  If your Kubota Lawn Mower's engine is difficult to start, several factors could be at play. The fuel tank or fuel filter might be clogged with dirt, requiring you to check and clean them. A malfunctioning spark plug could also be the culprit, so inspect and replace it if needed. Additionally, dirt or water in the fuel system can cause starting issues, necessitating a fuel system cleaning. In colder weather, the increased oil viscosity can slow the engine's cranking, suggesting the use of oil suitable for winter conditions. Lastly, a discharged battery will prevent the engine from starting, so ensure you charge or replace the battery.
