New High Drive Cat D7 dozer

The new Stage 5 Cat D7 dozer offers high drive undercarriage design, increased performance and a broadest choice of technology features to help customers get the most from the bulldozer. A fully automatic 4-speed transmission offers optimal fuel and dozing efficiency, plus ease of operation.  At 265hp (197kW) and an operating weight of 29,776 kg, the new D7 dozer replaces the D7E. 

The D7 moves 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. Like the D6 and D8T, the new D7 is driven by a fully automatic 4-speed transmission. The transmission continuously adjusts for maximum efficiency and power to the ground without added operator input.

The completely redesigned cab, common with the D5 and D6/D6 XE, raises the standard in comfort and productivity. Operators will find more space, multiple seat and control adjustments for optimal comfort and a 10-inch touchscreen operator interface. A standard High Definition rear-view camera shows prominently in the main display.

Operator assistance systems on the D7 include Slope Indicate (standard with the premium display package), which shows machine main fall and cross-slope for easy reference, and ARO with Assist, which is a grade-ready option bundled with basic blade control and a new set of assist features. The new Cat D7 also packs Cat Grade with Slope Assist, Factory Attachment Ready Option (ARO), Blade Load Monitor, Stable Blade, Traction Control and AutoCarry that automates blade lift to help maintain consistent blade load and help reduce track slip.

Customers can also add factory-integrated Cat Grade with 3D, and the D7 is Remote Control Ready from the factory, too. Of course, it goes without saying Cat Link telematics technology is also included in the D7 package.

The D7 is available in Standard or Low Ground Pressure (LGP) configurations, with a variety of blade and track shoe choices to optimise the machine for the intended application. The D7 can also be ordered with specialised guarding to take on the challenges of Waste/Landfill work and Forestry/Land Clearing. In addition to machine protection against impacts and airborne debris, these specialty dozers can be ordered with an impact-resistant cab, application-specific undercarriage and a specialty blade.
