Abstract: A combination of a towing vehicle and a baler includes a control unit which is connected to an actuator. The actuator is specified to adjust and/or set an angle between a drawbar and the baler. The control unit, as a function of an unloading signal, is able to be operated so as to actuate the actuator in such a manner that, for unloading a fully formed or fully wrapped bale from the baler in a specified direction, an unloading angle between the drawbar and the baler is able to be set in such a way that the bale is able to be ejected from the baler in the specified direction.

Abstract: A method for operating a baler system including a combination of a tractor and a baler implement includes generating an adaptation signal with an input and output unit and sending the adaptation signal to a tractor control unit. The tractor control unit adapts a driving rotational speed of the drive shaft of the baler implement when the tractor control unit receives the adaptation signal.

Abstract: A combination of a tractor and a baler includes a tractor control unit and a baler control unit. A driving speed of the tractor can be set and/or adjusted with the tractor control unit. The baler includes a bale sensor in order to sense the size of a bale in a baling chamber. The baler control unit is connected to the bale sensor and to the tractor control unit to send a stop signal to the tractor control unit when the bale signal of the bale sensor indicates that a bale has reached a size which is greater than or equal to a first predetermined size. The tractor control unit controls the tractor to initiate a braking operation for stopping the tractor and to adapt a driving rotational speed of the drive shaft of the baler when the tractor control unit receives the stop signal from the baler control unit.

Abstract: A clamping tool for exchanging a mowing blade on a blade rotor, the clamping tool including a lever arm with a fork head, wherein the fork head has two fork legs that are parallel to each other at a distance and have a bent shape such that, with respect to a horizontally oriented lever arm, the fork legs have an arc-shaped construction with fork leg ends pointing essentially in the vertical direction, wherein the clamping tool can be clamped between a mowing disc and a spring plate of a blade rotor and can be brought into engagement with a pocket on a top side of the mowing disc, and the fork leg ends are pressed against the bottom side of the mowing disc by a downward movement of the lever arm, and the fork legs press the spring plate downward.

Abstract: A blade rotor includes a mowing disc, at least one mowing blade, at least one bearing pin mounted on the mowing disc for the pivoting support of the mowing blade, a spring plate arranged on a bottom side of the mowing disc for holding the mowing blade on the bearing pin, and at least one scraper for removing residue stuck on the cutter bar, wherein the scraper is arranged between the spring plate and the bottom side of the mowing disc and is mounted detachably on the mowing disc between the bearing pin and an axis of rotation of the mowing disc.
