Blades & Bushes
The cutting blades are mounted in hardened bushes and are free-swinging to reduce
shock load and damage to the transmission.
Blades and blade bushes should be inspected for wear/damage the intervals stated in
the maintenance schedule.
Replace blades that are bent, excessively nicked, damaged, or when they are worn
beyond the shape of their original profile. Always replace blades immediately when
their level of wear or damage causes rotor vibration; continued use of the machine in
this condition could cause damage to the gearbox and/or drive components. Blades
must always be replaced in opposing pairs to retain rotor balance.
Replace bushes and blade fixings immediately should excessive signs of wear or
damage be detected.
Ensure that the machine is safely supported using suitable lifting and support
equipment before attempting to work beneath a machine
– never use or rely on
the tractor’s hydraulic system to support the machine.
