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.

Do not attempt any makeshift repairs to the
hydrauliclines,fittingsorhosesbyusingtape,
clamps or cements. The hydraulic system
operates under extremely high-pressure.
Such repairs will fail suddenly and create a
hazardous and unsafe condition.
Wear proper hand and eye protection when
searching for high pressure leaks. Use a
piece of cardboard as a backstop instead of
hands to isolate and identify a leak.
If injured by a concentrated high-pressure
stream of hydraulic fluid, seek medical
attention immediately. Serious infection or
toxicreactioncan developfromhydraulicfluid
piercing the skin surface.
STORAGE SAFETY
Store unit in an area away from human
activity.
Do not permit children to play around the
stored unit.
Store in a dry, level area. Support the base
with planks if required.
TIRE SAFETY
Failure to follow proper procedures when
mountingatire ona wheelor rimcan produce
an explosion which may result in serious
injury or death.
Do not attempt to mount a tire unless you
have the proper equipment and experience
to do the job.
Have a qualified tire dealer or repair service
perform required tire maintenance.
Stop tractor engine, place all controls in
neutral, set park brake, remove ignition key
and wait for all moving parts to stop before
servicing, adjusting, repairing or unplugging.
Do not attempt to remove any obstruction
while machine is in motion.
HYDRAULIC SAFETY
Always place all tractor hydraulic controls in
neutral before dismounting.
Make sure that all components in the
hydraulic system are kept in good condition
and are clean.
Relievepressure beforeworking onhydraulic
system.
Replace any worn, cut, abraded, flattened or
crimped hoses and metal lines.
Beforeapplyingpressuretothesystem,make
sure all components are tight and that lines,
hoses and couplings are not damaged.
