SERVICE AND ADJUSTMENT
FRONT-TO-BACKADJUSTMENT
(See Fig. 13).
IMPORTANT:
DECK MUST
BE LEVELED
SIDE-TO-SIDE,
PRIOR TO LEVELING
FRONT
TO REAR. IF THE FOLLOWING
FRONT
TO
BACKADJUSTMENT
IS REQUIRED,
BE SURE
TOAD JUST BOTH FRONTAND
REAR
LINKAGES
EQUALLY SO THE DECK WILL
STAY LEVEL SIDE TO SIDE.
To obtain the best cutting
performance,
the deck
should
be adjusted
so the front tip of the blades
are approximately
1/8" to 1/4" lower than the rear
tip. If the front tip is higher, this will create a poor
quality of cut.
Check
blade height with blade facing front to
rear. Measure
distance
"B" at the front and rear
tip of the blade.
Before making
any necessary
adjustments,
check to make sure that
the deck is level side-to-side.
With the deck in the 4" cutting position,
measure
the front and rear tip of each
blade while facing front to rear.
To adjust loosen the jam nut on the yoke,
remove the hairpin and push the clevis
pin out while supporting
the deck. To
lower that specific
corner, lengthen
the
rod assembly
by turning
the yoke counter
clockwise.
To raise that specific
corner,
shorten
the rod assembly
by turning
the
yoke clockwise.
Reinstall
clevis pin and recheck
dimension.
Once front to back adjustment
is correct,
reinstall
hairpins
and secure jam nuts.
