Drivelines With Slip Clutches
!
CAUTION!
Engage parking brake, disengage PTO, shut off tractor, and
remove key before working on or around the driveline and/or
slip clutch.
!
CAUTION!
Slip clutches that have been in use or have been slipped for only
two or three seconds during run-in may be too hot to touch.
Allow a hot clutch to cool before working on it.
Cutter drive components are protected from shock loads
by a friction slip clutch. The clutch must be capable of
slippage during operation to protect the gearbox,
driveline and other drive train parts.
Friction clutches should be “run-in” prior to initial
operation and after long periods of inactivity to remove
any oxidation that may have accumulated on the friction
surfaces. Repeat “run-in” instructions at the beginning of
3/4" maximum

2.
Carefully loosen each of the 8 spring retainer nuts by
exactly 2 revolutions. It will be necessary to hold hex
end of retainer bolt in order to count the exact
number of revolutions.
3.
Make sure the area is clear of all bystanders and
machine is safe to operate.
4.
Start tractor and engage PTO drive for 2-3 seconds
to permit slippage of the clutch surfaces. Disengage
PTO, then re-engage a second time for 2-3 seconds.
Disengage PTO, shut off tractor and remove key.
Wait for all components to stop before dismounting
from tractor.
5.
Inspect clutch and ensure that the scribed markings
made on the clutch plates have changed position.
Slippage has not occurred if any two marks on the
friction disk and plate are still aligned. A clutch that
has not slipped must be disassembled to separate
the friction disk plates. See “Clutch Disassembly,
Inspection & Assembly” below.
