We have Summit's Plot Mule. It works okay, but you do have to make quite a few passes to break up the ground. It weighs around 450 pounds, and we pull it with a 400cc Honda Forman ATV. It does get tiresome going around in circles ( That is all that our foodplots allow. They are just not big enough to go in a straight line very long ), and I alternate my direction of travel just to rest my arms from the tight turns that I have to make. One problem is that the disked dirt piles up, making the ride bumpy. But by raising the disks until they just barely contact the ground, I can re-level the dirt to some extent.
It is very tough. We have run over small stumps, and too many rocks to count. Only problem that occured was when the nut came off of one of the axles, and the axle rotated out of alignment with another part,but with some finagling, I got it back together again. It is aggravating to ratchet the disks into and out of the ground, but they make a motorized attachment that should make it less of a hassle.
I do realize that this is a tractor forum, and tha ATV has no place here, but I finally convinced my wife that I needed a tractor to do the work. Right now, a local dealer is holding it for us until we get a storage building put up, after that, I can finally cut the grass out on the hunting land. I tried that with our Cub Cadet. Boy was that slow, but that is another story.I do hope to get a tiller to replace the plot mule.
We lucked out with the "Mule". Summit had just come out with it, and displayed it at a local outdoors event, so they gave us the show price. Being close to them too, doesn't hurt either.
