    Bulldozers are a low-ground pressure machine and therefore are unsuitable for this process. Ground pressure of a 149 kW (200 hp), 23 tonne bulldozer (Cat D7G, for example) is 0.7 bar (10.2 lb in2). By comparison, a loaded dump truck (3 axles, 10 m3 box capacity) generates a ground pressure of 5 to 6 bar (72.5 to 87.1 lb in2,
