Abstract: A device for the control and adjustment of hydraulic cylinders on work attachments and assemblies of work machines, preferably self-propelled harvesting machines. Increasing the performance of harvesting machines for bringing in crops efficiently and without loss requires rapid, uncomplicated adaptation of the harvesting machines and front harvesting attachments to the respective load and operating conditions. The front harvesting attachments and wheel carriages are connected to the hydraulic circuit of the harvesting machine and driven automatically by means of the electronic control system as a function of the respective working and operating conditions.

Abstract: A self-propelling agricultural working machine has a machine frame, a not steerable front axle and a rear axle formed as a dismountable pendulum axle connectable to the machine frame in a predetermined connecting point and provided with steerable wheels, an articulated joint releasably hingedly connectable with the machine frame for coupling the working machine with a trailer vehicle, and connecting elements for alternatingly releasably connecting the pendulum axle and the articulated joint with the machine frame in a region of the connecting point.

Abstract: A drive system for an agricultural large baler with the device for picking up harvested product from field, a device for further transportation of the harvested product a pressing chamber, a pressing chamber, a binding device, as well as a discharging device for discharge of a finally binded bale, the drive system has a power take-off associated with a tractor for displacing the large baler, an input shaft, transmission means provided between the power take-off and the input shaft and including a pre-switching transmission which at an inlet side is drivingly connected with the power take-off and at an outlet side is connected to the input shaft with a hinge shaft, the pre-switching transmission having at least one drive.

Abstract: A harvester thresher has a housing, a straw shaking means, a chopper drum arranged after the straw shaking means and provided with associated counter cutters for comminuting a threshed straw, a width distributing device arranged under the chopper drum for distributing the comminuted straw, the chopper drum being arranged at a height of the discharge end of the straw shaking means, the chopper drum having a drum casing, a shaft supporting the drum casing in the housing, and a plurality of parallel supporting rings arranged at a distance from one another on the drum casing, the chopper drum further having a plurality of impact plates, a plurality of transfer strips associated with the straw shaking means and inserted in ring gaps between the supporting rings, and a plurality of counter cutters which deviate under the action of an overload and extend in the ring gaps between the supporting rings at a different location.

Abstract: A transmission comprises an input shaft and a variator having an infinitely variable transmission ratio. The variator has a variator input being driven by the input shaft and has a variator output. A planetary gear train is configured as a summing gear train with a first input, a second input and an output. The first input is adapted to be drivingly connected to the input shaft and the second input is driven by the variator output. An output shaft is driven by the planetary gear train output. A first clutch is provided for drivingly connecting the first planetary gear train input to the input shaft, whereas a second clutch is provided for drivingly connecting the variator output to the output shaft.
