Sharpen & Balance Mower Blades
1. Remove mower from the tractor. See Mower
Installation & Removal.
2. Blades should be sharp and free of nicks and dents.
If not, sharpen blades as described in following steps.
3. To remove blade for sharpening, use a wood block to
hold blade while removing the blade mounting cap-
screw (Figure 8).
4. Use a file to sharpen blade to fine edge. Remove all
nicks and dents in blade edge. If blade is severely
damaged, it should be replaced.
5. Balance the blade as shown in Figure 9. Center the
blade’s hole on a nail lubricated with a drop of oil. A
balanced blade will remain level.
6. Reinstall each blade with the tabs pointing up toward
deck as shown in Figure 10. Secure with a capscrew,
spring washer and hex washer (be certain the hex
washer is aligned with the hex shaft). Use a wooden
block to prevent blade rotation and torque capscrews
to 50-70 ft.lbs. (67-95 N.m.).
WARNING
For your personal safety, do not handle the sharp
mower blades with bare hands. Careless or
improper handling of blades may result in serious
injury.
WARNING
For your personal safety, blade mounting
capscrews must each be installed with a hex
washer and spring washer, then securely
tightened. Torque blade mounting capscrew to
50 - 70 ft. lbs. (67 - 95 N.m.)
