The Cat® D7E dozer was designed to meet growing demand for powerful yet highly maneuverable track-type tractors. By adapting electric drive technology to the unique requirements of dozer applications, Caterpillar® has developed an all-new class of tractor that delivers the best possible balance of heavy-dozing and fine-grading performance. The D7E meets U.S. Tier 4 Final/EU Stage 4 emission standards. The innovative diesel-electric powertrain is designed to burn considerably less fuel and consume fewer fluids and parts for reduced owning and operating costs. Improved productivity and efficiency means getting more work done while using fewer resources.
