Balancing the Mower Blades
CAUTION
Thrown objects hazard
An unbalanced mower blade can create excessive vibration
and damage the unit, or cause mower blade failure resulting
in thrown debris.
Be sure blade is balanced before installing.
1. Clean the blade to remove any dried grass or other
debris.
2. Clamp a nail in a bench vise, hang the blade on the nail,
and position the blade in a level horizontal position as
shown in Figure 29.

3. Check the balance of the blade. If either end of the blade
moves downward the end that moves downward is
heavier than the other. Sharpen the heavy end until
balance is achieved. See Sharpening the Mower Blades
for sharpening instructions.
4. Repeat the process until the mower blade remains in the
horizontal, level position.
Installing Mower Blades
1. Reinstall each blade with the airlifts (A, Figure 30)
pointing up towards the mower deck as shown. Install
the concave side of the washer (B) towards the blade.
Install the blade mounting bolt (C) hand tight to hold the
washer and blade onto the shaft (make sure the blade is
fully seated onto the shaft).

2. Tighten the blade mounting bolt to 50 - 60 ft. lbs. (68 - 81
