This manual provides comprehensive technical information, organized for ease of use, to help you maintain, diagnose, and repair your John Deere 9410, 9510, and 9610 Combines.

The John Deere 9410, 9510, and 9610 combines are powerful and versatile agricultural machines designed for efficient and high-capacity harvesting. These models, manufactured in the late 1980s and early 1990s, were renowned for their durability, performance, and advanced features. The 9410, 9510, and 9610 featured a range of engine options, including the powerful John Deere 6090 engine rated at 240 horsepower, the 6096 engine rated at 280 horsepower, and the 6090 engine with a turbocharger rated at 300 horsepower. These engines were paired with robust transmissions, including the Powr-Shift 4-speed transmission and the optional 5-speed transmission, providing smooth and efficient power delivery.

The 9410, 9510, and 9610 combines were equipped with various features to enhance performance and operator comfort. These features included a spacious cab with excellent visibility, adjustable seats, and ergonomic controls. The combines were also equipped with advanced hydraulic systems, including the exclusive John Deere "Power-Shift" system, which allowed operators to change gears on the go without sacrificing power. The 9410, 9510, and 9610 models were also equipped with a variety of cutting-edge features, including a "rotary header" for efficient grain gathering, a "sieve system" for effective grain separation, and a "cleaning system" for optimal grain purity. These features ensured maximum harvest output and minimized crop losses.
