Mower operating power is supplied from tractor PTO. Refer to your tractor manual for PTO engagement and
disengagement instructions. Always operate the tractor PTO in the 540 rpm speed selection. DO NOT OVER
SPEED! Know how to stop tractor and mower quickly in case of an emergency.
All tractors that are not equipped with a “live” takeoff (PTO) need to be equipped with an over-running PTO
clutch type driveline. See page 23.
NOTE: 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.
Most accidents occur because of neglect or carelessness. Keep all helpers and bystanders at least several
hundred feet from an operating rotary mower. Only properly trained people should operate this machine.
When this machine is operated in populated areas or in other areas where thrown objects could injure persons
or property, standard equipment safety chain shielding (which is designed to reduce the possibility of thrown
objects) must be installed. If this machine is not equipped with full chain shielding, operation must be
stopped when anyone comes within several hundred feet.
The majority of accidents involve entanglement on the driveline, injury of bystanders by objects thrown by the
rotating blades, and operators being knocked off the tractor by low hanging limbs and then being run over by
the mower. 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 rotary mower.
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 cutting operation.
