Common Issues with the John Deere 720 CH

As with any piece of machinery, the John Deere 720 CH has its set of challenges, particularly as it ages. Many operators have reported experiencing issues related to the engine, transmission, and hydraulic system. Let’s delve into some of the most commonly discussed issues and their potential solutions.

1. Engine Performance Issues

The engine in the 720 CH is generally robust, but over time, wear and tear can lead to performance issues. Operators often report that the engine may start to lose power, have difficulty starting, or experience excessive exhaust smoke. These issues can usually be traced to:

• Fuel System Blockages: Old fuel lines or clogged filters can restrict fuel flow, leading to poor engine performance. Regular fuel system maintenance, including replacing filters and checking fuel lines, can help mitigate this issue.
• Air Filter Clogs: If the air filter becomes clogged, the engine can suffocate and lose power. Keeping the air filter clean is crucial for maintaining optimal engine efficiency.
• Injector Problems: The injectors can become clogged or malfunction over time. Regular inspection and cleaning of the injectors can help keep the engine running smoothly.

2. Hydraulic System Failures

The hydraulic system of the John Deere 720 CH is crucial for powering attachments and lifting heavy loads. However, like all hydraulic systems, it is susceptible to wear and damage. Some common issues include:

• Hydraulic Leaks: Leaking hoses or seals can reduce hydraulic pressure, leading to slower or ineffective operation of the lift arms or other implements. Replacing worn-out seals and hoses regularly can prevent this issue.
• Pump Failure: Hydraulic pumps can fail due to prolonged use or poor maintenance. Ensuring that the hydraulic fluid is kept at the proper level and that the system is regularly flushed can help extend the life of the pump.

3. Transmission Issues

The manual transmission in the 720 CH can experience problems, particularly if it has not been maintained correctly. Some common transmission issues include:

• Shifting Problems: Difficulty shifting gears or gears that do not engage properly can be caused by worn-out synchronizers or low transmission fluid. Regular fluid changes and ensuring that the transmission system is properly lubricated can prevent these issues.
• Slipping Gears: Slipping gears can be a sign of worn-out clutch plates or other transmission components. It’s important to keep an eye on these parts and replace them as needed to prevent further damage.

Maintenance Tips for the John Deere 720 CH

To keep a John Deere 720 CH running efficiently, regular maintenance is essential. Here are some helpful tips to ensure the longevity of the tractor:

1. Regular Oil Changes

Changing the engine oil at the manufacturer’s recommended intervals is crucial to keep the engine running smoothly. Fresh oil ensures that the engine parts are lubricated and reduces the chances of overheating or excessive wear.

2. Inspect Hydraulic Systems

Check the hydraulic fluid regularly and top it up as needed. Inspect hoses and fittings for any signs of wear or leaks, and replace any damaged components promptly to avoid hydraulic system failures.

3. Clean or Replace Air Filters

A clogged air filter can significantly affect engine performance. Regularly inspect the air filter, and clean or replace it as necessary to ensure the engine gets the airflow it needs.

4. Monitor Tire and Track Condition

The tires or tracks on a John Deere 720 CH can take a lot of abuse, especially when operating in rugged terrain. Regularly inspect them for wear and replace them as necessary to ensure maximum traction and stability.

5. Store the Tractor Properly

Proper storage can prolong the life of any piece of machinery. Make sure the John Deere 720 CH is stored in a dry, sheltered area to prevent rust and other environmental damage.

Conclusion

The John Deere 720 CH is a reliable and versatile tractor that continues to serve many farms and ranches. With its robust design, hydraulic power, and powerful engine, it remains a popular choice for both light and heavy-duty agricultural tasks. However, like any older piece of equipment, it requires regular maintenance and care to keep it running smoothly.

By staying on top of maintenance tasks such as oil changes, hydraulic system checks, and proper storage, operators can continue to get the most out of their John Deere 720 CH for many years. The durability and performance of this machine have earned it a lasting reputation among agricultural equipment enthusiasts, ensuring its place in the history of farming machinery.
