Yard Tuff Drag Harrow 48" by 60" DH045
Product Review (submitted on July 17, 2013):
If you have light work that needs to be done, this is the item for you. If you're looking for a heavier duty harrow, this is not the item.
Recommended improvements: instead of linking the chain (to pull the harrow) to the chain link fencing, weld a connector onto the metal brace instead. After just the first pull the chain link fencing has stretched out and I'm now worried about it breaking off. I've asked a welder to weld a small piece onto the brace for me to hook the chain to instead.
It shows that you can put blocks onto the brace for a little bit of weight but, the bricks fall off. So you'll need to somehow attach the bricks to the brace.
