The only ATV I've ever owned is my 2001 Suzuki Kingquad 300, its been good overall for working. It's not a sporty quad at all, more like a 4wd riding lawn mower with enough suspension travel to keep all four tires on the ground in woods. 3 range transfer case with 2wd, 4wd and 4wd front dif lock, gives you lots of options and the 3 speeds of reverse with the front dif lock make backing up hills or into the trailer easy. It uses 5 forward gears and a centrifical clutch that engages fully at a very slow walk in super low, 1st gear or reverse.
My old farmer neighbor also has a 90's 300 honda fourtrax, rock solid and probably could do 90% of the work my quad does, good all round machines for sure.
