Very heavy duty chain harrow. We had a large garage torn down this spring, and the ground was semi graded off with a dozer. This left me with about 30,000 sq. ft. of dirt to be smoothed out. I had a Yamaha atv. with a plow blade to get the worst of the grading and I bought this harrow to smooth the rest. I wasn't sure how this would work on what I was trying to do, but it worked great. It brought up stone and leveled the ground just like I hoped. Easy to pull and really works like it should what more could you ask for. Love it!
