MOWER ADJUSTMENTS
If the cut is uneven, the mower may need leveling.
Unequal or improper tire pressure may also cause an
uneven cut. Make sure tire pressure is correct as speci-
fied in Checking Tire Pressure. To achieve proper mower
levelling, perform Side-To-Side Leveling, Front-To-Back
Leveling and Transport Height Adjustment procedures, in
order, as follows.
Side-To-Side Leveling
1. With the mower installed, place the rider on a
smooth, level surface such as a concrete floor. Turn
the front wheels straight forward.
2. Check for bent blades or deck and replace if neces-
sary.
3. Use the Dial-A-Cut TM Control to place the mower in
mid-cut position by aligning front edge of mower lift
lever with number 2 or 3 on show scale. Make sure
mower lift lever is in down position.
4. Loosen nut (C, Figure 11) so trailing arms are loose.
Mower must be resting on rollers with no weight on
trailing arms.
5. Make sure rear rollers (C, Figure 9) are on the
ground. If not, refer to Transport Height Adjustment.
NOTE: If rollers do not rest on the ground, perform
transport height adjustment. Note that it will be nec-
essary to perform transport height adjustment again
after all leveling procedures are completed.
Position blade(s) side-to-side and measure distance
form outside tip of blade(s) to ground. Measurement
should be equal (within 1/8”).
6. See Figure 9. On left side of mower, make sure
eccentric nut is in correct starting position as shown.
Loosen outside nut (A) and rotate eccentric nut (B) so
that flat side with hole closest to it is towards the rear.
Tighten outside nut (A) while holding eccentric nut
(B).
7. On right side of mower, loosen outside nut (A). Turn
eccentric nut (B) counterclockwise to raise side of
mower, or clockwise to lower right hand side of
mower.
NOTE: Do not turn eccentric nut more than 1/4 turn in
either direction. When adjusted beyond 1/4 turn, nut will
move mower in opposite direction than when starting
adjustment.
8. When adjustment is correct, hold eccentric nut (B)
and tighten nut (A) to 30 ft. lbs. Check measurement
on both sides of mower.
