I just got an old george white post hole digger that had a cracked top hitch mount. Took it to get welded and it turned out perfect. One problem though, when I went to mount I found out the drive shaft is seized and will not slide. I've tried penetrating oil and even chained one end to my truck and the other to my tractor to see if I could pull them apart. The truck got dragged about a yard...I was told just to try hooking it up to the pto and using the 3pt to break it free,but I've heard stories about really doing a lot of damage to the pto. Anybody have any ideas? (I don't have access easily to a torch) Thanks
