Abstract: An agricultural baler comprises a baling chamber and pick-up device for collecting crop material from a field and feeding it to conveyor mechanism which transports it into the baling chamber. A plunger reciprocates therein for compressing the crop material to a package and a tying mechanism encircles the package with one or more strands of tying material, thereby forming a completed bale. The baler comprises bale discharge device disposed at the outlet of the baling chamber, the bale discharge device being movable between an extended position for receiving the completed bale and depositing it onto the field and a retracted position for reducing the overall length of the baler. In the retracted position, a rear portion of the bale discharge device is rested on a support on top of the baling chamber. The discharge device are held in their retracted position by the rear portion itself.

Abstract: A baler for agricultural products has a chassis, a pickup, a transporting passage, a pressing chamber, a binding device, a discharging device, a working element performing working operations in the baler, a main drive shaft connected with the working element for driving the working means, at least one planetary summing transmission connected with an operative for driving the main drive shaft, a first drive unit including a cardan shaft and transmitting rotation with a first rotary speed to the planetary summing transmission, and a second drive unit transmitting a rotation to the planetary summing transmission with a second regulatable rotary speed, so that the planetary summing transmission summarizes the rotary speeds of the first and second drive units and produces a rotation with an output speed for driving the main drive shaft.

Abstract: Method and apparatus for fine-adjustment of moving part sequences in big square balers and, in particular, for adjusting the insertion point of the needle bar and the timing of the feeding mechanism for the baling material. The fine-adjustment is accomplished by pivoting an angle adjustment mechanism, which is jointly pivotable with an intermediate drive shaft, at a maximum pivot angle of 10 degrees, but preferably 2 to 3 degrees in either forward or backward pivot directions.

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.
