BUILT TO LAST

  • Caterpillar designed power train components work as a system for reliability and performance.
  • Durable, proven Cat 3-speed mechanical planetary power shift transmission.
  • Heavy structures make for a robust machine that can stand up to high impact shock loads and twisting forces.
  • Caterpillar elevated sprocket undercarriage protects the power train from shock loads.
  • Suspended undercarriage provides a smooth ride and better traction in uneven terrain.

HARD WORKING

  • Harness more power to the ground with a proven, Caterpillar exclusive torque divider.
  • Differential Steering maintains full power to both tracks for best-in-class turning, even with a full blade load.
  • High drive design allows heavy components to sit low in the mainframe, resulting in a low center of gravity and excellent machine balance.
  • Dedicated implement pump ensures hydraulic power when you need it.
  • Proven Advanced Modular Cooling System (AMOCS) offers cooling capacity and air flow so you can work in the most demanding environments.

OPERATOR PRODUCTIVITY

  • Choice of cab or canopy dozer, with Integrated Roll Over Protective Structure (ROPS/FOPS), for comfort, excellent visibility and added safety.
  • Simple tiller bar control for direction and gear selection offers easy operation and precise control in close areas.
  • Quiet cab interior, pressurized to help keep out dust for a cleaner operating environment.
  • Easy-to-read analog display with machine health monitoring keeps operator informed about machine operating conditions.
  • Added comfort with available cab air conditioning.
  • Choose from three light packages, all with longer life, brighter LED bulbs to illuminate your work area.

UNDERCARRIAGE DURABILITY

  • Choose Heavy Duty undercarriage for aggressive, high-impact applications like logging/reforestation, side slopes and rocky conditions.
  • General Duty undercarriage is available for low-to-moderate impact applications.
  • General Duty and Heavy Duty components are interchangeable and Heavy Duty shoes can be installed on General Duty link assemblies to maximize flexibility to meet your needs.

EQUIPPED FOR THE JOB

  • Semi-Universal (SU) blade gives you the capacity you need for a wide variety of earthmoving jobs.
  • Add an optional Rock Guard and Wear Plate to the blade for added durability and longer wear life.
  • Rear attachment choices add versatility - choose single-shank ripper, rigid drawbar, rear counterweights or a dealer-installed winch.
  • A fixed ripper provides a simplified, lower cost option.
  • Choose a single-shank ripper with pin puller to enable shank position changes from the cab.

DESERT/HIGH ABRASION

  • Equip your dozer with factory features designed to enhance machine performance in extremely sandy or abrasive underfoot conditions.
  • Cooling system is designed for high debris environments, with easy access for cleanout.
  • Specially coated fan and radiator help resist abrasion.
  • Core protection grid.
  • High ambient fluids package.
  • Sealed bottom guard and added seals to help keep fine abrasive particles out of components.
  • Optional wear plates can be replaced to give you longer blade life when working in abrasive conditions.

COLD WEATHER CAPABLE

  • For work in extreme cold, choose factory options for added starting capability and improved component performance in arctic temperatures.
  • Cold weather batteries provide added cranking power.
  • Arctic undercarriage and carrier rollers have cold weather seals for added protection.
  • Arctic lubricant provides a thinner oil for better lubrication in extreme conditions.
