Massey Ferguson 4707 Problems

The Massey Ferguson 4707 is a popular tractor model known for its reliability and performance. However, like any machinery, it can experience issues that require attention. This article will explore common problems faced by Massey Ferguson 4707 owners, their causes, and potential solutions. Understanding these issues can help operators maintain their tractors effectively and minimize downtime.

The Massey Ferguson 4707 is a versatile 74-horsepower tractor that’s part of the Global Series. It’s designed for various agricultural tasks, from hay production to general farm work. While it’s generally a dependable machine, some users have reported specific problems that can affect its operation and efficiency.

Engine Issues

One of the most critical components of any tractor is its engine, and the Massey Ferguson 4707 is no exception. Some users have reported engine-related problems that can impact performance and reliability.

A common issue is oil pump failure, particularly in models with Perkins engines. This problem can lead to severe engine damage if not addressed promptly. Symptoms include fluctuating oil pressure and the oil pressure light flashing on the dashboard. If you notice these signs, it’s crucial to stop operating the tractor immediately and have it inspected by a qualified technician.

Another engine-related problem is injector failure. This issue is more common in Tier 3 Perkins engines and can cause poor starting and engine knocking at low RPMs. Replacing faulty injectors can be expensive, costing around $450 per injector, with labor time ranging from two to four hours.

Some operators have also reported issues with the EGR (Exhaust Gas Recirculation) system. A common symptom is the check engine light coming on due to a bolt coming loose from the linkage between the EGR actuator and valve. Regular inspection of this component can help prevent unexpected breakdowns.

To minimize engine problems:

• Follow the recommended maintenance schedule rigorously
• Use high-quality fuel and oil
• Monitor engine performance and address any unusual sounds or behavior promptly
• Ensure proper air filtration to prevent contaminants from entering the engine

Transmission Problems

The Massey Ferguson 4707 comes with a 12×12 Synchromesh transmission, which is generally reliable. However, some users have experienced transmission-related issues that can affect the tractor’s operation.

One reported problem is difficulty engaging gears, especially when the tractor is cold. This issue can be caused by worn clutch components or improper adjustment of the clutch linkage. Regular maintenance and proper adjustment of the clutch can help prevent this problem.

Another transmission-related issue is the failure of the flywheel damper. This component typically fails between 4,000 and 6,000 hours of operation. Symptoms include a complete loss of drive and a banging noise from the bell housing. Replacing the damper costs around $350 for parts, with labor time being about a full day for an experienced mechanic.

To maintain transmission health:

• Change transmission fluid according to the manufacturer’s recommendations
• Avoid sudden gear changes, especially under heavy load
• Address any unusual noises or vibrations promptly
• Ensure proper clutch adjustment

Hydraulic System Issues

The hydraulic system is crucial for the operation of various implements, and problems in this area can significantly impact the tractor’s functionality.

Some users have reported hydraulic line coupler failures, particularly those connecting the rear of the tractor to the loader valve. This issue can often be traced back to improper tightening at the factory. Regular inspection of hydraulic connections and proper torquing can prevent fluid leaks and system failures.

Another common complaint is insufficient hydraulic fluid levels. Some owners have found that the factory-filled amount is not enough, leading to loader cavitation issues. It’s essential to check and maintain proper fluid levels, ensuring the sight glass shows at least 2/3 full when the system is cold.

To maintain hydraulic system health:

• Regularly inspect hydraulic lines and connections for leaks or damage
• Use the correct type and amount of hydraulic fluid
• Keep hydraulic couplers clean to prevent contamination
• Address any unusual noises or slow operation of hydraulic components promptly

Electrical System Problems

While the Massey Ferguson 4707’s electrical system is generally reliable, some users have encountered issues that can affect the tractor’s operation and starting ability.

A common problem is the failure of the Bottom Of Clutch Switch. This switch, located in the pedal box, can cause a loss of drive after the clutch pedal has been depressed. Symptoms may include an error code on the dashboard. Replacing the switch costs around $80 and is a relatively simple fix that doesn’t require additional programming.

Some operators have also reported starting issues related to the electrical system. These can be caused by weak batteries, corroded terminals, or faulty starter motors. Regular maintenance of the electrical system, including cleaning battery terminals and ensuring proper voltage, can prevent many of these issues.

To maintain electrical system health:

• Keep battery terminals clean and tight
• Check battery voltage regularly
• Inspect wiring harnesses for damage or loose connections
• Address any warning lights or error codes promptly

Brake and Steering Issues

The braking and steering systems are critical for safe operation, and problems in these areas require immediate attention.

Some users have reported brake disc wear, particularly in tractors that use a single-oil system for both transmission and brakes. If the brakes are worn down to metal, it can cause serious damage to the entire system. A blocked filter warning light can indicate that brake disc fibers are breaking down.

Steering issues are less common but can include excessive play in the steering wheel or difficulty turning. These problems can be caused by worn steering components or low hydraulic fluid levels.

To maintain brake and steering system health:

• Regularly inspect brake components for wear
• Avoid driving with the handbrake engaged
• Maintain proper hydraulic fluid levels
• Address any unusual noises or feelings in the steering system promptly
