I was noticing higher temps on my guage when working with the tractor. At first I though it might be normal for the temp to go above the mid point, but then it started to move closer to the red line. I thought it might need a thermostat, because I cleaned the inlet grill in front of the battery, and pulled the screen in front of the rad and blew it out. Neither one was really plugged. Then I peeked behind the battery, and noticed the rad was almost completely blocked with funk. How often does this happen to a bx during cutting season? I've only had mine really for about 50 hours ( I bought it used with 100 hrs.) so I was surprised that I almost cooked it. I checked the screens every week and thought that would be enough. I don't know if it was partially clogged when I got it or what.
