Fulton County Ohio | You are running an open center hydraulic system. Do you have the correct orifice restricting flow to the sprayer? That tractor has two water pumps. One for the engine and one for the tranny. The one to the tranny can air lock and cause overheating. If a hydraulic lever is engaged but oil is not allowed to flow on this model it will overheat. I assume all your radiators and screens are clean. Good luck | |
