Blade Sharpening or Replacement
WARNING
!
To prevent serious injury or death:
•
Always wear eye protection and gloves while inspecting,
removing, sharpening, and replacing mower blades.
•
Replace mower blades in pairs with genuine Land Pride
blades only. Not replacing both blades will result in an out-
of-balance condition.
1. If the blade cutting edge is dull or nicked, it should be
replaced or sharpened. Remove a blade by grasping
one end of the blade with a rag or thick, padded glove
while loosening and removing the blade bolt.
2. Clean blades and mounting surfaces of all debris
before sharpening or replacing the blades.
3.
Refer to Figure 5-2:
Grind cutting edge at the same bevel as the original.
Sharpen only the top side of the cutting edge.
4. Refer to Figure 5-3:
Check blade balance by positioning the blade
horizontally on a nail or shaft through the center hole.
If either end of the blade rotates downward, grind
(remove) metal on that end until the blade will
balance. The blade is properly balanced when
neither end drops. Balance of a blade is generally
maintained by removing an equal amount of material
from each end of the blade.
IMPORTANT: Out-of-balance blades will contribute
to bearing damage and structural cracks in the
mower housing.
NOTE: Care should be taken in order not to remove
any more material than necessary to sharpen blade.

taken while installing the blade bolt to make sure it
does not get cross threaded.
3. Torque the blade bolt to the specified torque value.
