Everyone always talks about the engine down under and fires, but we never had an issue with the engine down there. We were pretty big on keeping things clean though. We had the engine rebuilt on one of them but the mechanic did it. I can only recall doing governor replacement other than that.
I loved those machines. The engine had a great sound to it and we always found them to be very reliable. They were easy to work on and gave a great sample. We only had wheat, milo, and a little barley, but you would be hard pressed to find a cleaner load of grain. When you asked anyone in the family about a new combine you always heard the same speech. Come back and look at this field in a month. You will see more wheat sprouting from the back of a newer combine that our old Massey.
There were a couple of annoyances. If the wind was just right the chaff wanted to stick to the radiator screen and heat it up. It had a beater in that long duct that was supposed to keep it clean but it didn't work so hot all the time. We got a "spinner" (from a Gleaner I think) and took the ducting off. All was good after that. It was also a pain that if the table was down you couldn't get the battery out. I remember a contraption of wires to get it started in the middle of the wheat field when the battery shorted out unexpectedly one time. If you were in thick wheat that Chrysler would get a little thirsty, too. I could always gauge what kind of a day it was if we had to fill old oil cans with gas and take them out to the combine.
Someday I will buy a Super 92. I probably won't cut much with it, but just the memories they bring back are worth it. I can still hear the starter they put on those things cranking away (usually cause the gas was left on and she flooded).
