OPERATION
GENERAL PURPOSE
The 6400 Series Cultivators are intended
to be used for general purpose row crop
cultivation. They can be used for throwing
up beds, mulching existing beds and
incorporating chemicals. These cultivators
with regular equipment are fully tractor
carried when lifted.

LOCAL LAWS WHEN TRANSPORTING
CULTIVATOR ON THE HIGHWAY.
PREPARING THE TRACTOR
It is recommended that tractors
be equipped with Rollover Protective
Protection Systems (ROPS), enclosed
cabs and seat belts be used in operations.
Tractor wheels must be set to run
approximately in the center of the rows.
for example, if crops are planted in 36-inch
(806) 745-0384
Page 8
P/N L50012751
rows, the center of the tractor wheels will be set 72
inches apart. Measure from center to center of tires,
then from center of tires to center of tractor to make
certain the tires are equally spaced from the center.
Weight may need to be added to the front
end of the tractor for transport stability and steering
control when operating. Refer to tractor operators
manual for the correct procedure for adding weight.
NOTE
Front end weight may not always maintain the
required stability if the tractor is driven too fast over
rough ground with the cultivator in raised position.
Be safe and drive slowly under these conditions.
Rear wheel weights may be necessary to
eliminate excessive wheel slippage or for stability in
rough or hillside fields. Refer to your tractor operators
manual to determine the correct amount of weight to
add.
PREPARING THE CULTIVATOR
At the start of each cultivating season, the
following procedures should be carried out.
Clean off any dirt or grease that may have
accumulated on moving parts. This will prevent
abrasive action that could cause excessive wear.
Thoroughly inspect the cultivator for loose or
worn parts and adjust or replace as necessary.
Inspect wheel bearings in gauge wheels and
repack with wheel bearing grease if necessary.
Before operating the Cultivator be sure it
has been properly lubricated as described in the
SERVICE section.
OPERATING SPEED
The operating speed is determined by soil
conditions, plant growth and personal preference.
Speeds of 5-8 miles per hour are usually most
desirable.

CULTIVATING PATTERN
For precision cultivation, the same group
of rows that are planted in one pass across the
field should be cultivated in one pass across the
field, and preferably in the same direction that
they were planted.
NOTE
If hitch components are not centered on tool bar,
it may cause the Cultivator to be unstable when
lifted or cause damage to Cultivator.
HITCH POSITIONS
3-POINT HITCH SELECTION
The position and location of the hitch is
determined by the hitch category of the tractor.
The hitch category may vary from tractor to
tractor. Check the hitch category of the tractor to
be used and refer to STRAIGHT and OFFSET
HITCHES or WIDE SUPPORT HITCH for proper
setup. Be sure when changing tractors to check
that the hitch is set up properly.
There are 3 styles of 3-point hitches
available for the cultivator: the straight hitch (bolt
on), offset hitch (bolt on), and a wide support
hitch (for over 300-inch tool bars). The straight
and offset hitches can be mounted on the tool
bar to allow clearance for components being
attached to the bar. The HITCH CHART below
is used to determine which hitch to use. This will
depend on the category of the tractor hitch, the
row spacing desired and whether used with or
without row gangs.

STABILIZING CULTIVATOR &
TRACTOR
The cultivator can be stabilized to resist
excessive side-sway by using a coulter attachment
or tractor hitch stabilizer (sway bar) attachment.
The coulter attachment is the superior stabilizing
method and is highly recommended for crops
planted on contour or rolling land.
NOTE
Do not install tractor hitch stabilizer (sway bar)
while using a coulter. The cultivator must be
allowed to float sideways within the normal limits
of the hitch.
The folding tool bar allows folding of the
outer portions (wings) for portions (wings) for
easier transporting. Transport braces must be
used and transport pins in place when transporting.
The folding tool bar may be used as a rigid bar by
inserting locking pins. The outer portions (wings)
may be allowed to float by adding optional gauge
wheels to tool bar wings and removing locking
pins, blocks and shims. (Fig. 3)
NOTE
When a coulter is not used, be sure the tractor
hitch stabilizer or sway bar is installed and
properly adjusted.
RIGID COULTER
For most conditions a single rigid coulter (Fig. 4)
located at the center of a 100 inch tool bar will
provide adequate stability. For usual conditions
GAUGE WHEELS
An optional gauge wheel attachment (Fig. 3) is
available. The attachment includes left and right
assemblies (tires not included). Assemblies are
mounted an equal distance from the hitch and
positioned in the row middle. Adjustment may be
required to maintain gang pipes parallel to the
ground. Gauge wheels may be adjusted (raised
or lowered) using the turnbuckle on the arm
assembly. Gauge wheels must be adjusted to
the same height for proper operation.
LEVELING CULTIVATOR
After mounting the cultivator to the tractor, use
the tractor hitch-system to level the tool bar from
side to side. Tractor top link should be adjusted
to position the tool bar in a vertical orientation.

with 188 inch and longer tool bars, two rigid
coulter attachments should be used. When using
two rigid coulters, coulter adaptors are required.
Normal coulter penetration is 3 inches to 5 inches.
On hard soils the coulter should be adjusted to
run only 2 inches to 3 inches deep to prevent the
coulter from holding the gangs out of the ground.
The depth of the rigid coulter is adjusted by raising
or lowering the coulter arms. The coulter blade
can be adjusted right or left by loosening the axle
nut (Fig. 5, Item 1) and by loosening or tightening
the opposing nuts (Item 2) on the axle as shown.
out of the ground. The spring loaded coulter is
adjusted by raising or lowering the set collars on
the spring rods. In soft soils, adjust the coulter to
keep the hub from running in the soil by dropping
the bottom set collars to their lowest point and
positioning the top set collars 5 inches below the
top of the rod. The coulter blade can be adjusted
right or left by loosening the axle nut (Fig. 5, Item
1) and by loosening and tightening the opposing
nuts (Item 2) on the axle as shown.
NOTE
When two or more coulters are used, be sure
NOTE
each coulter is running true and parallel. (See When two or more coulters are used, be sure
above for adjustments).
each coulter is running true and parallel.
SPRING LOADED COULTER
For most conditions a spring loaded
coulter (Fig. 6) located at the center of a 100 inch
tool bar will provide adequate stability. For usual
conditions with 188 inch and longer tool bars, two
spring loaded coulter attachments should be used.
When two coulters are used, coulter adaptors are
required. Normal coulter penetration is 3 inches
to 5 inches. On hard soils the coulter should be
adjusted to run only 2 inches to 3 inches deep
to prevent the coulter from holding the gangs

GUIDE CONES
Guide cones are used in one or more
pairs to provide accurate guidance for precise
cultivation in bedded crops. The guide cone
attaches to the tool bar as shown in Fig. 7 with
the cone riding against the opposite sides of the
bed. The guide cone depth is adjusted by raising
or lowering the guide cone arms.
P.O. Box 3338
Lubbock, TX 79452
NOTE
Due to loads imposed, use two guide cones on 2
and 4 row units; four guide cones on 6 and 8 row
units; and six guide cones on 10 row or larger
units.
Do not operate guide wheels with any other
stabilization device. They tend to operate against
each other and damage may result.
NOTE
Do not operate guide cones with any other
stabilization device. They tend to operate against
each other and damage may result.
Guide wheels are not designed to support the
weight of the cultivator and should never be used
as gauge wheels.
NOTE
NOTE
NOTE
Guide cones are not designed to support the
weight of the cultivator and should never be used
as gauge wheels.
GUIDE WHEELS
Guide wheels are used for precision
cultivation in flat planted or bedded crops. The
guide wheels are mounted on the planter tool
bar as shown in Fig. 8 and make a V-shape
depression in the row middle as the crop is
planted. The small spike runs ahead of the wheel
and loosens the soil so the wheel can penetrate
adequately. The guide wheels are then transferred
to the Cultivator tool bar (Fig. 9) and set to run
in the previously formed V-shaped depression
allowing the row gangs to be set very close to
the crop. The spike is left on the guide wheel
assembly, to give added stability to the cultivator.

SPLIT ROW GANGS
The function of the split row gang (Fig. 10)
is to control weed growth and condition the soil
in the crop row area immediately adjacent to the
crop row. The crop will always be between the
P.O. Box 3338
Lubbock, TX 79452
Page 13
P/N L50012751
split row gangs. There are three types of row
gangs, the split row gangs with straight tines
(Fig. 11, Item 1), the slicer tine split row gangs
(Item 2) and disc row gangs (Item 3). The two
halves of these row gangs can be used in a
number of positions. For certain conditions, such
as crust breaking, spider gangs are mounted
close-in and without any angle, so they will run
straight. In some types of soil, when heavy rains
follow closely after planting, it is desirable to run
spider gangs opposite the normal direction to
penetrate the heavy crust and lift them off the
row. NOTE: Soil must be fairly free from trash
and hard clods for this operation. A variety of
settings may be obtained by experimentation
to fit individual crop and soil conditions. A wide
range of spacing between the inner spiders of the
gang halves may be obtained by using the slots
ih the beam plates and the holes in the row gang
arms. The beam plates may also be mounted in
alternate positions on the beam when necessary.
To initially set the spring tension on the
row gang support, position the top set collar 2
inches below the retaining nut at the top of the
spring rod. Position the bottom set collar 3 inches
above the lowest point. This is a good starting
position for a cultivator in flat planted crops.
Additional adjustments may be necessary to
refine the settings for inidividual crops and fields.
The spring pressure is increased by raising the
bottom set collar. For additional pressure, the
sping rod is transferred to the additional hole in
the lower parallel linkage. The split row ganags
are adjusted according to the type split row gang,
crop, condition and operation being performed.
For typical settings of split row gangs in small
crops, large crops and bed planted crops see
CULTIVATOR ADJUSTMENTS. When the crop
becomes too high to use the row gangs, the entire
row gang and support assembly should be removed
from the tool bar in order to permit maximum
clearance for late cultivation with the rear gangs.
REAR GANGS
The function of the rear gang (Fig. 12) is to
remove weed growth, mulch and condition the
soil in the area between the crop rows. There are
three types of rear gangs, the 14.5 inch slicer
tine rear gang (Fig. 13, Item 1), 16 inch slicer
tine rear gang (Item 2) and 16 inch disc gang
(Item 3). The slicer tine gangs are less sensitive
to the angle of operation and work best where
high residue does not exist. The disc gangs work
good in high residue and are more aggressive,

yet more sensitive to the angle at which they
operate. The operation and setup of these
gangs is the same, except for the angle of the
gangs.
NOTE
In order for cultivator to operate properly be sure
that all slicer tine gangs are of the same size.
Gang pipes (Fig. 14) must be parallel
with the ground in order for the row gangs to
penetrate the soil correctly. Adjust the tractor top
link until the tool bar is vertical with the ground
as shown in Fig. 14.To initially set the spring
tension on the long gang pipes, position the top
set collar so that the setscrew is seated in the
depression provided in the spring rod. Adjust
the bottom set collar up until the spring is held
firmly, but not compressed. To set the short gang
pipes, position the top set collar to its highest
position and tighten. Adjust the bottom set collar
to leave 1/4 inch movement of the spring. These
settings are good starting positions for cultivators
in flat planted crops. Additional adjustment may
be necessary to refine the setting for individual
crops and fields. The rear gangs are adjusted
according to the type split row gangs, crop,
condition and operation being performed. For
typical settings of rear gangs see CULTIVATOR
ADJUSTMENTS. For setting of rear gangs
when mulching beds se BED MULCHING.

SLICER TINE SPLIT ROW GANGS
A typical setting for cultivating small crops
is shown in Fig. 15. The split row gangs (No.
1 on the right and No. 2 on the left) should be
adjusted with the rear of the spiders angled to
the inside to throw soil toward the crop. The rear
gangs (No. 1 on the left and No. 2 on the right)
should be angled sufficiently to remove all weeds
as the gangs slice the soil away from the crop. A
level seedbed can be easily maintained with this
setting by using sweeps on the end of the long
row pipes to sweep the middles and push some
soil back toward the crop. This setting allows
high speed cultivation.
A typical setting for cultivating large crops
A typical setting for cultivating bed
planted crops is shown in Fig. 17. The split
row gangs (No. 1 on the left and No. 2 on the
right) should be adjusted with the front of the
spiders angled slightly to the inside to move
soil and weeds away from the crop. The rear
gangs (No. 1 on the right and No. 2 on the left)
are positioned on the pipe supports so that
all spiders or disc penetrate the soil an equal
depth. The gangs should be angled sufficiently
to remove weeds while moving the soil toward
is shown in Fig. 16. The split row gangs (No. 1 on
the left and No. 2 on the right) should be adjusted
with the front of the spiders angled suffiently to
the inside to remove all weeds while moving the
soil away from the crop. The rear gang (No. 1 on
the right and No. 2 on the left) should be angled
sufficiently to slice out the weeds while moving
the soil toward the crop. Sweeps may also be
used with this setup.

the crop. For furrow or lister planted crops the
No. 1 gang should be on the left and No. 2
gang on the right, in order to move soil up the
hill. For crops such as Irish potatoes, do not
run the inside spiders or disc of rear gangs
too close to the crop. Sweeps may also be
used with this setup.
DISC ROW GANGS
(Repair Parts Only)
A disc row gang is used when precision
is desired in barring off small crops. A typical
setting for cultivating small crops is shown in
Fig. 18. The disc row gangs should be angled
to throw dirt away from-the crop and should
be moved toward the crop until the desired
condition is achieved. A single disc on each
gang may be used instead of two by using a
spacer. A disc and a spider may be used on
each gang if desired. The rear gangs (No. 1
on the left side and No. 2 on the right) should
be angled sufficiently to remove all weeds as
the gangs slice the soil away from the crop. A
level seedbed can be easily maintained with
this setting by using sweeps on the end of
(806) 745-0384
705 E. Slaton Rd.
the long row gang pipes to sweep the middles
and push some soil back toward the crop. This
setting allows high speed cultivation.
BED MULCHING
For mulching heavily crusted beds
with large weed growth, refer to Fig. 19. Bed
rippers are recommended for shaving the bed
tops instead of the split row gangs. The rear
gangs (No. 1 on the right and No. 2 on the left)
should be set at the maximum angle possible
and tilted so that each spider penetrates the
bed an equal depth.
Under less extreme conditions the rear
gang angle and pressure are less and the split
row gangs can be used satisfactorily to tear
down the bed tops. The split row gangs should
be set the same as for use with bed planted
crops. When the row gangs are used to mulch
the bed tops, the pressure spring must not
run completely compressed and the spiders
should not run completely compressed and the
spiders should not be run up to the hubs. This
would result in damage or excessive wear. The
rear gangs should be positioned so they work
as near to the bottom of the bed as possible.
To fully mulch the furrows between the beds,
a sweep should be used in the bottom of the
furrow as shown in Fig. 19.

P/N L50012751
INCORPORATING CHEMICALS
The 6400 Series Cultivators can be used
to incorporate chemicals in either a band or
broadcast.
For broadcast incorporation in bedded
crops (Fig. 20), the split row gangs should be set
close together and angled to throw soil out from
the center. The rear gangs (No. 1 on the right
and No. 2 on the left) are positioned on the pipe
supports so that the spiders penetrate the same
depth. The gangs should be angled to move soil
back towards the center and to lap over in the
middle. In flat planted crops, the gangs will be set
the same as for bedded, except gangs are not
angled on gang pipes.
For band incorporation mount a long
gang pipe over each row and two rear gangs
(No. 2 in front and No. 1 in rear) on the pipe
about 4 inches apart as shown in Fig. 21.
Angle the gangs about 5 degrees in opposite
directions so that rear gang picks up soil moved
by front gang and places it back into desired
band while thoroughly mixing the chemical with
the soil. As a general rule, run the spiders twice
as deep as the level of incorporation desired.
GANG EXTENSION ATTACHMENT
(Repair Parts Only)
A gang extension attachment (Fig.
22) is used to extend the position of the rear
gangs laterally. A gang extension attachment
is required for each pair of gangs. The gang

extension bracket is attached to the pivot clamp
and rear gang as shown. The rear gangs and
extension brackets are then adjusted to obtain
the proper setting.
ADD ON SPIDERS
Optional add on spiders (Fig. 23) are
available for the No. 1 and No. 2 rear gangs.
The spiders are primarily used in conditions
where spiders tend to clog. In this condition the
scrapers are more effective if a spider is added
on the right side of the No. 1 gang and the left
side of the No. 2 gang.
NOTE
SWEEP SHANKS
Sweep shanks (Fig. 24) are available
to be used with the standard support bundles
(Fig. 25). The sweep shanks are mounted on
the end of the long pipes and centered between
the rows. The sweeps are adjusted by raising or
lowering the shank and tightening in place. When
cultivator is fitted with appropriate sweeps, the
sweeps will leave a slight furrow in the middle
to help the driver guide the tractor accurately on
the next cultivation. Sweep shanks also provide
additional cultivation, especially when the rear
gangs are set so that they do not overlap. Large
sweeps may be used to keep water furrows
open for flood irrigation practices.
Threaded spider No. 1 should only be added to
No. 1 gangs and threaded spider No. 2 should
only be added to No. 2 gangs.

A rigid shank (Figure 24, Item 1) is for use
in clean soils. The trip foot shank (Item 2) is used
in soils where rocks, stumps, etc., are present and
some degree of protection is needed to prevent
the sweeps from hanging on these obstacles.
To adjust the trip foot shanks for more or less
resistance and loosen for less. The spring shanks
(Item 3) are used in conditions where maximum
protection of sweeps from underground obstacles
is desired. High speed sweeps (Item 4) are used
for high speed operation where the sweeps slice
through the soil without moving too much soil to
each side. The high speed sweep is especially
useful in narrow row spacing.
BED RIPPERS
Bed rippers with clamps are mounted
to the tool bar and used to shave the top of
heavily crusted, weedy beds during bed mulching
operations. They can also be used in the tractor
row middle to loosen heavy crust left by previous
planting or cultivation. A variety of chisels or
sweeps can be used on the bed ripper. The bed
rippers are adjusted by raising or lowering the
shanks and tightening in place.
NOTE
The tool bar has not been designed to use
deep penetrating tools in each row. When
the above tool is used in every row, the cable
attachment must be used to prevent the tool
bar from bending. (Fig. 53)
TRIP FOOT BED RIPPER (Figure 26)
Adjust the trip setting by applying only
enough torque to keep the foot from tripping in
clean soil. Applying too much torque to the trip bolt
will not allow the foot to trip when an obstruction
is encountered.

COIL SPRING BED RIPPER (Figure
27)
Coil shanks (Fig. 27) are recommended
for use behind the tractor tires in rocky soils. The
coil shank is mounted to the tool bar with the
same clamp but the spacer (Fig. 27) is required
in the clamp to allow interchangability of different
bed ripper shanks.
HEAVY DUTY CROP SHIELD
The heavy duty crop shields (Fig. 28)
are mounted directly to the pipe supports and
adjusted for desired ground clearance. The
heavy duty shields give more crop protection
used as a crop shield, the adjustable panel is
raised to its maximum height.
DISC WEEDER
A disc weeder (Fig. 30) is used over the
row for more precise weed control than can be
accomplished with the split row gangs. The disc
weeder and clamp are usually mounted in front of
the tool bar with the disc toward the front. It can
be mounted behind the tool bar, with the disc to
the front when front mounting interferes with the
tractor. Install knives (not included) on the shanks
behind the disc. Adjust the disc and the knives to
the same depth or the disc may be run slightly
deeper than the knife. Running the knife deeper
than the disc has generally proven unsatisfactory.

disc. Run the disc about 1-1/2 inches deep.
TWIN DISC ROW ATTACHMENT
The twin row disc attachment (Fig. 31) is
used to cultivate twin row patterns and can be
adjusted to handle up to 14 inch spacing.
The gauge wheel is mounted on the front
bar of the frame so that the wheel is positioned
to run between the twin rows. The discs are
mounted on the first and second bar so they are
staggered to reduce the possibility of stalks or
other residue contacting both disc at the same
time. Run the disc about 1-1/2 inches deep and
slightly angled to cut out a groove for the knives
that follow. Mount the hoe shank assemblies
and knives (not furnished) on the second, third
and fourth bars at the same depth as the disc
or slightly shallower. Run the vertical side of the
knife in the deepest part of the groove cut by the
disc.
The depth of the disc can be controlled by
adjusting the gauge wheel. Adjust the downward
pressure by moving the set collars on the rod for
more or less pressure.

support the cultivator when removed from the
tractor. After hitching and lifting the cultivator,
raise the pipe stand and pin in position. Two
stands are required, one on each side of the tool
bar.

The granular fertilizer attachment is
designed to fit the Bigham Brothers/Lilliston 6400
Series Rolling Cultivator with a 7 x 7 toolbar. It
is located to the rear and above the toolbar (see
Figure A).
It is best to first assemble the cultivator
complete with all optional attachments before
attempting to mount the granular fertilizer
attachment.
If optional banding attachments are to
be used, these should also be placed loosely
on the toolbar. The split row gang and bed
ripper attachments may not be used with any
main toolbar mounted banding attachments.

FERTILIZER TOOLBAR
The fertilizer toolbar is mounted to the 7
x 7 toolbar using the toolbar mounting bracket
(Figure B), clamp 3/4 x 9” carriage bolts, 5/8”
U-bolt, nuts and lockwashers. The number of
toolbar mounting brackets required is one (1)
more than the number hopper assemblies.
The right outside mounting bracket should
be mounted to the inside and as close as possible
to the last long gang pipe assembly on the right
end of the tool bar (Figure A).
The left outside mounting bracket should
be placed to the inside of the last gang pipe on
the left end of the tool bar but placed as close to
the hopper assembly as space allows.
On a two row cultivator (one hopper), these
two will be the only mounting brackets used. On a
four row cultivator (two hoppers), one additional
bracket will be placed near the center of the
cultivator where space is available on either side
of the 3-point hitch mast. On a six row cultivator
(three hoppers), two additional brackets will be
placed between each hopper for a total of four
brackets. These will be placed between the 4th
P.O. Box 3338

the row width conversion factor on the rate chart.
To change sprocket ratios, remove chain
from sprockets, remove clip pins, holding sprocket

sprocket with L.H. jackshaft sprocket. (Figure N)
6.
If the pounds per acre from steps 4 or 5 is
less than desired, increase the auger setting or
change to a higher drive ratio. If rate is higher than
desired, decrease the auger setting or change to
a lower drive ratio.

ROW WIDTH CONVERSION
If you are planting on a row spacing other
than 36”, you must convert the rate chart to your
row spacing. Divide the rate desired on your row
spacing by the conversion factor for your row
spacing from the row width conversion chart
above. This will give you an equivalent rate per
acre on 36” rows for your desired rate. Select the
auger RPM and auger index from the chart which
corresponds to the equivalent rate.

OPTIONAL APPLICATOR ATTACHMENTS
DUAL OPENING KNIFE — The dual opening
knife requires one of long knife shank and one 7x7
bracket to mount to the front or back of the 6400
series 7x7 tool bar. One per row or one for every
two rows should be used for double application of
fertilizer. (Figure P)
LEFT AND RIGHT HAND INJECTOR KNIVES
— The left and right hand injector knives are
designed to be mounted on the 6400 series 7x7
tool bar. Two long knife shanks and two 7x7
brackets must be ordered to attach the injectors
to the tool bar. The injectors will band fertilizer
in the ground and to the side of the row ahead
of the spider gangs. NOTE: Shanks can be
mounted behind tool bar if desired by reversing
the tool bar clamp. (Figure Q)

DOUBLE DISC APPLICATORS — The double
disc applicators and bracket mount to the 6400
series 7x7 tool bar. They are designed for
conditions where a rigid fertilizer applicator would
be damaged due to ground conditions. Double
disc applicators may be used in pairs with a ‘Y”
divider for banding on each side of the row or they
may be used for banding on only one side of the
row. (Figure R)
SPOUT HOLDERS — The spout holders are
designed to be used on the 6400 series rolling
cultivator spider gangs when it is desirable to
broadcast fertilizer along the row when cultivating
the crop. Position the spout holder so fertilizer
will be mixed with the soil uniformly when spiders
pass over the fertilizer band. (Figure 5)

FOOT SUPPORT AND SINGLE SHANK
APPLICATOR — The foot support and the single
shank applicator is designed to mount on the 6400
series rolling cultivator. The standard support is
mounted in front of the spider gang on the gang
pipe when it is desirable to band fertilizer to the
side of the row and ahead of the gang. (Figure
T)
“Y” DIVIDER AND HOSES -- The “Y” divider is
designed to split the discharge from each spout
on the hopper. This allows fertilizer to be banded
on each side of two rows. The large end of the
fertilizer tube is to be stretched over the square
tubing and fixed with hose clamps. (Figure U)
