The Rotary Tillers require a category I 3-pt. hitch trac-
tor from 15 to 55 horsepower depending on the specific
tiller model (see chart – page 2). The tractor must be
equipped with a 540 rpm PTO (power takeoff) in good
working condition.
It is recommended that only tractors with wide front
axles be used with the tiller. Tricycle front wheel
arrangements are inherently unstable and tractor
roll-over accidents are more likely to occur.
The tractor also needs lift arm stabilizer bars or sway
blocks to control side movement of the tiller.
Check the tractor’s 3-pt. hydraulic lift system. Refer to
your tractor operator’s manual or dealer for any adjust-
ments necessary to put the hydraulic system in good
working order. (I&T shop manuals will list most specifi-
cations and adjustment instructions - available from most
farm equipment dealers.)
Be sure tires and rims are in good condition. Inflate
tires to the proper recommended air pressure.
Check the tractor master shield over the PTO stub
shaft. Make sure it is in good condition and fastened
securely to the tractor. Purchase a new shield if old
shield is damaged or missing. (You may have to use a
tractor salvage yard for replacement parts on older
tractors.)
It is recommended that a ROPS (Roll-Over Protection
Structure) and a seat belt be installed on all tractors.
Contact your local dealer for a ROPS for your tractor.
A S S E M B LY
This unit is shipped almost completely assembled.
Carefully follow instructions for final assembly.
Before attempting assembly check the following items.
Having all the needed parts and equipment readily at
hand will speed up your assembly task and will make the
job as safe as possible.
• Check for fasteners and pins that were shipped with
the tiller. All hardware coming from the factory has
been installed in the location where it will be used. If a
part or fastener is temporarily removed for assembly
reasons, remember where it goes. Keep the parts
separated.
• Have a fork lift or loader along with chains and safety
stands that are sized for the job ready for the assem-
bly task.
• Have a minimum of 2 people at hand during assembly.
• Check to see that all nuts are tightened. Refer to the
Torque Values Chart on page 25.
C A U T I O N !
Be sure your tractor is in good condition. Read all
the safety precautions and make sure all tractor
operators are familiar with the safety rules of
operation.
C A U T I O N !
To avoid bodily injury caused by accidental falling
of tiller, securely support tiller on safe supporting
stands or blocks!
Figure 1. Tractor Stability
W A R N I N G !
When using 3 pt. hitch equipment, a minimum 20%
of tractor and equipment weight must be on tractor
front wheels. Without this weight, tractor could tip
up, causing possible loss of control and possible
personal injury or death. The weight may be attained
with a front end loader, front wheel weights, ballast
in tires or front tractor weights. When attaining a
minimum 20% of tractor and equipment weight on
the front wheels, you must not exceed the ROPS
weight certification. Weigh the tractor and equip-
ment. DO NOT GUESS OR ESTIMATE!
W A R N I N G !
A heavy load can cause instability in driving a
tractor. Make sure the front of the tractor is properly
counterbalanced with weights. Always drive slowly -
especially around turns. An unstable tractor could
steer badly and possibly tip over, causing injury or
death.
I N S T R U C T I O N S
The operator is responsible for the safe operation of this
tiller. The operator must be properly trained. Operators
should be familiar with the tiller and tractor and all safety
practices before starting operation. Read the safety rules
and safety signs on pages 6-15.
