The only really productive plots are the ones in which I did years and years of throw-and-mow. All those years of mowing tall grasses and weeds down onto the ground built up a little soil. They now turn very easily. It is the newly bulldozed plots that are a nightmare. Although even those will turn if we've just had a rain. But let them sit for a couple weeks in the baking heat of the summer with no rain and they are concrete hard.
A drag harrow, with teeth down, can definitely tear up some ground. It won't turn the ground, but it will definitely expose soil.
I use a disc made by Black Boar implements. I bought an extra tray to hold concrete blocks to add weight to it. I learned the hard way that you must add weight to the disc and not depend on the weight of your UTV to press the discs into hard ground. The black boar disc is up and down adjustable with something like a screw Jack. Start shallow gradually deepening it. When I put it down beyond the range of the jack to support the weight of the UTV on the disc I damaged the frame of my Polaris Ranger. I actually bent the 2-in receiver. My thoughts about the groundhog Max are that it would probably be the same because it depends on the weight of your machine pushing it down into hard ground.
Absolutely true.
I will pull up some of it, but not all of it. But I definitely wouldn't chain harrow perennial clover.
