OPERATING INSTRUCTIONS
1. 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.
2. 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 adjusted
in the same 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.
3. Raise the tiller and remove the blocks.
4. With the tractor at idle RPM and the tiller lifted off the
ground, engage the PTO and slowly advance throttle
to 540 PTO RPM.
5. 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.
6. 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.
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.
3. Check tiller tines for cracks and breaks before every
use.
4. Slip clutch operational check. After the implement
has been stored for thirty days or more perform the
following operational check.
a. Loosen bolts and lock nuts progressively until
tension is relieved.
b. To aid in determining slippage, scribe/mark a
line across clutch plate and Belleville Spring.
c. With tractor at idle speed, engage tractor PTO
drive 2-3 seconds. Clutch should slip without
turning blades.
d. 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.
OPERATING/MAINTENANCE
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.
NOTE: While this is a good starting point,
further adjustments may need to be made
based on soil conditions.
IMPORTANT:
Slip clutch components must
be free to rotate when necessary. After thirty
days or more, linings of slip clutch may draw
moisture. Linings may bond to metal parts
causing slip clutch to be ineffective, resulting
in machine damage.
