SERVICING THE MOWER BLADES

1.Blades should be sharp and free of nicks and dents. If not, sharpen blades as described in the following steps.

2.To remove blade for sharpening, use a 1” wrench on the flats of the spindle shaft while removing the blade mounting bolt with a 15/16” wrench (Figure 25).

3.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.

4.Balance the blade as shown in Figure 26. Center the blade’s hole on a nail lubricated with a drop of oil. A balanced blade will remain level.

5.Reinstall each blade with the tabs pointing up toward deck as shown in Figure 27. Secure with a bolt and flat washer and torque bolts to 70 ft.lbs. (94 N.m.).

WARNING

Mower blades are sharp. For your personal safety, do not handle mower blades with bare hands. Careless or improper handling of blades may result in serious injury. For your personal safety, blade mounting bolts must each be installed with a flat washer then securely tightened. Torque blade mounting bolts to 70 ft.lbs. (94 N.m.)
