Mutt, I think the power landscape rake is one of the coolest tools I've ever used. It will move and winrow any size rock that will fit between the ground and the 3 pt hitch. The roller on the bottom has standard steel 3/4" by 3/4" bars attached length wise to a 6" drum 8' long. It spins forward kicking everything that is in front of it forward even pulling some stuff out of the ground. There is another roller just above it, same 6" roller, no bars that has an adjustable gap to throw back smaller or larger amounts of material. Typical usage is to angle it left or right so all the debris is gradually placed to one side or the other. In some occasions, the ground may be so inundated with debris it requires a second pass since some slides against the angle. Roots, weeds, and of course rocks can continually be moved further over, ie. you can drive right over a winrow and continue to push it over to make it larger so that when its time to pick up the debris in the loader you have some bulk to deal with. It has 3 sets of hydraulics. The angle ram, the height adjustment ram, it works on a floating system that allows imovable objects to be gone right over with no damage. The 3rd hydraulic set of rams simply lower a spring scarifier bar. The best way to use the rake is with first having tilled, ripped or discing the ground unless your not trying to open it up and pull out debris underneath as in just clearing some pasture land. I used the 6' rake and the Kubota 4850 would smoke the rakes clutch because of its PTO power. The 8' rake has a much bigger clutch and big tires on the rear for gauging the depth. I have not been to the Harley site but did notice that in one of the Kubota brochures Lgrande series, one of the tractors had a power rake attached to it. Rat...
