Deere made a decision some years back that small dealers that couldn't meet their revenue requirements would be phased out, and they were unceremoniously axed/rolled into larger dealerships. It felt that was a defining moment for a company, where customer satisfaction, long-time dealer and customer loyalty, and established relationships were eclipsed by a company demanding a stronger bottom line--they no longer wanted to waste their corporate resources on the lawn and garden crowd if they couldn't generate "x" dollars in revenue. They did their math, they formed a strategy, they focused their efforts where they felt they'd be most profitable. More populated areas that could hit the target on small machines stayed, the smaller ones went.
All companies need to be profitable, but it is the assemblage of customers that make them so. Years ago 'made in the USA' was a strength of JD's business, but as they've outsourced (the rule for companies squeezing tenths of a cent out of each fastener), 'assembled in the USA' is about all you could hope for now. No different than automakers.
They made decisions that opened the door for other lines to get firmly established in that smaller market and earn a reputation--good, bad, or otherwise--and creep up the frame size/hp ladder. Had JD's resources been put into squashing competition early on, the situation would probably be different--they are massive, and market well.
Kubota is smaller, and makes quality equipment. They have enough brand recognition and following to start leaning into the Ag market.
When I was a kid, 'made in Japan' was what 'made in China' is today. Japanese products are now considered top quality--superior in many cases, where American products have largely disappeared. I have tried to find and buy US products, but it is getting harder and harder.
If you're buying Ag, that's the basket JD put the bulk of their 'tractor eggs' into years ago--it was a conscious decision.
I really enjoy my JD compact tractor, its ergonomics are great, it is reliable, the Yanmar engine is great, as is the Chinese/Indian loader, and I couldn't pass up the deal my former dealer (RIP) got me.
TBN has a lot of small owners, and that's not where JD makes their money.
