John Deere's 820 and 2010 track loaders, introduced in the early 1960s, were designed for rugged construction and agricultural tasks. However, like many vintage machines, they can develop issues over time. One common problem is the inability to free-wheel, meaning the tracks are locked even when the machine is in neutral and the shuttle lever is in the "TOW" position.

While the John Deere 820 and 2010 track loaders are robust machines, they require regular maintenance to keep them operating smoothly. Addressing issues like locked tracks promptly can extend the life of the machine and ensure it continues to perform effectively.
Common Causes of Locked Tracks
- Steering Clutch Bands Seized: The steering system in these loaders uses bands that can become seized due to prolonged inactivity or exposure to the elements. This can prevent the tracks from disengaging, even when the machine is in neutral.
- Final Drive Issues: The final drive system, which transmits power from the engine to the tracks, can develop problems such as worn gears or bearings. These issues can cause the tracks to remain locked.
- Hydraulic System Failures: The hydraulic system controls various functions, including the release of the steering clutches. If there's a failure in the hydraulic system, it may not disengage the clutches properly, leading to locked tracks.
To diagnose the issue:
- Check Steering Clutch Operation: Ensure that the steering levers move freely and return to their neutral position. If they don't, the clutch bands may be seized.
- Inspect Hydraulic System: Check for any signs of leaks or damage in the hydraulic lines and components. Low fluid levels or air in the system can affect clutch operation.
- Test Final Drive: With the machine off, manually rotate the tracks. If one track moves while the other doesn't, it may indicate a problem with the final drive.
- Lubrication: Applying penetrating oil to the steering clutch bands and allowing it to soak can sometimes free up seized components.
- Hydraulic System Bleeding: If air in the hydraulic system is suspected, bleeding the system can restore proper clutch operation.
- Component Replacement: In cases of severe wear or damage, replacing the steering clutch bands or final drive components may be necessary.
To prevent future issues:
- Regular Operation: Regularly operating the machine helps keep the hydraulic system and steering clutches in good working condition.
- Proper Storage: Store the loader in a dry, sheltered area to protect it from the elements.
- Routine Maintenance: Regularly check and replace hydraulic fluid, and inspect the steering and final drive systems for wear.
