I fortunately keep an eye on the temperature gauge and while it got hot, it didn't over heat. Unfortunately to keep it that way, I had to turn the heater on and let it cool down before I could shut it off and clean it out properly. Man it got hot in that cab.
It can clog up like that in a little over an hour and a half in the right/wrong stuff, native warm season grasses. I have started carrying a small broom in the cab and stopping every once in a while and brushing it off or running back to the barn and blowing it off with a leaf blower.
