Catterpillar is the world`s leading manufacturer and exporter of construction and mining equipment, diesel and natural gas engines and industrial gas turbines. Catterpillar offers 776d off-highway tractor. Cat off-highway tractors have a yoke-type hitch that oscillates four ways to reduce frame stresses. Rugged turn stops prevent excessive wagon rotation in either direction. The rear platform functions as a power train guard and provides a safe, stable work area. Fenders and mud flaps protect from material thrown by tires.
