JD 4320/400cx mount repair.

I have an '09 John Deere 4320 with the 400cx loader. It has 3k hours on it. I had trouble with the right hand mount, uncoupling with heavy use. After looking at the wear of the mount and mast I decided to replace the mount thinking it had the most wear v/s the mast, plus it was cheaper

It didn't work and still uncoupled. So rather than buy a $1k mast, I did a small mod that should have been incorporated in the first place. I did both sides. It can't come apart now.

Nice idea. I will keep in in mind. I only have 2200 hrs. now.

You will probably be fine. I bought this rig used and the selling dealer said it was used almost exclusively to stack hay. So the loader was always in use. The drawbar, 3 point and pto looked new.
