Double Gears For John Deere Combines allow you to change the direction and speed of the combine output shaft. These gears are typically replaced when worn or damaged. The gear train is comprised of a main disk with teeth that mesh with another gear wheel.
The main gear also has a central hole with splines for attachment to the intermediate shaft. In addition to the gear train, John Deere combine combines also feature variable speed drive systems. The variable speed drive system can be configured to shift automatically between two speeds, allowing the operator to choose the speed to suit the conditions of the field.
PBST is similar to a manual shift three-speed transmission. The difference between PBST and a traditional three-speed transmission is that the PBST doesn't have a shift lever. Instead, the operator must stop the combine before shifting. When the combine is stopped, the operator simply pushes a button to select the desired gear. The desired gear selection is displayed on the digital cornerpost display. Within the gear range, the combine can change speeds infinitely.
The S Series combines are also equipped with built-in technology that senses potential problems and sends an alert to the dealer.These combines can monitor fuel levels, location history, and in-cab displays.
