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.
