Abstract: A leaf removal assembly including a frame comprising a front plate having a feed opening, a leaf stripping assembly mounted on said front plate in front of said feed opening and an upper sprocket wheel comprising a plurality of upper socket grippers extending radially outward of the upper sprocket wheel and being disposed behind the front plate. The leaf removal assembly further includes a lower sprocket wheel comprising a plurality of lower sprocket grippers extending radially outwardly of the lower sprocket wheel and being disposed behind the front plate. At least one of the upper sprocket wheel and the lower sprocket wheel may be adjustably attached to the frame. A process for separating a leaf from a stalk comprising at least one leaf is also included.

Abstract: A conveying and separating device for root crop has a separating stretch with at least two rotatingly driven separating rollers, wherein the separating stretch receives a harvested material of root crop and admixed parts and wherein the at least two separating rollers transport on a topside of the separating stretch primarily the root crop while the admixed parts are removed in a screening phase through a screening gap between the at least two separating rollers. By a direct forced cleaning action, the at least two separating rollers are kept free at least of admixed parts that can adhere to the at least two separating rollers.

Abstract: A combine having a variable speed drive that rotates at least one of a plurality of thrashing cylinders that thrash crops. Three of the thrashing cylinders have a gradually increasing number of flexible fingers that thrash the crops. The combine also includes a drum separator located downstream of the thrashing cylinders with respect to the direction of crop flow in the combine. The drum separator separates desirable portions of the crops and is part of a tailings return system. The combine also includes disk separators that are configured to minimize damage to desirable portions of the crops.

Abstract: A towed type beet harvester includes a main frame having ground engaging wheels and having a lifter wheel assembly for excavating beets, potatoes, carrots and similar root crops. A front set of grab rollers are positioned rearwardly of the lifter wheel assembly and are coated with a high impact plastic material to minimize damage to the harvested crop. A rear set of grab rollers are positioned rearwardly of the front set of rollers and are also coated with a high impact plastic material. A vertically disposed discharge wheel assembly is positioned interiorly of the harvester main frame and conveys harvested crop to a reversible discharge conveyor. An open top holding tank is mounted at the rear of the harvester for temporarily holding the harvested crop during the harvesting operation.

Abstract: A sugar beet harvestor having a grab roller assembly is equipped with a cleaner for removing mud and debris from the rollers of the grab roller assembly. The cleaner has a pair of rails that movably support a traveler. Downwardly directed blades attached to the traveler have lower ends located in close proximity to the rollers of the grab roller assembly. A reversible power driven drive operates to reciprocate the traveler along the rails thereby moving the blades relative to the outer surfaces of the rollers so that mud and debris on the rollers are removed therefrom.
