A compact crawler dozer designed for light construction, landscaping, and site preparation, the Komatsu D20 combines a small 3,330 kg operating weight with a 2 m blade and simple direct-drive drivetrain. Built for maneuverability and low ground pressure rather than raw pushing power, it works well on small construction sites, farms, and utility trench backfilling where larger bulldozers are impractical.
