TRACTOR TOP LINK ADJUSTMENT
When the cutting height is set, adjust tractor top link
until mower top link attachment point (A) is aligned ver-
tically with mower hitch pin (B), Figure 7.
Adjust tractor top link so mower is level between caster
wheel and ground (dimension C), Figure 8. This will
allow the mower to follow ground contour.
The mower has three lower hitch plate attachment
points (D), Figure 7. It may be necessary to change the
mower hitch plate attachment point to obtain proper tire
clearance and/or lift height.
