Abstract
A distance measuring device mounted to a planter used to plant crops. The distance measuring device has a cable extending between a first pulley and second pulley wherein the cable has at least one target. A sensor located adjacent the first pulley and connected to a controller sends a signal to the controller when the sensor detects the target. Adjacent the second pulley is an encoder that sends a second signal to the controller based upon the rotation of the second pulley such that the controller can determine the amount of distance that the planter has traveled.
