My To-30 overheats after about 45 minutes of brush hogging. I've flushed the radiator and replaced the coolant (50/50 antifreeze and water). I've felt the top and bottom hoses and they're both hot, so water is circulating. Radiator is blown out from the Fan side. Doesn't matter.
One thing that is practically missing is the Fan shroud, which someone cut away before I got the tractor. I am wondering if the fan's operation is totally inefficient without the shroud, causing overheating. Thing is, if I mow in grass where I can get some chaff and seed airborne, the radiator will get a mat of chaff on it, indicating that air is flowing over the radiator. So, it's not clear what is causing this problem. Any ideas?
