SAFETY INSTRUCTIONS
(continued)
PTO powered stump grinder’s operating power is supplied from tractor PTO. Refer to your tractor manual for
PTO engagement and disengagement instructions. Always operate PTO at 540 RPM. Know how to stop trac-
tor and stump grinder quickly in case of an emergency.
The addition of a separate over-running PTO clutch attachment will change the length of the PTO driveline.
Pay extra attention to the instructions on PTO driveline installation.
Separate over-running clutch attachments will increase the length of the driveline and may cause the front
knuckle joint to operate beyond the cover of the tractor master shield. This is NOT recommended and will
present a dangerous operating condition.
The use of this equipment is subject to certain hazards which cannot be protected against by mechanical
means or product design. All operators of this equipment must read and understand this entire manual,
paying particular attention to safety and operating instructions, prior to using. If there is something in this
manual you do not understand, ask your supervisor, or your dealer, to explain it to you.
Keep all helpers and bystanders at least a hundred feet (100 ft.) from an operating stump grinder. Only prop-
erly trained people should operate this machine.
The majority of accidents involve entanglement on the driveline, injury of bystanders by objects thrown by the
grinding wheel, and operators being knocked off the tractor by low hanging limbs and then being run over by
the equipment. Accidents are most likely to occur with machines that are loaned or rented to someone who
has not read the owner’s manual and is not familiar with a stump grinder.
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.)
When engaging PTO, the engine RPM should always be low. Once engaged and ready to start cutting, raise
PTO speed to 540 RPM and maintain throughout stump grinding operation.
STARTING AND STOPPING SAFETY
OPERATIONAL SAFETY
Start tractor only when properly seated in the tractor seat. Starting a tractor in gear can result in injury or death.
Do not mount or dismount the tractor while the tractor is moving. Mount or dismount the tractor only when the
tractor and all moving parts are completely stopped.
