Why is my Kubota Tractor engine difficult to start?
- LLaurie SchroederJul 29, 2025
There are several reasons why your Kubota Tractor engine might be hard to start. It could be due to no fuel flow, so check the fuel tank and fuel filter, replacing the filter if needed. Another cause could be air or water in the fuel system; ensure the fuel line coupler bolt and nut are tight and bleed the fuel system. In cold weather, the oil viscosity might increase, slowing the engine revolution, so consider using oils of different viscosities or an engine block heater. Lastly, a weak battery could be the culprit; clean the battery cables and terminals, charge the battery, or remove and store it indoors during cold weather.
