I am thinking of buying a northern tool box blade
https://www.northerntool.com/shop/tools/product_200660623_200660623
If i welded a hitch tube to it and attached to hitch receiver welded to an attachment plate. Would that be enough to support it and drag when it's shipping weight is listed at 390 pounds? My gut says it would need some lateral support of some kind. I would only use it in reverse. Does anyone have any experience with the power trac box blade? It looks like it weighs about half what this one weighs.
