This may come as a shock
But I own one. I have a Landspride 84" that I paid $300.00 for at an auction. It does a beautiful finish grade when I put in lawns. It has two rows of harrow teeth 16 each staggered, a cutter edge formed by the I beam that makes up the body of the tool, and a spiked solid roller behind it. The pulverizer will pop out rocks, tear out all grass and weed roots, and breaks up the soil down to a depth of about 3 inches. I have found that the debris stays entangled in the harrow teeth and when you want to clean it, all you do is back up a bit with the tool down then pick it up. Pulerizers are a no brainer tool as they do not drag along large amounts of your soil, it drops it as it goes, so the more passes you make the smoother the ground gets. The roller is spring loaded so the whole tool stays engaged if you encounter a rock with the spikes. The only thing I has to do to mine was replace the harrow teeth at about $6.00 a clip as this machine was well used when I got it.
