Slip-Clutch Protected Drivelines
!
WARNING
Always disengage PTO, engage parking brake, shut off
tractor, remove ignition key, and wait for all moving parts to
come to a complete stop before dismounting tractor to make
adjustments.
Cutter drive components are protected from shock loads
by either a two plate friction clutch or a shear bolt. The
shearbolt is designed to shear off when the blade
impacts objects that the cutter is not designed to cut
through. Avoid shear bolt failure by engaging the PTO
slowly at low engine rpm. See your Land Pride Dealer
when replacing shear bolts.
Clutch Run-In
The clutch must be capable of slippage during operation
to protect gearbox, driveline and other drive train parts.
Friction clutches should be “Run-in” prior to initial
operation and after long periods of inactivity. To protect
driveline and gearbox, repeat “Run-In” instructions at the
beginning of each season and when moisture and/or
condensation seizes the inner friction plates.
IMPORTANT: Examine blade bolts (#1) and
washers (#4) for excessive wear and replace if worn.
IMPORTANT: Locknuts can loose their ability to lock
properly once removed. Always use a new locknut
when installing blades.
