A lot of German cars have "coded" sensors and modules, where the sensor's serial number is written into protected storage somewhere and a mismatch will disable functionality. In some cases it makes sense (for example, if special calibration data needs to accompany the sensor) but it's often implemented simply to make replacement require a factory technician. I wouldn't be surprised if Deere have gone the same route.
