If you would have scrolled down just a bit on the page I cited you would have seen the models/specs for three different front end loaders that would fit a B7200...
If you're clever and good with a welder you can buy plans to build one. CADLoaders
I don't know if they still do but at one time they had a vendor who would sell a kit with the steel.
I agree with the others though that the easiest/cheapest is to buy one with a decent loader already installed.
