Abstract: The invention pertains to a device and procedure to regulate the bale length in a square baler. Sensors determine both the forward and backward movement of the crop bundle and transfer these measurements to an evaluation electronic. The evaluation electronic adds the measurements and triggers the tying process when the actual length value is reached. The procedure includes the steps of: sensing both the forward and backward movement of a crop bundle in a baling chamber; adding the measured forward and backward movements to determine an actual length value of the crop bundle; and triggering the tying device once a pre-set target actual length value is reached.

Abstract: A baling press for agricultural harvesting products such as silage, hey, straw and the like, has a depositing device which is bringable into an operating position and transporting position and is operative for depositing pressed bales on a ground surface, the depositing device including a plurality of articulately connected elements, means forming a pressing passage having a housing and an opening, an element arranged to close the opening of the pressing passage in the transporting position, the element being foldable in by approximately 90° to a pressing direction for conversion of the depositing device from the operating position to the transporting position, and further comprising another element which is bringable as a drawer under a bottom of the pressing passage, an actuating device is provided for the depositing device and has a correspondingly operating adjusting members.

Abstract: A device for actuating the clutch of a twine wrap device in a big square baler for harvested crops has a pawl attached to the clutch, a shift lever pivotable into the orbit of the pawl, a control device for the shift lever, and an electric motor which is drive-connected with the control device for the shift lever. The electric motor may be connected via an electric circuit with a device for determining the bale length.

Abstract: Agricultural machine are generally equipped attachments, such as pick-up drums or cutting attachments. Generally, the width of the attachment is greater than that of the main machine or tractor. Because the agricultural machines travel in road traffic, the permitted width of the attachment must not exceed the legally prescribed width of a road vehicle. These attachments usually have supporting wheels for supporting the attachment on the ground. The supporting wheels are mounted and rotate upon carrying arms. Also, the attachment's height above the ground is adjustable by an adjusting device. The attachment provides for positioning the supporting wheels such that the width of the attachment is within the limits permitted in road traffic when traveling in public road traffic, although during working use, the width of the attachment is beyond the width permitted on the road.

Abstract: A system is provided to monitor and control operational functions in a baler such as a big square baler. Clutches and drive components associated with the system are switchable via a speed regulator. Depending on the switch position of the clutches, additional adjusting devices can be engaged or disengaged. The system automatically swings the cutting knives into and out of the feed channel to preclude clogging of the knife slots in the bottom of the feeding channel. It is advantageous to build such a system with several job processing units sharing the same processing software and, at least in part, identical hardware.

Abstract: A drive system for an agricultural large baler having a rearwardly open bale pressing chamber arranged in a longitudinal direction, a pressing piston reciprocatingly movable in the bale pressing chamber, devices for picking up of a harvested product from ground, a transporting passage for collecting a discharge portion of the harvested product and transporting the discharged portion into the bale pressing chamber by an additional transporting device, a binding device for binding a finally pressed bale as well as a drive for driving operational elements, the pressing piston having a crank arm forming a crank circle and provided with a drive shaft element for driving the pressing piston, an input shaft and a transmitting element through which a drive force is transmitted from the input shaft, and intermediate shaft to which the driving force is transmitted through the transmitting element from the input shaft, toothed gears fixedly connected with the intermediate shaft to which the drive force is transmitted, a

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.
