My gut tells me no as I think that when Hesston went from the 8000 series too the 9000's the mounts changed(9220 is basically a 9230 Hesston). I know there are issues with going from a disc head to a draper on 9260 without the right kit, which are hard to find. But i'm not sure if sickle heads need the kit. I think it made a long mount draper compatible with a short mount disc head. As far as hp I know a guy that gets along with a 16ft hay head on a 8250S which is basically the same hp as 9220.I'm looking to buy a 14 ft hay head from a hesston 8450. Will it fit on my 9220 Massey with same mounts and hydraulics?
