Hi early riser - I've never known anyone to own one, or the other similar type products. I'm a skeptic as well. They recommend a 20-40 horsepower tractor minimum (which probably means 40hp). An ATV the will generate enough hp at very low speeds - but it will work hard, if it can get enough traction.

The first year we planted, our 55hp tractor died 1/2 way through disking. To finish - I used my 8 cylinder Jeep Grand Wagoneer to pull the disks. I'm going to tell you, I could pull those disks, but my jeep was on the verge of overheating the whole time. If I stopped on any kind of rise, I was done, and they do NOT back up. I ended up taking the disks in half to finish (5 acres) I cant imagine trying it with an ATV.

I know you soils have less rock, so maybe you could get away with it. However, for less money, you could buy used extra disks and drags, and leave them at your feilds. These products look more like a garden implement to me.

Don't get me wrong, an ATV can be a great assest in seeding and cultipacking - I just do not see them doing a great job disking, definitley not plowing.
