An improved single-stage torque converter sends 75% of engine torque through a converter and 25% through a direct drive shaft for greater driveline efficiency and higher torque multiplication. The torque divider provides improved efficiency and a broader range of performance in second gear dozing and scraper push loading.

Provides the operator instant feedback on the condition of operating systems and records performance data to help diagnose problems. Gauges monitor fuel level and the temperature of the engine coolant, hydraulic oil, and power train oil. Includes alert indicators that monitor engine oil pressure, coolant flow, electrical system and transmission oil filter.

The elevated sprocket and fully suspended undercarriage work together, increasing traction while creating a smoother ride for your operators. The elevated sprocket design transfers implement shock loads to the mainframe, so final drives, axles and steering components are isolated from harsh impacts. These benefits translate into higher production and longer component life.
  • Bogie Suspension allows the track to conform to ground condition, providing up to 15% more ground contact, especially in hard, uneven terrain. Higher traction means less slippage, better balance, and a smoother ride.
  • Roller frames are tubular to resist bending and twisting, with added reinforcement where operating loads are highest.
  • The undercarriage idler guard provides additional wear protection from abrasive material to the moving undercarriage. Includes rubber idler protectors.

All blades feature a strong box-section design that resists twisting and cracking. Blades are made of high tensile strength steel that stands up to the most demanding applications.
  • High-Capacity Universal Blade – Efficient at moving big loads over long distances.
  • Semi-Universal Blade – Built for tough applications in tightly packed material where penetration is important.
  • Optional Dual Tilt – Allows the operator to optimize the blade pitch angle.
  • Cutting Edges and End Bits – Cutting edges are DH-2™ steel. End bits are DH-3™ to provide maximum service life in tough materials. For extremely severe applications, moldboard wear plates, extended wear life end bits and cutting edges are available.
  • Cat Work Tools offer a range of special application blades, including coal stockpile blade, cushion dozer blade, reclamation blades and wood chip blade.
