2011 John deere 333D - seller installed new 18" camoplast tracks 1594.02 "Left SPeed Sensor - Bad or erratic Data" 1595.02 "Right SPeed Sensor - Bad or erratic Data" Any words of wisdom other than "go to service rep"?
The speed sensors are on the back side of the drive motors, they have a short pigtail and plug into the main harness. Don't know why the mechanics would be in that area changing tracks but you never know. Might just be unplugged, or they damaged the harnesses?
