DECK LEVELING ADJUSTMENT

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 and
Front-To-Back Leveling Adjustment procedures, in order,
as follows.
1. Park the mower on a smooth, level surface such as a
concrete floor. Turn the deck caster wheels straight
forward.
2. Check for bent blades and replace if necessary.
3. See Figure 13. Measure the distance between the
ends of the roller bar and the ground. If there is more
or less than 1/2" (12mm) distance between the roller
and ground, adjust the chain anchors (A) until the
required distance is achieved.
4. Disengage the PTO. Place the mower in mid-cut
position. Arrange one of the mower blades so that it
is pointing from side-to-side.
5. Measure the distance between the outside tips of
each blade and the ground. If there is more than 1/8"
(3mm) difference between the measurements on
each side, proceed to step 6. If the difference is 1/8"
(3mm) or less, proceed to step 7.
6. See Figure 13. Loosen the outside nut (B). Turn the
eccentric nut (C) to raise or lower the side of mower.
When mower is level, hold the eccentric nut while
tightening the outside nut.
7. Arrange the blades so they face front-to-back.
8. Measure the distance from the ground to front tip and
rear tip of the left and right-hand blades. Blades
should be level. If not, proceed with steps 9 - 11.
9. See Figure 14. To raise front of mower deck, loosen
front nut (A) and turn rear nut (B) against bracket (C).
10. To lower front of mower deck, loosen rear nut (B) and
away from bracket (C) to lengthen rod.
11. Re-check measurement before tightening front nut
(A) against bracket.
