I bought an infrared thermometer and bought a bottle of Prestone Rad Flush (this one: https://www.amazon.ca/Prestone-AS105-Radiator-Flush-Cleaner/dp/B00B99U088)
I then ran the machine for a while to get the block temperature up to 180 as read from the outside (took about 30 minutes at 2000RPM) with the coolant cap off. Used the thermostat to watch the rad fluid and lower hose temps. I never got it to climb past 180 really, but the operating temp seemed linear to the RPM, and I didn't want to push it too much higher.
The fluid in the rad neck got to ~140 degrees or so. The lower hose got to ~110 degrees. They pretty much stayed there
Once I shut the tractor down, the fluid in the upper rad neck went up to ~155 degrees.
My main thought is that the rad temps never got to where they should be if the thermostat and water pump were both operating. Given the amount of rust and gunk in the system, I think it's realistic that one or both is either clogged or junk.

But, on the other hand, there is a secret language that our mechanical companions readily do speak. It is an interesting form of communication that involves all the senses of the listener. In this series we are going to investigate and learn the basic rudimentary skills of understanding this lingo.
