Landfills are a crucial part in improving the cleanliness of our air, water, soil ... even the quality of our lives. Putting an innovative, conservation-minded track-type tractor to work on the landfill just makes sense. With its unique diesel-electric drive technology, it puts out fewer emissions and uses less fuel than conventional tractors. Like all Cat track-type tractors working in landfill applications, the D7E is a heavy-duty machine with waste handling guarding to safeguard uptime and support your business. It’s a powerful and highly maneuverable machine for dozing and compacting waste, and at the end of the day, will seamlessly convert to doing the fine grading required to place just the right depth of cover material.
