FEATURES
PERFORMANCE
Programmable Autoshift option simplifies operation by allowing transmission to be programmed to shift at optimal points to match application.
Power Shift Countershaft Transmission matches to engine, maximizing power to the ground.
Electronic Throttle Control helps improve productivity by providing best match of horsepower and torque for application demands.
EFFICIENCY
Aggressive blade angle, optimized moldboard curvature and large throat clearance allow material to roll more freely along blade, increasing efficiency.
Hydraulic demand fan automatically adjusts speed according to cooling requirements resulting in more power to the ground and improved fuel efficiency.
Engine idle shutdown is available to shut down engine after a set period of time saving fuel and helping reduce emissions.
EASE OF OPERATION
Selectable blade lift modes - Fine, Normal, or Coarse - allow you to choose the blade lift modulation mode that best fits your application in operating styles
Joystick controls with electronically adjustable control pods reduce hand and arm movement by 78%, helping reduce operator fatigue.
Left joystick controls steering, articulation, return-to-center, wheel lean, gear selection, left moldboard lift cylinder and float.
Right joystick controls drawbar, circle and moldboard functions as well as electronic throttle control and manual differential lock/unlock.
Articulation Return-to-Center automatically returns machine to a straight frame position from any angle with the touch of a button.
Convenient access from the top of the circle to the patented top-adjust wear strips and inserts make them easy to add or replace.
Shimless Moldboard Retention System uses vertical and horizontal adjusting screws to keep moldboard wear strips aligned for reduced blade chatter and precise blade control
COMFORT
Control pods can be adjusted electronically, making it easy to set to ideal operating position.
Standard Cat Comfort Series suspension seat is fully adjustable.
High capacity Heating, Ventilation, and Air Conditioning (HVAC) system dehumidifies and pressurizes cab, sealing out dust, and helps keep windows clear.
TECHNOLOGY
Shuttle Shift allows smooth, fast direction shifts without requiring you to manipulate the throttle or inching pedal.
Cat Product Link™ aids your equipment management with remote monitoring capabilities.
