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.
