Typically the center 3-point link is adjusted so that the
upper 3-point clevis pin is straight above the lower
3-point hitch pins. This arrangement allows for
optimum ground contour following performance.

NOTE: Customer may adjust center 3-point link to
his or her preference. Lengthening center 3-point
link allows more movement while going over raised
surfaces. Shortening the link allows more movement
while crossing over ditches. Also, shortening center
link allows the cutter to be carried higher while
traveling. Never length center link to where the
cutter is carried too low.

Tailwheel Height Adjustment
Refer to Figure 3-4:
The deck slope should be adjusted so that the cutting
blades are slightly lower at the front of the cutter than at
the back. If they are not, the tailwheel must be adjusted
up or down until the deck slope is correct.

With tailwheel adjusted to the correct position,
replace 3/8" carriage bolts (#1) and whiz nuts (#2).
Draw whiz nuts up snug, do not tighten until after
rechecking deck cutting height.
