If the exhaust fumes from your Kubota Tractor are colored, the cause varies by color. For black fumes, change the fuel and fuel filter, check the oil level, and clean or replace the air cleaner element. For blue-white fumes, check the intake air heater function in cold weather, heat the muffler by applying load to the engine, inspect the injection nozzle, and change the fuel and fuel filter.
