Therefore, when the boom is rotated diagonally forward and the boom is rotated downward, a sufficient gap can be secured between the boom cylinder at the base of the boom and the upper edge of the earth removal plate. Therefore, there is no possibility that the boom cylinder will come into contact with the upper edge of the earth removal plate during the excavation work when the boom is turned. Moreover, the necessary height for the earth removal plate can be secured at the central portion of the earth removal plate, and excavation workability can be improved without reducing the function of the earth removal plate.
