A question
How can a tractor pull something so heavy?
A calm, true answer. Then, if the wondering keeps going, the whole episode.
The short answer
By giving up speed. A tractor's low gears turn the engine's effort into enormous pulling force instead of quick movement, which is the trade every strong machine makes.
Its huge wheels help too, spreading the weight so it grips soft earth instead of sinking or spinning. That is why the strongest machine on the farm is also the slowest one.
