Because it provides a large shoulder reach, blade lift height, and digging depth, the GD663A facilitates various kinds of work. Bank cut pin control can be carried out easily from the operator’s compartment. By increasing the shoulder-reach (blade overhang from rear wheels an additional 815 mm) by using articulation, the shoulder of a road can be finished without traveling on the shoulder. With a minimum turning radius of 7.1 m, the machine exhibits unrivalled manoeuvrability.
