AL155986 Rotary Position Sensor Replacement for John Deere Tractor 6090M 6105R 6150M 6155R 7230R 6420 6020 Steering Angle Sensor

Product Overview The AL155986 Rotary Position Sensor is a premium, high-accuracy electronic monitoring component explicitly engineered for John Deere Agricultural Tractors and Industrial Powertrains. Operating based on advanced Hall-effect technology, this versatile 3-pin sensor detects precise real-time angular positions, rotary movements, or steering angles. It streams stable analog telemetry pulses directly to the tractor’s main Electronic Control Unit (ECU). Whether managing hitch linkages, cabin suspension tracking, or steering calibration systems, this ruggedized component ensures perfect equipment responsiveness and prevents fault codes, making it an essential replacement part for modern precision farming operations.

Precision Signal Tracking: Resolves common dashboard issues such as intermittent hydraulic linkage dropping, AutoTrac steering alignment drops, or active “Position Sensor Signal Out of Range” trouble codes. Easy Direct Fitment: Built to exact original factory dimensions (AL155986) with a standardized double-D shaft interface for quick, bolt-on, plug-and-play maintenance. Cross-Reference Guide This sensor interchanges with the following original and aftermarket part numbers: JOHN DEERE: AL155986 AGRICULTURAL ELECTRONICS: Premium high-durability electrical components engineered to match factory John Deere instrumentation requirements Maintenance Tip: If your John Deere 6150M or 6105R Tractor triggers an active steering angle code, fails to engage its automatic guidance system, or struggles to maintain a consistent rear hitch depth, check the AL155986 sensor. Because it tracks mechanical pivoting, verify that the double-D shaft connection is aligned correctly and free from packed farm grease or moisture seepage inside the 3-pin harness plug before bolting down this new replacement unit.
