W Blade sharpening
CAUTION: Always wear heavy gloves to protect your hands when working
with the cutter blade.
1. Remove the cutter deck (see page 34 thru. 36), and turn it upside down.
2. Remove the blade bolts and the blade.
CAUTION: To avoid damaging the blade, be sure to hold it securely while
dressing or resharpening it.
3. Maintain the original cutting edge bevel when resharpening or dressing the
blade. Leave a l/64 inch (0.4mm) flat face on the cutting edge; a razor-
sharp edge will chip easily, and will become dull quickly.
l/64 in IO.4 mm)
4. When resharpening, do not file the blade parallel to the original edge.
Instead, file the blade on an angle as shown, and do not extend the cutting
edge any farther toward the center of the blade. Be sure to remove equal
amounts of material from each end of the blade to maintain proper balance.

5. After sharpening, test the blade’s balance using a screwdriver as shown. If
either side dips slightly below horizontal, file that side. Replace the blade if
it dips excessively.
CAUTION: An unbalanced blade will cause abnormal vibration, and eventual
mower damage.
