I've never seen a Mott that looks like that. The hitch looks completely different and I've never seen a Mott with a round shell over the rotor. Mott was an approved implement for MF tractors and even the old MF catalogs don't show a Mott that looks like that. The gear box looks similar to a Mott but that's about it. Do you have a picture of the rotor? The knife design would tell for sure if it's a Mott rotor. Being it's all painted green, maybe it's something somebody has pieced together from various parts? It HAS TO HAVE a rear roller! You go over a little hill and the rotor scalps, well, then you bend the rotor and you're hooped! The gauge wheels won't prevent that. I think the paint is trying to disguise it as being better than it actually is. Just like a rattle can restoration on a tractor.
