I bought this mower at auction. The previous owner painted it and there are not any identifying markings on it, when I asked them what brand it was they said that they didn't know. The hood on it is homemade, it has a Kubota diesel v1505e, it has a 23" blade on each of the side decks that spin opposite, and a 30" blade in the rear. All the blades have 1/2" center holes. I'm having a really hard time finding blades for it. Please help!
