I think it is all quite POSSIBLE.
Incredibly unlikely, very IMPROBABLE - but still POSSIBLE.
======================================================
There was a time when Micro-$oft had no "protection" on what it called its operating system - Dross somethingorother.
You were SUPPOSED TO pay for it, but it was widely distributed via sneaker-net and widely known that they wanted market-share (more importantly MIND share) for the long term more than money for the short term.
OK, so software copies are a lot cheaper to make than tractor copies, but if this dealer is determined to drive out all other brands in the area this COULD be a lost leader for a long term goal.
=======================================================
Again, COULD BE - although incredibly unlikely,,,
Another possibility is that after 40 years they are about to close up and retire anyway.
There could be all sorts of reasons for a massive fire sale of new inventory.
My imagination just went to the post about GM and I remembered the massive closings of Dodge/Plymouth/Chrysler dealerships.
If JD are about to shut down some franchises ... if, If, IF, maybe this dealer has a NEED to off load all his new inventory and become a used equipment dealer.
Not to start a false rumor, so let me re-state that; "If JD is about to pull THAT dealer's franchise maybe they have a need to off-load all their new inventory and become a used equipment dealer.."
If that were the case my guess is that they would limit it to a model (or two) for a while to hold onto the secret.
Guesses, all guesses (-:
