Productivity

  • Move up to 13 percent more material per pass with the largest standard Semi-Universal blade in the size class (10.3 m3).
  • More horsepower than the previous model with a proven Cat C15 ACERT™ engine.
  • Dual Tilt blade option optimizes blade pitch for up to 10 percent more productivity.

Performance

  • Simultaneous blade response and steering performance with dedicated implement and steering pumps.
  • Cab-mounted air conditioning condenser supports better system performance, improved engine cooling and serviceability.
  • Auto Shift automatically down shifts to the most efficient gear based on load for fuel savings.

Ease of Operation

  • Updated cab, with an integrated Roll Over Protection Structure offers greater all around visibility.
  • Improved cab pressurization helps keep dust out for a cleaner operating environment.
  • Electro-hydraulic controls reduce operator effort, improve precision and response, and enable Cat Connect GRADE technologies.
  • New Liquid Crystal Display (LCD) places machine data, settings menus, grade control data and more conveniently in front of the operator.
  • LCD display is rear-camera-ready for added safety.

Cat Connect Technologies

  • Cat Slope Indicate (Standard) displays real-time machine cross-slope and fore/aft orientation on the primary monitor, helping operators work more accurately on slopes.
  • Automatically maintain established blade slope with Cat GRADE with Slope Assist (Optional). Finish jobs faster, with better surface quality and significantly less operator effort. No additional hardware required.
  • Versatile, scalable Cat AccuGrade™ (Optional) is a dealer-installed grade control system. Choice of Laser, Global Navigation Satellite System (GNSS) or Universal Total Station (UTS) so you get the right level of accuracy to match your job requirements.
  • Remote monitoring with Product Link™/VisionLink® helps you manage your fleet more effectively and profitably.
