BLADE MAINTENANCE

CAUTION: Before removing the

blades, be sure the engine has

stopped and the key has been

removed. The blades may be

sharp. Wear gloves or wrap them

in a towel before handling them.

Inspect the blades daily for straightness,

sharpness, and balance. Replace the blades

if they are cracked, worn, bent or out of

balance.

NOTE: Keep blades sharp. Mowing with dull

blades will cause poor cut performance. It will

also put additional strain on the engine by

slowing the mower cutting speed.

CAUTION: Never try to straighten

a blade which has been bent or

try to weld a blade that is cracked.

Always replace with a new blade

to ensure safety.

To sharpen the blades, remove the blades by

inserting a block of wood and turning the

blade bolt counter clockwise (see figure 29).

Stop Block

Figure 29

CAUTION: Always wear safety

eye protection when sharpening

the blades.

Be sure to wear a thick glove or wrap the

blade in a towel to protect your hands from

being cut. Insert the blades in a vise and use

a mill file or grinder. File the blade along the

original angle until the blade tip is at a 30 °

angle again.

IMPORTANT: When sharpening blades, be

sure to grind the same amount on each side.

Unbalanced blades will cause excessive

vibration and could cause the spindles to

wear prematurely.

Check the blade balance by inserting a

horizontal rod through the center hole of the

blade. The heavy side of the blade will drop

down. Sharpen the heavy side of the blade

until the blade is balanced, see figure 31.

After sharpening, install the blades back onto

the mower deck. Make sure the wings are

facing up. Reinstall the blade bolt and

Iockwasher.
