2015 John Deere S680 Combine Harvester Detailed Specifications

Choose the 2015 John Deere S680 for its 13.5-liter PowerTech PSS engine delivering 473 horsepower under standard load and up to 530 horsepower with power boost. This six-cylinder diesel engine features a high-pressure common rail fuel system for stable combustion and reduced fuel usage during long harvesting hours.

Rely on the 400-bushel grain tank, which unloads at a rate of 3.8 bushels per second through a 22.5-foot unloading auger. The machine uses an STS single-tine separation rotor with a 30-inch diameter, providing precise threshing and smooth material flow even in damp crop conditions. Active Concave Isolation helps maintain uniform clearance, reducing grain loss and improving sample quality.

Take advantage of the Dyna-Flo Plus cleaning shoe with a total cleaning area of 7900 square inches, ensuring consistent separation in high-yield fields. The feederhouse includes a heavy-duty drive and a variable speed reverser for smooth header control. Operators can manage all systems through the CommandTouch display with integrated yield mapping and AutoTrac guidance for consistent cutting accuracy.

Expect a transport weight of approximately 39,000 pounds with dual front wheels for better stability and flotation. Hydraulic four-wheel drive is available as an option for improved traction on soft ground. The fuel tank holds 330 gallons, allowing extended work time between refills. Maintenance is simplified with grouped service points, automatic greasing, and remote oil checks.

Engine Power Output, Fuel Capacity, and Emission Standards of the 2015 S680

The 2015 John Deere S680 uses a 13.5-liter PowerTech PSS engine delivering 473 horsepower at rated speed, with a maximum boost up to 543 horsepower for heavy load conditions. This power level supports consistent threshing and separating performance, even in high-yield crops or challenging terrain.

The fuel tank holds 330 gallons, allowing long operational hours without frequent refueling. Pairing this capacity with the 23.1-gallon DEF tank ensures stable operation under Tier 4 Final emissions compliance. Plan for refueling intervals based on average fuel consumption of 1.2 to 1.5 gallons per acre, depending on crop type and field conditions.

The engine meets strict Tier 4 Final emission standards by using a combination of cooled exhaust gas recirculation, selective catalytic reduction, and a diesel oxidation catalyst. This system reduces nitrogen oxides and particulate matter while maintaining optimal fuel economy. Use ultra-low sulfur diesel to protect the emission components and maintain reliability during peak harvest periods.

Grain Handling Capacity Cleaning System and Separator Features Overview

Choose the 2015 John Deere S680 for a grain tank capacity of 400 bushels, enabling longer harvesting intervals without frequent unloading. The unloading auger operates at 3.8 bushels per second, reducing downtime and maintaining a steady workflow during peak harvest hours.

Rely on the DynaFlo Plus cleaning system for precise grain cleaning with a 28% larger sieve area compared to earlier models. Adjustable fan speeds from 620 to 1,350 rpm help maintain consistent cleaning even under varying crop conditions. Use the active tailings return system to reprocess unthreshed material, improving overall grain quality.

Optimize throughput with the TriStream rotor that measures 30 inches in diameter and provides a separation area of 3,713 square inches. The concave design ensures gentle handling of grain while maintaining high separation efficiency. Combine these features to achieve reduced grain loss and improved productivity across diverse crop types.

Cab Comfort Control Technology and Maintenance Access Points

Adjust the climate system directly from the CommandARM console to maintain a stable temperature during long harvesting sessions. Use the automatic air recirculation mode to reduce dust ingress and improve cabin air quality. Activate the seat suspension system to minimize vibrations and operator fatigue, ensuring consistent comfort throughout the day.

Optimize control with the ergonomic joystick layout that integrates header, unloading auger, and threshing adjustments. The multi-function display provides quick access to diagnostic data, reducing downtime caused by unnoticed malfunctions. Customize lighting from the overhead panel for better visibility during night operations.

Access maintenance points without tools using the wide-opening side panels. Grease zerks are grouped in central locations, reducing service time. Inspect the cooling package by sliding out the radiator screens for easy cleaning. Replace the cabin air filter via the right-side compartment without removing additional covers.

• Check hydraulic fluid levels through external sight gauges to avoid unnecessary disassembly.
• Use the ladder-mounted service platform for safe access to engine and grain tank components.
• Monitor belt tension and wear via clear inspection windows on key drive housings.
• Drain fuel and oil using integrated quick-release valves positioned near ground level.

Follow the operator manual schedule for lubrication and component checks to extend service intervals. Perform daily visual inspections of belts, hoses, and electrical connections through strategically placed access hatches. Keep the cabin electronics compartment sealed to prevent dust accumulation and sensor malfunctions.
