Bought a 169 last year. Was looking at the serial number. I think this baby was made around the last of the run of production. I have failed at finding how to read the rest of the number 205 is garden tractor? and 0048 i can not find i did find 0038 is a 107 not sure on what the U is or meaning, 523921 is September or early October. I'm think think that's what i read. Any guidance would be greatly appreciated. I'm hoping 0048 is a 169. Thank you in advance!
