3.7 Power Take Off (PTO)
Only operate the mower on a tractor equipped to operate at 540 RPM PTO speed. Tractors operating at 540
rpm will have a 1-3/8” diameter 6-spline PTO shaft stub. Refer to the tractor operator’s manual for operating
the PTO at the proper speed
If operating an older model tractor where the tractor’s transmission and PTO utilize one master clutch, an
over-running clutch must be used between the PTO output shaft and the driveline of the mower. Consult an
authorized tractor dealer to purchase and install an over-running clutch if needed.
4. GETTING ON AND OFF THE TRACTOR
Before getting onto the tractor, the operator must read and completely understand the mower and tractor
operator manuals. If any part of either manual is not completely understood, consult an authorized dealer for a
complete explanation.
4.1 Boarding the Tractor
Use both hands and equipped handrails and steps for support when getting on the tractor. Never use tractor
control levers for support when mounting. Always seat yourself in the operator’s seat and fasten the seatbelt.
Only operate the tractor and mower with the ROPS in the raised position.
Never allow passengers to ride on the tractor or mower. Riders can easily fall off and be seriously injured or
killed from being ran over by the tractor and mower. It is the operator’s responsibility to forbid extra riders at all
times.
DO NOT use a PTO adapter to attach a non-matching Implement driveline to a Tractor
PTO. Use of an adapter can double the operating speed of the Implement resulting in
excessive vibration, thrown objects, and blade and implement failure. Adapter use will also
change the working length of the driveline exposing unshielded driveline areas. Serious
bodily injury and/or equipment failure can result from using a PTO adapter. Consult an
authorized dealer for assistance if the Implement driveline does not match the Tractor PTO.
(S3PT-14)
Never operate the Tractor and Mower if the Implement input driveline is directly connected
to the Tractor transmission. Tractor braking distances can be substantially increased by
the momentum of the rotating Mower blades driving the Tractor transmission even though
the Tractor clutch has been disengaged. Install an over running clutch between the Tractor
PTO and the Mower driveline to prevent this potentially dangerous situation.
(S3PT-16)
Do not mount or dismount the Tractor while the tractor is moving. Mount
the Tractor only when the Tractor and all moving parts are completely
stopped.
