6. Adjust the front eyebolts until the chains are tight and
the deck is still resting on the 2 x 4’s. Tighten jam
nuts. See Figure 47.
7. Loosen the nuts and allow the rear of the deck to
rest on the 2 x 4’s and 1/4” spacers. Slide the chains
down in the slots until the chains are tight and tight-
en the nuts. See Figure 47.
8. Remove all 2 x 4 blocks and spacers from under the
mower deck.
9. With the deck height adjustments complete and cut-
ting height still set at 4", adjust the deck lift spring to
a compressed length of 12" (30,5cm). Be sure to
measure the spring only. Adjust the length of the
deck lift spring by tightening or loosening the (2) 5/8”
hex nuts that are closest to the spacer at the front
end of the spring (see Figure 47). After adjustment
is made, tighten these two nuts together. Perform
this step to both springs.
