Bought my First tractor at 13 from a sale. I was shaking when it got knocked down. International 574 - £380. Still have it. Does 30mph flat out goes straight off the Rev counter. Good brakes, Straight gearbox no TA. You will not beat them for a road runner at 16. Fords of that era are horrible in comparison, John Deere too slow, leyland go well but don’t stop, masseys are way more expensive and are horrible to drive imo. David browns are too slow but cheap.
