CUTTING DECK SERVICE
If the mower cuts an 'uneven* swath, follow the pro¬
cedures below:
1. Slow the rider’s forward movement (shift into a
lower range) and move the ENGINE CONTROL
LEVER (8-C) toward FAST.
2.1 If the cut is uneven from side to side, check tire
pressure. The front should be 20 p.s.i. and the rear
are properly inflated at 12 p.s.i..
3. If an uneven pattern persists, roll the rider onto a
smooth, flat, level surface (such as a garage floor),
turn the ignition key (11-C) to OFF, and be sure the
BLADE lever (3-C) is in the OFF position. Check
the mower deck settings as follows:
SIDE TO SIDE LEVEL (30“, 33" & 42"): Rais© deck and
place a triangular block (such as a piece of angle iron)
under the rear (at the center) and lower the deck onto
the block.
A. Measure the clearance between the lower outside
edge of the blade and the floor (the right side and left
side). There should be 1/8" or less difference between
the two measurements.
33' MOWER
To level the deck, adjust the ECCENTRIC (located on
the front LEFT mower lift arm). Loosen the shoulder
bolt, rotate the eccentric toward UP or toward
DOWN as needed and hold in place while retighten¬
ing the shoulder bolt. Then, again measure the
distance to the floor as described in A after removing
the block.

FRONT TO REAR ADJUSTMENT: The distance the
mower deck is from the ground surface is pre-set at
an optimum level. Should the deck pitch ever need to
be "fine tuned", the adjusting nut "A" should be
screwed in or out only by a technician at yourSNAP-
PER Dealer. Timin g rod "B" maintains the levelness
^ the deck - front to rear as the deck is raised or
lowered.
(SINGLE BLADE MOWER)
To resetdeck( distance from ground surface), adjust
rear lift bracket at hanger cables. Raise deck, and
place block under center rear of deck-under lip.
Lower deck onto block to permit some slack in
cables. By relocating the same number of spacers
on each cable above the keyhole slot in each "arm"
of the lift bracket, the rear of deck will be lowered;
placing an equal number of spacers below the slot in
each "arm" raises the deck. Raise deck and remove
Remove hairpin, washer and chain from hanger pin
on each side of mower and ailow rear of deck to rest
on biock. Loosen jam nut on eyeboit and adjust
eyeboit untii chains can be reattached. Raise deck.
A. On HI-VAC mowers, measure the distance from
the front and rear lower edges of the deck to the
floor. The rear edge should be level with, or no more
than, 3/8" lower than the front edge.
B. On mowers with 26", 30", & 42" decks align one
blade tip to face the front of rider and measure the
distance from the tip to the floor. Rotate the blade
and measure the distance (from the same tip) to the
floor while the tip is facing the rear of rider. The
distance at the rear should be 1/8" to 5/8" more than
at the front.
