Regular Maintenance
SERVICING THE MOWER BLADES
Service Interval: Every 100 Hours or As Required
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 22).
4. Use a file to sharpen blade to a fine edge. Remove
all nicks and dents in the blade edge. If the blade is
severely damaged, it must be replaced.
5. Balance the blade as shown in Figure 23. 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 24. 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 45-55 ft.lbs. (61-75 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
