disengaged, the parking brake is on and the right
foot pedal is in the neutral position.
2. Do not allow children to operate the machine.
Do not allow adults to operate the machine
without proper instruction.
2. Do not run the engine in a confined area without
adequate ventilation. Exhaust fumes are hazardous and could possibly be deadly.
3. Remove all debris or other objects that might be
picked up and thrown by the cutter blades. Keep
all bystanders away from the mowing area.
3. Using the machine demands attention. To
prevent loss of control:
A. Mow only in daylight or when there is good
artificial light.
B. Watch for holes or other hidden hazards.
C. Do not drive close to a drop-off, ditch, creek
bank, or other hazard.
D. Reduce speed when making sharp turns and
when turning on hillsides.
E. Do not operate where conditions are slippery.
4. Keep all shields, safety devices, and decals in
place. If a shield, safety device or decal is defective or damaged, repair or replace it before
operating. Also, check all nuts, bolts and screws
for proper tightness, to assure the machine is in
safe operating condition.
5. Do not operate the machine while wearing
sandals, tennis shoes, sneakers or shorts. Also,
do not wear loose fitting clothing which could get

9. If the cutting blades should strike a solid object
or the equipment should start to vibrate abnormally, stop the engine, disconnect the spark plug
wire, and check immediately for the cause.
Vibration is generally a warning of trouble.
Check the machine for damaged or defective
parts. Repair any damage before starting the
engine or operating the cutter deck. Be sure the
blades are in good condition and the blade bolts
are tight.
MAINTENANCE AND STORAGE
10. Reduce speed and exercise extreme caution on
slopes and in sharp turns to prevent tipping or
loss of control. Be especially cautious when
changing directions on slopes.
3. To reduce potential fire hazard, keep the engine
free of excessive grease, grass, leaves and accumulations of dirt.
1. Disconnect the spark plug wire from the spark
plug to prevent accidental starting of the engine
when servicing, adjusting or storing the machine.
2. If the mower must be tipped to perform maintenance or adjustment, remove the battery, drain
the gasoline from the fuel tank and the oil from
the crankcase.
4. Be sure the machine is in safe operating condition
by keeping nuts, bolts, and screws tight. Check
the blade mounting bolts and nuts frequently to
be sure they are tightened.
WARNING:
DO NOT operate on steep slopes. To check a
slope, attempt to back up it (with the cutter deck
down). If the machine can back up the slope
without the wheels slipping, reduce speed and
use extreme caution. ALWAYS FOLLOW OSHA
APPROVED OPERATION.
5. If the engine must be running to perform a
maintenance adjustment, keep hands, feet, clothing and other parts of the body away from the
cutter deck blades and other moving parts.

MOWER OPERATION
1. Read and understand the safety instructions
before attempting to operate this machine.
10. Be careful when servicing the battery as it contains acid, which is corrosive and could cause
burns to skin and clothing.
2. Before starting the engine:
* Check the oil level in the engine and the
hydraulic reservoir.
* Fill the fuel tank with clean, fresh, lead-free
gasoline.
* Open the fuel valve on the bottom of the
fuel tank.
11. Batteries release explosive gases when being
charged or discharged. Keep batteries away from
any source of sparks and/or flame.
12. Make sure all hydraulic connections are tight and
all hydraulic hoses and lines are in good condition before starting the machine.
-NOTEUse gasoline with an octane rating no less than
87.
13. Hydraulic fluid is under high pressure. If you
need service on your hydraulic system, please see
your authorized Scag dealer.
* The right hand foot pedal must be in the
NEUTRAL position.
* The blade clutch switch must be in the OFF
position.
* The parking brake must be ON.
INITIAL RUN-IN PROCEDURES
(FIRST DAY OF USE OR APPROXIMATELY 10 HOURS)
3. Start the engine:
1. Check the belts for proper tension at 2, 4 and 8
hours. Adjust as needed. (See Belt Tension,
page 7).
* Choke as required. If the engine is cold, pull
the choke knob out. When the engine starts,
slowly push the choke in. If the engine stalls,
repeat the above operation. When the engine
is warm, choking may not be necessary.
2. Check the neutral adjustment. (See Adjustments, page 6)
3. Check the tires for proper pressure.
Caster Wheels
25 psi.
Drive Wheels
15 psi.
Rear Steering Wheel 15 psi
4. Depress the left hand operator presence pedal.
5. Engage the cutter blades by lifting and pushing
the blade cluch switch into the ON position. Pull
the switch to the OFF position to disengage the
cutter blades.
4. Check for loose hardware. Tighten as needed.
5. Check the safety switches for proper adjustment:
-NOTEWhen the PTO is engaged or (possibly) disengaged, a squealing sound from the underside of
the machine is normal. It is caused by the
electric clutch plates meshing as the cutter
blades come up to speed. For best equipment
life, engage the clutch with the engine at 1/2
throttle, not under full load.
* The engine should crank and start if the
machine is in neutral, the PTO engagement switch is OFF and the parking brake
is ON.
6. Apply lubricant to all the grease fittings. Lubricant was applied at the factory. This is just a
precautionary check to make sure that all the
fittings have been lubricated.
4
7. To "freewheel" or move the machine around
without the engine running, rotate the dump valve
lever located on the left rear of the engine deck to
the freewheel position (See Figure 3). The lever
must be returned to the drive position to operate
the machine.
WARNING:
If you are not familiar with the operation of the
hydrostatic drive, practice turning and maneuvering before engaging the cutter blades.
5. Release the parking brake. Depress the right
foot pedal at the toe end to drive forward (See
Figure 1) or depress the pedal at the heel end to
drive in reverse. (See Figure 2)

ADJUSTMENTS
PARKING BRAKE
Minor brake adjustments can be made by loosening the top nut on both brake cables (see figure
4). Back the nuts off approximately 1/4". While
pulling one cable downward, tighten the bottom
nut on the cable until it touches the bottom of the
brake cable mount. Tighten both the top and
bottom nuts to lock the cable in place. Repeat
the above steps for the second brake cable. Make
sure that both cables are adjusted evenly so that
the brakes do not cause the mower to pull to the
left or right.

6. When driving over curbs, disengage the cutter
blades, raise the cutter deck to clear the curb.
Drive forward over the curb. After the curb is
clear lower the cutter deck back to normal
operating position. Be sure to leave slack in the
cable after lowering the cutter deck.

-NOTEThis is a minor brake adjustment. If the
brakes do not function properly after this
adjustment, see your Scag Service Dealer
before operating your mower.
4. If the drive wheels rotate in the forward travel
direction, turn the adjustment bolt clockwise until
the tire rotation stops. If the drive wheels rotate
in the backward travel direction, turn the adjustment bolt counter-clockwise until the tire rotation stops (See Figure 5).

5. Check the adjustment of the right foot control
pedal for full forward speed. The pedal should
rest on the foot plate when the pump is stroked in
the full forward position. To make an adjustment, disconnect the ball joint from the pedal arm
and loosen the jam nut (See Figure 6). Place the
foot control pedal forward against the foot rest
and adjust the ball joint on the rod until the stud
aligns with the hole in the arm. Bolt the ball joint
to the arm and tighten the jam nut.
2. Block the caster wheels to prevent an accident
should the machine fall off the jack stands.
3. Start the engine and determine if the drive wheels
rotate.
If the drive wheels consistently rotate when foot
pedal control is in neutral, go to step 4.
If the drive wheels inconsistently rotate, i.e. drive
wheels sometimes rotate and sometimes do not
when foot pedal is not depressed, then check
neutral adjustment bolt for "zero free play" in

-NOTEFor best results, keep the cutter deck
high in relation to the engine deck and
the blades low in the cutter deck; ie. 4 or
5 spacers below the spindle shaft.
CUTTER DECK ADJUSTMENTS
Due to the many conditions that exist, it is difficult
to suggest a setting that will work for every lawn.
There are, however, two adjustments that should be
made on the cutter deck: pitch and height.
PITCH is the angle of the blades (comparing front
to rear).
Additional range to the cutting height can be
achieved by repositioning the cutter deck in relationship to the engine deck. This adjustment also affects
the pitch of the deck.
HEIGHT is the nominal distance that the blade is
off the ground. This measurement is made with the
blades pointed side to side and distance is measured
between cutting tip and ground.
There are three positions for mounting the cutter
deck (See Figure 11). For cutting in the lowest
position, mount the cutter deck in the top hole (A).
For cutting in the highest position, mount the deck in
the lowest hole (C). Setting the cutter deck height
will be determined by the type of cutting conditions.
Adjusting the blade height can be done by moving
any number of the five smaller spacers on the blade
mounting bolts to the top of the spindle shaft or to
the bottom of the spindle shaft. All blades should be
positioned equally (See Figure10).

B
The unit is shipped with one spacer on top of spindle
and four underneath (See Figure 10).

This adjustment does not affect blade pitch.

STEERING CABLE ROUTING
Pin
Spacers
When the steering cable is routed between the
front pulley and the rear steering collar, it is very
important that the cable does not rub where it
crosses. The top of the cable end from the front
pulley must go over the top of the lower cable
end (See Figure 14). The cable should be tightened until the slack has been removed. The cable
should not be under tension. Do not overtighten
the adjusting nuts on the rear steering collar
pulley.

LIMITED WARRANTY-COMMERCIAL EQUIPMENT
Any part of the Scag commercial mower manufactured by Scag Power Equipment and found, in the reasonable judgment of Scag, to be defective in materials or workmanship, will be repaired or replaced by an Authorized Scag Service
Dealer without charge for parts and labor. This warranty is limited to the original purchaser and is not transferable.
Proof of purchase will be required by the dealer to substantiate any warranty claims. All warranty work must be
performed by an Authorized Scag Service Dealer.
This warranty is limited to the following specified periods from the date of the original retail purchase for defects in
materials or workmanship:
* Wear items including drive belts, blades, hoses and tires are warranted for 90 days.
* Batteries are covered for 90 days.
* Frame, deck, and structural components including oil reservoir, fittings, and oil cooler
are warranted for 1 year.
* Engines and electric starters are covered by the manufacturers warranty period.
* Drive system components are warranted for 1 year by the component manufacturer, in
conjunction with Scag Power Equipment. (Excluding fittings, hoses, cooling system,
oil reservoir, drive belts).
* Electric clutches have a Limited Warranty for 2 years (Parts and labor 1st year; Parts
only 2nd year).
* Cutter Spindle Assemblies 46631 have a Limited Warranty for three years (Parts and
labor 1st year; Parts only 2nd and 3rd year).
Any Scag product used for rental purposes is covered by a 90 day warranty.
The Scag mower, including any defective part must be returned to an Authorized Scag Service Dealer within the
warranty period. The expense of delivering the mower to the dealer for warranty work and the expense of returning it
to the owner after repair will be paid for by the owner. Scags responsibility is limited to making the required repairs
and no claim of breach of warranty shall be cause for cancellation or rescission of the contract of sale of any Scag
mower.
This warranty does not cover any mower that has been subject to misuse, neglect, negligence, or accident, or that has
been operated in any way contrary to the operating instructions as specified in the Operators Manual. The warranty
does not apply to any damage to the mower that is the result of improper maintenance, or to any mower or parts that
have not been assembled or installed as specified in the Operators Manual and Assembly Manual. The warranty does
not cover any mower that has been altered or modified, changing performance or durability. In addition, the warranty
does not extend to repairs made necessary by normal wear, or by the use of parts or accessories which, in the reasonable
judgment of Scag, are either incompatible with the Scag mower or adversely affect its operation, performance or
durability.
Scag Power Equipment reserves the right to change or improve the design of any mower without assuming any obligation to modify any mower previously manufactured.
All other implied warranties are limited in duration to the one (1) year warranty period or ninety (90) days for mowers
used for rental purpose. Accordingly, any such implied warranties including merchantability, fitness for a particular
purpose, or otherwise, are disclaimed in their entirety after the expiration of the appropriate one year or ninety day
warranty period. Scags obligation under this warranty is strictly and exclusively limited to the repair or replacement
of defective parts and Scag does not assume or authorize anyone to assume for them any other obligation. Some states
do not allow limitations on how long an implied warranty lasts, so the above limitation may not apply to you.
Scag assumes no responsibility for incidental, consequential or other damages including, but not limited to, expense for
gasoline, expense of delivering the mower to an Authorized Scag Service Dealer and expense of returning it to the
owner, mechanics travel time, telephone or telegram charges, rental of a like product during the time warranty repairs
are being performed, travel, loss or damage to personal property, loss of revenue, loss of use of the mower, loss of time
or inconvenience. Some states do not allow the exclusion or limitation of incidental or consequential damages, so the
above limitation or exclusion may not apply to you.
This warranty gives you specific legal rights, and you may also have other rights which vary from state to state.
