The TC40DAs have a thermostat. Your temp will run in the upper part of the green. I live in East Texas. It gets hot in the summer and I mow all day with it at the same spot.
There is not a radiator screen. Keep the radiator fins cleaned out for max air flow. I wash mine out regularly. I put a hose bid and short hose near the shop to wash the tractor after using it.
Randy you are absolutely correct that there is no screen. Actually the hood has a fine mesh opening and this is also below the battery. There is foam and rubber that is supposed to seal the hood so that all air has to come through those mesh screens and remove most large material. It works good on my tractor, but the radiator always has dirt in it when I wash it out. I take a nozzle and put it in beside the fan blades and direct water out toward the edges of cowling. Looking in front of the radiator, the water always comes out looking muddy. By cleaning from time-to-time, I've never had anything approaching an overheating situation. Engine temperature on our tractors is very stable as long as the thermostat doesn't stick open. If that occurs, the engine will run cold and the gage will never get up to the green area.
