Machine Tracks Crooked / Two-Speed Disabled

Diagnosis & fix steps

LOGIC: Left Drive Motor Wheel/Track Speed Sensor Signal Missing. ACTION: Disconnect Hall-effect speed pickup at the left final drive motor housing. Measure 5V reference supply and ground; inspect sensor harness running along the track frame for rock impact or brush snags.

Red Seal field insights

Brush Snag Damage: Operating in heavy brush or rocky land-clearing pushes debris between the track frame and chassis, ripping the exposed rubber pigtail straight out of the drive motor housing.
