WHEEL BOLTS
It is recommended that all wheel bolts be
checkedfor tightness beforeusing and again
after one day of use. Check periodically to
be sure the wheel bolts are tight.
LUBRICATION
Make sure the disk cultivator is properly
lubricated.
HYDRAULICS
Check wing lift and depth control cylinders
for proper alignment and operation. On any
machine,checkthat thehydraulic systemhas
been properly charged and purged.
When tightening bolts, they must be torqued
to the proper number of foot-pounds as
indicated in the table unless specified. It is
important that all bolts be kept tight.
On new machines, all nuts and bolts must
be rechecked after a few hours of operation.
When replacing a bolt, use only a bolt of the
same grade or higher. Except in shear bolt
applications, where you must use the same
grade bolt.
Bolts with no markings are grade 2
Grade5 boltsfurnished with the machineare
identified by three radial lines on the head.
Grade8 boltsfurnished with the machineare
identified by six radial lines on the head.
All U-bolts are grade 5.
TIRE INFLATION
The use of proper air pressure is the most
important factor in satisfactory performance
and maintenance of implement tire.
Underinflation will damage the cord body of
thetire andcause aseries ofdiagonalbreaks
in the fabric sidewall area.
Ifthe tirebuckles or wrinkles,the air pressure
must be increased to the point where the
sidwall remains smooth while operating.
Check the air pressure every two or three
weeks and do not allow the pressure to drop
to a point where buckling or wrinkling of the
tire may be possible.
Note: Do not inflate tires beyond the
specified tire pressure.

TRACTOR REQUIREMENTS
TRANSPORTING
ASMV (Slow Moving Vehicle) emblem must
be used at all times while traveling on public
roads.
The implement must always be placed in
transport position and the cylinder channel
locks used when traveling on public roads.
Never depend on your tractor’s hydraulic
systemto carrythe weight whiletransporting.
Note: Use extreme caution when
working around overhead power
transmission lines.
Note: Always install lock channels
in the main lift cylinders for road
transport.
Reduce speed when cornering and when
traveling over rough and/or uneven ground.
Drive at a reasonable speed to maintain
complete control of the machine at all times.
Comply with your state and local laws
governing highway safety when moving
machinery on a highway.
BEARING ASSEMBLIES
IMPORTANT: The spindle nuts on
the wheel assemblies are preset at
the factory.
Roadtransport and field workingwill seat the
bearings and will require additional
adjustment. After 20 hours of machine
operation remove the grease cap and check
the bearing tightness.
Removethecotterpin androtatethetirewhile
tightening the spindle nut. Tighten until the
drag on the tire stops the rotation. Locate
the cotter pin hole in the spindle and loosen
the spindle nut just enough to allow insertion
of the cotter pin. Replace cotter pin and
grease cap.
The WIL-RICH Disk Cultivator requires
approximately 10 to 12 horsepower per foot.
Three remote cylinder outlets and controls
are required. Best results will be achieved
whenoperatingspeed of6 to8 milesper hour
is maintained.
WHEELS AND TIRES
Dual tractor rear wheels are recommended
for use with the Disk Cultivator. See your
tractors operator’s manual for tire inflation
and instructions for wheel ballast where
required.
METERING VALVES
The metering valve may be set to provide
varying amounts of hydraulic oil flow to the
cylinders (see your tractor operator’s
manual.)
It is recommended the wing lift cylinders run
as slow as possible to prevent damage to
the implement, persons and property. Turn
wing lift hydraulics metering values to slow
position.
FRONT BALLAST
Tractorfrontend stabilityis necessaryforsafe
and efficient operation. Therefore, it is
important that the proper amount of weight
be installed on the front of the tractor as
recommended in your tractor operator’s
manual.
Note: Ballast recommendations
provide for adequate transport
stability at recommended speeds.
Additional front ballast may be
required for satisfactory field
operation due to sudden or extreme
forces on the Disk Cultivator. These
forces may occur when removing
the Disk Cultivator from the ground
and turning at rows end, or during
field transport over very rough
ground.

Themain frame depthon the WIL-RICHdisk
cultivator is controlled by a pair of 12.56”
strokebypasscylinders.These cylindersare
locatedatthe rearof theunit, abovethe main
frame lift axles. The cylinders are tied to the
main axle and to the main axle mast. The
mainaxle mastis non-adjustableand pinned
to the front of the main frame through the
main axle tie tube. See Fig 1.
The main frame depth is mechanically set by
turningthe screw collar “DOWN” the cylinder
rod to decrease the working depth or “UP”
thecylinderrodtoincreasetheworkingdepth.
An add-on stop collar is provided for
situations where the screw stop collar does
not allow a shallow enough setting.
NOTE: Proper field operation is
dependent upon the screw collars
of the main frame lift cylinders being
first to contact the mechanical
stops. If a wing cylinder screw stop
collars contacts first the leveling
function of the system will not
operate correctly.
NOTE: The cylinder screw stop
collars on the main frame depth
control cylinders must be set equally
– failure to do so can twist the main
axle and cause axle failure. Measure
the collar locations or count the
number of turns each screw collar
is rotated to ensure they are set the
same.
Note: The main and wing lift
cylinders need to be positioned with
the rod end of the cylinder attached
to the axle as shown.
The top bypass cylinders have adjustable
mechanical screw collars. These screw
collarsare rotatedon thecylinder rod to vary
theretracted length ofthe cylinder,providing
themeans to adjust the working depth of the
unit.

The operational depth of the wing is
controlled by use of a 10.8” stroke slave
cylinder located above the wing axle. These
cylinders are connected in series with the
main frame lift cylinders. The cylinders are
attached to the wing axle mast, through the
wingaxle tie tube andto the front ofthewing.
See Fig. 2.
NOTE: The screw collars and stop
collars are used to set the depth of
the wing. Adjustments to level the
wing relative to the main frame are
made at the front of the unit.
Byadjustment ofthewing adjustmentrodthe
wing can be adjusted to the main frame. To

rod (counter clockwise rotation as viewed
from the front of the machine) will lower the
wingandadjusting therod (clockwiserotation

shorter position will raise the wing. To
maintain the front to rear level of the wing
the front gauge wheel will also need to be
adjusted. Refer to the preliminary and field
settings for additional setting information.

LEVELING
Theoperational leveling of the field cultivator
mustbe done ina level area ofthe field. Final
front to rear and side to side leveling is done
at working depth. Preliminary setting can be
completed in the yard to speed up the field
setting operation.
The front to rear level of the main frame is
controlled by the main axle lift wheels and
the setting of the main hitch. The front to
rearlevel ofthe wing iscontrolled by thewing
axle lift wheels and the hydraulic front gage
wheel. Both the main frame and the wings
will need to be adjusted correctly for proper
operation.
PRELIMINARY SETTINGS
Proper preliminary and field settings will
require use of a measuring device. Once the
unit has been properly assembled and
hitchedto the tractorthat will beused for field
operation,make certainthe hydraulicsystem
has been properly charged. Position the unit
on a level area of ground and unfold the
wings, checking to ensure there are no
people or obstructions in the path of the
wings.
NOTE: Cycle the main lift hydraulics
a number of times to remove air in
the system. Holding the hydraulic
lever in the “RAISE” position will
remove the unwanted air from the
circuit.
Lower the unit to the ground so that the front
row of shanks on the main frame are 1”-2”
above the ground.
Measure the main frame height from the
ground to the top of the outer frame tube and
compare to the distance measured from the
ground to the top of this outer frame tube at
the rear of the machine. See fig 4.
The depth control cylinders are hooked in
series. Eachcylinder isa topbypass cylinder
and when fully extended will pass oil by the
piston into the next cylinder charging the
system.
Topbypasscylinderswill bypassoil whenthe
cylinder is fully extended. This bypass
condition will exist when the implement is
raisedto maximumgroundclearance. At this
timeoil will passthrough a 1/16" diahole and
go on to the next cylinder. See Fig. 3.
Note: This system requires periodic
raising of the unit and holding of the
tractor valve to expel air or
contaminants. 3/8" HOLE

Note: To synchronize or re-
synchronize the bypass system, the
tractor control valve must be held
in the raised position until the entire
implement is raised and any air that
may be in the lines has been
expelled.
