Clearing a Blocked Rotor

WARNING
Residual pressure in the hydraulic system
could cause injury through sudden movement
of the flail rotor(s) when the blockage is
released.
• Never attempt to rotate or clear blockage
from the flail rotors by hand.
• Always wear protective gloves and use a
wooden pole.
• Ensure that the wooden pole will fit in the
flail rotor and is long enough to provide
sufficient leverage to release the blockage.
1. Set the cutting-unit-drive switch to the O
position.
2. Park the machine on level ground, release the
forward or reverse travel pedals, set the throttle
control to the slow engine-speed position, and
engage the parking brake.
3. Lower the cutting units to the ground or securely
lock them in the designated transport position.
4. Shut off the engine, remove the ignition key, and
wait for the flail rotors to stop moving.
