Answer:
- By weight, the tractor is much larger than the weight of any man or animal, but its size is such that its weight falls on a large area. Because of this the load (pressure) per square centimeter of the bottom surface of the tractor is greatly reduced compared to a man or animal and does not easily sink into marsh soil.
