The Cat D3 Series Consists Of


Caterpillar D3 Bulldozer

The Cat D3 hydraulic crawler tractor began manufacturing in 1973, and between 1975 and 1978, Caterpillar added a direct injection engine and sealed and lubricated tracks (SALT) The K series of small dozers are designed to optimize speed, transportability, maneuverability, versatility and finish grading accuracy. These crawler dozers are ideal for residential construction performing such tasks as clearing and grading lots, sloping the sides of roads, back-filling, and final grade work for landscaping and driveway construction. The fact that this bulldozer is still in production says a lot about it’s quality, design and durability. Be sure to always put on high quality replacement undercarriage and parts when needed to keep the CAT D3 dozer moving.
