One or more information maps are obtained by an agricultural system. The one or more information maps map one or more characteristic values at different geographic locations in a worksite. An in-situ sensor detects a mass flow value as a mobile machine operates at the worksite. A predictive map generator generates a predictive map that maps predictive mass flow values or predictive yield values at different geographic locations in the worksite based on a relationship between the values in the one or more information maps and the mass flow value detected by the in-situ sensor or the yield value based on the detected mass flow value. The predictive map can be output and used in automated machine control.

A harvesting header of an agricultural machine includes a frame, a cutting mechanism coupled to the frame and configured to cut crop, an auger rotatably coupled to the frame at a location rearward of the cutting mechanism, and an impeller rotatably coupled to the frame at a location rearward of the auger. The impeller is configured to receive crop from the auger and condition the cut crop. The crop is projected by the auger in a rearward and upward direction relative to the impeller.

A method includes cutting hay in an agricultural field, determining a mass of the hay, determining a moisture content of the hay, determining an ash content of the hay, calculating a corrected yield of the hay, and labeling the hay with an indicator of the corrected yield of the hay. The corrected yield is based on the mass, the moisture content, and the ash content of the hay.

In one embodiment, a skid plate comprising an upper surface and an opposing ground engaging surface, the ground engaging surface comprising one or more optical windows flush or extending beyond a plane of the ground engaging surface, each of the optical windows comprising an optically transparent material.

A harvesting header has a set of centrally disposed conditioner rolls comprising conditioning structure to condition crop and a rotary cutter bed. The rotary cutter bed has a plurality of rotary cutters extending across the path of travel of the header to define a cutting plane, each cutter being rotatable about an upright axis, the conditioner rolls being behind the cutter bed to condition crop cut by the rotary cutter bed. The header has a crop-directing header windguard configured to direct the crop down towards the conditioning rolls after the plurality of cutters have severed the crop, the header windguard extending in a rearwardly direction from a position forward of the cutter bed to a position proximate the conditioner rolls, and the header windguard extending transversely at least a width of the rotary cutter bed.

An agricultural harvester is disclosed. The agricultural harvester comprises a header. The header includes a frame, a control shaft connected to the frame, a flex arm, a linkage assembly and a cutter bar connected to the flex arm. The linkage assembly is movable between a first position and a second position. The linkage assembly includes a first end pivotably connected to the control shaft and a second end connected to the flex arm.

One or more techniques and/or systems are disclosed for automatically adjusting conditioning rollers of a windrower implement, such as those used to condition hay and other windrowed crops. Adjustments can be made on the fly to rollers used to condition the crop based on several factors such as the condition of the crop, the density, speed, header conditions, and more. Sensors can be used to detect the crop's and others' conditions, and automatic adjustments can be made, such as the distance between conditioning rollers, and/or the pressure applied by the rollers, to meet a desired crop condition for the windrows.

A disc cutter for an agricultural implement includes: a disc body; a knife nut coupled to the disc body; a knife including a knife opening in which the knife nut is disposed, the knife being configured to rotate about a rotation axis defined by the knife nut; and a spring plate carrying at least two protrusions, the spring plate being biased towards the disc body such that in a first position the spring plate bears on the knife so a plane defined through a portion of the knife extends through the protrusions until an overload force applied to the knife forces the knife over at least one of the protrusions and moves the spring plate to a second position.

A mower is configured to cut plant material as the mower moves over a field and deposits the cut plant material on the field. The mower includes a header assembly having a cutter bed, conditioning rollers, and a swathboard, the swathboard being positionable to shape a rearwardly-directed stream of cut plant material into windrows. The header assembly includes a sensor system mounted on the swathboard. The sensor system has a sensor configured to collect nutrient information of the plant material being cut by the mower, where the sensor is moveable relative to the swathboard so as to move the orientation of a sensor face with respect to the crop stream.
