If the dimension at the front 
of the mowing deck is 1/8"-1/
4" lower than the dimension 
at the rear of the deck on 
each side of the mower, do

Links. With a wrench loosen the top inner bolt of the Deck 
Link. To adjust the side of the deck up or down turn the top 
bolt clockwise or counter clockwise a few turns. Adjust both 
front and rear Deck links as necessary. Retighten bolts.

the desired cutting height has been attained. If the dimen-
sions are not correct, repeat steps “c.” through “f.” above.
