“LOWER” position
When the control lever is shifted to “LOWER” position, the lever which is connected to the spool moves to the left side
with the lower pin being the fulcrum, which accordingly pushed the spool to the left side establishing the “LOWER”
circuit.
Then, the oil in the hydraulic cylinder is returned to the transmission case and the lift arm is lowered. Accordingly, the
rod is pulled to the left side and rotated counterclockwise with the center of the feedback link (control lever) being the
fulcrum.
As the lower part of the feedback link is pinned to the lever, it moves to the right with the upper pin of the lever as
fulcrum, and the spool pinned to the center of the lever is gradually returned to and stops at the “NEUTRAL” position.
