A lot of times, people will even pay you to haul that kind of stuff off for them, if they don't know what they have.
Interesting thing about the little old tractors, they were generally just the engine & transmission, with a seat stuck on top of the transmission and wheels attached. No real body or frame to speak of, it was all drivetrain. See this pic for an example: https://cdn1.mecum.com/auctions/gf0311/gf0311-103923/images/...
If somebody want to improve the world and help poorest they should just invent ways to produce those inexpensively and sell them in poor areas. Productivity will skyrocket.

I grew up on a farm in the 60's, before the era of AC and GPS controlled tractors. Most everything was fixable on the farm with a pretty minimal tool chest
Once you attach an implement, then there are all kinds of other functions that it may be used for, like variable rate application. In harvesting applications, there are systems where the combine can take over control of the grain cart tractor while unloading on the go to make sure it stays in the right spot, again localized via GPS. The combine itself will also map the crop yields by its location, and of course automatic steering like the tractors have.
With RTK these tractors can achieve centimetre accuracy and repeatability which opens the door for all kinds of possibilities.
Not to say that plowing, etc isn't exciting work, but with the tractor doing most of the work, you can rock out to tunes in your AC environment. When they install the GPS steering, there is a free minifridge. :-)
If you want to know why a compact tractor costs more than a new car that's a large part of the reason. These are things made to be abused day-in and day-out.
We ended up picking up a '81 Ford that has more than 2000 hours and still runs like a champ.
Old ones are little more than engine, transmission and maybe hydraulics.
My tractor is about five years old, but the haying implements I hook on (specifically, the New Holland 271 baler) are about as old as I am (45).
