'51 Fergie, bought it in 1977, I did a complete engine rebuild in 2001 after a valve stuck and went through the piston. It's simple, easy to work on, and runs like a champ although I don't use it much anymore. I mostly used it for hauling logs for firewood, but I quit cutting my own wood in 2011. Worked good for snowplowing too, although I have a 4WD truck and don't really need the tractor anymore for that.
