If a foreign object gets caught in the machine:
Before carrying out any maintenance or repairs on the machine, switch off the tractor
engine, remove ignition key, wait until all moving parts have come to a standstill and
apply park brake.
Remove foreign body.
Check that no working parts have been damaged.
Engage the tractor PTO.
The cam type cut-out clutch re-engages automatically.

frequency). This could cause premature wear of the cut-out clutch due to friction
between the cams and their housings.
