Title: Use a Nail Instead
Review: I bought this with some hope that it would break the matting on turf grass, I wasn't even looking for aeration. This product is useless for either endeavor. A cinder block lacked the weight to punch through the grass. I modified the unit by welding two rods to the plate so I could attach weights. Started with 30lbs and still didn't work. At 60 lbs the unit worked but you could imagine pulling that weight around. This thing has a few design problems - if you pull it, you are lifting its weight off of the ground. If you push it, you might as well use no weight at all, your body acts as the weight. You will be guaranteed some exercise with that approach. Oh, I even tried sharpening the blades with a grinder. If you crawl on your hands and knees and use a hammer and nail, the results would be better.
