Introduction
Operators of the John Deere 930 skid steer sometimes face starting issues, especially in cold weather. A common complaint is that the machine won’t start or struggles to crank when the engine is cold but starts fine once warmed up. Understanding the causes of this issue and how to troubleshoot it is important for keeping your equipment reliable in all conditions.
Common Causes of Cold Start Problems
Several factors can cause the John Deere 930 to have difficulty starting in cold conditions:
To diagnose and fix cold start problems on the John Deere 930, consider the following steps:
Cold start difficulties with the John Deere 930 skid steer are often due to battery weakness, fuel system challenges, glow plug failures, or unsuitable engine oil. By systematically troubleshooting these areas and taking preventive measures such as using winterized fuel and appropriate oil, operators can improve starting reliability and keep their equipment working efficiently in cold conditions.

Common Causes of Cold Start Problems
Several factors can cause the John Deere 930 to have difficulty starting in cold conditions:
- Battery Performance Decline
Cold weather reduces battery capacity and cranking power. A weak or aging battery may not provide enough power to turn the engine over when temperatures drop.
- Fuel System Issues
Diesel fuel can gel or become thicker in cold weather, making it harder for the fuel system to deliver fuel properly. Additionally, clogged fuel filters or air in the fuel lines can worsen cold start problems.
- Glow Plug or Heater Malfunction
Glow plugs or intake heaters preheat the combustion chamber for easier starting in cold weather. If these components are faulty or not working properly, starting becomes difficult.
- Engine Oil Viscosity
Thick, cold engine oil increases resistance during cranking. Using oil with the wrong viscosity for cold climates can make starting harder.
- Electrical Connections and Relays
Loose or corroded wiring, poor connections, or malfunctioning relays can reduce power delivery during startup.
To diagnose and fix cold start problems on the John Deere 930, consider the following steps:
- Check the Battery
Test the battery’s voltage and cranking amps. Charge or replace the battery if it’s weak. Ensure battery terminals are clean and tightly connected.
- Inspect the Fuel System
Use winterized diesel fuel or additives that prevent gelling. Replace clogged fuel filters and bleed air from fuel lines if necessary. Ensure fuel lines are insulated or heated in very cold environments.
- Test Glow Plugs and Intake Heaters
Verify that glow plugs or intake heaters are functioning correctly. Replace any faulty components to ensure proper preheating.
- Use Correct Engine Oil
Switch to a cold-weather grade oil recommended for your operating temperatures to reduce resistance on startup.
- Check Electrical Components
Inspect wiring, connectors, and relays for corrosion or looseness. Repair or replace faulty parts to ensure reliable power delivery.
- Additional Tips
Parking the skid steer in a heated area or using engine block heaters can improve cold start reliability. Regular maintenance and seasonal preparation are key to preventing cold weather issues.
