Driveline Protection
!
WARNING
To avoid serious injury or death:
26708
•
Always follow "Tractor Shutdown Procedure" provided in
this manual before dismounting the tractor.
•
A slip clutch that has been in use or has slipped for as little
as only two or three seconds during run-in may be too hot
to touch. Allow a hot clutch to cool before working on it.
The drivetrain is protected from shock loads with a shear
bolt or a slip clutch depending on which option the cutter
is set-up with.
Shearbolt Protected Drivelines
!
WARNING
To avoid serious injury or death:
Do not operate cutter with snap ring missing on the gearbox
input shaft. Should the shearbolt shear, the snap ring will
prevent the driveline from slipping off the shaft.
The standard shearbolt driveline is secured to the cutter
with a shearbolt for protection of driveline and gearbox.
The shearbolt is designed to shear off when the blade
impacts objects that the cutter is not designed to cut
through. Replace shearbolt with Land Pride part #802-
264C. Refer to Figure 1-4 on page 15.
Slip-Clutch Protected Drivelines
The drive-train is protected from shock loads with a two
plate slip-clutch. The slip-clutch must be capable of
slippage during operation. The slip-clutch driveline is
secured to the cutter with a grade 8 bolt.
Blade Bolt
Access Cover
The clutch 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 "clutch run-in" instructions at the beginning of
each season and when moisture and/or condensation

seizes the inner friction plates.
