Rockshaft and 3-Point Hitch

Positioning Center Link

–UN–11DEC05
A—Upper Hole
B—Middle Hole
C—Lower Hole
The draft sensing rockshaft center link attaching bracket
has holes which allow three different positions for
attaching the center link. The position effects the draft
sensing sensitivity.
Standard position is (C).
Move the center link attachment to holes (B) if:
•
Excessive hitch activity or hunting occurs in draft control
operation.
•
The rear of the implement raises too much when lifted.
The implement weight which can be lifted is reduced
slightly with the center link attachment in the lower
holes.
•
The draft control lever range is too small.
Move the center link attachment to holes (C) if:
•
The hitch seems unresponsive in draft control operation
and allows the engine speed to drop too far before
raising the rockshaft.
•
The rear of the implement droops and drags the ground
as the implement is lifted.
Upper hole (A) eliminates nearly all draft sensing.
NOTE: Implements with Category II mast height 610 mm
(24 in.) will use the upper two holes.
