Front Castor Fork Bushing Service
The castor forks have bushings pressed into the top and
bottom of the chamber and after many hours of opera-
tion, the bushings will wear. To check the bushings,
move castor fork back and forth and from side to side. If
castor spindle is loose around the bushings, bushings
are worn and must be replaced.
1. Lock transport levers, raise cutting unit to highest
position, shut the engine off and engage the parking
brake.
2. Remove front height–of–cut caps from castor forks
and slide castor wheel assembly out of castor arm tube.
