counterclockwise. Fine tune the front deck lift
assembly by turning the adjuster screw until it
reaches the 3 inch (7.6 cm) height (see Figure 24).

can be utilized to gain more adjustment. The
back tips of the side blades should measure 3 1/4
inches (8.3 cm).
11. Re-measure until all four sides are the correct
height. Tighten all the nuts on the deck lift arm
assemblies.
12. Lower the discharge deflector.
13. If the four deck adjusters 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 25).

1. Front height-of-cut plate mounting bolts
2. Single point height adjustment bolt
3. Rear height-of-cut plate mounting bolt
14. To adjust the single point system, first loosen the
front and rear height-of-cut plate mounting bolts.
15. If the deck is too low, tighten the single point
adjustment bolt by rotating it clockwise. If
the deck is too high, loosen the single point
adjustment bolt by rotating it counterclockwise.
Note: Loosen or tighten the single point
adjustment bolt enough to move the height-of-cut
plate mounting bolts at least 1/3 the length of
the available travel in their slots. This will regain
some up and down adjustment on each of the

four deck links.
16. Re-tighten front and rear height-of-cut plate
mounting bolts.
