FieldCruise™
All 7R, 8R and 9R Series Tractors feature FieldCruise for excellent control of working speeds below full engine load or full throttle position.
  • With the throttle control fully forward, FieldCruise can be set in the CommandCenter™ and allows setting an upper limit to engine speed. It is adjustable from 1100 rpm to 2210 rpm.
  • When FieldCruise is used, the engine responds to small variations in load.
  • FieldCruise maintains a constant engine speed, thus constant ground speed as the load on the tractor varies. This is especially useful during lighter load operations, such as chemical incorporation, fertilizer applications, and seeding when maintaining a constant speed is critical to application rates.
  • Operating with FieldCruise in these applications also improves fuel economy by keeping the engine speed at a lower level.
Setting FieldCruise
 
The CommandCenter is used to adjust the desired FieldCruise maximum engine speed setting.

Activating FieldCruise is simple:
  1. Press the engine shortcut key located on the CommandARM™.
  2. When the engine page appears on the CommandCenter display, select the FieldCruise icon (soft key G). This enables FieldCruise by checking the activation box.
  3. Select the soft key indicator (soft key F) located on the CommandARM.
  4. Rotate the thumbwheel clockwise to increase engine speed or counterclockwise to decrease the FieldCruise speed setting.
Engine power bulge and FieldCruise
 
When operating with FieldCruise enabled, the tractor only has an available power bulge amount for the actual engine speed setting. If the setting were at 1950 rpm down to 1100 rpm, the engine would have a declining amount of power bulge available. Therefore, in heavy tillage applications or other operations that require maximum engine speed or power, FieldCruise should be disabled or reset to the maximum engine speed.
