What to Expect from the John Deere S690 Combine?

The S690 is the largest model in the John Deere S-Series combine harvester range. It outranks the S680 with greater horsepower and a larger clean grain system.

This combine harvester is best suited to agricultural harvesting of wheat, rice, barley, oats, peas, soya, canola and maize. The high performance of John Deere’s S-Series combines boils down to the front-end equipment that has greater harvesting capacity than earlier models thanks to the 14,100 L grain tank.

So, if you’re looking for a machine suited to large commercial-scale harvesting, the S690 is a combine to seriously consider.

Things to Consider

As with every machine, there are things to note, including:

  • Expense—as mentioned, the S690 is more expensive to buy than previous models. Used models go for anywhere from $260,000 to $460,000. So, it’s important to consider whether you need the new technology.
  • Tech maintenance—with newer technology comes regular maintenance and the possibility of downtime when problems do occur. If the tech does play up, you will require a diagnosis and often re-calibration to get things back up and running.
  • Loud cab—According to anecdotal feedback, the cab is louder than other models and brands of combine harvester, which can be a dealbreaker for some.
  • High fuel consumption—some users note that the S690 has a high fuel consumption rate, but it’s impossible to know what circumstances operators experienced to cause this.
