ION
Do not connect the PTO driveline to the tractor or operate the implement unless the
implement is securely connected to the tractor.
2.7 Power Take Off (PTO)
This mower is designed to operate at a PTO speed of 540. 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 6-spline shaft and those operating at 1000 RPM will have a 21-spline shaft.
Note:
Only the 284
mower can be ordered to operate on tractors equipped with a 1000 RPM 21-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. An authorized
tractor dealer can provide the over-running clutch and its installation if needed.
OPS-R- 0066_A
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)
2.8 Tire Spacing
Tractor tires should be set a minimum of 60”(1.5
mm) 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.
