I have a Harley pro 6 rake and I have just installed a carbide tipped roller on compared to replacing it with the stock bar roller and I am waiting for my new machine to come in to try it,in the meantime I have been using a friends Cat skid steer w/a harley rake,it is much different than using one on a three point hitch but it works extremely well.If you have the doe to get one it is well worth it,just the time saved in labor is worth it and the things you can do w/it are just about endless,from grading driveways to stripping sod,or just putting in an everyday lawn and once you get the hang of runnin' it the only hand work is to drag a grading rake over the caster wheel marks and you really don't need to do that,it just makes the finished product look that much better.
