Deere seems to have bad relations with their employees, customers, and regulatory bodies.
The shareholders should remove the board of directors.

Firing a board is generally risky, and the shareholders probably haven't fired them because even though the board has, almost objectively, not been good - firing them is likely even worse for the stock short term, and there aren't a lot of long-term, active investors left in the world.

Just for that failure, they should all likely be gone.
They have gone from $4.3b in operating income to $14.5b in three years, while their sales nearly doubled. That's an old industrial company boom the likes of which is almost never seen by those types of companies.
By comparison what you're calling catastrophic is entirely trivial. It's not even in the room as a consideration compared to the soaring profits. Nobody is removing a whole board with that kind of profit growth.
Yes their profit is up, no it is unrelated to the concerns
The company is acting in a way that luts the whole food system at risk
They should be disbanded, by force. I recommend replacement with a farmer cooperative
If the goal is some vague "easy to repair" mantra, then tons of things in an advanced economy are going to be hard to repair since technology gets more and more complex. Limiting future inventions to also include "easy to repair," under some complex definition, will limit some innovation. Car engines were once easy to repair, then we added all sorts of emissions control, making them harder, and then as computerized control systems turned out to provide massive benefits (lower gas use, more engine life, better control of timine, fuel injection, and ahost of other things), it again got harder to repair. And engines are simple. Should your internet browser or smart phone allow any neanderthal to consider it easy to repair? Or does an increasingly advanced and complex technological environment reasonably make things harder to repair, even while providing advances that are providing benefits to consumers?
The role of govt is to make an environment where companies compete, and given that JD owns < 40% of the North American Ag Machinery market, it seems there are ample other choices.
Economically, and historically, legislation effectively putting price floors or ceilings on goods (in this case price not as $, but as tech requirements and cutting into company ability to sell goods) pretty much every time comes back to bite consumers. This is econ 101.
