Slope Indicate

New optional grade control feature provides you slope of blade in cross slope direction and mainfall (fore/aft) direction without having to estimate.

Slope Assist

New optional grade control feature which helps you more easily achieve the desired blade mainfall and cross slope automatically.

Stable Blade

New optional blade control feature helps you obtain a finish grade with less operator effort.

Traction Control

New optional traction control feature reduces track slip and undercarriage wear for lower operating costs.

Eco Mode

New engine throttle settings reduce fuel consumption up to 25% to save you more money.

Heated and Ventilated Seat

Experience a new level of comfort in all climates with the new optional heated and ventilated air suspension seat.

Power Pitch Blade

This option lets the operator easily adjust the blade pitch to optimize productivity.


Cat® C4.4 ACERT™ diesel engine meets U.S. EPA Tier 3/EU Stage IIIA equivalent emission standards.

Heated, Seat-Mounted Controls

Heated joysticks (optional) offer even greater comfort in cold climates.


Optional grade control system enables operators to cut and fill to grade with increased accuracy, minimizing the need for traditional stakes and grade checkers. Large AccuGrade monitor is built into the machine’s dash for easy viewing during operation.


The standard sealed and lubricated track (SALT) undercarriage offers long life value in rugged conditions. Segmented sprockets are easy to replace and less expensive than replacing the complete sprocket hub.
