To increase the height, turn the adjuster screw clockwise; to decrease, turn counterclockwise.

11.The back tips of the side blades should measure 3 1/4 inches (8.3 cm). Fine tune rear adjusters as required.

12.Re-measure until all four sides are the correct height. Tighten all the nuts on the deck lift arm assemblies.

13.Lower discharge deflector.

14.If the four deck links do not have enough adjustment to achieve accurate cut height with the desired rake, the single point adjustment can be utilized to gain more adjustment (see Figure 32).
