Unless you look very deep, chances are you cannot even find who actually makes your parts or the parts that go into your part. Companies buy things from other companies and simply rebrand them. For example, Cub Cadet yard equipment sold at Big Box stores is actually made by MTD even though everything looks like it is from Cub Cadet. Cub may still actually make stuff exclusively for dealers, but not too sure. On a disappointing note, my big, overpriced Cub Cadet riding mower, although a bit faster due to a wider path, cuts my 3 or so acres of grass no better than the old Craftsman mower I have. (Cup holders on a mower are useless as the jostling causes my beer to foam excessively.)
On an equally interesting note, some stuff that looks like it is a secondary brand may be made by a dependable company or include parts from quality companies. For example, I just bought a Powermate generator for about $800. I wanted a Honda engined generator, but couldn't justify the massive price difference for the same or less wattage. The bright side is my cheaper generator is made from Honda, Yamaha, and/or Subaru parts. (A Honda equipment dealer confirmed this and actually recommended the Powermate for this reason.)
cub cadet has been owned by mtd since the 80's but in the 2000's starting making them cheap like everything else. all my motors are Honda or yanmar and nothing but green tractors and orange power equipment for me. all bought at local mom and pop stores not big boxes. the whole thing with craftsman and other brands cheeping out over the years makes me sick to my stomach.
