10. Insert blade bolt (#1) through blade (#6), dish
pan (#4), and flat washer (#2). Secure blade with a
new locknut (#3) and torque to 450 ft-lb.
11. Repeat step 10 for the other blade.
12. Replace access cover (#5).
13. If replacing dishpan (#4), nut (#7) on gearbox output
shaft should be torqued to 450 ft-lbs. minimum and
cotter pin (#8) installed with both legs bent opposite
directions around the nut.

IMPORTANT: Examine blade bolts (#1) and flat
washers (#2) 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.
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
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.
Clutch Run-In
Refer to Refer to Figure 5-2:
Clutch
Figure 5-2
1.
Using a pencil or other marker, scribe a line across the
exposed edges of the clutch plates and friction discs.
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.
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.
4.
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 disc and plate are still aligned. A clutch that
has not slipped must be disassembled to separate
the friction disc plates. See “Clutch Assembly and
Disassembly” on page 24.
5.
Tighten each of the 8 spring retainer nuts on the
clutch housing exactly 2 revolutions to restore the
clutch to the original setting pressure.
6.
The clutch should be checked during the first hour of
cutting and periodically each week. An additional set
of scribe marks can be added to check for slippage.
See Figure 5-4 on page 24 to adjust spring length.
