More Information
Summary:An agricultural implement includes an electrically conducive ground engagement tool with an opening and a sensor having a first and second conductor. An insulative material extends around a periphery of the opening to a contact area, and a conductive material fills the opening and extends to the contact area to electrically couple the conductive material to the ground engagement tool. The first conductor electrically couples to the conductive material, and the second conductor electrically couples to the ground engagement tool. A controller may receive a signal from the sensor indicative of an electrical resistance between the first and second conductors, determine the ground engagement tool has worn past a threshold amount in response to receiving the sensor signal indicative of the electrical resistance being above a threshold value, and output an output signal in response to determining the ground engagement tool has worn past the threshold amount.
