Mower Blade Inspection/Replacement
1.
CAUTION
Mower blades may be sharp. Always wear heavy
gloves when working with mower blades.
Flip the mower deck up to the service position.
2. Inspect the mower blades to ensure the cutting
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 75-80 ft-lbs (102-108 Nm).
Mower Blade Sharpening
Blades should be sharpened and balanced by a
professional. Maintain balance, the same bevel, and
the length of sharpened surface.
