AutoTrac™ assisted steering system

The 70 Series Combines offer the latest in automated smart technology that delivers top harvesting performance in most crops and conditions. Factory-installed GreenStar™ AutoTrac is an assisted steering system that automatically steers the combine through the fields while harvesting.
 
All 70 Series Combines (PIN 730101 and up) come from the factory AutoTrac Ready. This means the electrical harnessing and electrohydraulic steering components required for AutoTrac guidance are in base equipment and, therefore, conveniently installed at the factory.
 
The GreenStar AutoTrac steering system utilizes STS™ Combine electrohydraulic steering components as well as the common GreenStar components (optional) to provide full auto-steering capability.
The following optional GreenStar common components are required for functionality of AutoTrac on the S-Series Combines:
  • StarFire™ 3000 or StarFire iTC Position Receiver
  • GreenStar 3 (GS3) 2630 Display, GS3 Command Center Display, or GreenStar 2 (GS2) 2600 (GS2) Display
  • AutoTrac™ display activation
The following optional GreenStar common components are required for functionality of AutoTrac on the STS Combines:
  • StarFire  iTC Position Receiver
  • GS2 2600 Display or Original GreenStar Display
  • Mobile Processor
  • AutoTrac KeyCard
AutoTrac combine-specific components (base equipment)
 
The 70 Series Combines require the following steering components for operation of the AutoTrac steering system in base equipment:
 
The steering system unit (SSU), located under the cab, takes information from the GreenStar components and provides signals to the electrohydraulic valve to guide the combine.
 
The electrohydraulic steering control valve regulates oil flow to the steering cylinders responsible for adjusting the combine's direction of travel. This valve does electronically what an operator does manually to steer the combine.
 
The SSU needs to know the exact position of the steering cylinders when making a turn. The wheel angle sensor provides this information to ensure proper turning.
 
The remaining component, the steering-wheel position sensor, alerts the system when the operator wishes to resume control. The sensor detects when the operator rotates the steering wheel just a few degrees. Also, if the operator leaves the seat, the SSU shuts off the electronic part of the steering control valve. When using the required GreenStar display, an alert tone is sounded and the display icon turns off when AutoTrac is disengaged, indicating manual operation is required.
NOTE: Field-installed bundle attachments for the AutoTrac combine steering component only are available for 50 and 60 Series Combines.
 
IMPORTANT: GreenStar AutoTrac for combines is an assisted steering guidance system. The operator is responsible for turning the combine at the end of each pass as well as steering around any field obstacles such as trees and waterways that may be encountered in the middle of a pass. The operator can always regain control of the combine steering by simply turning the steering wheel.
RowSense™ for corn harvest
 
An AutoTrac solution is also available for corn. 
 
AutoTrac RowSense for combines offers operators the same high-level performance and productivity during corn harvest that they have experienced in other crops or with their AutoTrac-equipped tractors and self-propelled sprayers at other times of the year.
