I have an old simplicity two wheel tractor, implements include, tiller, sickle mower, reel mower, sulky to ride on behind. Some one has put a set of old mudgrips on it for tires. I dont have a clue what to do with it? Do these things have any value? It needs some TLC and would be good to go. If anyone knows much about these things I would love to hear your comments. Thanks for reading.
