Abstract
A tractor-planter guidance aid system including a TV camera mounted on a servo motor at an end of the planter to view a mark in the terrain created by a marker mounted on the other end of the planter. Angle sensors send signals to a control circuit, these signals representing the angle between the tractor and the planter and between the camera and the planter. The control circuit cooperates with the servo motor to maintain the camera in parallel alignment with the tractor. A TV monitor displays the image detected by the camera to the operator of the tractor.
