SHARPENING MOWER BLADE

1. Remove mower blade from unit. See

“REPLACING MOWER BLADE” on

page 25.

Ariens recommends having mower blades

sharpened by a professional. Contact your

Ariens dealer.

Discard mower blade if (Figure 17):

• more than 1/2" (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. See

“REPLACING MOWER BLADE” on

page 25.

CAUTION: Mower blades are

sharp and can cut you. Wrap the

blades or wear gloves, and use

extra caution when servicing

them.

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.
