Troubleshooting,Adjustment,&Service
WARNING
Before checking mower, shut off PTO and
engine, remove the key, and allow all moving
parts to stop.
Leveling The Mower
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
specified in Checking Tire Pressure.
SIDE-TO-SIDE LEVELING
1. With the mower installed, place the tractor on a
smooth, level surface such as a concrete floor. Turn
the front wheels straight forward.
2. Check for bent blades and replace if necessary.
3. Place the mower in mid-cut position. Arrange the
outside mower blades so that they are pointing from
side-to-side.
4. 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 5. If the difference is 1/8"
(3mm) or less, proceed to step 6.
5. Turn the Iocknut (B, Figure 39) to raise or lower that
side of the mower.
Note: The maximum the mower can be adjusted in high
cut is 3/8" to 1/2" between the frame and mower up-stop.
See Figure 39,
FRONT-TO-BACK LEVELING
6. Arrange the blades so they face front-to-back.
7. Measure the distance from the ground to the front tip
of the center blade, and from the ground to rear tips
of left-hand and right-hand blades.
44" & 50" MOWER DECKS -
Front tip of the center blade should be 1/4" (6mm)
higher than rear tips of left-hand and right-hand
blades. If not, proceed with step 8.
38" & 42" MOWER DECKS -
A front to back deck height variance of 1/8" (3mm)
and side to side variance of 1/8" (3mm) is acceptable.
If not, proceed with step 8.
8. To raise front of mower deck, tighten Iocknuts (A,
Figure 40) and against spacers (B). To lower front of
mower deck, loosen Iocknuts (A). Locknuts must be
turned evenly on both sides to keep deck level.
10. Re-check the blade measurement then tighten the
front nut (B) against the bracket to secure.
