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 hydrostatic or powershift drive depending on model year. The D4 is used in construction, agriculture, forestry, and utility work where traction and control are important. As a crawler dozer, it is designed to push material efficiently on uneven or soft terrain while maintaining stability and operator control.
