Engine and Performance Details of the S660 Combine

The S660 John Deere combine is powered by a 6.8L 6-cylinder PowerTech™ Plus engine. It delivers an impressive 205 horsepower, providing the necessary power to handle large-scale harvesting tasks. With this engine, the S660 combines strong performance with fuel efficiency, allowing operators to maximize their output during long working hours.

The engine is paired with a variable-speed fan system, which optimizes cooling for consistent engine performance. This ensures reliable operation even in high-demand conditions, reducing the risk of overheating. The engine is also equipped with an integrated air filtration system to improve longevity and minimize maintenance needs.

For added operational flexibility, the S660 features a hydrostatic transmission, which provides smooth power delivery and enhanced control over the harvesting process. The combination of the engine’s power and the advanced transmission system results in superior fuel economy and lower operating costs, making it an ideal choice for both small and large-scale operations.

The performance of the S660 is further enhanced by its intelligent harvesting systems. With automatic adjustments to engine load and speed, the combine adapts to varying crop conditions, ensuring optimal harvesting performance across different field types. This leads to improved productivity and a higher-quality end result.

Harvesting Capacity and Efficiency Features

The S660 John Deere combine delivers a high harvesting capacity with a 300-bushel grain tank, allowing longer periods of operation before unloading is required. The grain tank unloads at a rate of 3.1 bushels per second, reducing downtime during the harvest process.

Equipped with a 9.0L PowerTech™ engine, the S660 offers ample horsepower to tackle large-scale harvesting tasks. The combination of this engine and the hydrostatic transmission guarantees smooth acceleration and consistent power, even during demanding harvesting conditions.

The 640R header increases cutting efficiency with a wide cutting width, enabling the machine to cover more ground in less time. It operates at high speeds while ensuring clean and precise cuts, optimizing crop flow into the feeder house.

Automatic header height control adapts to terrain changes in real-time, minimizing crop loss. The ActiveTerrain™ technology further enhances performance by improving ground contour following, ensuring that harvesting continues smoothly, regardless of field conditions.

The CommandARM™ console provides operators with intuitive controls, while the GreenStar™ display offers real-time data on the machine’s performance. These features enable quick adjustments for maximum operational efficiency, allowing the operator to focus on productivity.
