[. . . ] If you remember that the front right blade tip adjustment is fixed and you level to that height, adjusting the decks will be simplified. Once the deck is level one may find that the height of cut does not match the height of cut indicator. A final adjustment may be made by lowering or raising the height of cut link accordingly. To raise the deck: remove the shoulder bolt mounting the height of cut link to the lift handle and reassemble the shoulder bolt in the lowest of the three holes. To lower the deck: remove the shoulder bolts mounting the height of cut link, flip the height of cut link around and reassemble the shoulder bolts in the top of the set of three holes and the bottom hole.
