Good To Know
Q: What does this potentiometer sensor do on a planter? A: It senses the position of a mechanical component, such as a linkage or arm, and sends a proportional electrical signal to the tractor or planter's monitoring system.
Q: Can I use this sensor on any row unit? A: This sensor is designed to fit the specific John Deere DB series planters listed, so it is best to confirm your model and row unit type before purchasing.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
