6. Insert the height adjustment pin into the 3 inch
(7.6 cm) cutting height location.
7. Release the transport lock and allow the deck to
lower to the cutting height.
8. Raise the discharge deflector.
9. On both sides of the deck, measure from the
level surface to the front tip of the blade. The
measurement should read 3 inches (7.6 mm).
Note: In most conditions, the back blade tip
should be adjusted 1/4 inch (6.4 mm) higher than
the front.

10. Loosen the jam nuts on the top of each deck
link. Fine tune the adjuster on the front deck lift
assembly by turning it to get 3 inch (7.6 mm)
height (see Figure 27).
To increase the height, turn the adjuster clockwise;
to decrease, turn counterclockwise.

11. The back tip of the blade 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 jam 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 28).
