I posted this on the lawn care forum but nobody knew what is was. I bought this from my local Lesco dealer because they wanted to get rid of it because it was sitting around for a while and no one was interested in it. Any way I bought it because it is like a mobile compressor. It has an 8hp Honda on it with pretty big tank and I picked it up for like $500 (brand new). I figured the motor alone is worth that so I bought it. Just wondering what it is for. It has to be for some kind of applicating because it has a hopper on it and the black tube hooks on underneath and the white wand has a little black button on it and that hooks to the other end of the black tube.
