Out of all the attachments for lawn prep does anyone use something other than the Harley? I use the Eliminator alot to prep for lawns and haven't seen anyone else use it, we also have the TR3 tractor rake that dad uses and have always had good results. Has anyone used the RotoDarin? Alot of times we have to till up existing grass and the rototiller kind of 'chunks' it and doesn't leave a good product to work with, anyone else have this problem? What other attachments do you use and why?
