Periodically inspect the blade adapter(s) for cracks, especially if you strike a foreign
object. Replace them when necessary.
Follow The Steps Below for Blades Service:
1. The Cutting Deck on the mower
should not be removed. To access
the Blade(s), the mower can be
placed on a lift, driven on ramps, or
placed on jack stands.
Be sure the mower is
secure, and the Parking Brake Handle is
set when removing the Blade(s).
2. Remove the Hex Nut and the Elastic
Saucer which holds the Blade and
the Blade Adapter to the Cutting
Deck Motor.
3. Remove Blade and Blade Adapter
from the Cutting Deck Motor’s
spindle.
4. Balance the Blade on a screwdriver’s round shaft handle to check its balance.
Remove metal from the heaviest side until it balances evenly. When sharpening
the Blade, follow the original angle of the Blade and its cutting edge. Grind or file
each cutting edge equally to keep the Blade balanced.
An unbalanced blade will cause excessive vibration when rotating at high
speeds. It may cause damage to the motor or the mounting hardware which could cause
personal injury.
5. Visually inspect the Blade Adapter for any damage or cracks.
6. Lubricate the inner surface of the Blade Adapter with a light oil.
7. Slide the Blade Adapter onto the Deck Motor’s Spindle. Place the Blade on the
Blade Adapter so that the side of the Blade marked BOTTTOM or with the PART
NUMBER faces the ground. When the mower is in the operating position, make
sure that the Blade is aligned and seated on the Blade Adapters Flanges.
8. Place the Elastic Saucer Washer onto the Blade. Replace the Hex Nut and tighten
to a torque of 48 Nm minimum, 52 Nm maximum.
To ensure safe operation of your mower, periodically check the
blade nut(s) for correct torque.
