A forming shield arrangement configured for a windrowing work vehicle is supported for movement by a support structure. The forming shield arrangement is configured to at least partly shape a windrow of a crop material. A method of operating the forming shield arrangement includes receiving, by a processor of a control system from a memory element, a stored position setting that corresponds to a position of the forming shield arrangement relative to the support structure. The method also includes processing, by the processor, a positioning control signal based, at least in part, on the stored position setting. Moreover, the method includes changing, with an actuator, the position of the forming shield arrangement according to the positioning control signal.

A harvesting work vehicle includes a conditioning arrangement configured to condition a crop material. A method of operating the work vehicle includes receiving, by a processor of a control system from a memory element, a stored conditioning setting for a variable parameter of the conditioning arrangement. The method also includes processing, by the processor, a conditioning control signal based, at least in part, on the stored conditioning setting. Furthermore, the method includes changing, with an actuator, the variable parameter of the conditioning arrangement according to the conditioning control signal.

Agricultural machines such as sprayers can be improved by providing a pressure relief system in the operator cab to allow the operator cab to be pressurized while avoiding over-pressurization. The pressure relief system can be arranged to allow air to freely escape from the operator cab during what would otherwise be an over-pressurization event, such as a door or window being closed. In one aspect, the pressure relief system can include a spring-loaded pressure relief valve configured to passively allow air to escape from the cab in order to maintain a cab pressure at or below a predetermined threshold, such as 100 Pascals. In addition, interior and exterior pressures can be monitored for implementing a closed loop control for the pressurization system to enable a more comfortable experience for the operator.

A windrower has a crop merger attachment with a conveyor configured to receive crop material from a crop conditioning mechanism and direct the crop material to a side of the windrower, the crop merger attachment being mounted for adjusting movement between a lowered and a raised position. The windrower has a swathboard mounted for adjusting movement between a fully raised position in which the crop material passes beneath the swathboard for engagement with the merger attachment and a lowered position in which the crop material down to the ground under the merger attachment under the windrower. A control system automatically adjusts movement of the swathboard when movement of the merger attachment is detected.

A toothed crushing disk for a grain processor includes teeth having a trailing tooth flank, which is a so-called tooth back, and a leading tooth flank, which is a so-called tooth face, on the surface of the teeth. The teeth have a wear protection zone in the region of the tooth back which is continuous or is divided into partial zones and has a wear resistance which is greater than that of the material of a base member of the toothed crushing disk. The base member has a tooth structure which determines the shape of the teeth and the wear protection zone is produced by using a high-energy beam method with the geometry of the tooth structure being substantially maintained. A method for producing a toothed crushing disk for a grain processor having teeth on the surface thereof is also provided.

Crop processing rolls for operative use in forage harvesters are disclosed. The crop processing rolls are formed with a plurality of first grooves that are oriented in a parallel manner with second smaller grooves intersecting the ridges to form discrete teeth from the ridges. The ridges can be formed vertically, horizontally or in a spiraled pattern with the smaller second grooves oriented into a spiraled pattern to form the discrete teeth. Crop processing roll segments can be formed in this manner and assembled into full processing rolls with the spiraled second grooves being oriented in opposing directions from adjacent segments. The number of segments can vary from two to eight individual segments with the second grooves breaking ridges into discrete teeth on adjacent segments forming a chevron pattern at intersecting positions along the longitudinal length of the processing roll.
