Sorry to hear the neighbor is so ungrateful. Before I knew he owned a tractor dealership I stated I would have paid for the parts. If I owned a tractor dealership my service guys would have picked your tractor up and returned it repaired free of charge. It would have gone to the top of the work list. I guess no good deed goes unpunished.
I agree 100%.
I wouldn't give that guy the time of day from this point on.
