Well, new tires are installed and I'm ready to put down some lime. A torch on the axle allowed one pin to come right out. The other one, I drilled the pin out and then was able to punch it out. The hubs were held in by dow rods as far as I can tell, see pics. I was able to order replacements from mcmaster, I decided to use spring pins instead (should be easier incase of a flat). I did order the dowel pins just in case the springs pins wouldn't hold up. 7/16" 2" long if anyone else ends up getting the model I found. Next weekend I'll give it a try. It shouldn't take too long to lime 10 acres :laughing: Thanks for all the input.
