My wifes grandad farmed his whole life. They raised 5 sons and a daughter on the farm. One of his tractors was a '40 John Deere B. I'm not sure how long he ran it, but my FIL and his brothers remember running it. Eventually it was parked in favor of newer and bigger equipment. About 20 years ago or so, a local gentleman bought it and restored it. We would see him driving the tractor in parades and the inlaws would mention that it was grandpa's tractor. My wife saw it advertised on Facebook marketplace a few weeks ago so we went over and bought it. Here it is, loaded up and headed home. Its been too cold since to get pictures of the 4th generation (our kids) on it, but we will. The wife's grandparents have passed away and her uncle now lives on the homeplace and farms the land. They have a family get together every spring when the weather warms up. We will haul it out this year for hayrides. It should be a good time. My wife has second cousins that have kids the same age as ours. That will make 5 generations that have been on the tractor.
