Identical implements branded differently seem to be far more common in these days of constant acquisition.
I have a roll-over box blade that's branded Rhino Ag, but if you look at the Dirt Dog or Bush Hog the only difference you'll find is the sticker that claims what the brand is. Same yellow paint, same model number, etc. So, now it comes down to which dealer will give you the best price.
I got lucky when I bought mine. A new one was quoted at $1200 over the one that had been sitting at another dealer's lot for a couple of years. Buying used might have been an option but ROBBs aren't common and I had to educate the first salesman about what one even was.
I wouldn't use a branded casting with the manufacturer's name as proof that it's made in country. If you're willing to buy at quantity or commit to a several-year contract many suppliers will be willing to accommodate by putting your name on their equipment.
Even history with a brand doesn't work these days as the ownership of the company or sometimes just the name gets passed around like a hot potato. i.e top tier names I no longer trust; Kitchenaid, Jennair. Sure they still make some quality stuff, but some of their offerings are Chinese junk that has nothing in common with the parent company beyond the brand name.
This is an excellent forum to get experienced information. But, do your due diligence. Set your price range, decide how often you'll use the device, determine if you're willing to buy used or not, get as much information as you can, and actually go look at the stuff if possible. Other factors are; is it repairable, are you able to repair it, are parts easy to come by, does the model change often, and can my tractor handle/use it?
So far I've had good luck with Woods, Rhino Ag, Armstrong and Lane Shark. But I'm not a heavy user and I mainly use my equipment to maintain trails and do timber work.
I hope you find what you're looking for.
