6.3 SHARPENING MOWER BLADE

1. Remove mower blade from unit.

Ariens recommends having mower blades sharpened

by a professional. Contact your Ariens/Gravely dealer.

Discard mower blade if (Figure 15):

• more than 1/2 in. (1.27 cm) of metal is removed.

• the air lift erosion area is eroded.

• the mower blade is bent or broken.

Do not change angle of cutting edge or round the

corner at the end of mower blade.

2. Sharpen mower blade by removing an equal

amount of material from each end of mower blade.

3. Check mower blade balance by sliding mower

blade on an unthreaded bolt. If blade is balanced, it

should remain in a horizontal position. If either end

of mower blade moves downward, sharpen the

heavy end until mower blade is balanced.

4. Install mower blade on unit.

CAUTION: DO NOT sharpen mower blade

while on unit. An unbalanced mower blade will

cause excessive vibration and eventual

damage to unit. Check mower blade balance

prior to reinstalling mower blades. NEVER

weld or straighten mower blades.
