LEVELING THE MOWER DECK
These adjustments should be made on a level surface
with the tires inflated to the correct air pressure.
The mower is leveled from side to side with the slots
where 4 chains fasten to the mower mounting brackets.
The mower is leveled from front to rear by adjusting the
rod running down each side of the frame (Figure 16).
1. Raise mower deck and insert 3" (7.6 cm) tall blocks
to support deck.
2. Lower deck onto blocks so chains are slack.
3. Measure from bottom of mower blade end to
ground.
4. Shut off engine. Engage parking brake. Remove
the ignition key.
5. Set hydraulic lift cylinder so cut of height reads the
same as blade height measurement.
6. Loosen the locknuts on the side where the chains
are slack and slide the bolt down the slot until the
chain is tight.
7. Tighten bolt and nuts in mower mounting brackets.
8. Lift mower and remove blocks.
9. Measure height of deck at each side.
Measurements must be within 1/16" (1.5 mm) of
each other.
10.If measurements are out of range, fix by adjusting
chains on low side of deck.
11.Once deck is level side to side, measure height of
deck at middle of front and on both sides of rear.
Front of deck should be 1/8" (3 mm) lower than
rear.
12.To adjust, loosen rear hex nut of the front mower lift
pivot on each rod.
13.Turn the front hex nut on each rod until mower is
1/8" (3 mm) lower in front.
NOTE: If mower cannot be leveled, it may be neces-
sary to loosen the rear nut of the rear mower lift pivot to
get more threads at the front of rod for adjustment.
After loosening rear nut and adjusting level, tighten
front nut on rear mower lift pivot.
14.Tighten rear hex nut on each rod that was
loosened in step 11.
