2.7 Power Take Off (PTO)
This mower is designed to operate at a PTO speed of 1000 RPM. The operating speed of the mower and
tractor can be determined by the number of splines on the driveline yoke and PTO output shaft. Those
operating at 1000 RPM will have a 1-3/8" 21-spline shaft or a 1-3/4" 20 spline shaft.. Refer to the tractor
owner's manual for instructions to change PTO speeds on models that operate at more than one 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.
authorized tractor dealer can provide the over-running clutch and its installation if needed. OPS-U- 0006_F
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.
2.8 Tire Spacing
Tractor tires should be set a minimum of 60" (1.5
m) apart measured from inside of tire to inside of
tire, or maximum width possible. Refer to the
tractor Operator's Manual or consult an authorized
dealer for instructions to change tractor tire
spacing. OPS-R- 0062
