Anyone know why a PTO winch won't work with a SM420 adapted to a three spd with plate adapter? I know that the transfer is rotated down a few degrees, but I was looking under a PTO equipped 40 yesterday, I didn't see how that would create any problems. I'd rather not wait until after my 420 is installed and after buying a PTO winch to find out theres no way to make it work. If it just means a little grinding or welding, well worth it. Anyone?
