Clutches With 4 Adjusting Nuts
Clutch Run-In
Refer to Figure 4-4 (View - A):
1. Using a pencil or other marker, scribe a line across the
exposed edges of the clutch plates and friction disks.
2. Tighten all 4 nuts uniformly until spring load is low
enough that the clutch slips freely with power take-off
engaged.

3. Start tractor and engage power take-off for 2-3
seconds to permit slippage of clutch surfaces.
Disengage power take-off, then re-engage a second
time for 2-3 seconds. Disengage power take-off, 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 disk and plate are still aligned. A clutch that
has not slipped must be disassembled to separate
the friction disk plates. See Clutch Disassembly &
Assembly on page 22.
Refer to Figure 4-4 (View - B):
5. Turn all 4 nuts fully back if no two marks on the
friction disk and plate are still aligned. Clutch is ready
for use.
6. The clutch should be checked during first hour of
cutting and periodically each week. An additional set
of scribe marks can be added to check for slippage.
Clutch Disassembly & Assembly
If clutch run-in procedure indicates that one or more of the
friction disks did not slip, then the clutch must be
disassembled to separate the friction disks.
