Maintenance
4. 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
5. To adjust the single point system, first loosen the
front and rear height of cut plate mounting bolts.
Fine tune the rear adjusters as required; the single
point adjustment can be utilized to gain more
adjustment.
1. Adjuster link
2. Jam nut
6. 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.
Loosen the front and rear height of cut plate
mounting bolts. Fine tune the rear adjusters
as required; the single point adjustment can be
utilized to gain more adjustment.
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.

Adjusting the Wing Decks
1. Measure from the level surface to the front tip
of the LH wing deck blade. The measurement
should read 4 inches (102 mm).
2. Measure from the level surface to the front tip
of the RH wing deck blade. The measurement
should read 4 inches (102 mm).
Note: As with the center deck, in most
conditions the back tips on the wing blades
should be adjusted 1/4 inch (6.4 mm) higher than
the front.
3. The left and right wing decks have blade height
adjustments with front and rear adjust points. To
adjust the wing blade height, first loosen the front
and rear height of cut hanger mounting nuts.
There are four locations — two on each side of
the channel (see Figure 51).
