A grain quality sensor comprising a photosite array, an illumination source, a filter, and an electronics module, wherein the illumination source directs light onto a crop sample, wherein the filter limits passage of light into different parts of the photosite array such that certain locations on the photosite array only receive certain wavelengths of light reflected or fluoresced by the crop sample, wherein an electronics module is electrically connected to the photosite array and capable of determining which parts of the photosite array received light and the wavelengths of the light received, wherein the electronics module can analyze the optical data received by the photosite array, and wherein the analysis of the optical data is used to determine the composition of the crop sample.

A control device for controlling a self-propelled combine harvester. The combine harvester comprises a draper having a plurality of conveyor belts driven at a belt speed for collecting and conveying harvested material to a conveying device in the feed channel of the combine harvester, a plurality of working units arranged or positioned downstream from the feed channel for processing the picked-up harvested material, and a drive motor for driving the draper, the conveying device, the working units and a travel drive for operating the combine harvester at a driving speed which is regulated by the control device. The control device is configured to determine the utilization of the drive motor during harvesting mode and to automatically reduce the belt speed of the conveyor belts of the draper when a first limit value for a peak capacity of the drive motor saved in the control device is exceeded.

An agricultural vehicle for picking or harvesting a product includes a motor, a plurality of tires, a transmission mating the motor to the plurality of tires, an accumulator operable to store the product, a module builder operable to receive the product from the accumulator, and a frame supporting the accumulator and the module builder. The frame defines a hatch through which an operator is capable of accessing the motor and/or the transmission. The agricultural vehicle is operable to transition between a first state and a second state. In the first state, the module builder and the accumulator prohibit access through the hatch. In the second state, the module builder and the accumulator are rotated relative to the frame and provide access through the hatch.

A cleaning shoe for an agricultural machine includes a chaffer supported for movement relative to a chassis, a sieve positioned below the chaffer and supported for movement relative to the chassis. The cleaning shoe also includes a first link, a second link, and a drive shaft. The first link includes a first end and a second end coupled to the chaffer. The second link includes a first end and a second end coupled to the sieve. The drive shaft rotates about a shaft axis and includes a first cam and a second cam. The first cam is coupled to the first end of the first link, and the second cam is coupled to the first end of the second link. Rotation of the drive shaft drives the first link to reciprocate the chaffer and drives the second link to reciprocate the sieve. The second cam is angularly offset relative to the first cam by a phase angle less than 180 degrees about the shaft axis.

An agricultural harvester has a chassis, a non-steerable driving front axle and a rear steering axle with a steering mechanism attached to the chassis. A steerable weight transfer axle has a rear steering axle to weight transfer axle linkage assembly linking the steerable weight transfer axle to the steering mechanism of the rear steering axle. The linkage assembly operates to steer the steerable weight transfer axle in coordination with the rear steering axle. The rear steering axle to weight transfer axle linkage assembly has a rear steer axle pivot arm pivotally connected to the rear steering axle and linked to the steering mechanism of the rear steering axle. The rear steering axle to weight transfer axle linkage assembly also has a reversing pivot linked to the rear steer axle pivot arm and to the steerable weight transfer axle.
