Blade Sharpening or Replacement
WARNING
!
To avoid serious injury or death:
Always wear eye protection and gloves while inspecting,
removing, sharpening, and replacing mower blades.
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:
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. See
Figure 5-2. 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.

IMPORTANT: Replace mower blades with genuine
Land Pride blades only.
NOTE: Care should be taken in order not to remove
any more material than necessary to sharpen blade.
