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 21).
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.
