Abstract: The present invention relates to a round baler for agricultural crop material having a press chamber for pressing the crop material and a wrapping device for wrapping the fully pressed round bales of crop material, wherein the wrapping material is secured on a web roll. The web roll is provided with a brake rod acting on the outside diameter of the bale. The essential characteristics of the invention are that a brake rod is affixed to one lever arm of a two-armed pivot lever and the effective linkage point of a plurality of tension springs is positioned the other lever arm. The linkage point's position is automatically variable relation to a stationary pivot point of the pivot lever as a function of the respective diameter of the web roll.

Abstract: A round baler has a bale chamber, a plurality of bale forming elements which limit a periphery of the bale chamber so that a volume of the bale chamber can be increased during a formation of a bale by the bale forming elements, a common lever structure on which the bale forming elements are arranged, the lever structure formed as a turnable lever structure supports the bale forming elements so that at least one of the bale forming elements, when the lever structure is turned outwardly, still extends inwardly into a peripheral circle formed by the other of the bale forming elements.

Abstract: A piston operated collecting machine for an agricultural harvested product comprises a pressing piston, a collector for collecting a harvested product, a feeding element for supplying the harvested product to the collector, a transmission having an input shaft connectable with a drive shaft of a pulling vehicle and imparting a movement to the pressing piston, two driven shafts operating so that one of the driven shaft drives the collector while another of the driven shafts drives the feeding element, and two overloading couplings arranged so that one of the driven shafts is connected with the transmission through one of the overloading couplings, while another of the driven shafts is connected with the transmission through another of the overloading couplings.

Abstract: The present invention relates to a spherical baling press with press and conveyer cylinders bordering the pressing area on the periphery with room left for a product entry slot. When viewed in the rotational direction of the bales, press cylinders located in front of the entry slot are gradually positioned closer to the periphery resulting in a spiral shape of the pressing area in front of the entry slot. As a result, the bale is in part compressed to a higher degree which has a particularly beneficial consequence if the product being baled consists of brittle straw.
