I wondered what hours would indicate a worn out tractor. I have a Farmall Super C and I can't begin to guess the hours. I don't run it much. I also have a Mahindra and wonder the hours when considered worn out? As cars in the "old" days, 100,000 miles and look for a new one. Now that just seems to be the break in period.
