Abstract: A hitch for a beet harvester including a hitch frame traversing the entire width of the harvester with outer ends connected to the harvester frame, a transverse beam with obliquely forwardly extending side portions affixed together at an apex located intermediate the ends of the hitch frame, a hitch bar extending forwardly from the apex of the transverse beam and being pivotally connected to the hitch frame adjacent said apex, the front end of the hitch bar being adapted for connection to the drawbar of a tractor, and a steering cylinder pivotally connected to the hitch bar well rearwardly of the apex of the transverse beam and also pivotally connected to one side portion of the transverse beam.

Abstract: A positioner for automatically positioning a farm implement, such as a sugar beet harvester, in line with rows of crops such as sugar beets and for automatically maintaining the height of the implement relative to the ground surface. The positioner includes a harness pivotal about an upright axis, and a pair of crop and ground level sensing shoes mounted to the harness pivotally to permit the trailing ends of the shoes to swing vertically and horizontally. Hydraulic controls respond to swinging of the shoes vertically (as when the height of the implement varies) and horizontally (as when the implement strays toward one side or the other of a crop row) and return the implement to its correct vertical and side-to-side alignment with the crop row.
