SERVICING THE MOWER BLADES

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.
Service Interval: Every 100 Hours or As Required
NOTE: Replace blades and bolts in sets.
1. Remove mower from the tractor. See Mower
Installation & Removal.
2. Blades should be sharp and free of nicks and dents.
If worn or damaged, replace the blades as described
in following steps.
3. To remove the blade, use a wood block to hold blade
while removing the blade mounting capscrew (Figure
22).
4. Install the new blades with the lift tabs pointing up
toward deck (Figure 24). Secure with a capscrew (E,
Figure 23), spring washer (D), spline washer (C), and
alignment pin (B) (be certain the spline washer is
aligned with the shaft). Use a wooden block to pre-
vent blade rotation and torque capscrews to 45-55
ft.lbs. (61-75 N.m.).
WARNING
For your personal safety, blade mounting
capscrews must each be installed with a spline
washer and spring washer, then securely
tightened. Torque blade mounting capscrew to
45 - 55 ft. lbs. (61 - 75 N.m.)
5. Check that the mower blades are timed perpendicular
to each other (see Figure 24). If not, remove the
blade and rotate the adapter (A, Figure 23).
