How do I Troubleshoot a Hydrostatic Kubota Tractor?

Troubleshooting can extend the use of tractors such as the Hydrostatic Kubota tractor.

Although these tractors are sturdy and dependable, as with most heavy farm equipment, breakdowns can happen. Before calling out a mechanic, there are a number of troubleshooting steps you can take.

1. Check to see if there is any smoke coming from the exhaust when you attempt to start the tractor. If the engine will not start and there is no smoke at all, it could mean that no fuel is reaching the engine. Make sure there is fuel in the tank. Check the air filter for any dirt and sediment. Clean the filter out or replace if necessary.

2. Check for a blown fuse link if the electrical components are not working. The fusible link is a loop of wire located next to the starter. Replace if necessary.

3. Check to see if the battery post and wires are dirty. Remove the cables attached to the battery, making sure to lift the negative cable off first. Clean the battery terminal using a small wire toothbrush or a pocketknife. When you replace the cables, make sure to clamp the positive lead first.

4. Blow compressed air through the radiator core if the engine shows signs of overheating. The air flow could be restricted through the radiator. Take care not to bend the metal fins on the radiator when blowing compressed air.

5. Drain the fuel system immediately if you smell gasoline in the tank. Flush out the entire system and replace with the correct diesel fuel. The smell of gasoline mixed in with diesel is usually quite distinctive.
