Float Position
If the lock plates are rotated to the vertical position,
3, the lower links, 4, will be allowed to float up and
down by 40 mm (1-1/2″). This will allow an implement
vertical movement independent of the tractor.

TOP LINK
The top link, 1, is adjusted by turning the sleeve, 2,
after raising the handle/locking latch, 3. To prevent
further rotation of the sleeve, push the handle/latch
down to engage in either of the two slots in the end
of the top link assembly.
Most equipment will operate at the proper height
when the link is adjusted to 724 mm (28.5″)
measured between the center of the attaching
points. Readjust to level the equipment as required.
When not in use, the top link can be removed and
stored, or left in a vertical position and retained by the
transport hanger, 3, Figure 143.
