TrueTracker implement steering sytem

  • Allows the implement to correct its position without input from the tractor
  • Utilizes terrain compensation technology for high accuracy on difficult terrain
  • Requires a GNSS antenna and NavController II on your implement and Autopilot™ system and the FmX® display in your tractor
  • Ideal for row crop and multiple-pass farming applications

  • Overview

  • Implement Control Comparison

  • Compatible Products


Keep your implement and tractor on the same guidance line with the Trimble® TrueTracker™ implement steering system, an active implement guidance system that allows your implement to guide itself independently from your tractor.

TrueTracker uses your tractor's Autopilot system to monitor your implement and signal it to follow the correct path during periods of drift. TrueTracker keeps you confident that your implement is on line all the time.

  • Accurately steer your implement and tractor on a repeatable path
  • Operate in the most difficult terrain and variable soil conditions
  • Minimize draft and result in more consistent guess rows
  • Reduce crop damage and compaction
  • Improve seedbed and nutrient placement

Terrain Compensation Technology

TrueTracker utilizes T3™ sensors on the NavController II to calculate the actual position of the vehicle to help minimize skips and overlaps in areas with rolling terrain, slopes, and rough ground.
