ABSTRACT:
A backhoe elevator includes a front, loading arm supported on a frame forward of a driver cab midway between front and rear axles. The frame includes two spaced apart elongated members that define a space for retraction of the arm between the members. The controls for the loading arm are disposed along a central axis of the backhoe elevator. The engine is transversely mounted and includes two outputs, one for a hydraulic pump and one for a gear box that is below the support for the loading arm between the frame members. The support for the loading arm may include two parallel plates, one of which is a vertical extension of one of the elongated members and the other of which is mounted on an upper plate that is between and perpendicular to the elongated members. One of the elongated members may have a rear portion that is curved outwardly so that it is not parallel to the other of the elongated members.
