Driveline Protection

Drive components are protected from shock loads by a
friction clutch. Friction clutches should be "run-in" prior to
initial operation and after long periods of inactivity. You
may have one of two types of frictions clutches. Refer to
Figure 4-10 and Figure 4-11 to determine which friction
clutch your All-Flex mower has. Follow "Clutch Run-In"
instructions for your particular mower.
To prevent driveline and gearbox damage, repeat
"Run-In" instructions at the beginning of each season
and when moisture and/or condensation seizes the inner
friction plates.

Clutch Run-In

Clutches With 8-Alan Head Socket Bolts

Refer to Figure 4-10
1. Loosen counterclockwise all 8 Alan head socket
bolts uniformly 6 full turns.
2. Cycle clutch on and off 5 or 6 times (15 seconds on
and 15 seconds off) with the engine operating at half
throttle. Disengage driveline, shut off tractor and
remove key. Wait for all components to stop before
dismounting from tractor.
3. Tighten Alan head socket bolts fully back. Clutch is
ready for use
4. The clutch should be checked during the first hour of
cutting and periodically each week.

Clutches With 4-Tightening Nuts

Refer to Figure 4-11 (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 the spring load is low
enough that the clutch slips freely with the PTO
engaged.

3. Start the tractor and engage driveline drive for 2-3
seconds to permit slippage of the clutch surfaces.
Disengage the driveline, then re-engage a second
time for 2-3 seconds. Disengage driveline, shut off
tractor and remove key. Wait for all components to
stop before dismounting from tractor.
4. Inspect the 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
Assembly on page 28.
Refer to Figure 4-11 (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 the first hour of
cutting and periodically each week. An additional set
of scribe marks can be added to check for slippage.
