That is what I need help with. I have no idea what tractor it goes with. I just used the mount my BX 2360 came with on the blade and it worked fine. This mounting bracket is quite a bit wider than my frame.
I purchased a hydraulic blade and these mounting brackets and frame attachment came with it. I would like to identify them and offer them for sale. I am sure someone somewhere would like to have it for far less than Kubota sells it new.
