I have seen a number of threads about mounting a tool box on a 790. I had bought a plastic one and mounted it on the right fender but now I've put a 3 spool valve there to run the angle on my blade and eventually a TNT on my box blade. So I bought a toobox at JD (I think it fits the fender of a 990) and mounted it on the front. I made the brackets from some metal that I bought at a HW store. Works great. A few pictures.
