Three common ways to abuse a tractor, 1> go full throttle mud running, 2>play tug-o-war, 3>never change fluids and filters, other than that a tractor is a tractor made for tractor environment, theoridicaly. My saying is a tractor should pull what it's pulling or spin the tires.
So what was the exact cost of the fix? tires can run around $1,000.00, how'd you pay for it, credit card, savings and did you say ouch in a upset way? And did the repair come with a taillight guarantee? If it did I'd seriously consider another color tractor, if your like me even $1,000.00 would hurt, good luck with the repaided tractor.
