The plugging of radiators and their screens in a never-ending problem. The bigger equipment has fans that can reverse themselves automatically and blow out the coolers. Sub-100HP tractors don't have that. I'm no fan of battery powered equipment, for the most part, but I bought the milwaukee m18 blower. Battery lasts 10 minutes, but its enough to blow out the two screens and the radiator, condenser, hydraulic and transmission coolers a few times a day. Whomever invented slide-out cooling stacks is a genius, but again..on the small machines...no such luck.
