Sharpening the Mower Blade

WARNING

Avoid injury! Mower blades are sharp.

•Always wear gloves when handling mower blades or working near blades.

•Always wear safety eye protection when grinding.

1.Sharpen the mower blades with grinder, hand file, or electric blade sharpener.

2.Sharpen the mower blade by removing an equal amount of material from each end of the mower blade.

3.Keep the original bevel (A, Figure 29) when grinding. DO NOT change the mower blade bevel.

4.The mower blade should have a maximum 1/64” (0,40 mm) cutting edge (B) or less.

5.Balance the mower blades before installing.

Balancing the Mower Blades

WARNING

Avoid injury! Keep mower blades balanced.

An unbalanced mower blade can create excessive vibration and damage the unit or cause mower blade failure.

1.Clean the mower blade to remove any dried grass or other debris.

2.See Figure 30. Put the mower blade on a nail in a vise and turn the mower blade to the horizontal position.

3.Check the balance of the mower blade. If either end of the mower blade moves downward, sharpen the heavy end until the mower blade is balanced. See Sharpening the Mower Blades for proper sharpening instructions.

4.Repeat the process until the mower blade remains in the horizontal position.

Reinstalling the Mower Blades

1.Wedge a wooden block between the mower blade and the mower deck housing to keep the mower blade from turning.

2.Reinstall each mower blade with the air lifts pointing up towards the mower deck as shown in Figure 31. Secure with the mower blade mounting bolt and flat washer (A & B, Figure 31) and torque to 70 ft. lbs (94 Nm).
