  • Increase your fuel economy up to 5% with the standard ECO mode.
  • The on-demand fan reduces fuel consumption and under-hood heat for longer component life.
  • Improve productivity with the Electronic Throttle Control which matches engine power and torque to application requirements.
  • The powershift transmission and machine balanced design ensures that you get full drawbar power to the ground with the Cat C4.4 engine.
  • The hydraulic system makes the machines more precise and predictable for a consistent grade.
  • The Digital Blade Slope Meter option shows you the grade without relying on manual grade checkers.
  • Product Link™ provides location, machine hours, fuel usage, productivity, idle time, diagnostic codes, and other machine data ondemand through the VisionLink® online interface, which helps you improve jobsite efficiency with lower operating costs.
  • Choose your comfort level in the cab with standard, mechanical suspension or air suspension seat.
  • Easily adjust the control console and steering wheel.
  • The high capacity Heating, Ventilation and Air Conditioning (HVAC) system option circulates fresh air, prevents dust entry, and keeps windows from fogging.
  • Easily add a radio to the cab using the built-in mounting location option.
  • The drawbar circle moldboard stays factory tight providing precision grading pass after pass.
  • The machine structure is built for a long life. It’s designed to use several types of work tools, such as a front blade.
  • A slip clutch option protects the circle drive if the machine strikes an immovable object.
  • The front axle maximizes bearing life while also minimizing maintenance.
  • Reduce daily greasing requirements and costly repairs to your circle and pinion with the Circle Saver option.
  • See what’s behind you with the rear camera option. The dedicated display can be always on to ensure a safe workenvironment.
  • In the event of an engine stall, count on the secondary steering system option to help stop the machine safely.
