Abstract

A construction machine is capable of returning the posture of an earth removal plate (blade) from a rocking posture to a predetermined normal posture. A stay is mounted on the construction machine body to move in upward and downward directions. The earth removal plate is mounted on the distal end portion of the stay, and is rockably movable in forward and rearward directions by an angle cylinder controlled by a flow of hydraulic fluid in response to receiving an instruction about rocking the earth removal plate. A normalization switch gives an instruction to set the posture of the earth removal plate to a predetermined normal posture from the rocking posture. The posture of the earth removal plate is set to the predetermined normal posture from the rocking posture in response to the instruction from the normalization switch.
