Maintenance

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 30).

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 31).

15. To adjust the single point system, first loosen the front and rear height-of-cut plate mounting bolts.

16. 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.

17. Re-tighten front and rear height-of-cut plate mounting bolts.

Important: Torque the front and rear height-of-cut plate mounting bolts to 27-33 ft-lb (37-45 N-m).

18. Repeat steps 9 through 13.
