The Caterpillar 621B is a wheel tractor-scraper used in earthmoving and large-scale site preparation. As part of Caterpillar's scraper lineup, the 621B is designed for loading, hauling, and spreading material in construction, mining, roadbuilding, and land development applications. It typically features a tractor unit with a rear-mounted scraper bowl, apron, and ejector system for efficient material handling. The 621B is known for its heavy-duty frame, high-capacity bowl, and suitability for moving soil, gravel, and other bulk materials over moderate distances. It remains a recognized model in used equipment markets and heavy equipment reference listings.
