Abstract
A work machine includes a frame assembly supporting an idler and a drive sprocket. A track is looped around the idler and the drive sprocket. A track-adjust mechanism is configured to extend and to retract the frame assembly to adjust a tension of the track. A position sensor is configured to measure an extension of the track-adjust mechanism. A controller is configured to receive an extension measurement from the position sensor, determine a track tension based on the extension measurement, and output a track tension signal.
