  • Achieve longer component life with increased size of upper hitch pin, frame plate, and bearing.
  • Optimized axle mounting results in increased structural integrity.
  • Heavy-duty steering cylinder mounts efficiently transmit steering loads into the frame.
  • Robust structures withstand the toughest conditions and multiple
  • life cycles to improve your bottom line.
  • Resilient, durable blades are designed with excellent dozing and rolling characteristics.
MOVE MORE WITH LESS FUEL
  • The Cat C7.1 engine is designed for maximum fuel efficiency and increased power density.
  • New variable displacement load-sensing implement and steering pumps deliver on-demand hydraulic flow, resulting in improved fuel efficiency.
