Features and Benefits

  • Combines the advantages of AutoTrac and mechanical row feelers
  • Improves yield quality
  • Reduces operator fatigue


  • MANUFACTURER: John Deere
  • MODEL: AutoTrac RowSense System


  • AutoTrac RowSense System combines the advantages of the AutoTrac System along with mechanical row feelers. This systems eliminates the limitations of a single system when harvesting corn. Productivity and precision in any conditions: down crop, curves and unevenly shaped fields.
  • Operators have become accustomed to experiencing the benefits of AutoTrac when operating John Deere equipment. However, when operating in standing corn, different situations may limit the performance of AutoTrac. These conditions might include:
  • Crops planted without AutoTrac
  • Unavailability of guidance lines from planting
  • GPS drift from year to year when using SF1 or SF2 corrections
  • Planter drift in adverse terrain
  • In these situations, AutoTrac RowSense is the perfect option to experience the benefits of AutoTrac in application operations and harvesting operations in standing corn.
  • AutoTrac RowSense utilizes a row sensor to accurately detect the corn rows and guide the vehicle down the row. When used while harvesting, operators can benefit from reduced fatigue, better efficiency in lodged corn, more consistent operating speeds, and reduced header loss. During spraying, operators can experience reduced fatigue, less crop damage, and higher operating speeds when compared to manual driving.
  • In areas where corn plants are missing, such as waterways, wash outs, or flooding, GPS fusion  enables the system to switch to GPS-only guidance until the row sensors can detect rows again. This feature keeps the vehicle on the correct pass regardless of the condition of the crop in the field. GPS fusion, an industry exclusive feature of RowSense, ensures that the operator experiences the benefits of AutoTrac in a wider variety of field conditions.

Down Corn:

  • When operating in AutoTrac RowSense mode, both systems - row feeler and AutoTrac - are active. As soon as the feelers are unable to deliver a reliable signal, AutoTrac System takes over control of the steering. The system switches immediately back to fused mode when a row signal is available.


  • When selecting "A-B curves" or "Adaptive curves" in the guidance settings, AutoTrac RowSense System reacts proactively when approaching curves in the field. The combine steers smoothly into the curve as the location and radius is already available from the last path.
  • Field not planted using AutoTrac System: 
  • Until now it was not possible to utilize AutoTrac System in  fields planted without the use of guidance assistance, because of the differing track spacings caused by manual steering. AutoTrac RowSense System is able to self-centershift using information from the mechanical row feeler. With this functionality the combine will still follow the rows  accurately, even if the tracks in the field are not parallel.

Headland Turns:

  • During headland turns, AutoTrac RowSense System provides the same functionality as AutoTrac.
  • Activating the system on the headland will guide the combine accurately into the rows, utilizing the full working width. This is of particular importance while operating a row dependent cornhead.


  • The AutoTrac RowSense activation is required to run both AutoTrac RowSense and AutoTrac Vision on sprayers. See the AutoTrac Vision/RowSense pages for information on how those systems operate on sprayers.
