Talked to the headsight guys to see what they know... its not isobus. its proprietary and JD looks like they are not sharing... hmmm.. [edit: it is the isobus connector, but not open for use like isobus. different somehow at the signal level].ISOBUS (technically j1939 actually) is a great fit for this sort of thing. MacDon and Honeybee need their own ECU on the header is all. In some ways this simplifies things rather than having an increasing number of wires for different header functions that weren't around years ago. If everyone adopted a standard set of PGNs (j1939 messages) that would be a boon to header inter-compatibility. But this is John Deere here... they no doubt require NDAs and hefty license fees from the 3rd party manufacturers.
"....does not plan to make available or support development of a compatibility bundle for the X9 combine"... That seems pretty definitive. shame..I'd be really surprised if it wasn't j1939 on canbus. Everything else in a John Deere is. I'm not surprised they aren't sharing the PGNs they use, at least without some pretty nice pay to play fees and NDAs and such, which they will have to do as there are crops that require headers they simply don't make. What a bold milestone it is when John Deere has now added what's effectively DRM for their headers and attachments, if true.
Yup, I think your right and they probably need a controller for all the valves their new header has too. But agco stuff has the basic signals AND canbus on the legacy connector so that they don't block existing headers, and still allow new stuff. Time will tell I guess if this is a good play for them... ultimately farmers decide the outcome by voting with their wallets.Don’t you think that because John Deere uses a half dozen or more sensor channels across the width of their cutterbars so the thing doesn’t bite the ground on a convex knob or ridge in the field accounts for some of the compatibility issues.
Unless I’m missing something, no one else lifts or twists the header automatically when the cutterbar is about to encounter trouble in the central area of the header.
Presumably they would use the same signals to control their new hydraulic hinged header as well.
I don't think the main complaint is that the old deer heads won't fit on the new machine, rather its the short line headers from MacDon, Honeybee, Geringhoff, Midwest and the rest won't work because of the proprietary electronics from Deere. I'm sure MacDon and Honeybee would fit with a change to there adapter. I don't know what percentage of buyers who would be looking at an X9 would want to keep their old headers, but around here its not uncommon to swap the adapter plate and put your old header on a new machine. There is several Deere machines with Case branded Macdon headers, There is a guy with 4 claas machines and each macdon head has different colored plastics on the end of the header.I think your forgetting a basic thing with the headers regardless of the electrical. All deeres existing headers fit a 55" feederhouse, not the 67" feederhouse on the X9.
