Gehl had about the same problem. I bought a 250 at an auction one time. Didn't haul many loads and the axle buckled in the middle. Jacked it up and found out it'd been welded on both sides. I plated it and never could get it to hold. I had an old 450 Deere junked out,so I put that axle under it.
I've got no complaints with the New Idea (Agco) 3732 that I've got now.
