Three-Point Linkage; Linkage Adjustment - Shibaura ST450 Operator's Manual

THREE-POINT LINKAGE

The tractor's three-point linkage is used to attach
three-point mounted equipment which is usually
PTO operated, such as rotary mowers, tillers, flail
mowers, snow blowers, etc. The three linkage
points with Category 1 size are the two lower lift
arms (1) in Figure 2-41, and the top link (2) in
Figure 2-41.

Linkage Adjustment

The three point linkage has adjustable stabilizers
to control lateral movement of the lower lift arms.
Loosen the lock nut and turn the adjuster (2) in
Figure 2-42, to shorten or lengthen the stabilizer,
then re-tighten the lock nut.
The height of the right-hand lift arm can be
adjusted by turning the handle (1) in Figure 2-42,
on the lift rod. To adjust the height of the left-hand
lift arm re-position the attaching pin (3) in Figure
2-43, in one of the alternative holes in the lift rod.
NOTE: Cycle the three point linkage through the
entire travel and check for any interference with
rear tires. If interference is present, adjust
stabilizers as needed.
