A crop baler comprises a frame, a pressing chamber for crop, into which a stuffer can be introduced in order to compress the crop into a bale, a drive for producing a reciprocating movement of the stuffer, and a countermass coupled to the drive and configured to move in a counteracting direction to the movement of the stuffer, the countermass at least approximately compensates movement of the frame induced by the reciprocating mass of the stuffer and the drive unit thereof due to inertia. Alternatively or additionally, a flywheel mass of the drive can have a variable moment of inertia to similarly compensate movement of the frame induced by the reciprocating mass of the stuffer.

A method and an arrangement for control of the speed of a baler includes detection and mapping of one or more of a crop property and data derived therefrom during the harvesting of a field by a combine harvester. Crop residues are deposited in a windrow in the field. The method and arrangement control the speed of the baler in the pickup of the windrow while taking into account one or more of the mapped crop property and the data derived from the crop property.

An agricultural spraying machine having a defined transport width includes a chassis supported on the ground and configured to be set into motion in a forward direction, and a sprayer boom mounted on the chassis. A controller operably controls an actuator influencing the propulsion speed or driving direction of the chassis or the sprayer boom for reducing an oscillation of the sprayer boom in the forward direction. The controller triggers the actuator in response to a detected or expected oscillation of the boom due to a resulting change of speed or travel direction of the chassis or sprayer boom. An oscillation in an opposite phase to the detected or expected oscillation of the sprayer boom is induced in the sprayer boom adapted to lead to the reduction or cancellation of the oscillation of the sprayer boom.
