Improved Hydraulic Efficiency

New implement and steering variable displacement load sensing piston pumps.
Hydraulic flow now on demand, for improved fuel efficiency.

Cat C7.1 Engine

The Cat C7.1 engine is designed for maximum fuel efficiency and increased power density.

Features innovative Cat electronics, fuel injection process, air-management systems and aftertreatment solution (for Tier 4 Final) with Cat Selective Catalytic Reduction.
Innovative systems effectively lower the average working engine speed and reduce overall system heat loads for improved performance and fuel efficiency.
Deep system integration amongst engine and emissions system, power train, hydraulic and cooling system result in lower fuel consumption on average compared to the previous model.

Cat Planetary Powershift Transmission

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.

Robust Structures

Your bottom line is improved by highly durable structures that achieve multiple life cycles and withstand the toughest conditions.

Full box-section rear frame resists torsional shock and twisting forces.
Heavy-duty steering cylinder mounts efficiently transmit steering loads into the frame.
Axle mounting has been optimized for increased structural integrity.
Upper hitch pin, frame plate, and bearing size have been increased for longer life.

Robust Structures Design

Push beams are through-width, not merely attached to side of frame.
In corner dozing, stresses are transferred and absorbed through a larger portion of the frame.
