Why is my Kubota B3300SU engine difficult to start?

  Dr. Mark RobertsJul 27, 2025
  If your Kubota Tractor engine is difficult to start or won't start, several factors could be the cause. It could be due to no fuel flow, in which case you should check the fuel tank and fuel filter, replacing the filter if needed. Another cause might be air or water in the fuel system; ensure the fuel line coupler bolt and nut are tight. Also, weak battery can prevent the engine from turning over quickly enough; clean the battery cables and terminals or charge the battery. In cold weather, remove the battery, charge it, and store it indoors, installing it only when you're ready to use the tractor. In winter, increased oil viscosity can slow engine revolution, so use oils of different viscosities based on ambient temperatures or use an engine block heater.

What to do if my Kubota B3300SU Tractor engine overheats?

  Marissa FergusonAug 3, 2025
  If your Kubota Tractor engine overheats, several issues could be responsible. The engine may be overloaded, so shift to a lower gear or reduce the load. A low coolant level can also cause overheating, so fill the cooling system to the correct level and check the radiator and hoses for leaks. A loose or defective fan belt can also lead to overheating, so adjust or replace the fan belt. Additionally, a dirty radiator core or grille screens can restrict airflow, so remove any trash. Finally, a corroded coolant flow route can impede cooling, so flush the cooling system.

  If your Kubota Tractor exhaust fumes are colored, the cause and solution depend on the color. If the fumes are black, change the fuel and fuel filter, check the oil level, and clean or replace the element. If the fumes are blue-white, heat the muffler by applying a load to the engine, check the injection nozzle, and change the fuel and fuel filter.
