Never operate the Tractor and Mower if the Mower main 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 engaged. Install an over running clutch between the Tractor PTO
and the Mower driveline to prevent this potentially dangerous situation.
WARNING!
2.7 Power Take Off (PTO)
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. An authorized tractor
dealer can provide the over-running clutch and its installation if needed.
Depending on the unit, the mower is designed to operate at a PTO speed of 540 or 1000 RPM. Most tractors
operate at either 540, or a combination of 540 and 1000 RPM PTO speeds. 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 540 RPM will have a 1-3/8” diameter 6-spline shaft and 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.
WARNING!
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 Mower resulting in excessive
vibration, thrown objects, and blade and mower 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.

2.8 Tire Spacing
Tractor tires should be set a minimum of 60” apart
measured from inside of tire to inside of tire. Refer to
the tractor Operator’s Manual or consult an authorized
dealer for instructions to change tractor tire spacing.
