A Harley rake is a pretty amazing attachment for seed bed prep. You can level, contour and spread as well as break up root clumps and windrow rocks, roots and other debris. I still use a box blade and landscape rake if there is significant amounts of dirt to move. I just spread and leveled a pile of wood chips this week. It was about a 10 yard pile that had been sitting for almost a year. I distributed the pile with the loader and it would not spread well as the chips tended to stick together from sitting so long. I raised the barrier on the Harley rake and went over the area and it distributed the chips and smoothed it right out in one pass. The main drawback as everyone says is the price. I bought mine used and fixed it up. Be careful buying used. Because of the high cost, most are commercial use and often not well maintained. Many that I looked at had bent frames, many missing teeth, cracked gauge wheel hubs, damaged drive chain and sprockets from not maintaining chain tension and even cracked gear box housings.
