Anything JD is worth a good chunk of change. I googled that model and it appears to have a captive (JD style) mounting system. It is set up to use a frame mount that goes forward to the loader brackets. That is something that could be built, but you would want to make a trip or two to the local JD store to take measurements of the back of the frame where the back hoe mounts. If one dropped in my lap I'd make a frame for it, but like you don't really need one. I'd check pricing on a new one and compare with the condition of hers, in good shape I'm thinking in the 3-4 grand range because it's green and says JD.
