I have a Polaris Sportsman 500. It is an inexpensive ATV with a good amount of power but I do not think it would hold up to heavy plowing of acres. I use mine to disk 1/2 acre at the most and then also haul firewood in a cart perhaps 6 or 8 times per year. Otherwise I use it very little. It is a little over 1 year old and has worked well except for the carburetor gumming up from gas containing ethanol. I switched to ethanol-free gas and put in some sea-foam engine treatment and all is well. But I would not want to put too heavy of a load on it. For many acres, find an old tractor second-hand. For less than the price of even the cheapest ATV you can get an old tractor. And for $9K you can get a brand new 25HP tractor at Northern Tool.
