Which John Deere combine is right for your operation?

John Deere offers a wide range of combine models so you can choose what is best for your operation. Look at the differences between S- and X-Series Combines, and the models available in each series, so you can determine which one is right for you.


John Deere S770 and S780 Combines


How are Combines Used for Harvesting Crops?

Originally, combines were designed to harvest wheat. Over time they began to be used for other crops such as corn, soybeans, rice, oats, rye, barley, sorghum, flax, and more. Combines have a binder-type cutting device that takes the grain from the cutting head to the threshing machine that is designed to work as it moves across the field. Combines are used once the crops are fully grown and ready to be harvested. With several combine options available through John Deere, it is important to understand the differences and pick the one that is right for your operation.


S-Series Combines

Equipped with fully integrated technology, S-Series Combines are designed to adjust for changing conditions even when you can’t see them. This means that no matter the field conditions, and whether you have a new or seasoned operator, you can expect consistent grain quality.

John Deere S-Series Combines include several standard features that make your harvest more comfortable and efficient.

  • The Generation 4 4600 CommandCenter Display is great for all operators with intuitive screens and customizable shortcut buttons.
  • The ActiveYield system eliminates the need for manual calibrations which take your valuable time. ActiveYield automatically calibrates the weight of the grain while you are running, resulting in highly accurate field documentation.
  • The Deluxe Cab is spacious and comfortable and provides optimum visibility.
  • S-Series Combines come with JDLink and 5 years of service, giving you easy access to your agronomic data at no initial cost. With JDLink, you can access data from anywhere and easily share it if needed to make real-time decisions.
  • John Deere Operations Center puts your yield data at your fingertips while organizing it in an easy-to-understand format. Turn your data into usable information that will help to improve your harvest year after year.
  • Data Sync automatically sends data directly to Operations Center so you don’t have to wait for manual data uploads to start analyzing.
  • John Deere Connected Support lets you receive alerts of potential machine issues before they happen. You can also decide to send alerts to your dealer, to prepare them to perform needed maintenance and drastically reduce your downtime during harvest.


What S-Series Models Are Available?

In 2012, John Deere launched the S-Series Combines, and they have been harvesting fields ever since.
