RE: Atv or small tractor?
definitely go with the tractor. there are so many more uses for them than an atv. like others have said, implements for tractors are plentiful, strong, and don't cost an arm and a leg.
i've got a 35 hp deere, with a 2 row corn planter, 10' boom sprayer, bush hog, 2 bottom plow, boxblade, disk, and grooming mower; plus i can rent fertilizer spreaders and a 250 gallon sprayer from the co-op. it'll do just about anything except take hostages.
