g. Verify proper throttle adjustment by check-
ing RPM readings as outlined above.
C. Deck Corner Ball Wheel Roller Settings
1. Matching the set heights of the ball rollers on
the four corners of the mower deck to the
desired cut height will prevent edge scalping
and minimize any side-to-side variance in cut
height.
2. There are five height adjustment holes in the
bracket that mount the ball rollers to the deck.
a. Use the top set of holes for cut heights of
1-1/2 inches or lower.
b. Use the middle set of holes for a 2-1/2 - 3-1/2
inch cut height.
c. Use the bottom set of holes for cut heights of
4 inches or higher.
D. Deck Center Anti-Scalp Roller
1. The front roller helps prevent the scalping of
high spots and uneven terrain across the cen-
ter section of the deck.
2. The roller on the front of the deck is fixed at
the factory and can not be adjusted.
E. Lap Bar Adjustment
1. Proper lap bar and seat adjustment will result
in the following:
a. In the neutral position with hands on the
lap bars,
1. Operator’s upper arms should be relaxed
and approximately vertical.
2. Operator’s forearms should be approxi-
mately horizontal.
b. In the full forward position,
1. Operator’s back should stay in contact
with the seat back.
2. Lap bars should not contact operator’s
legs.
c. In the full reverse position,
1. Lap bars should not contact the opera-
tor’s legs or torso.
2. Set the seat to the preferred operating position.
a. Adjustment lever is located under the front
edge of the seat.
b. The seat has five inches of front-to-rear
adjustment available.
4. Check factory settings of lap bars for the con-
ditions listed above.
Note:
If lap bar adjustments are required,
height adjustments should be made prior to
angular adjustments.
5. To adjust the height of the lap bars,
a. Remove the nuts from the lap bar mounting
bolts (see Fig. 11 ).
b. Remove the bolts and lap bar and reposi-
tion to the second set of holes in the mount-
ing block.
c. Replace the bolts and nuts, and tighten to
28-34 ft-lbs.
1. If angular adjustments are also required,
nuts can be tightened until snug at this
point.
d. The same adjustments should be made to
both sides of the mower.
6. To adjust the front-to-rear angle of the lap bars,
a. Loosen the nuts on the lap bar mounting
bolts, leaving the bottom one fairly snug.
b. The top hole is slotted, allowing the lap bar
to pivot on the bottom bolt.
c. Move lap bar to the desired angle and
tighten the nuts to 28-34 ft-lbs.
Note:
In the neutral position, the handles of
the lap bars should be aligned with approxi-
mately a one inch gap between the tips. Widen
the gap by adding shim washers to the top
mounting bolt between the lap bar and the
mounting block.
d. Check the results of any adjustments to
the conditions described in section a,
above. Repeat any adjustment procedures
as required until all conditions are met.
F.Deck leveling Procedure
1. Park the mower on a flat paved surface, engage
the parking brake, shut off the engine, remove
the key from the ignition switch, disconnect the
spark plug wires and using the transport lever,
position the mowing deck into the 4" height of
cut (top) position. (The 4" height of cut position
is recommended in order for one to see and
obtain a measurement. Any height of cut posi-
tion is acceptable as long as a proper measure-
ment can be taken.)
2. Check the right and left front tire pressure.
Adjust as necessary to 20-25 psi. Tire pressure
can affect blade height by as much as a 1/4”.
