Measure height,from levelsurface, of leftand rightbladetips
at outside edge of deck. Ifblades are equal or not more than
1/8 inch different, no side to side adjustment is necessary.
If adjustment is necessary, loosen right side eccentric mount-
ing screw (FIG. 6-ADJ) and turn eccentric clockwise or
counterclockwise as required to level mower deck. NOTE:
When groove in eccentricis pointing downward, right side of
deck is in lowest position. When groove is pointing upward,
right side of deck is in highest position.

eccentric mounting screw securely.
MOWER DECK LEVEUNG ADJUSTMENT
Before making any mower deck leveling adjustments, check
air pressure in all four tires. Recommended air pressure is t 0
to 14 pounds per square inch. Check sidewall of tires for
manufacturer's maximum tire pressure. Do not exceed this
pressure. Equal tire pressure should be maintained in all tires.
Tractor main frame should be level across the front from left
side to right side. ff main frame will not sit level, the two outside
axle mounting screws may be too tight. The two outside
mounting screws must be loose enough to allow front axle to
pivot. NOTE: DO NOT loosen center mounting screw.
The mower deck level can be adjusted from front to back and
from side to side. Always adjust front to back levelfirst.
1. Park tractor on firm level surface, such as a driveway or
garage ficor.
2. Checkandadjustheightof mowerdeckasoutlined inMower
Deck HeightAdjustment paragraph.
3. Place mower deck cutting height adjustment lever/pedal in
mid cut position. NOTE: All adjustments will be made from
mid cut position.
To adjust front to back level.
4. Measure height, from level surface, of right side blade tips at
front and rear of mower deck (be sure all tires are
properly inflated). If distances are equal or not more than 1/
8 inch lower in front, no front to back adjustment is neces-
sary.
5. If adjustment is necessary, loosenfront eccentric mounting
screws (FIG. 5-ADJ) and turn front adjustment eccentric
clockwise or counterclockwise as required. NOTE: When
groove on eccentric is pointed straight forward (FIG. 5-ADJ
inset) front of deck is at the lowest point. Turn both eccentrics
so grooves are pointing same direction (upward or down-
ward). Always keep grooves toward front of lawn tractor.
If more adjustment is necessary, front of mower deck may be
raised or lowered by relocating eccentric mounting screws in
higher or lower hole position on mower deck mounting bracket.
6. Hold eccentric with a wrench while tightening eccentric
mounting screws securely.
BLADE DRIVE BELT ADJUSTMENT

full speed while mowing, the blade drive belt should be tight-
ened.

belt retainer location and replace in same location after
making adjustment.

Only a small amount of movement should be required.
4. Re-tighten hax nut on idler pulley.
