Section 5: Maintenance & Lubrication
Blade Sharpening or Replacement
!
CAUTION
ALWAYS wear eye protection and gloves while inspecting,
removing, sharpening, and replacing mower blades.
IMPORTANT: 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 blades by grasping
the end of blade using a rag or a thick, padded glove,
while loosening and removing the blade mounting
bolt/bolts.
Refer to Figure 5-2:
NOTE: Care should be taken in order not to remove
any more material than necessary to sharpen blade.
2. Clean blade, blade washer, and mounting surface of
all debris before replacing or sharpening. Grind
cutting edge at the same bevel as the original.
Sharpen only the top of the cutting edge to maintain
sharpness.

Refer to Figure 5-3:
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 when sharpening.
