I am going to buy a 6 foot box blade to aid in plowing very rocky soil for foodplots for deer. Tiller and moldboard plows won't work. I'm considering hydraulic scarifiers which I've read can be helpful to actually pull up larger rocks that are encountered. I'm probably only going to dig 6" at most since our topsoil layer is very thin. Digging deeper when possible only brings up more rocks. Any suggestions for most reasonably priced "quality" unit. I don't mind spending for quality up to a point. I should add that I'm working with NH TC40 DA HST with FEL and 2 rear remotes.
