An agricultural implement includes: a frame; a location sensor coupled to theframe; aplurality of shank assemblies carried by the frame that each include a shankand a trip sensorassociated with the shank; and a controller operatively coupled to a memorystoring a field maptherein, the location sensor, and the trip sensor of each of the shankassemblies. The controllerreceives an output trip signal from a trip sensor; determines a specific shankassociated with thetrip sensor that output the trip signal; determines a separation distancebetween the specific shankand a reference; determines a current location based on a current locationsignal from thelocation sensor; determines a field object location based on the determinedseparation distanceand the determined current location; and outputs an update signal to thememory to designate thefield object location on the stored field map.
