What are tractors used for besides farming?

Question

I never really thought of other uses for a tractor, but I saw a video on YouTube called "fell trees, John deere dragging trees" with a tractor clearing out trees in wetlands that was very interesting to watch. That got me curious, what other uses are there for tractors?

Can you use a tractor to do work in conditions like the video that i watched here too?

Answer 1

Snow ploughs.   

Answer 2

I used to use an old gasoline Massy Harris' flywheel to turn a canvass belt to run the water pump to water the hogs in the back barn. The sheep were in the front barn which had modern plumbing. I used the diesel Massy Ferguson to pull the manure spreader. The farmer down the road has hay rides and that's not farming but to sneak a kiss from your girl.
