D7E (U.S. Tier 4 Interim/EU Stage IIIB/Japan MLIT Step 4)

Medium Dozers

The Cat D7E 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 innovative diesel-electric powertrain is also 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. The D7E meets U.S. Tier 4 Interim/EU Stage IIIB/Japan MLIT Step 4 emission standards.
