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. 57). Measure at A
and B locations (Fig. 57) from a level surface to the
cutting edge of blade tips (Fig. 58).
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 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. 59). Measure at A and from level
surface to the cutting edge of the blade tips (Fig. 60).
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 Traction Drive
Belt
Service Interval/Specification
Check all belts after every 50 operating hours or monthly,
whichever occurs first. Look for cracks, wear, and signs of
overheating.
1. Remove the top capscrew securing idler support and
idler bracket to rear frame (Fig. 61).
2. Loosen bottom two mounting screws enough to allow
belt to pass between drive pulley and idler support
(Fig. 61).
3. Raise the wheel off the ground, to allow the belt to be
removed, and remove the belt.
