7. POSITION CONTROL LINKAGE
Position control is a mechanism to raise or lower the
implement attached to the tractor in proportion to the
movement of the control lever.
The implement can be positioned at any height by
moving the position control lever. Fine position
adjustment is also easy.
■ Lift
1. When the position control lever is moved to the LIFT
position, the control arm shaft (2) rotates to the arrow.
Therefore, the spool drive lever (3) moves around the
fulcrum P and push the spool (1) opening the LIFT
circuit.
2. When the lift arm moves upward, the feedback lever
shaft (4) is rotated to the arrow, since the feedback
rod is actuated. Therefore, the spool drive lever (3)
moves around the fulcrum Q and pull the spool (1).
3. The lift arm stops when the spool returns to the
neutral position.
■ Down
1. When the position control lever is moved to the
DOWN position, the control arm shaft (2) rotates to
the arrow. Therefore, the spool drive lever (3) moves
around the fulcrum P and pull the spool (4) opening
the DOWN circuit.
2. When the lift arm moves downward, the feedback
lever shaft (4) is rotated to the arrow, since the
feedback rod is actuated. Therefore, the spool drive
lever (3) moves around the fulcrum Q and pushes the
spool (1).
3. The lift arm stops when the spool (1) returns to the
neutral position.
