Finally, John Deere came trough with a new Instrument Cluster. It now starts relatively smoothly (single stumble and puff of smoke). The new IC apparently lights off the glow plugs. Light goes off, and immediately start, triggers a second longer activation timer of the plugs (2 minutes). I know that to be the case, as leaving it on longer post glow light extinguishing, results in the same kind of cold start, as before the replacement.(bad stumble,Smoke but significantly shorter in duration. Started today immediately when the glow light went off and ran great immeditely. Well worth the wait for the fix.
The above goes for the new machines too.
