From the article, "Every time the sensor blew, the onboard computer would shut the tractor down. It takes a technician at least two days to order the part, get out to the farm, and swap out the sensor."
This is just a guess since that passage is vague, but it sounds to me like he isn't able to order the part himself. It might be a proprietary thing that only a (John Deere approved) tech can order. Either that, or maybe he isn't able to overcome some kind of anti-tampering hardware to install it himself.
- bri3d 12y agoA 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.
