Mower Blade Inspection/Replacement

Mower blades may be sharp. Always wear heavy
gloves when working with mower blades.
1. Rotate the mower deck up to the service position.

edges are sharp. If blades are dull or damaged,
they must be removed and sharpened or replaced.
3. Place a short piece of 2 x 4 wood between the end
of the blade and an appropriate structural part of
the deck frame to prevent the blade from rotating.
4. Loosen the blade bolt counterclockwise and
remove the blade for sharpening or replacement.
5. When installing a blade, the wood block must be
placed on the opposite side of the blade to prevent
blade rotation when tightening the blade bolt.
6. Torque the blade bolt to 100 ft-lbs (136 Nm).

Mower Blade Sharpening

Blades should be sharpened and balanced by a pro-
fessional. Maintain balance, same bevel, and length
