While trying to level out some fresh asphalt millings I discovered an advantage using a Gannon Earthcavator over a standard box blade. With the blade in the standard forward cut position (no rippers) I was able to smooth out imperfections running it in reverse. The weight of the Gannon alone was effective enough produce to a good jop. I don't think you can do that with a box blade. I was able produce similar results using the front bucket on a previously rented Kubota by putting it in the float position but I wasn't able to find such a position on my JD 855. Or am I missing something?
