1970 something John Deere JD300 industrial tractor. Gas engine, 2 range shuttle shift transmission. We've owned this thing since the mid 80's. It's 50 years old so it has wear and leaks but doesn't smoke. Engine was rebuilt probably 30 years ago but doesn't have a lot of hours since we had other tractors. Bucket cutting edge was rebuilt and is perfectly straight. It's not pretty, fast or comfortable but it's an industrial model and is strong. PTO works great.
