Difference between bulldozer and car
Bulldozer may have the same engine power as a car, but it moves more slowly and its body is much heavier than a car.
Let's see the differences between the car with 1500cc engine and Komatsu's bulldozer, D39EX. The engine power is 81kw and 79kw. They are about the same.
The car can run at 100km/h or faster whereas the maximum speed of the bulldozer is only 8.5km/h.
The weight of the bulldozer is about 10 times heavier than the car. With the heavy body and the slower speed, the bulldozer gains big power to push soil.
