Installing the Tine Attachment
1. Move the two PTO Power Unit swingout bolts
outward and slide the washers up against the
bolt heads.
2. Remove the support block from under the
engine and slowly roll the power unit back
next to the tine attachment. Place the support
block back under the engine.
3. Remove the dust cap (or protective wrapping)
from the dog clutch coupling on the tine
attachment.
4. Carefully align the guide pin on the PTO
Power Unit with the alignment hole in the tine
attachment and bring the two units together.
See Figure 4-24.
5. Move the two swing-bolts into the slots of
the tine attachment. Alternately tighten each
bolt until they are tight enough to make the
concave washers flat. The bolts must be very
tight — if you have a torque wrench, tighten
each bolt to between 70 and 80 ft.-lbs.
NOTE: The swing-bolts must be kept very tight
to prevent damaging wear to the dog clutch
coupling, alignment pin or the alignment hole.
Check the bolt tightness every 2-1⁄2 operating
hours.
6. Remove the engine support before moving
the tiller in a forward direction.
Moving the Tiller
When the engine is running, the tiller's powered
wheels make moving the tiller to and from the
garden easy. If the engine is not running, set the
Wheel Speed Lever to FREEWHEEL position to roll the
tiller to another location.
1. Place the Tines/PTO Clutch Lever in
DISENGAGE position.
2. Move the Depth Regulator Lever down all the
way into the Travel setting.
3. If using engine power, move Wheel Speed Lever
to either SLOW or FAST, and use the Wheels/
Tines/PTO Drive Lever to drive the wheels.

WARNING! To help avoid personal injury
from revolving tines, always put the
Tines/PTO Clutch Lever in DISENGAGE
position before transporting, loading, or
unloading tiller.
4. If the engine is stopped, move Wheel Speed Lever
to FREEWHEEL, and manually push the tiller.
Loading & Unloading the Tiller
The following provides information on tiller loading,
unloading, and requirements before loading and
unloading the tiller. Read the following instructions
carefully before attempting to load or unload your tiller.
Follow these steps before loading or unloading the Tiller:
• Ramps must be strong enough to support
the combined weight of the tiller and the
operator. They should provide good traction
to prevent slipping; they should have side rails
to guide the tiller along the ramps; and they
should have a locking device to secure them to
the vehicle.
• Operators should wear sturdy footwear that
will help to prevent slipping.
• Turn the vehicle's engine off and apply its
parking brake.
• Position the loading vehicle so that the ramp
angle is as flat as possible (the less incline to
the ramp, the better).
Loading the Tiller
1. Use loading ramps that are strong and wide
enough to safely hold the weight of the tiller
and the operator combined — your tiller
weighs between 280 and 325 lbs.
2. Move the Tines/PTO Clutch Lever into
DISENGAGE position.
3. Set the Depth Regulator lever to the Travel
position.
4. Move Wheel Speed Lever into SLOW position
and reduce the engine throttle speed.
5. Shift the Wheels/Tines/PTO Lever into
FORWARD position and follow the tiller up the
ramps. Check the wheels as you move the tiller
forward. Ensure that they move up the center
of each ramp.
6. Prevent the tiller from rolling in the vehicle.
Leave Wheel Speed Lever in FAST or SLOW
position, chock the wheels with blocks and tie
down the tiller.
Unloading the Tiller
NOTE: Never unload the tiller in FORWARD drive. The
tiller could tip forward and expose you to the tines
(which should be disengaged as instructed).
1. Use loading ramps that are strong and wide
enough to safely hold the weight of the tiller
and the operator combined — your tiller
weighs between 280 and 325 lbs.
2. Move the Tines/PTO Clutch Lever to
DISENGAGE position.
3. Set the Depth Regulator Lever to the TRAVEL
position.
4. Move Wheel Speed Lever to SLOW position
and reduce the engine throttle speed.
NOTE: Look behind you before you back
down the ramp to ensure that all is clear. While
descending, keep checking for obstacles
behind you.
5. Move and hold the Wheels/Tines/PTO Lever
into REVERSE drive and back down the ramps.
Check the wheels as you move the tiller
backward. Ensure that they move down the
center of each ramp.
