Whether you're looking to buy a used John Deere 850 or you already own one, understanding its features, common issues, and maintenance needs can greatly extend its lifespan and improve performance.
Overview of the John Deere 850
The John Deere 850 is a compact utility tractor designed for a wide range of applications, from landscaping to farming. It was first introduced in the 1980s and gained popularity due to its reliability, ease of use, and impressive versatility. The 850 is part of John Deere’s 800 series, and it’s known for its fuel efficiency, rugged construction, and ability to handle various attachments.
Key Features
The 850’s design allows it to perform exceptionally well across a variety of environments. Here are some of the most common uses:
While the John Deere 850 is generally reliable, like any piece of equipment, it is not immune to issues. Some common problems that owners may encounter include:
1. Starting Problems
One of the most frequently discussed issues with the 850 is starting trouble. Whether it’s a dead battery, clogged fuel filter, or a faulty starter, starting issues are common in older models. Regular maintenance of the battery, fuel system, and starter components is essential to avoid these problems. If the tractor won’t start, it's worth checking the battery charge and the condition of the fuel lines.
2. Transmission Issues
Over time, transmission problems can occur, especially if the tractor is used heavily. The John Deere 850’s 8-speed transmission can wear out, especially if the fluid levels are low or the fluid hasn't been changed regularly. It’s important to check transmission fluid levels frequently and replace the fluid at recommended intervals.
3. Hydraulic System Failure
The hydraulic system in the 850 can be prone to leaks or power loss over time. Hydraulic seals can wear out, and hydraulic fluid can become contaminated, causing power loss or erratic behavior in the attachments. Regularly checking and replacing hydraulic fluid and seals will prevent most hydraulic system problems.
4. Engine Performance Issues
Over time, the engine in the 850 may experience reduced power or efficiency. This is often due to a clogged air filter, old fuel, or injector issues. Ensuring that the air filter is clean and replacing the fuel filters regularly can help maintain engine performance. Additionally, a diesel engine additive might help clean the fuel system and improve power output.
Maintenance and Care for the John Deere 850
Regular maintenance is the key to keeping the John Deere 850 running smoothly. A well-maintained tractor not only performs better but also lasts longer, giving you a better return on your investment. Below are some tips for maintaining your 850:
1. Regular Fluid Checks
Ensure that the engine oil, hydraulic fluid, and transmission oil are checked regularly. The John Deere 850 uses a diesel engine, which needs high-quality diesel oil to operate efficiently. Regularly changing the fluids and filters (oil, fuel, air) will keep the engine running clean and improve its lifespan.
2. Clean the Air Filter
The air filter on the 850 is critical for preventing dirt and debris from entering the engine. A clogged air filter can decrease engine performance and fuel efficiency. It’s important to check the air filter regularly and replace it when necessary.
3. Inspect the Fuel System
The fuel system in any diesel engine should be inspected frequently for signs of contamination, clogs, or leaks. Replacing fuel filters every season or as recommended by the manufacturer ensures clean fuel flows to the engine, preventing wear and tear on the fuel injectors.
4. Grease Moving Parts
Regularly greasing the moving parts of the John Deere 850, including the loader arms and tractor joints, ensures that they move smoothly and efficiently. This prevents unnecessary wear and extends the life of these components.
5. Battery Maintenance
As with any heavy equipment, maintaining the battery is vital. Clean the battery terminals and check the charge regularly. If the tractor has trouble starting, it might be time for a new battery or a check-up on the electrical connections.
Conclusion: John Deere 850’s Legacy in Compact Tractors
The John Deere 850 stands as a reliable and versatile machine for a variety of applications, from farming to construction and landscaping. With its robust engine, impressive lift capacity, and compact size, it remains a favorite among small-scale contractors, farmers, and landscapers who need a powerful yet nimble piece of machinery.
By understanding common issues, maintaining the tractor regularly, and addressing problems early, owners can maximize the life and efficiency of their John Deere 850. Whether you’re troubleshooting engine performance or keeping an eye on fluid levels, taking proactive care of your equipment can ensure that it continues to serve you for years to come.
As John Deere continues to evolve its range of products, the 850 remains a testament to the company’s long-standing commitment to providing high-quality, durable machines that can handle the toughest tasks with ease.
