A system (42) and computer-implemented method for sensing an amount of ash in cut crop material and automatically adjusting an operating parameter of a mower conditioner to optimize the amount of ash. A sensor (50) measures an measured ash content value of the crop material after it is cut, a processor (48) compares the actual value to a threshold value, and if the actual value exceeds the threshold value, automatically adjusts an operating parameter, such as a height, angle, or speed at which the crop material is cut, a float pressure of the header (12), or a ground speed of the machine (10). Other sensors (64) may measure a roughness of the cut, an excessive stubble height, or other data relevant to optimizing quality, which may also result in adjustments to the operating parameters. The processor (48) may consider an operator-selectable value weighting the measured ash content versus a speed of operation when adjusting the operating parameter.

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 system for determining the cut quality of a crop by a harvester includes an electrode maintained at voltage above ground. The electrode is mounted downstream of a cutter bar on the harvester. The electrode communicates with a controller which measures changes in an electrical parameter, such as voltage or current, between the electrode and ground. The electrode is positioned to ride at a particular height above the ground specific to a particular crop. Crop stubble left by crop which is cut cleanly by the harvester does not contact the electrode. Crop stubble left by crop which is not cut properly will engage the electrode and effect a change in the electrical parameter measured by the controller. The controller reports changes in the electrical parameter indicative of cut quality to the operator of the harvester via a display device thereby allowing the operator to take corrective action in harvester operation.

A conveying and conditioning roller for a harvesting machine is provided on the surface thereof with teeth in the form of toothed strips which extend over the longitudinal extent of the roller and in each case have a leading tooth flank and a trailing tooth flank as well as a tooth edge. The roller is provided with wear protection zones continuously or in partial regions, the wear resistance thereof being greater than that of the material of the base body of the roller. The base body has a tooth structure determining the shape of the teeth and tooth wear protection zones are formed on the trailing tooth flanks by a high energy radiation process, substantially maintaining the geometry of the tooth structure, roller wear protection zones being formed together thereby on the rollers, as well as a method for producing such a roller wear protection zone.

A system and computer-implemented method for sensing an amount of free water in cut crop material and automatically adjusting an operating parameter of a mower conditioner to optimize the amount of free water. A sensor located at the exit of a conditioning mechanism measures an actual free water content value of the material as it exits the conditioning mechanism, a processor compares the actual value to maximum and minimum values, and if the actual value is outside this range, automatically adjusts an operating parameter, such as a gap between pairs of conditioning rollers, a pressure exerted by the rollers, or a speed of the mower conditioner, to optimize the actual value. Another sensor may be located at the entrance of the conditioning mechanism. The processor may take into account an operator-selectable value weighting the actual free water content versus a dry down time when adjusting the operating parameter.

A header includes: a header frame; a cutter carried by the header frame; a roll disposed rearwardly of the cutter and configured to convey cut crop material rearwardly in a crop flow stream; a swath gate coupled to the header frame and movable between a spreading position and a converging position; a spreader coupled to the swath gate and configured to laterally spread the crop flow stream as the crop flow stream flows across the spreader; and a converger coupled to the swath gate and configured to converge the crop flow stream toward a centerline of the swath gate as the crop flow stream flows across the converger. The spreader and the converger are configured to not be in the crop flow stream at the same time, depending on the position of the swath gate.

An impact mill (10) has an inlet (12) for material to enter the mill, an impact mechanism (16, 50) arranged to rotate about a rotation axis and being operable to pulverise the material after entering through the inlet, and an outlet (154) for discharge of pulverised material. Blockage sensors (Bj), vibration sensors V, torque sensors Tn, temperature sensors and proximity sensors may be selectively incorporated into the mill.
