Replacing the bearing unit
Special instructions
for HC/HCH
Blades
Follow the method described for replacing V-belts, but do the following
after removing the belts:
Remove the bearing unit without detaching the pulley by loosening
the 4 bolts that fix the bearing unit to the rotor guard, and pulling the
bearing unit out of the bottom of the mower.
On HC/HCH mowers, the V-belt pulley must be detached before the
bearing unit can be removed.
The blades are made of boron-alloyed steel, drop-forged and hardened,
so they can cope with the loads and shocks that are expected to occur
during operation. The hardness of the blades is controlled constantly
and all blades are stamped with GMR followed by the spare part
number.
WARNING
Using blades made by other manufacturers risks fatal
injury.
The machine warranty will be void if they are used.
WARNING
Before sharpening the blades on Triplex side mowers,
the side mower must first be secured as shown in the
illustration below. Failure to do so means there is a
risk of personal injury.
