If you want to get a JD loader, the 512 and 522 will fit. The 512 is a bolt on loader, the 522 is a quick detach, would be a huge factor if you plan to operate the tractor without the loader for certain tasks. Bush Hog, Koyker, Great Bend, Quicke, and Westendorf are just a few aftermarket brands that I can think of that sell loaders and mounting kits for about any brand you want. If you are looking for a used loader, the JD 145, 146, 148 (I think), 175, 510, 511, 520 and 521 will all work on that tractor, with the correct mounts. Any JD dealer should be able to order the proper mounts for those loaders. There are older JD loaders, but not sure what the model numbers are. I'm thinking 39, 45,and 48, but won't promise those are correct. The 520, 521 and 522 are quick detach, and I believe the 175 is as well.
