OPERATION

TWR-180 / TWR-120 12/04

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.
