engine and remove the key.
10. Mower unit
10-1. Use of both sides of knife
Both sides of the knife are sharpened. When one side is worn, remove the pair of
knives, and attach them reversely. The knife is attached to the knife shaft mounting
hitch section by 11 mounting pin 32 and the nut with disc washer, and the knife can
be removed easily.
Attach the mounting pin in the same direction as before.
The knife shaft assy is balanced when shipped from our factory; therefore, unless
all the knifes of the same weight each are replaced at one time, or unless replaced
symmetrically on the right and left portions of the knife shaft, the weight balance
may be lost and vibration may be generated.
Since the hammer knife shaft assy are rotated at high speed, pay attention to the
weight balance when replacing the hammer knife.
10-2. Replacement of knife
When both sides of the knife are worn, grind each blade in a manner that the
weight of each knife will be the same as much as possible.
When the weight balance of the knife shaft assy including the knife blades is poor,
the knife shaft assy will generate vibration, breaking the machine.
10-3. Grinding the knife
Wear protective goggles and gloves when grinding the knife.

CAUTION
When the balance is lost, the knife shaft assy will vibrate because it is rotating at high
speed, which is very dangerous. Exercise care sufficiently.
