The debate came up again this morning around the farmers round table discussion at the country store. Our 4230 started hard years ago. It was that way when we got it. Every one said that's just the way a 4230 is, it can't be fixed. It had several thousand hours on the tach and was tired. New engine kit, head work, injectors and injection pump and it starts as good as any tractor on our farm in cold weather without assistance. I will add that it has two 12 instead of a pair of 6 volt batteries, but other than that all stock and new replacement parts. We rebuilt it several years back and it is more of a utility tractor now, but people call me a liar when I tell them mine will start cold at reasonable temps. Plenty of other equipment will start with a rotary pump, other 404s start cold. Other than a hydraulic issue, why is a 4230 any different than starting a 4020? I guess I'm just not a believer in the myth. Air fuel, and compression and it will start.
