Abstract
An earthmoving apparatus includes an earthmoving blade () extending in the width direction of an undercarriage, a lifting unit () configured to move the earthmoving blade () up and down, and a cover unit () covering the lifting unit (), wherein the earthmoving blade () can be moved by the lifting unit between a grounded position in which the earthmoving blade is in contact with the ground surface and a retracted position in which the earthmoving blade is held highest off the ground surface, while keeping a nearly vertical orientation with respect to the ground surface, the cover unit () includes a sub cover () extending from a location above the lifting unit () toward the earthmoving blade () and a main cover () slidable on the upper surface of the sub cover (), the main cover () is pivotally attached to the earthmoving blade () in such a manner that one end portion of the main cover is nearly in contact with the top surface of the earthmoving blade, and when the earthmoving blade () is in the grounded position, the other end portion of the main cover overlaps with the sub cover ().
