They are still built as a low price entry level unit just as are all the other Big Box Store tractors.
You won't mind if I call you "Captain Obvious" for that insight, which I'm sure, no one else was aware of? You mean, they're built to a certain price point for a specific market? Wow! Who'd have thought? Just like a Kubota BX series?
There's a specific amount of materials and labor that can go into any product at a price point - no matter who builds it. The only way you get around it, to some extent, is to automate as much of the production as possible. But, even that has its limits as you have to amortize the investment in equipment plus some percentage of profits - so that you can maintain and update the production line as required. Any other unique insights you'd like to impart - or do you just have a need to be "right"?
