Screen with really small holes and a rotating brush.
Cool, do they work?
We had things like that for water intake screens, keep the algae and trash from stopping flow.
Yup
Yeah, those work pretty well.
My old tractor I traded off on my new one was bad about overheating. Small fins on the radiator plugged up within a couple hours, and the temp gauge would start rising... Stop, fire up the compressor, and blow it all out... Good for another couple hours.
My new tractor though, has much more space in fins of the radiator, and runs absolutely cool. I just blow it out once a month or so. It also has front screens that slide out, and you knock the obstructions off on a tire, and slide them back in.
MUCH better. Much.
