7. LINKAGE MECHANISM

[1] POSITION CONTROL

Position control is a linkage mechanism to raise or lower the implement attached to the tractor in proportion to the
movement of the position control lever.
The implement can be positioned at any height by moving the position control lever. Fine position adjustment is
also easy.
Lift
When the position control lever (1) is moved to the "LIFT" position, the lever shaft (2) rotates and press down the
cam link (4) between the fulcrum 1 (3) and link (5).
The link (5) rotates around the fulcrum 2 (8) and pushes the spool (7) by the spool drive lever (6), opening the "LIFT"
circuit.
When the lift arm (2) moves upward, feedback shaft (4) rotates and pulls the spool (3) by the spool drive lever (1).
The lift arm stops when the spool returns to the neutral position.
