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 calibration system for an agricultural vehicle includes: a motor-driven component; a motor coupled to the motor-driven component and configured to move the motor-driven component between a maximum distance position and a home position; and a controller operatively coupled to the motor. The controller is configured to: enter a component calibration mode; output a first movement signal to the motor to cause the motor to carry the motor-driven component toward the maximum distance position; determine that the motor-driven component has reached the maximum distance position; output a second movement signal to the motor to cause the motor to carry the motor-driven component toward the home position; and determine that the motor-driven component has reached the home position.

A round baler includes a first roller and a second roller that define a gap therebetween and are arranged to position forming belts immediately adjacent to a baling chamber. A third roller is arranged to position the forming belts radially outward of the baling chamber. The forming belts move along a belt path in sequence from the first roller, to the third roller, and then to the second roller, such that the baling chamber is not bounded by the forming belts in the gap between the first roller and the second roller. A net guide is radially supported by both the first roller and the second roller and laterally positioned between an adjacent pair of the forming belts. The net guide extends across the gap to guide a net material across the gap and prevent the net material from following the forming belts away from the baling chamber.

An agricultural baler system includes: an agricultural baler including a bale chamber configured to form a bale from crop material, a crop conveyor configured to feed crop material into the bale chamber, a location sensor configured to output a location signal corresponding to a location of the agricultural baler, and a parameter sensor configured to output a parameter signal corresponding to a measured parameter; and a controller operably coupled to the travel sensor and the parameter sensor. The controller is configured to: determine an area based at least partially on a rake width of a rake and a defined length; determine a parameter distribution in a region of a field having the area based at least partially on the measured parameter and the location of the agricultural baler; and output a field map update signal to update a field map to indicate the determined parameter distribution.

A cotton harvester estimates the mass of cotton as it is harvested using sensor devices and compares the mass of each module against the estimated mass of the module as determined by the sensors so that a calibration factor may be determined and actively updated for more accurate crop yield determination. The mass flow for a specific module is accumulated and processed during harvesting using a base calibration factor and the module is weighed and compared against the expected mass using the base calibration factor to develop a candidate updated calibration factor. The base calibration factor is selectively replaced by the candidate updated calibration factor for processing a subsequent module based on machine feedback information relating to the operation of the harvester. Harvested crop data determined using the calibration factor is used to generate highly accurate yield maps.

A hydraulic system for a rear gate of a baler implement includes a fluid circuit having a first portion connected to and disposed in fluid communication with a first fluid port of a hydraulic cylinder. A flow bypass assembly is disposed in the first portion of the fluid circuit. The flow bypass assembly includes a flow rate control valve selectively moveable between a first position allowing fluid communication therethrough at a first flow rate, and a second position blocking fluid communication therethrough. The flow bypass assembly further includes a bypass passageway for circulating the fluid when the flow rate control valve is closed. A flow restriction is disposed within the bypass passageway to provide a second flow rate that is less than the first flow rate.

Method and device for tagging round bales during wrapping in plastic foil, using a stationary or mobile baler-wrapper. Each round bale is oriented with the circular end surfaces mainly vertically and layers of plastic foil is wrapped around the round bale by foil wrapping arms. At a point in time where at least one layer of plastic film remains to be wrapped, each round bale is tagged with an ID tag having an adhesive back-side surface, using a time controlled, pivotal tagging arm provided with a tag transferring member. The movement of said tagging arm is controlled by a computer, which synchronizes the movement of the tagging arm with the movement of the foil supplying arms. After tagging, at least one additional layer of plastic is wrapped around each round bale to protect the ID tag.
