From thermostat housing to top tank, thru the core, to bottom tank, back to block.

If you really want to test your theory, take a heat gun, and with the tractor hot enough to keep the thermostat open, take the temp of the top tank vs the bottom tank. You will see that the top tank is around 12 degrees or so hotter than the bottom tank. That means the flow is from top to bottom in the radiator.

Now, if coolant flow is low, (bad water pump for example) the coolant spends more time in the radiator and the temp difference will be greater. If the fins are plugged with dirt, the temp difference will be less. (the fan's air flow can't remove much heat)
