As someone who grew up on a farm and spent 7 years running one (few thousand acres so fairly good size), I can provide some background on why this is happening.
The large farms are driving new equipment sales. They are the ones buying the brand new John Deere $700k combine harvesters will all the bells and whistles. The problem is, those bells and whistles add a lot of extra complexity to the machine, making it harder and more expensive to fix. Deere doesn't make it easier since they don't provide details needed for 3rd party repair people (e.g. schematics, software tools for managing embedded controllers, etc). The people buying new equipment don't care about that. Their equipment is covered by warranty and Deere fixes it for them (or replaces it). They sell the machine after it is a year or two. So, they never deal with the crap repair-ability of new equipment. The 2nd stage used market cares a little but not so much either. They can still get Deere to fix it for them, maybe not under warranty.
By the time the equipment gets to the 3rd tier used market, it is already heavily deprecated. The loss in value due to poor repair-ability is not getting fed back up the chain in any significant way which would make the primary buyers change their decision making. They want the bells and whistles and they will pay a little extra in deprecation to get them. The problem for society is that you have a $700k machine that is basically a paperweight after a decade or two. You might was well drive it in the junk pile because no one is going to be able to make it run. At least, not without tearing out heaps of electronics that are no longer working. New machines are utterly dependent on onboard electronic control systems (e.g. ECMs). They won't run without them.
New machines are disposable and that is what the buyers are deciding to choose. You can't put all the blame on companies like Deere. The contrast to old farm equipment is dramatic though. We have an old Ferguson tractor, might be from the 1950s. Everything on that tractor can be fixed. If we wanted, we could make it run like it just came out of the factory. For jobs on the farm that don't need a big tractor, it does them just fine. Probably in 100 years you will still be able to keep it running if you want.

If the value is heavily depreciated by the time it reaches the “3rd tier” used market, why would the buyers in the “2nd stage” used market not factor this depreciation into the price they pay for it when they buy it used from the first owner? Surely people spending $700k on capital purchases know a thing or two about factoring in resell and depreciation into the prices they are willing to pay.
