Caddy with guidance system for agricultural implements

摘要

A caddy with a guidance system for towing agricultural implements is provided for row crop farming. The caddy converts mounted agricultural implements to pull-type implements, allowing larger implements to be pulled by relatively small tractors. A guidance system automatically maintains the desired position of the implement and the caddy with respect to the crop rows. The frame assembly of the caddy includes a tongue assembly for attachment to a tractor. The tongue is pivotally connected to an axle which is rotatable about a vertical axis at the rear of the caddy. A three-point hitch is provided in association with the axle of the caddy for attachment to a mounted implement. The guidance system of the invention is provided as a sensor-activated hydraulic mechanism having at least one hydraulic cylinder to rotate the axle about the vertical axis to steer the caddy and provide the necessary correction to its path of travel.
