Thanks, it was alot of work. I ended up grinding the stumps.
The grapple is a fabtech. It is a light duty grapple, basically junk. It has no greese fittings or anyway to lube the moving parts. Mine is starting to oval the holes at the grapple arm pins. I have picked up some pretty big stuff with it, alot of stuff i thought would snap it in a half, but it held up for the most part. I had to do a couple repairs/ reinforcements to it to beef it up over the years. I actually ripped off one of the grapple arms one time. Good thing is i only paid $1000 for it, and I can weld and fabricate, so it works pretty good for me. I have gone threw 2 hose sets for it from the loader to the grapple, and countless line repairs. I went to a tractor trailer shop and bought one of there springs to hold the trailer hoses up, and attached it to my hoses then to the loader, and that has seem to cure my problem for the most part.
