Important
There are two different sizes and shapes of
blades. The shorter blade goes into the center spindle. The
two longer blades go on the outside spindles (Fig. 32). See
figure 31 for the shape difference.

1. Hold the blade end using a rag or thickly padded glove.
2. Install the thick washer, blade, thin flat washer, and the
nut (Fig. 28).
Important
The sail (curved part of the blade) must be
pointing up toward the inside of the mower to ensure
proper cutting.
3. Tighten the nut to 80 to 100 ft.-lb. (109 to 136 N

m).
Greasing the Blade Spindles
Grease the mower after every 25 operating hours or once a
year, whichever occurs first. Grease more frequently when
operating conditions are extremely dusty or sandy.
Grease Type: General-purpose grease.
How to Grease
1. Disengage the PTO, set the parking brake, lower the
attachment lift, stop the engine, and remove the ignition
key.
2. Clean the grease fittings (Fig. 33) with a rag.

3. Scrape any paint off the end of the fittings.
4. Connect a grease gun to each fitting (Fig. 33).
5. Pump grease into the fittings.
6. Wipe up any excess grease.
Checking PTO Drive Belt
Tension
Check the PTO drive belt tension after 5 hours of operating
with a new belt, then every 50 hours or once a year,
whichever occurs first.
1. Check the tension indicators on the front of the pulley
box. If the tension indicators do not line up, release the
belt tension and turn the adjustment knob. Push the belt
tension release arm back toward the pulley box to
tension the belt (Fig. 34).
