A guidance system for a farming vehicle includes an electronic video camera attached to the underside of the farming vehicle and a video monitor electrically coupled to the camera for assisting an operator in steering the farming vehicle. The camera is mounted behind a front guide wheel of the farming vehicle for viewing the path traversed by the front guide wheel. The video monitor is mounted near the steering wheel by which the operator controls the front guide wheel in order to steer the farming vehicle. A safety guard/light housing is provided which prevents the camera from impacting the ground or obstructions which lie in the path of the front guide wheel. Lighting devices are incorporated within the safety guard/light housing for illuminating the area viewed by the camera. Side shields are also provided to form a viewing tunnel defining the area viewed by the camera.
