Featuring all new Advanced Productivity Electronic Control Strategy (APECS) transmission controls provides greater momentum on grades and fuel savings by carrying that momentum through the shift points.
The Cat C7.1 engine is designed for maximum fuel efficiency and increased power density. Two engine options are available to meet the emission standards for Tier 4/Stage IV or Brazil MAR-1 and China Nonroad Stage III, equivalent to Tier 3/Stage IIIA.
Your operators can work more efficiently and stay comfortable with our customer-inspired cab features.
Enter and exit the cab easily and safely with a new fold up STIC armrest.
We are constantly introducing features on our machines in an effort to enhance safety for the operator.
Integrated electronics provide flexible levels of information to both the site and the operator. This integration creates a smart machine and more informed operator, maximizing the productivity of both.
The straight blade (2.8 m3/3.7 yd3) is designed for production dozing in stockpile material and general earthmoving.
The coal blade (10.6 m3/13.8 yd3) is designed for precise and productive dozing while helping to retain load control with increased capacity for lighter materials. Wing angles help retain the load while dozing. This blade is available from Cat Work Tool and Services (CWTS).
