Caterpillar D4 Bulldozer

The Cat D4 hydraulic crawler dozer combines the power of a larger tractor with the versatility and maneuverability of a smaller machine in one package to meet a wide range of job applications. With its comfortable operator station, excellent visibility and simple joystick control, the D4G is everything you expect from Caterpillar and more! The Cat D4 series has been in production since the 1950’s, and the fact that these dozers are still in production says a lot about their quality, design and durability. Be sure to always put on high quality replacement undercarriage and parts when needed to keep the CAT D4 dozer moving.
