stop before leaving operator’s position. Never
adjust, lubricate, clean or unplug machine with
the engine running. Failure to comply could

The slip clutch on the mower-conditioner is part of the
secondary PTO drive shaft, and is mounted on the
input shaft of the bevel gearbox. It is set to slip in the
event an overload occurs during machine operation.
Prior to the start of each season and after long
periods of nonuse, the slip clutch should be
burnished to ensure it is not locked up.
To burnish the slip clutch:
1. Ensure the tractor is shut off, if connected to unit.
Open the shielding over the slip clutch. Loosen
the eight cap screws, 1, 1/2 turn.
2. Attach a tractor to the disc mower-conditioner as
outlined in the “General Information” section of
this manual, if not already connected.
3. Operate the tractor at 1/3 throttle, and engage
the tractor PTO for several seconds, or until the
slip clutch visibly smokes, at which time,
disengage the tractor PTO. Turn the tractor off.
If the clutch does not slip, the clutch must be
disassembled to unlock the friction discs.
Consult your authorized dealer for slip clutch
service.
4. After slipping the clutch, retighten the eight cap
screws 1/2 turn at a time until the space band, 2,
contacts the clutch housing, 3. Then back off
each nut 1/4 turn.

the slip clutch setting or damage to the machine
could result.
