Thanks for the info. The tractor has been a great work horse aside from this last problem. I took everything apart on the front wheel hub and figured out a way to have my local machine shop make me a new part. It is going to cost $300 -$400 dollars but it should be stronger than the original piece. May end up fixing the other side also.
I did have problems with the electronic hydraulic controls to the point the tree point hitch would not work. Got irritated with the mess and yanked it all out and installed a manual valve. Works like A champ.
So, far the things I have had to do to the tractor have been fairly straight forward. Just takes a little patience to figure it out.
