Mower Leveling
1. Position mower on a flat surface. Stop the
engine, set the parking brake, remove the key
and disconnect the spark plug wire(s) from the
spark plug(s).
2. Check tire pressure of all four (4) tires. If
needed, adjust to 13 psi (90 kPa)
3. Set anti–scalp rollers to top holes or remove
them completely for this adjustment.
4. Raise the deck to the transport position and take
all force off of the two large deck lift springs by
loosening nut in front of each spring (Fig. 49).
5. Place two 2” (51 mm) thick blocks under rear
left and right lower edge of mower. Place one
2–1/4” (57 mm) block under front center lower
edge
of mower.
Lower mower to the 2”
(51 mm) height-of-cut position (Fig. 49).

6. Loosen four (4) top chain bolts in slots. Check
the length of the rod/swivel assemblies. Distance
from outside of rear swivel to outside of front
swivel should be 19–7/8” (505 mm) (Fig. 50).
Make sure that all four swivels move freely in
holes.
7. If measurement is not 19–7/8” (505 mm) on each
side, adjust by turning nuts on either side of
front swivels.
8. Lift up on four (4) top chain attachment bolts, in
the slots, to take slack out of chains and tighten
flange lock nuts
.
(Deck is still supported by two
rear and one front blocks under mower.)
9. If bolts contact the end of slots, shorten or
lengthen rod/swivel assemblies as required, for
extra clearance, adjust each side same amount.
Note: When properly adjusted, the front
blade tip will be slightly lower than the
rear blade tip. See Checking for Bent
Blades on page 38 to measure.

10. Recheck that blocks just fit just under the mower
and that tension on all four chains is
approximately equal. Tighten chain attachment
bolts securely.
11. Measure height of cut. This can be checked with
the same procedure as Checking for Bent Blades
on page 38.
12. Install anti–scalp rollers for proper height-of-cut
and tighten securely.
