PTO OPERATION
CAUTION: BE SURE ALL SHIELDS AND
GUARDS ARE IN PLACE BEFORE
OPERATING THE PTO.
CAUTION: USE THE ARTICULATION LOCK
FOR STATIONARY PTO APPLICATIONS OR
TRACTOR SERVICING.
IMPORTANT: Excessive clutch slippage can
cause premature clutch failure. Do not attempt
to unplug a jammed implement by repeatedly
engaging and disengaging the PTO clutch.
A PTO is a factory- or dealer-installed option. If
your tractor does not have a factory-installed
PTO, and you desire one, see your Buhler
Versatile dealer.
The PTO is a wet disc type clutch with an
integral brake, controlled by a solenoid
operated valve. It can be operated through the
full range of engine RPM, but cannot be
engaged when the engine speed is above 1400
RPM.
NOTE: Any tractor equipped with a PTO
option must be equipped with 38°
articulation blocks (or 33° - 31° based on tire
options).
PTO Requirements
The implement PTO drive shaft must have a 45
mm (1-3/4″) diameter splined shaft (20 spline)
yoke designed for 1000 RPM. Do not use an
adapter for a smaller yoke.
CAUTION: DO NOT USE A 35 MM (1-3/8″)
PTO ADAPTOR SHAFT. THE SHAFT MAY
BREAK AND CAUSE SERIOUS PERSONAL
INJURY.
Before operating any PTO implement:
1. Lock the drawbar directly behind the PTO
shaft to eliminate any swinging action.
2. Check for proper clearance of the PTO
drivelines to the PTO shaft and 3-point hitch,
especially when turning or in rough terrain.
3. The correct distance between the drawbar
hitch pin and the PTO shaft is 508 mm (20″).
This distance is not adjustable. No drawbar
extension is necessary to operate PTO
driven implements at 1000 RPM.
NOTE: Some implement manufacturers
may require a specific drawbar to PTO
shaft distance relationship. Refer to the
implement operator’s manual.
