I bought a harley rake this year to use for yard prep before seeding. I've heard that there is a learning curve to it. I seem to be getting better each time I use it. I'm really starting to like it. What tips can you guys offer on its use? What is the best method when a yard has weeds/grass a knee high? On really hard ground I found that it takes somewhat of a beating, would a pulverizer be best for the first pass?
