MAINTENANCE
Front-to-back adjustment
To obtain the best cutting performance, the
deck should be adjusted so the front tip of the
blades are approximately 1/8" (3.2 mm) to
1/4" (6.5 mm) lower than the rear tip. If the
front tip is higher, this will create a poor
quality of cut.
1.
Check blade height with blade facing
front to rear. Measure distance “B” at the
front and rear tip of the blade.
2.
Before making any necessary
adjustments, check to make sure that the
deck is level side-to-side. See page 48.
3.
With the deck in the 4” (100 mm) cutting
position, measure the front and rear tip of
each blade while facing front to rear.
4.
To adjust loosen the jam nut on the yoke,
remove the securing ring 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.
5.
Reinstall clevis pin and recheck
dimension.
6.
Once front to back adjustment is correct,
reinstall securing rings and secure jam
nuts.
IMPORTANT INFORMATION
Deck must be leveled side-to-side, prior to
leveling front to back. If the following front
to back adjustment is required, be sure to
adjust both front and rear linkages equally
so the deck will stay level side to side.
