The Caterpillar 621G is a wheel tractor-scraper used for earthmoving, site preparation, and large-scale material hauling. As part of Caterpillar's scraper lineup, the 621G is designed for loading, transporting, and spreading soil, gravel, and other loose materials across construction, mining, and roadbuilding applications. It typically features a high-capacity bowl, articulated steering, and a tractor-scraper configuration for efficient cut, haul, and dump cycles. The 621G is commonly selected for production earthmoving where cycle efficiency, traction, and material control are important. It is one of Caterpillar's heavy-duty scrapers used in bulk excavation and mass grading operations.
