I had a interesting conversation with the man the tractor was purchased from today. I had no idea he had this tractor since 1978. It was a trade in at a MF dealer from a farmer that needed a larger tractor to handle a round hay baler that were just getting popular here about that time. He believed the tractor to be a 74 model, but the serial number shows it to be a 72 model, irrelevant actually because MF built the 165 with only small changes for 9 years ending in 75 (other parts of the world could get very similar versions through 79).
About 10 years ago he had #1 hole repaired because the piston sleeve let loose and fell into the engine. 5 years ago both clutches were replaced. Engine knock started about 10 hours of run time after a oil change. He told me with a chuckle that most of the dents were done by his deceased son. Don't know if this interest anyone else, but I like knowing the history.
Knowing the history only makes it more interesting. Thanks for sharing.
