: I can't seem to find out what I've really got. If anyone can shed some light on my problem, please drop me a line. Casting number on the torque box: AM4455-7, Cast number on plate behind shifter: 221826, Casting number on engine:AM4458-4, serial number stamped on engine block 17-4157M. I just bought the tractor from m father-in-law and he thinks it is a 1962 D17.
The serial number on the tractor will be on the bell housing, either on the right or left side...I can't remember off hand. It will begin with D-17. I know the tractor you have is a D-17 because the 17-4157M number is the engine serial number and the model 17 engines were used in D-17 tractors. Although with a number that low, I would suspect your tractor is a 57 or 58 model. Also, the M indicates that the engine was factory equipped with pistons to give a 7.2 to 1 compression ratio, used for gasoline. The LP tractors ended with a V because they have the 8.2 to 1 compression ratio. Not relevant to your situation, but just a little info for those interested.
