Abstract
A working machine includes a machine body, a dozer, a boom, an arm, a working tool, a boom cylinder, and an arm cylinder. The working machine also includes an arm crowd restricting unit and a crowd restriction releasing unit. The arm crowd restricting unit imposes a restriction on a stroke of the arm cylinder in an arm crowd direction so that a swing track of a distal end portion of the working tool is spaced from the boom cylinder. The crowd restriction releasing unit releases the restriction on the stroke of the arm cylinder to enable the arm to swing to an end of a swing range in the arm crowd direction when the boom is at a swing position at which the working tool in an operating position close to a working-tool dump position is disposed in a vicinity of a blade.
