Attitude control device for front loader

Abstract

Abstract PURPOSE:To eliminate the need for using a solenoid valve for controlling a boom and an operating tool, and thereby simplifying the operation when horizontal ground contact of the operating tool is controlled. CONSTITUTION:A control lever 14 can separately or simultaneously operate operating tools such as a bucket, etc., rotatably pivoted on a boom and the head of the boom, and the oscillating lever 14 is spring-energized to a neutral position. Only when the boom is operated to be lowered and the operating tool performs shovelling, the lever 14 is engaged with an engaging body 81, and an automatic return of the lever is restricted. When it is detected that a boom position is at a transport-position, and that the operating tool is at a position where it can horizontally contact the ground, the engagement of the lever 14 with the engaging body 81 is released. The horizontal ground contact of the operating tool can thus be controlled without using any solenoid valve.
