Friction clutches must be capable of slippage during
operation to protect gearboxes, drivelines, and other
drive train parts. Friction clutches should be “run-in” prior
to initial operation and after periods of inactivity to
remove any oxidation from the friction surfaces. Repeat
“run-in” at the beginning of each season and when
moisture seizes the inner friction plates.
Refer to Figure 5-4 to determine which friction clutch
your cutter has. Follow “run-in” instructions for your
specific clutch type.

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.
Make sure the area is clear of all bystanders and
machine is safe to operate.
4.
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.
