The model SG-26 requires a tractor of at least 22 hp or
up to a maximum of 45 hp and a Category I, 3 pt. hitch.
The model SG-36 requires a tractor of at least 45 hp or
up to a maximum of 100 hp and a Category I or II, 3 pt.
hitch.
The tractor also needs lift arm stabilizer bars or sway
blocks to control side movement of the stump grinder.
Adjust as tightly as practical for best performance.
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 specifica-
tions and adjustment instructions – available from most
farm equipment dealers.)
Tractor must be equipped with two (2) independent pair
of remote hydraulic outlets to operate these stump
grinders.
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.
Keep foldable ROPS systems in “locked up” position at all
times. Contact your local dealer for a ROPS for your
tractor.
Most swinging drawbars will have to be moved to a
forward position or removed.
Check the tractor swing-
ing drawbar for interference with the front of the stump
grinder. The swinging drawbar can be moved forward on
some tractors or it can be removed.
It is recommended that only tractors with wide front
axles be used with these stump grinders. Tricycle front
wheel arrangements are inherently unstable and tractor
roll-over accidents are more likely to occur.
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.
Figure 1.
Tractor Stability
When using the unit, 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 equipment. DO NOT GUESS
OR ESTIMATE!
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.
The operator is responsible for the safe operation of this
stump grinder. The operator must be properly trained.
Operators should be familiar with the stump grinder and
tractor and all safety practices before starting operation.
Read the safety rules and safety signs on pages 5-15.
