I went and looked at the 850 but the subframe was different than the one I need. It looked like the subframe that came with the model 8 backhoe. Different mounts I guess for the smaller tractor.
With slight modification, I have one on a Ford 1910 4 wheel. The tractor handles it well and I had a really low budget at the time. As a matter of fact, I'm looking for new swing chains for my 8a. Anybody now a good place to find some?
I'm glad you were able to make it fit. The Woods BH9000 that I bought came off a Ford 1920. I had to get a different subframe to fit my JD1070 so I still have the old one here to fit the Ford if anybody is looking for one.
