- Check if the engine oil viscosity is correct or not, and if not completely change the oil in the tractor.there
- Check and see if the fuel filter is plugged, and if necessary place.
- check if the air intake filter is plugged, and if it is clean or if necessary replace the air filter elements.

- The fuel may not be getting to the cylinder. check the fuel level, the shutoff valve and the fuel filter.
- Check the air filter. It may be too cold for the cylinder to combust mixture of air and fuel.
- Move the throttle back to idle and then half throttle and attempt to restart
Starting diesel engines in cold weather
- Use proper seasonal diesel blends. Winter blends have certain additives to ensure that they remain liquid when it is cold.
- Watch and check for bio diesel percentages
- idle the engines for a time before using, this increases its efficiency and range.
