I was bush hogging a lots of weeds and seeds/fluff was everywhere, including the grill screens. Eventually the temp gauge started climbing, so I knew the screen in front of the radiator was clogged, which it was. The problem was getting hold of that screen to pull it out. I finally managed to get it out, but afterwards thought of a new/better way. Duct tape. Yep, just pull the screen out and put an inch or so on the screen creating a tab to grab onto-now it comes out easy peasy.
