Section 4: Maintenance & Lubrication
Refer to Figure 4-2:
IMPORTANT: Examine blade bolts (#1) and
washers (#5) for excessive wear and replace if worn.
IMPORTANT: Locknuts can loose their ability to
lock properly once removed. Always use a used
blade nut or plain nut in steps 8 & 9 below and then
replace used nut with new locknut in step 10.
8. Start by assembling blades without shim (#2). Insert
blade bolt (#1) through blade (#3), dish pan (#4) and
flat washer (#5). Temporary secure blade with a used
1 1/8"-12 nut. Draw nut up snug. Do not tighten.
9. Check blade deflection. If deflection is greater than
3/4", remove blade bolt and reassemble as before
except include shim (#2) in the assembly. Select
shim thickness based on deflection. The greater the
deflection, the thicker the shim.
10. Once blade deflection is correct, replace used nut
with new locknut (#6) and torque to 450 ft-lbs.
11. If replacing dishpan (#4), nut on gearbox output shaft
should be torqued to 450 ft-lbs. minimum and cotter
pin installed with legs securely bent around nut.

Slip-Clutch Protected Drivelines
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.
Clutch Run-In
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 friction
surfaces. To prevent driveline and gear box damage,
repeat "run-in" instructions at beginning of each season
and when moisture and/or condensation seizes inner
friction plates.
!
WARNING
Engage parking brake, disengage PTO, shut off tractor, and
remove key before dismounting tractor to make adjustments.
Refer to Figure 4-3:
1. Using a pencil or other marker, scribe a line across the
exposed edges of the clutch plates and friction discs.
