Abstract: An agricultural working machine has a first axle and a second axle, multiple ground-engaging means disposed at the first and second axles that are at least partially drivable by a drive engine or are steerable using steering-knuckle steering, a steering-angle sensor disposed at a steerable ground-engaging means for detecting a set steering angle (?th) and a steering brake for the selective braking of one or more drivable, ground-engaging means for steering support. A control unit controls and regulates the at least one steering brake based on a steering angle (?th, ?tat) or a slip angle (?) of at least one of the steerable ground-engaging means.

Abstract: A steerable crawler track for an agricultural utility vehicle such as a tractor or a self-propelled harvesting machine has a left-side track roller unit, a right-side track roller unit, a differential having a transmission input driven by an engine, a first transmission output for driving the left track roller unit, and a second transmission output for driving the right track roller unit and a hydraulic transmission having a variable transmission ratio (i). The transmission outputs of the differential are coupled to one another via the hydraulic transmission such that the ratio of the rotational speeds (nl, nr) of the transmission outputs are influenced by changing the transmission ratio (i) of the hydraulic transmission.

Abstract: A turning drum of self-propelling harvester thresher is arranged after a threshing mechanism and has a closed casing with a plurality of rows of ribs extending parallel to a rotary axis of the drum. The ribs are inclined by substantially 20.degree.-40.degree. relative to a traveling direction of the harvester thresher. Thereby, the grains which strike against the inclined ribs are deviated, and as a result their striking energy is reduced and the grain breakage is prevented.

Abstract: A self-propelling harvesting thresher comprises threshing means, and a post threshing and separating mechanism, the post threshing and separating mechanism operating in accordance with an axial flow system and including two rotors located near one another and driven in the same direction and a housing surrounding the rotors and provided with guiding means above each drum for guiding a product, the housing being expanded above the rotors.

Abstract: A drawing roller of a cutting trough of an agricultural machine, particularly a harvester thresher, has a drawing roller body rotatably mounted in a cutting trough, oppositely operating screw plates arranged at outer ends of the roller body, a plurality of controlled drawing fingers arranged on the roller body in a central region thereof, and at least one rigid driving member arranged on the roller body in the central region in addition to the controlled driving fingers.

Abstract: A motorless harvester thresher is coupled with a multi-purpose vehicle by means of a coupling rod and a coupling linkage extended between the vehicle and the thresher and pivotally mounted to a lateral side of the vehicle and to a laterial side of the thresher.A driven front axle of the vehicle supporting the front wheels thereof coupled with a non-steerable front axle of the front wheels of the harvester thresher by means of the coupling rod connected to a clutch which can be engaged to or disengaged from the coupling rod so as to ensure the axial alignment of front axes of the vehicle and the machine so as to provide for a stable lateral position of the thresher relative to the vehicle in the traveling movement thereof.

Abstract: A harvester-thresher combine includes two threshing and separating drums which are mounted in a common housing for rotation in the same sense about parallel axes. The axes may extend in planes which extend parallel to the direction of movement of the combine, and then the leading ends of the drums are conical and have an external helical projection thereon. A twist-inducing conveyor may extend at an angle to the direction of movement of the combine into a corresponding cutout in the common housing. The drums may have equal or unequal lengths and in the latter case they are so arranged that the trailing end portions form a discharging step registering with a discharge opening of the housing.

Abstract: A harvester thresher has threshing elements and a plurality of separating elements each including a separating drum and a separating element located below the drum and provided with perforations and rubbing projections, a plurality of pairs of lateral wall members laterally limiting and holding a respective one of the separating elements, and a bar-shaped elongated supporting element extending in the direction of transportation, so that the separating elements are arranged on and shiftable over the supporting element as units.

Abstract: A radial blowing device for a harvester thresher cleaning arrangement has at least two blowers each having a double impeller with two sets of blades, two wind passages each extending from a respective one of the impellers, and two partitions each subdividing a respective one of the wind passages into two half passages, so that each of the half passages communicates with a respective one of the sets of blades of a respective one of the impellers, and each of the partitions extends up to the rotor of a respective one of the impellers.

Abstract: An agricultural baler has a device for picking up stalk-type and blade-type vegetation. The picked up vegetation is inserted into a precompacting chamber wherein it is subjected to initial compacting. The degree of compaction is sensed and, when it reaches a preselected magnitude, the precompacted body of vegetation is expelled from the precompacting chamber into a main compacting chamber. The precompacted bodies are of identical or substantially identical size and density.
