Apology if I sound rude but let's be honest we both know all those entry level LT have a short lifespan. You did actually a great job keeping it in top shape, you get 10 years because it's a manual Peerless tranny, lot of cheap none serviceable hydro crap out after 5 years or 250hr.
If you think you can fix it for cheap go ahead and make your day, after all it's your time, your money and your tractor!
