I bought it, for better or worse. But it looks to be of good construction, and the price was cheap considering it's a 7'er.
I've never seen this gearbox on the side before. The opposite side bearing cover looks similar to the ones on the KK professionals, and one of the Italian makes, and the back lids are also knock-off Italian but there's so many outfits making them this style that I wouldn't try to say it's one brand vs another.
The guy has been buying them in racks of 3 or 4 from the other photos, and has sold through a half-dozen so far (going back to mid-last year). Maybe he got some old inventory from the Bush Hog people? I know that parent outfit has some factories here in MN. My brain's pretty mushy from tiller overload trying to figure it out.
I pick it up tomorrow, but given the snow and forecast of COLD, I think it's going to be left in the crate with a tarp on it.
