SHARPENING MOWER BLADE
1. Remove mower blade from unit (see REPLACING
MOWER BLADE on page 16).
Gravely recommends having mower blades sharpened by a
professional. Contact your Gravely dealer.
Discard mower blade if (figure 15):
• more than 1/2 in. (1.27 cm) of metal is removed.
• the air lift erosion area is eroded.
• the mower blade is bent or broken.
Do not change angle of cutting edge or round the corner at
the end of mower blade.
2. Sharpen mower blade by removing an equal amount of
material from each end of mower blade.
3. Check mower blade balance by sliding mower blade on
an unthreaded bolt. If blade is balanced, it should
remain in a horizontal position. If either end of mower
blade moves downward, sharpen the heavy end until
mower blade is balanced.
4. Install mower blade on unit (see REPLACING MOWER
BLADE on page 16).
