Well.. farming equipment are high 6 figures 7 pieces of business equipment (the lifetime operating costs are definitely in the 7 figures.) These are owned and operated by people who I would expect to do this type of research and critical thinking. These aren't normie consumers buying everyday appliances or electronics.
However.. farmers are a weird bunch and they are blinded by brand loyalty or will only buy from an "American" company which ironically allowed JD to stomp all over them because of their dominant market position.
I'm no farmer, but brand loyalty might have practical reasons, such as compatibility with attached farming equipment (plows?).
