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. 53). Measure at
"A" and "B" locations (Fig. 53) from a level surface to
the cutting edge of blade tips (Fig. 54).
3. The difference between measurements "A" and "B"
should be no more than 1/4 in. (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 in. (101.6 mm) position
following the height-of-cut decal.
3. With the machine on level surface, position one blade
front-to-rear (Fig. 55). Measure at "A" and from level
surface to the cutting edge of the blade tips (Fig. 56).
4. The measurement should be 4 in. (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 Belt
Check traction drive belt for wear after every 50 hours of
operation.
1. Raise the front of the machine and hold with jack
stands. Remove lower shield.
2. Disconnect clutch wire connector from wire harness.
3. Remove PTO drive belt. Refer to Replacing the PTO
Drive Belt on page 41.
4. Remove clutch retainer from the engine deck (Fig. 57).
5. Unhook tension spring from side of frame (Fig. 57).
6. Loosen pivot bolt enough to remove traction belt from
the drive pulley and clutch.
