The Caterpillar D4 is a compact crawler dozer used for grading, site preparation, land clearing, and general earthmoving. Built by Caterpillar, the D4 is known for its tracked undercarriage, low ground pressure, and maneuverability in confined work areas. It is commonly equipped with a straight or semi-U blade, rear ripper, and a diesel engine matched to dozing and finish grading tasks. The D4 is used in construction, agriculture, forestry, and utility work. As part of Caterpillar's crawler dozer lineup, the D4 combines traction, stability, and control for work on soft, uneven, or sloped terrain.
