6. Loosen the 4 top chain bolts in the slots. Check the
length of the rod/swivel assemblies. The distance from
the outside of the rear swivel to the outside of the front
swivel should be 19-17/32 inches (496 mm) (Fig. 61).
Make sure that all four swivels move freely in the holes.

7. If the measurement is not 19-17/32 inches (496 mm) on
each side, adjust by turning the nuts on either side of the
front swivels.
8. Lift up on the 4 top chain attachment bolts, in the slots,
to take the slack out of the chains and tighten the flange
locknuts. (The deck is still supported by two rear and
one front blocks under the mower.)
9. If the bolts contact the end of the slots, shorten or
lengthen the rod/swivel assemblies as required for extra
clearance. Adjust each side the same amount.
Note: When properly adjusted, the front blade tip will be
slightly lower than the rear blade tip; refer to Checking for
Bent Blades, page 28, to measure.
10. Recheck that the blocks just fit just under the mower
and that the tension on all four chains is approximately
equal. Tighten the chain attachment bolts securely.
11. Measure the height of cut. This can be checked with the
same procedure as Checking for Bent Blades, page 28.
12. Install the anti-scalp rollers for proper height-of-cut and
tighten them securely.
13. Raise the deck lift lever to the transport position
(Fig. 60).
14. Adjust the compression springs by turning the front
spring nuts so that the distance between the two large
washers is 11 inches (279 mm) (Fig. 61). Clockwise
will shorten the spring; counterclockwise will lengthen
the spring.
Note: Make sure that all hardware is tight.
Cleaning Under the Deck
Remove grass buildup under the deck daily.
1. Position the 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. Raise the deck to the transport position.
3. Raise the front of the machine by using the Z Stand;
refer to Using the Z Stand, page 24.
Unit could fall onto someone and cause serious
injury or death.
•
Use extreme caution when operating unit on
Z Stand.
•
Use only for cleaning deck and removing blades.
•
Do not keep unit on Z Stand for extended
periods of time.
•
Always shut engine off and set parking brake
before performing any maintenance to deck.
Warning
Belt Inspection
Inspect all belts every 100 hours.
Check belts for cracks, frayed edges, burn marks, or any
other damage. Replace damaged belts.
Replacing the Deck Belt
Squealing when the belt is rotating, blades slipping when
cutting grass, frayed belt edges, burn marks, and cracks are
signs of a worn deck belt. Replace the deck belt if any of
these conditions are evident.
