I really doubt that there is enough brand loyalty in this market to reward a Made in USA sticker. Just look at all the owners looking at the international products as if there is no such thing as American labor, American Manufacturing capabilities, American Environmental requirements/burdens, Legal costs, and the preservation of American design and development capabilities, taxes and safety costs. Yeah there may be a small fraction loyal to the flag, but the vast majority is only interested in getting a low price, apparently also ignoring the lifetime cost.
Check it out, the current forum is filled with guys who can't find parts for their Chinese iron, guys who bought tractors not having an oil filter, guys who insist on getting wholesale parts prices, gotta have red/orange paint (with the high chromium content). You can't do that is this country anymore, the EPA will shut you down (or rather, they are supposed to). Those guys who think the Monsantos and the BPs and the GMs start out from the get go to screw their customers without any experience working for the companies are the norm. BTW, these are the same folks who expect a tractor and an implement to survive massive abuse, stay in balance in spite of hitting tree stumps and bolders, running it out of fuel, using the wrong fuel, rolling it over, leaving the park brake on, and a whole host of trigger pullers, wad shooters, knot tiers and hood waxers. That's what this forum has evolved to.
I wish you luck. Maybe you should put a Made in N.Korea sticker on it to convince your customers that they make it perfect or get shot at their work station.
