On Blade Nut (#3)
Locknuts can loose their ability to lock
properly once removed. Always use a new locknut
when installing blades.
Driveline Protection
The drive-train 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
The Standard Shear Bolt 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 & nuts with genuine Land
Pride part numbers only. Refer to Figure 1-3 on page 10.

Slip-Clutch Protected Drivelines
The drivetrain is protected from shock loads with a two
plate slip-clutch. The slip-clutch must be capable of
slippage during operation. Always do a
“clutch run-in”
operation at the beginning of each season and after long
periods of inactivity to remove any oxidation that may
have accumulated on the friction surfaces. Repeat
“clutch run-in”
instructions when moisture and/or
condensation seizes the inner friction plates.
!
WARNING
Clutch Run-In
Refer to Refer to Figure 5-2:
