Abstract

A work vehicle includes a chassis, and a work implement movably coupled to the chassis and configured to perform a field-engaging function. The work machine also includes an actuator coupled to the work implement and configured to adjust a position of the work implement relative to a ground surface. The work machine further includes a controller in communication with an output device and a communication module. The controller is configured to monitor a location of the work machine via the communication module. The controller is also configured to load a field map from a field map database, the field map identifying at least one impact event comprising a geotagged location. The controller is further configured to display an alert via the output device in response to the location of the work machine approaching within a predetermined distance from the geotagged location.
