Old people loose their hearing, memory, and circulation in some body parts but certain vibes stay for a lifetime.:laughing:
Transmissions are usually the first expensive item to fail in those tractors so test it. Drive the tractor until the Trans fluid is up to operating temperature. Chock the front wheels with a couple of 4x4 blocks on level ground to determine if it is capable of spinning the wheels. Repeat test in reverse. If the seller doesn't want this done, thank him for his time and get in your truck and leave.
