The warning system in this manual identifies potential
hazards and has special safety messages that help you and
others avoid personal injury, even death. DANGER,
WARNING and CAUTION are signal words used to
identify the level of hazard. However, regardless of the
hazard, be extremely careful.

DANGER signals an extreme hazard that will cause
serious injury or death if the recommended precautions
are not followed.
WARNING signals a hazard that may cause serious injury
or death if the recommended precautions are not followed.
CAUTION signals a hazard that may cause minor or
moderate injury if the recommended precautions are not
followed.
Two other words are also used to highlight information.
“Important” calls attention to special mechanical
information and “Note” emphasizes general information
worthy of special attention.
The left and right side of the machine is determined by
sitting on the seat in the normal operator’s position.

Stability Ratings
1. Position the tiller on a level surface with enough space
behind it to accommodate the traction unit.
To determine the degree of slope you can traverse with the
tiller installed on a traction unit, find the stability rating
for the hill position you want to travel in the table below,
then find the degree of slope for the same rating and hill
position in the Stability Data section of the traction unit
operator’s manual.
Orientation
2. Move pump control lever to slow (turtle) position.
3. Start the engine.
4. Slowly push the attachment tilt lever forward to tilt the
attachment mount plate forward.
5. Position mount plate into the upper lip of the
attachment receiver plate (Fig. 2).

6. Raise the loader arms while tilting back the mount
plate at the same time.
Note: The tiller is rated for use without the counterweight.
If you use the counterweight with the tiller, the traction
unit will be less stable in the front and side uphill
positions.
IMPORTANT: The attachment should be raised
enough to clear the ground and the mount plate tilted
all the way back.
7. Stop the engine.
WARNING
8. Engage the quick attach pins (Fig. 3).
POTENTIAL HAZARD
• Exceeding the maximum slope can cause the
traction unit to tip.
1
WHAT CAN HAPPEN
• If the traction unit tips, you or bystanders could
be crushed.
HOW TO AVOID THE HAZARD
• Do not drive the the traction unit on a slope
steeper that the maximum slope.

Installing the Tiller on the
Traction Unit
Connecting the Hydraulic
Hoses
IMPORTANT: Before connecting any attachments to
the traction unit, ensure that the mount plates are free
of any dirt or debris.
1. Stop the engine.
4
2. Move the auxiliary hydraulic lever forward, backward,
and back to neutral to relieve hydraulic pressure at the
hydraulic couplers.
7. Start the engine, tilt the mount plate forward and back
the traction unit away from the tiller.
IMPORTANT: Ensure that all foreign matter is
cleaned from hydraulic couplers.
Operation
3. Remove protective covers from hydraulic couplers on
the traction unit. Connect covers together to prevent
contamination during operation.
Tips for Tilling
• Clean the area of trash, branches, and rocks before
tilling to prevent equipment damage.
4. Slide the collars back on the hydraulic couplers and
connect the attachment couplers to the traction unit
couplers.
• Always begin tilling with the slowest ground speed
possible. Increase speed if conditions permit.
5. Ensure that the connections are secure by pulling on
the hoses.
• Always use full throttle (maximum engine speed).
• Till in long, straight passes. Do not make turns while
the tiller is in the ground, as equipment damage may
result.
WARNING
POTENTIAL HAZARD
• Hydraulic fluid escaping under pressure can
penetrate skin and cause injury.
• Avoid excessive tilling of the soil, as finely tilled soil
will not absorb moisture easily and puddles of water or
run-off may occur.
WHAT CAN HAPPEN
• Fluid accidentally injected into the skin must be
surgically removed within a few hours by a
doctor familiar with this form of injury, or
gangrene may result.
• When tilling hard packed, very dry, or virgin soil, raise
the tiller so only the very top of the soil is penetrated.
On succeeding passes the depth may be lowered.
• Run the tiller so that the dirt is thrown away from you.
HOW TO AVOID THE HAZARD
• Keep body and hands away from pin hole leaks
or nozzles that eject high pressure hydraulic
fluid.
• Use cardboard or paper to find hydraulic leaks,
never use your hands.
• If a rock or other obstruction gets into the tiller tines,
reverse the rotation direction to dislodge it.
Removing the Tiller from the
Traction Unit
1. Start engine and lower the tiller to the ground or onto a
trailer.
2. Stop the engine.
3. Move the auxiliary hydraulic lever forward, backward,
and back to neutral to relieve hydraulic pressure at the
hydraulic couplers.
4. Disengage the quick attach pins by turning them to the
outside.
5. Slide the collars back on the hydraulic couplers and
disconnect them.
IMPORTANT: Connect the attachment hoses together
to prevent hydraulic system contamination during
storage.
6. Install the protective covers onto the hydraulic
couplers on the traction unit.

CAUTION
POTENTIAL HAZARD
• If you leave the key in the ignition switch, someone could start the engine.
WHAT CAN HAPPEN
• Accidental starting of the engine could seriously injure you or other bystanders.
HOW TO AVOID THE HAZARD
• Remove the key from the ignition switch before you do any maintenance.
Greasing and Lubrication
Lubricant Type: Commercial chain lube.
Service Interval/Specification
1. Lower the loader arms and stop the engine. Remove
the key.
Grease the 2 tiller shaft fittings every 25 operating hours.
Grease immediately after every washing.
2. Remove the chain drive cover (Fig, 4).
3. Apply a commercial chain lube onto the chain spans.
Grease Type: General-purpose grease.
4. Install the chain drive cover.
How to Grease
Adjusting Tiller Drive Chain
Tension
1. Lower the loader arms and stop the engine. Remove
the key.
2. Clean the grease fittings with a rag.
4. Connect a grease gun to each fitting.
Adjust the tiller drive chain after the initial 5 hours of
operation and every 25 operating hours thereafter. There
should be 1/2–3/4 inch slack in the chain, measured
mid–way between the sprockets.
5. Pump grease into the fittings until grease begins to
ooze out of the bearings.
1. Lower the loader arms and stop the engine. Remove
the key.
6. Wipe up any excess grease.
2. Remove the chain drive cover (Fig, 4).
Lubricating Tiller Drive Chain
3. Loosen the 2 hydraulic motor, mount plate bolts
(Fig, 4).
Lubricate tiller drive chain after the initial 5 hours of
operation and every 25 operating hours thereafter.
4. Using the adjuster bolt, move the hydraulic motor
upward to tighten the chain (Fig, 4).
3. Scrape any paint off the front of the fittings.

Storage
3. Adjuster bolt
1. Before long term storage wash the tiller with mild
detergent and water to remove dirt and grime.
5. After proper chain tension is attained, tighten the
adjuster bolt and hydraulic motor mount plate bolts
(Fig, 4).
2. Check the condition of the drive chain. Adjust and
lubricate the chain.
Note: When proper adjustment can no longer be attained
from the adjuster bolt or repeated chain failures occur,
replace chain.
4. Check and tighten all bolts, nuts, and screws. Repair or
replace any part or tines that are damaged or worn.
6. Install the chain drive cover.
5. Paint all scratched or bare metal surfaces. Paint is
available from your Authorized Service Dealer.
Tiller Tine Replacement
6. Store the tiller in a clean, dry garage or storage area.
Cover the tiller to protect it and keep it clean.
3. Grease all fittings.
Check and replace tines when they become worn or dull.
Worn or dull tines will degrade the performance of the
tiller.
