Jim I have long wanted to try pulling with my TO-20 just for fun. But, my local farm show pull starts out at 5,000# class. My rears are loaded but I'm sure I would still fall into the lowest weight class. I have long concluded that I would want a Sherman or similar low drive to have any success. Can I assume you were pulling with your Sherman in low? Would you volunteer which gear you were running.... or is that a trade secret?
