Abstract: A root crop harvester has a lifting device picking up a mixture of crop and admixtures. Screening belts downstream of the lifting device transport the mixture away from the lifting device. A feed belt feeds the mixture to a sorting zone where a separating device is arranged above the feed belt. A sorting belt is arranged downstream of the separating device that has first and second stripper belts circulating in a stripping direction and provided with stripper elements. The stripper elements act on the crop transverse to a feed direction and supply the crop to the sorting belt. The admixtures remain on the feed belt and are discharged in a guiding direction angled to the stripping direction. At least one of the stripper belts has a discharge section with an incline smaller than 55° relative to the stripper plane and has in sections a non-round contour and a constant incline.

Abstract: A farm tractor field stone collection implement is provided with a forward dragbox section having open forward and aft ends, a perforated bottom, multiple spaced-apart teeth projected forwardly and downwardly from the section leading edge, and hitch points for coupling to a farm tractor implement hitch accessory, with an aft dragbox section having a forward open end aligned with the forward dragbox section open aft end, a perforated bottom, and an aft end from which collected field stone may be dumped, with a vibrator mounted on the forward dragbox section, and with fasteners joining the forward and aft dragbox sections in an articulated manner relative to each other.

Abstract: A tomato harvester of the type having a main frame and acting to sever the tomato plants below ground and to pick up and elevate them to a tomato separator for separating the tomatoes from the vines. A low elevator segment is separated from an upper elevator segment to provide a gap between them through which dirt clods and some loose tomatoes can fall. The length of the gap is adjustable by moving the upper segment relative to the lower one. The separator includes a walking bar type of shaker with vine retarding tines above the walking bars, and the tines are rotatable and ganged for movement up and down, to adjust dwell time in the separator. The crankshaft for the walking bars has crank pins alternating at 180.degree. and has at each end a pair of timing journals extending at 90.degree. to the crank pins to which the walking bars are secured. The outside journals are located 180.degree. out of phase with the two journals mounted inwardly thereof, to provide two force couples in balance.

Abstract: An improvement is presented in an apparatus for processing soil for planting wherein a separator are provided for initially separating rocks and other large objects from soil prior to crushing thereof, the separator comprising a plurality of respectively upwardly and downwardly directed pins which cooperate in the removal of said rocks and other large objects from the soil. Also provided is a vertical rotatable power driven shaft centrally located in said apparatus wherein a plurality of radially extending arms are fixed thereto and are rotatable with the shaft. Some of said separating pins are fixed to the arms and some cooperating separating pins are fixed to a disc plate also mounted about said power driven shaft. A rotating plurality of discs crush said soil to reduce large particles and destroy weed seeds, insects, and larvae.

Abstract: This invention is concerning a machine for rock removal and soil cultivation of newly broken or established farming areas. The machine picks up soil and rocks to a significant depth, and by a mixing and grinding process, breaks up sod, roots, and lumps of soil and by a classification process returns the size reduced material and small rocks to the ground, and retains the larger rocks.
