The dozer features a fully automatic four-speed transmission that offers optimal fuel and dozing efficiency.  At 197kW (265hp) and an operating weight of 29,776kg (65,644lbs), the new D7 dozer replaces the D7E model.

The D7 is claimed to move up to 8% more material per hour than the D7E, with about 6% more weight and 12% more horsepower. Blade capacity is increased by 10%, and the elevated sprocket undercarriage delivers better ride and balance, as well as increased penetration force.

Other features of the D7 include Slope Indicate, which is standard with the premium display package, and shows machine main fall and cross-slope for easy reference. ARO with Assist is a grade-ready option bundled with basic blade control and a new set of assist features that work in the background to help operators get more done in less time.

The AutoCarry feature automates blade lift to help maintain consistent blade load and help reduce track slip.

Like the D6 and D8T, the new D7 is driven by a fully automatic four-speed transmission, which continuously adjusts for maximum efficiency and power to the ground without added operator input. Cat says the cab has been completely redesigned and offers operators more space, multiple seat and control adjustments for optimal comfort and an easy-to-use 254mm (10”) touchscreen operator interface.
