Benefits & Features
BUILT TO PERFORM
- Cat C7 engine meets U.S. EPA Tier 3/EU Stage IIIA equivalent or Tier 2/Stage II equivalent emissions standards, depending on emission standards of specific country.
- Power Shift Countershaft Transmission matched to engine, maximizing power to the ground.
PERFORMANCE WITH LESS FUEL
- Electronic Throttle Control helps improve productivity by optimizing HP and torque to match the power demands of the application.
- Aggressive blade angles, optimized moldboard curvature and large throat clearance allows material to roll more freely along blade, increasing efficiency.
- Hydraulic demand fan automatically adjusts speed according to cooling requirements maximizing power to the ground and improving fuel efficiency.
- Engine Idle Shutdown is available to shut down engine after a set period of time, saving fuel and helping reduce emissions.
DESIGNED FOR OPERATORS
- Proportional Priority Pressure-Compensating (PPPC) provides load-sensing hydraulics with superior control, enhanced performance, and efficiency.
- Optional AutoShift Transmission improves ease of operation and maximizes productivity by automatically shifting the transmission at optimal shift points.
- Rocker and control switches are in easy reach.
- Proven conventional controls provide industry-standard control pattern and feel for precise cutting edge movement.
