This machine is designed to meet emission standards without interrupting operation. Improved performance, reliability, durability, and versatility result in a machine that is better built to meet your needs.

Superior Fuel Efficiency

  • Up to 35% better fuel efficiency compared to previous Cat model.
  • Deep system integration of the Cat continuously variable transmission, engine, hydraulic, and cooling systems results in significantly increased performance and fuel efficiency.
  • Eliminating the torque converter allows the capability to control engine rpm and machine speed independently, resulting in efficient digging, fine control, and easy operation.
  • Lower rated engine speed reduces component wear and operating noise.
  • Power dense engine burns less fuel by providing power and torque when needed.

Achieve Greater Productivity

  • Continuously variable transmission delivers smooth, fast acceleration and speed on grade.
  • Machine maneuvering on grade is made easy with speed-hold and anti-rollback.

  • New Autodig with Auto Set Tires for consistent high bucket fill factors.
  • Application Profiles optimize machine settings for different applications at one push of a button.
  • Job Aids help operators improve and optimize their operating skills.
  • Performance Series Buckets utilize a system-based approach to balance bucket shape against the machine’s linkage, resulting in higher fill factors and better material retention when compared with other buckets of the same rated capacity.
  • Automatic engine idle shutdown system significantly reduces idle time, overall operating hours, and fuel consumption.
  • Dual ride control accumulator system enables a wide payload range and better ride quality.
  • Standard manual front differential provides additional traction when needed. Automatic front and rear locks are available as an option.
  • Optional aggregate handler configuration offers higher payload capability for loose aggregate handling.**
  • With Fusion™ Quick Coupler, buckets can be changed without leaving the cab, allowing the machine to quickly move from task to task.

**Optional configurations and equipment may vary from region to region and require conformance to Caterpillar payload policy. Consult your dealer or Caterpillar representative for details.
