RUBBER DISK REPLACEMENT
The flexible coupler side drive is designed to flex when striking heavy objects
or during start-up to protect gearboxes. The rubber disks will wear out over
time and require replacement much like slip clutch disks. To maximize rubber
disk life, lower tractor engine speed to an idle when engaging the PTO and
avoid striking the ground with cutter blades.

Slip Clutch Assembly
Periodically inspect the disks for signs of cracking. A disk may run for some
time after a crack starts but this is the first sign that disk replacement is
required in the future.
To replace the disks, remove hardware items (6, 7, 8 or 9 and 10). Remove
sleeves (7) from old disk and install in new disk. Reassemble and torque bolts
to 115 N-m (85 lbs-ft). See Figure 15. Take special care not to rotate gearbox
shaft and throw blades out of time. If rubber disks have failed and blades are
hitting, you will need to re-time the blades per instructions on page 26.
