Fox merged with Brady, then Fox-Brady merged with Koehring, assets of which were assumed by Hiniker, which is the current supplier of OEM Fox parts. Got itIJ
The only thing Hiniker still offers is a flail machine for green-chop. I think the last new Fox choppers were made in 1991 or 92. I know the local Fox dealer sold a new pull-type to one of my neighbors in 1990, and that was the last one around here.
