speed.
If the filter gauge reads in the red zone, stop the unit, release all hydraulic oil pressure, and
Check the filter element in the tank mounted filter or any Hose that may be kinked. Restart the
tractor and mower unit and again check the filter gauge (oil must still be hot).
8.
If the filter gauge reads in the red when first started and does not drop as oil warms, then
something is wrong, contaminants have been introduced into the hydraulic system or some
thing connected wrong. You may need to repeat previous steps again until the gauge reads in
the green.
9.
Check the fluid level in the Hydraulic Tank and add oil if required. As the air has been forced
out of the Cylinders and Hoses, it goes into the Hydraulic Tank and reduces the oil level. The
Hydraulic Oil must be at least at the level of the Sight Gauge on the side of the Tank.
10. Basic trouble shooting guide for first start up.
A. Electrical solenoid valve does not work - check wiring, possible faulty switch, possible
faulty solenoid.
B. Pump is making noise - check for obstruction in suction hose and tank suction assembly,
check alignment of pump driveshaft.
C. Cylinders will not raise - hoses from cylinder incorrectly connected to valve bank, pump
not suppling oil.
D. Cylinder rises slowly - hoses from cylinder incorrectly connected to valve bank, work port
reliefs on valve bank set too low - replace as required.
E. Filter reads in red - viscosity of oil too high - wait until oil heats up before checking filter
gauge. If gauge reads in red even after unit is hot, then the filter must be replaced.
11. DO NOT put Boom in transport position without using extreme caution as the Boom Stop has
not been installed. It cannot be installed until after the start-up has been done (See Next Section).

Post-Assembly Check List
Post-Assembly Check List:
1.
Is oil level in the tank even with the sight gauge on the tank?
2.
Has the proper oil been used in the system? Proper oil is Universal Tractor Hydraulic.
3.
Does Boom machine movement match operation decal - Swing, Lift, Dipper, Tilt?
4.
Is control valve free and does not stick?
5.
Are all hoses tight and do not leak?
6.
Are all decals in place? See Safety Section in Manual for decal description and
placement.
7.
Does tractor pass Alamo Group Mower Stability Test?
8.
Have all grease points been adequately greased?
9.
Are all bolts tight?
10.
Have all hoses been properly routed so that hoses do not kink or bend when boom is
articulated through all motions?
11.
Does starter lockout device work correctly on machine? Tractor should not start if
mower switch is on.
12.
Is swing cylinder pinned in correct hole? On rear-swing type machine cylinder should
be pinned to outside hole. On front-swing type machine cylinder should be pinned in
inside hole.
13.
Is machine equipped with proper operator protection? Must have cage or cage panels.
14.
Does mower operate when on/off switch is on? Stop when switch is off?
15.
Is head rotation correct? On rotary heads (looking from the top of the deck) rotation
should be clockwise so that debris will be thrown away from the tractor. On flails,
rotation can be forward or reverse, but forward rotation is standard.
16.
If furnishing a square head, are spindle housing bolts tight? Is spindle assembly tight?
Are bolts that hold blade bar to spindle tight? Checked the lube level in spindle housing?
17.
Does head operate smoothly at normal operating speed? Head should not vibrate
excessively.

Boom Rest Hook plate welded to the boom from the
factory. (See Figure 3).
3.
Swinging Boom. Extreme caution must be
used when swinging Boom, There is NO BOOM
STOP INSTALLED and can not be installed till later.
Slowly swing boom Up and back watching the Cab so
as not to hit it with the Boom. Do nor raise Boom higher
than the inner stop om Boom rest plate bolted to the
top of the Boom rest. Swing Boom till it is aligned in
Boom Rest. The Head should be in the folded position
as you lower Boom (See Figure 3).
Figure 1
4.
Slowly lower the Boom down into Boom
Rest. You will need to take measurement on the Boom
(See Figure 4) here and Mark the Boom so you can
weld on the stop plate to Boom. The Height of the
Boom when in the Boom Rest should not exceed 12
ft. 9 in. max. (See Figure 3).
Figure 2
5.
Boom Swing Stop cannot be installed untill
the boom is setting in the boom rest (See Figure
3). The Boom Stop will have to be welded on the
versa frame behind the Lift Cylinder Lug on the
king post. the purpose of this stop is to prevent
the boom from hitting the cab when moving boom
to transport position.

Restriction Notes:
1. Mount kit designed for right hand, thru-hood exhaust. A-post exhausts may interfere with the
boom and must be modified at the dealer/customer’s expense.
2. Optional Electrohydraulic mount kit does not include a seat-mounted joystick due to the
complicated seat design and/or multiple seat options. Instead, a bracket mounts on the
corner post and positions the joystick comfortably near the seat and console.
3. If an optional wheel weight is desired, the order must include one of the wheel weight adapters
above.
4. Notice that these mount kits can also be used on the John Deere 6615/6715.
5. A Lexan window insert can not be installed with the rear screen due to the glass curvature.
6. The Versa side mount kit is rated for 2wd tractors only. It can only be utilized on a 4wd if the
frame is shifted at least six inches to the right to allow head clearance with the front tire. This
alteration would also necessitate the use of a frame extension on the left for proper oil reservoir
installation.
7. The Right Hand Light will need to be removed and relocated to clear the boom when in the
transprot position. Becasue of the different mounting on tractors this will need to be done by
the dealer and/or customer at their exspense. Note some tractors do not have functioning
RH doors from tractor manufacturer. If this the case the door lock fastener will be mounted
with the same bollts as the lifght, if so this fastener will have to reinstalled to keep door
secured.
8. Driveline must be installed with the universal joints timed to ensure long driveshaft life.
