"Up", "Neutral", "
The main control valve has four positions, ``down'' and ``float.'' The oil discharged from the pilot pump is received into the pilot pressure control valve, and the main control valve has four positions: ``up'' and ``down'' by operating the control lever.
When the main control valve is switched to either position, the oil discharged from the pilot pump is supplied to a separate pilot control valve, and a switch button provided on one side of the valve is turned on, the main control valve is "floated". 1. A "floating" position release device, characterized in that, in a hydraulic circuit configured to switch to a position, a circuit communicating with a pressure circuit when the pilot pressure control valve is activated is connected to the other side of the pilot control valve.
