This potentiometer is a variable-resistance sensor that reports the position of a control lever or shaft to the tractor's electronic control unit. It is mounted within the electrical system and converts mechanical motion into a proportional voltage signal that the ECU uses to regulate hydraulic flow, engine speed, or implement response. A failing potentiometer produces erratic signal output, leading to jumpy actuator movement or a loss of function in the controlled circuit. The component is manufactured by AGCO to match the original housing geometry and wiper track profile, so the resistance curve across the full travel range replicates the factory calibration. No adjustment or shimming is needed during replacement; the connector locks into the harness and the mounting screws are tightened to the chassis ground.
