OPERATING INSTRUCTIONS
1. Before each use, perform all necessary maintenance
described in maintenance section on this page.
2. Read, understand, and follow the safety information
pertaining to training, preparation, starting and
stopping, operation, transportation, maintenance
and storage at the beginning of this manual.
3. With the rotary tiller positioned on level ground,
adjust the tractor lift arms so that when lifted, the
rotor bar remains parallel to the ground.
4. With the rotary tiller attached to the tractor, raise
and support the tiller with suitable blocks. Adjust
the skids, located on the sides of the tiller. The
adjustment bolts for both right and left sides should
be positioned in the same adjustment hole. This
allows the tiller to till the same depth on each side.
Adjust the rear guard assembly, with regulating
chain, until the desired mulching effect is found.
5. Raise the tiller and remove the blocks.
6. With the tractor at idle RPM and the tiller lifted off of
the ground, engage PTO and slowly advance throttle
to 540 PTO RPM. NOTE: Rotary tiller is designed to
run at 540 PTO RPM only.
7. Select a low gear for the tractor and begin to move
forward. Tractor ground speed is to be controlled
by gear selection only and not engine speed. As the
tractor moves forward, slowly lower the tiller down.
Allow the tiller tines to gradually engage the ground.
IMPORTANT:
Do not allow the tractor engine
or rotary tiller to bog down or stall. This causes
undue wear and tear on the tiller and tractor. If this
continues to happen reduce ground speed and raise
tilling depth of rotary tiller. Never attempt to remove
objects from the rotor bar until the tractor has
been shut down and the tiller tines have completely
stopped.
IMPORTANT:
Never travel at a fast ground speed
while using the tiller,as this could damage it. Never
attempt to turn the tractor or travel in reverse with
the PTO engaged and the tiller in the ground. Always
raise the tiller out of the ground when backing up
or attempting to turn. Failure to do so may cause
damage to the tiller.
8. After each use clean all debris from the tiller tines.
Replace any missing or illegible safety decals.
Inspect for any damaged or worn parts and
replace before next use. Store rotary tiller in a dry
environment.
OPERATING/MAINTENANCE
WARNING
Never attempt to adjust the rotary
tiller while the tractor is running.
MAINTENANCE
1. Periodically check and maintain proper gear oil level.
2. Every 8 hours, grease: (1) outboard hub, (2) PTO shaft
universal joints, (3) PTO shaft safety shield and (4)
PTO telescoping surface.
NOTE:
Use only a grade Type II tube grease. Do not
grease the slip clutch assembly.
3. Before each use check to make sure all safety shields
are installed and working properly.
4. Check tiller tines for cracks and breaks before every
use.
5. Periodically check all nuts and bolts to ensure they
are tight and secure.
6. Periodically loosen torque spring bolts and allow slip
clutch to slip for approximately two (2) revolutions.
Loosen the bolts until the springs lose contact with
the flange yoke. This ensures that the slip clutch is
not in a “locked” position.
7. Make sure that the clutch slips.
8. To retighten the slip clutch, tighten the torque spring
bolts until the nut makes contact with the flange yoke
and further tighten one and a (1 1/2) half turns. While
this is a good starting point, further adjustments may
need to be made based on soil conditions.
NOTE:
Do not over or under tighten slip clutch
assembly or damage may occur.
