Regular Maintenance
Servicing The 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 38).
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 39. 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 40. Secure with a capscrew
(D, Figure 40), spring washer (C), and spline washer
(B). Be certain the spline washer is aligned with the
shaft splines. Use a wood block to prevent blade
rotation and torque capscrews to 45-55 ft.lbs. (61-75
N.m.).
