One of the key features of the S790 is its fuel efficiency. The combine’s improved systems, including the belts, transmission, residue system, rotors, and lower RPM, contribute to its overall fuel efficiency.

Compared to the X9 1100 model, the S790 uses up to 20% less fuel per tonne harvested, helping keep input costs low for farmers.

The S790 is also notable for its size and capacity. It can hold up to 400 bushels of grain, with an unloading rate of 3.8 bushels every second.

Its total cleaning area is an impressive 9145 square inches, making it a highly efficient machine for large-scale harvesting operations.

In terms of automation, the S790 is a leader in its class. It comes equipped with the Combine Advisor package, which automatically adjusts the combine’s harvest settings to ensure higher quality grain in the tank and reduce the chance of grain loss.

Cameras on the clean grain and tailings elevator provide valuable information to help operators make informed decisions about the crop flow.

The S790 also boasts advanced data-sharing capabilities. With JDLink connectivity, yield maps, and other harvest data can be sent to the Operations Center for later analysis.

This allows farmers to view, analyze, and compare different map layers, print out reports, and make more profitable decisions for future harvests.

Despite its power and size, the S790 is designed with operator comfort in mind. The cab offers a comfortable and easy-to-operate environment, ensuring operators can work long hours without fatigue.

The machine’s design also prioritizes safety, with features like the modulated feeder house reverse that reduces the chance of plugging in heavy crops.
