Versatility

  • Excellent machine balance, power-to-weight-ratio and VPAT blade for general dozing and fine grading.
  • For dozing productivity, updated SU configuration follows the design of larger Cat dozers with front-mounted lift cylinders to provide more breakout force and stability.
  • Forestry and landfill arrangements offer added features and guarding to take on especially harsh environments.

Ease of Operation

  • Updated cab, with an integrated Roll Over Protection Structure (ROPS) and 15° offset seat, offers greater all around visibility.
  • Improved cab pressurization helps keep dust out for a cleaner operating environment.
  • New Liquid Crystal Display (LCD)* places machine data, settings menus and more conveniently in front of the operator.
  • Low effort electro-hydraulic controls* offer precise response and facilitate GRADE technologies.
  • Choose the best speed for your job: 5-speed mode is easily adjusted with throttle dial.
  • Bi-directional control to preselect forward/reverse gears – automatically downshifts to the most efficient gear based on load for reduced operator effort and improved efficiency.
*Not available on SU configuration.

Performance

  • Cat 7.1 ACERT™ electronic engine provides more power and up to 3 percent better fuel efficiency compared to the previous model.
  • New, more robust engine fuel system features high efficiency fuel filters and water-in-fuel sensors for greater fuel system reliability.
  • Differential steering with dedicated steering pump maintain power in turns, even with a full blade load.

Cat Connect Technology

  • Cat Stable Blade (Standard) complements the operator’s blade-control input for attaining finish grades quicker with less effort.
  • Cat Slope Indicate (Standard)* displays machine cross-slope and fore/aft orientation on the primary monitor, helping operators work more accurately on slopes.
  • Automatically maintain established blade mainfall/cross slope with Cat GRADE with Slope Assist™ (Standard)*. 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.
  • Factory equip your dozer for easy installation of an AccuGrade system with the AccuGrade Ready Option (ARO) (Optional).
  • Manage your fleet more effectively and profitably with Product Link™/VisionLink® remote monitoring.
*Not available on SU configuration.
