A roll assembly, which may be included in an agricultural baler, includes: a first roll having a first roll surface with a plurality of first extensions extending therefrom, the first extensions defining a first rotation path when rotated; and a second roll having a second roll surface with a plurality of second extensions extending therefrom, the second extensions defining a second rotation path when rotated. The first roll and the second roll are disposed adjacent to one another such that the first rotation path and the second rotation path partially overlap. At least one roll driver is coupled to at least one of the first roll or the second roll and configured to rotate the first roll and the second roll in the rotation direction such that the first extensions and the second extensions do not collide with each other during rotation of the first roll and the second roll.

A round baler has a rear door pivotable relative to the frame. A circulating press element defines a press chamber inside the frame for forming crop bales. A tension rocker is pivotable relative to the frame and has a rotatable rocker guide roller guiding the press element. A first pressure element is arranged at frame and rear door and acts between frame and rear door. A second pressure element is arranged at rear door and tension rocker and acts between rear door and tension rocker. At least one of the pressure elements is a linear actor. By length expansion of the first pressure element, rear door and tension rocker are pivotable, wherein the rear door is pivotable upwardly to enable ejection of crop bales. The rear door is pivotable downwardly by length expansion of the second pressure element. A method for operating the round baler is provided.

A worm conveyor is proposed for a press, in particular an agricultural baler, having at least one roll, screw flights winding in opposing directions at least in some regions around the roll being provided on the peripheral surface thereof for conveying material, wherein the screw flights are configured such that they bring together the material in two collecting regions arranged outside a central region of the worm conveyor. A press, in particular an agricultural baler having at least one roller, a flexible pressing means winding around the roller and at least one worm conveyor are also proposed.

In a method for providing a bale of crop material that is only partially wrapped in a film, a bale of crop material is wrapped in a film with an automatic bale wrapping apparatus. Subsequently the film is provided with a plurality of perforations, and it is ensured that the perforations are present/positioned in an upper half of the bale. This ensures that there is good moisture control of the bale, with moist air able to escape, while stopping ingress of rain water. The bales are mostly dry hay or the like, and favourable perforations are radial slits. There is also provided a system for providing such bales with position controlled perforations.

An agricultural baler includes: a chassis; a plurality of wheels carried by the chassis; at least one electric wheel motor coupled to at least one of the plurality of wheels and configured to drive the at least one coupled wheel; an apron assembly including a plurality of chains driven by a plurality of rolls and configured to form a bale, the plurality of rolls including a starter roll; an electric drive motor coupled to the starter roll and configured to drive the starter roll; and an electrical power system carried by the chassis and having at least one battery electrically coupled to the at least one electric wheel motor and the electric drive motor.

Yield monitoring systems for round baling machines and methods that can provide weight estimations for round bales at the time of formation are described. Balers can include those that incorporate hydraulically actuated bale kicking or pushing assemblies as well as those that incorporate spring-loaded off ramps. Farm implements including baling machines and cotton module builders are encompassed. The system includes a sensor that can ascertain a physical parameter associated with ejection of a round bale from the farm implement. Physical parameters as may be ascertained can include pressures, velocities, accelerations, etc. associated with bale ejection.

The present invention relates generally to wood chippers and baling machines and methods of operation therefor, and more specifically, to an apparatus and a method for chipping tree branches and the like and baling wood chips formed from such chipping activities. The apparatus includes a chipper assembly having a chipping mechanism operable to reduce the trimmed branches to wood chips. Also provided is a bale forming assembly operatively connected to the chipper assembly. The bale forming assembly has a housing and a baling mechanism contained within an interior space of the housing. The housing has an opening defined therein for receiving wood chips from the chipper assembly. The opening provides access to the interior space of the housing. The baling mechanism is operable to form a bale from the wood chips produced by the chipper assembly.

A stripper device, for reducing adhesions on a movable part of a baler including a pressing apparatus interacting with a bale, has a scraper bar carrier with a scraping bar, wherein the scraping bar carrier can be movably connected to the baler and has a first position, in which the scraping bar is operatively abutted against the pressing apparatus, and a second position, in which the scraping bar is withdrawn from the pressing apparatus, wherein the scraping bar assumes the second position cyclically.

A baling device to form bales of crop material, including a frame, an intake device, a bale forming device for forming a bale of the crop material, the bale forming device including at least one endless belt to delimit a baling chamber, and a number of guiding elements to guide the endless belt, the outlet of the intake device is located at a fixed position with respect to the frame, and at least three guiding elements are movably mounted with respect to the outlet of the intake device to position for subsequent bales different pairs of two guiding elements of the at least three movable guiding elements at the opposite sides of the outlet.

A baler ejection system, that may be used with an agricultural harvester, such as a round baler, waste baler, combine, or cotton harvester, uses the motion of a pair of parallel arms that extend transversely from the sidewalls of a bale chamber a set of distinct pivot points. When activated the parallel arms raise to expose an outlet through which the bale may be ejected. A formed bale may become ejected by one or more conveyer belts that exert a rearward force on the bale within the bale chamber.
