Hydraulic System and Features
The 8820 John Deere combine features a highly reliable hydraulic system designed for optimal performance and smooth operation. It utilizes a closed-center, load-sensing hydraulic system that ensures precise control under varying load conditions.
The system includes multiple hydraulic pumps, offering a combined flow rate that supports efficient operation of essential functions, such as the header, drive systems, and unloading auger. The main pump delivers up to 80 gallons per minute (302 liters per minute) of hydraulic flow, enabling swift adjustments during harvesting tasks.
The hydraulic pressure relief valves are set to ensure system safety and prevent damage in case of unexpected load spikes. This pressure is typically set to 2,500 psi (172 bar), providing enough force for heavy-duty tasks while maintaining protection for sensitive components.
The 8820’s hydraulic system also incorporates multiple quick-connect fittings, reducing downtime during maintenance and ensuring a smooth replacement of hydraulic hoses or components. Routine checks and proper lubrication are crucial for maintaining long-term efficiency.
For ease of operation, the hydraulic system integrates well with the combine’s electronic controls, allowing for automated adjustments during operation. This reduces the need for manual input and provides a seamless experience for the operator.
Regular maintenance, including checking fluid levels and inspecting hoses for wear and tear, will keep the hydraulic system running at peak performance for years. Use only John Deere-approved hydraulic fluids to avoid potential damage and ensure the system’s longevity.
Maintenance and Service Intervals
Regular maintenance ensures optimal performance and longevity of the John Deere 8820 combine. Adhere to the following intervals for efficient operation.
Change engine oil every 250 hours of operation. Use high-quality oil to maintain proper engine function and prevent excessive wear.
Replace the fuel filter at 500 hours. Clean the air intake filter every 100 hours or more frequently in dusty conditions to avoid engine strain.
Inspect the hydraulic system every 500 hours. Replace hydraulic fluid as necessary to ensure smooth operation of all hydraulic components.
Grease all pivot points and drive components every 50 hours or as recommended by the user manual. This prevents friction and prolongs part life.
Check the condition of the combine’s belts every 100 hours. Replace any belts showing signs of wear or cracking to avoid unexpected breakdowns.
Inspect and clean the cooling system after each harvest season. Ensure all radiators and cooling elements are free from debris to maintain efficient heat dissipation.
Monitor tire pressure regularly and check for any signs of wear or damage. Tire replacement or rotation should occur when needed to ensure proper traction and load distribution.
It’s advised to perform a complete inspection at the start and end of each season. This should include checking all fluid levels, belt tension, and component integrity.
Adhering to these intervals reduces the likelihood of downtime and increases the combine’s operational efficiency.
