Abstract
PURPOSE: To improve efficiency of operation of front loader, by employing an arrangement capable of rapidly turning the bucket for releasing or unloading the bucket through shifting of a selector switch or by changing the control lever turning speed.
CONSTITUTION: At the time of turning the bucket for unloading the same, protruding speed of piston 10a is lowered, so that bucket turning speed is also lowered. In order to overcome the above situation, control lever 16 is shifted to release position P after turning on selector switch 21. Thereupon, control lever 16 comes out of engagement with a control member of interlocking switch 22, so that it is turned ON and solenoid 20a is energized. As the result, pressure liquid supplied from pump 14 to the front side of piston 10a via tilt control valve 15 is applied to a liquid circuit through which pressure on the back side of piston 10a is acted to the front side of piston 10a via selector valve 20, so that protruding speed of piston 10a can be increased.
