The new Cat D7 dozer offers high-drive undercarriage design, increased performance and the broadest choice of easy-to-use technology features. A fully automatic, four-speed transmission offers optimal fuel and dozing efficiency. At 265 hp (197 kW) and an operating weight of 65,644 pounds (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.
