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 roller in the form of a hollow cylinder is for use in harvesting machines and has inner support plates provided within the roller. A plurality of the innermost support plates are connected together by at least one axle section so as to prevent lateral displacement.

Abstract: The invention concerns a 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 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.
