Checking the Deck
Side-to-Side Leveling
1. Check the tire pressure on both deck and traction unit.
2. Position the blades side-to-side (Fig. 79). Measure at A
and B locations (Fig. 79) from a level surface to the
cutting edge of blade tips (Fig. 80).
3. The difference between measurements A and B should
be no more than 1/4 inch (6 mm).

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. 81). Measure at A and from level
surface to the cutting edge of the blade tips (Fig. 81).
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. Disengage the PTO and set the parking brake.
2. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
3. Remove the knobs holding the carrier frame cover and
remove the carrier frame cover.
4. Remove the knobs holding the belt covers to the
cutting unit and remove the belt covers.
