Changing the Side-to-Side
Leveling
Changing the side–to–side leveling is done by adjusting
tire pressure.
Changing the Side–to–Side Leveling with
Tire Pressure
1. Change the tire pressure on both deck and traction
unit. Do this to the corresponding side that needs
adjustment.
2. Recheck the front-to-rear pitch and side to side
leveling of the cutting unit.
Matching the Height of Cut
1. Check the tire pressure on both deck and traction unit.
2. Set the height-of-cut to the 4 inch (101.6 mm) position
following the height-of-cut decal.
3. With the machine on level surface, position one blade
front-to-rear (Fig. 78). Measure at A and from level
surface to the cutting edge of the blade tips (Fig. 78).
4. The measurement should be 4 inch (101.6 mm).

5. If it does not measure correctly, add air pressure in rear
tires to raise height–of–cut
6. If it does not measure correctly, decrease air pressure
in rear tires to lower height–of–cut.
7. Check carrier frame front–to–rear pitch.
Replacing the Mower Belt
Squealing when the belt is rotating, blades slipping when
cutting grass, frayed belt edges, burn marks and cracks are
signs of a worn deck belt. Replace the deck belt if any of
these conditions are evident.
1. Stop the engine, remove the key and disconnect the
spark plug wire(s) from the spark plug(s).
2. Remove the knobs and rubber washers holding the
carrier frame cover and remove the carrier frame
cover.
3. Remove the knobs and rubber washers holding the belt
covers to the cutting unit and remove the belt covers.
4. Remove the PTO drive belt. Refer to Replacing the
PTO Drive Belt on page 52.
5. Disconnect the idler arm spring to relieve tension on
the idler arm and idler pulley, then remove the worn
deck belt (Fig. 80).
6. Install the new deck belt around the two outside
spindle pulleys, the idler pulley, and in the lower
groove of the center spindle pulley (Fig. 80).
