I went back on a old trail today and found a old tractor or something. It has a rear axle that looks like a 2 1/2 ton or even a 5 ton axle. Any ways its flipped up side down and the axle would be easy to cut off and take home. Could it be a rockwell, how do i tell? Is there numbers or something stamped somewhere on it? It would be free since i talked to the owner, would this be worth selling, maybe i could trade it for a d60? Ill try and put a picture hopefully someone can tell me what it is.
