Basically it’s unburnt fuel..
U can tell by the smell and it burns your eyes.

It matters not what a dealer said 11 years ago. That's when the fuel pickup mod was done on a then-new tractor. It has NEVER had this smoking issue at ay time in the last 11 years and 550 hours of operation. [And that has included far steeper up and downhill utilization than this incident, many times.]If you think you burnt enough fuel out of what you put in. I'm still leaning it to be an air issue pulling from one of the two pickups in the tank. In this case when the fuel flows forward going downhill, it has to switch to the front pickup and that could let it suck a small amount of air into the rear pickup. Before pulling from the front pickup entirely... JMO..
Even though they claimed it wouldn't at the dealer... I call hogwash...
I've gone down these hill sections 15 or 20 times (and similar ones 100 times) and never any smoking.Has this happened before when low on fuel downhill? Or just this time? Or have you taken this hill before full on fuel and it not happened?
Understand that logic, but keep in mind that the smoke issue was gone before the end of the 2 to 2.5 hour operating period on 11/29/22. I do not even know (yet) whether I can reproduce it . It does not help that I am 330 miles from my farm and only there once a month.Experiment... Fill completely full of fuel and roll that same hill downwards multiple times.. if it doesn't happen then you have an answer. If it does you can look elsewhere for the problem. I find eliminating possible issues the easiest when problem solving not just back and forth chasing possibilities.
I'll check all the possible coolant paths to the intake BUT this incident had the smoke coming out of the exhaust pipe, not from the manifold or anywhere else.certain coolants will put out a bluish/white smoke if gets into or hits exhaust.how close is your overflow tank to the exhaust manifold/exhaust end?
change in orientation as well as hot bottle can open small cracks that close up when cooler temp coolant in tank.
only takes a few drops to cause this so bottle may not look like its losing coolant.
No, I'm sorry, the exhaust is horizontal out the back underneath because this is a low-profile version. Comes out right beside the lower right lift arm sway bar. The air intake is up front, in front of the radiator in a fairly large open area behind the front grille.I missed the fact the fact this had vertical exhaust, not sure where air intake is one that in relation to coolant system
LOL wow I didn't know about low profile.No, I'm sorry, the exhaust is horizontal out the back underneath because this is a low-profile version.

blue/white smoke
Yeah, pretty much impossible to capture on video. I may very well be over reacting since this only happened that one day and by the end of a 2.5 hr operating period it was long gone. The intense smoking period only lasted while traveling 300-400ft through a meadow and then the rest of the incident were shorter bursts lasting maybe 50-75 feet and medium ground speeds.LOL wow I didn't know about low profile.
the only reason I am thinking coolant issue is because of this:
fuel issue will NOT show white.
white out exhaust is coolant.
how positive are you on these colors?
with that being the low profile rear exhaust I suspect no way to safely capture it on video while driving w/o killing yourself.
all I can say is diagnosing an issue ain't worth killing yourself over
