A track system for traction of a vehicle, such as an all-terrain vehicle (ATV), an agricultural vehicle, etc. The track system comprises a track and a track-engaging assembly for driving and guiding the track around the track-engaging assembly. The track system may be configured to facilitate adjustment of certain aspects of its operation, including, for example, how it is positioned and/or can move relative to a frame of the vehicle, based on one or more factors, such as, for instance, a user's preferences (e.g., riding style, desire to feel the ground, etc.), an environment of the track system (e.g., a profile of the ground, such as a slope or steepness or a levelness of the ground; a compliance of the ground, such as a softness or hardness of the ground, etc.), a state of the track system (e.g., a speed and/or a direction of motion of the track, etc.), a state of the vehicle (e.g., a speed and/or direction of the vehicle, etc.), and/or any other suitable factor. For instance, the track system may comprise a control mechanism configured to adjust an anti-rotation device that is configured to restrict movement of the track system relative to the frame of the vehicle. The control mechanism may be configured to adjust the anti-rotation device in response to a command, which may be input via a user interface or automatically generated by a controller.

A combine harvester is provided that separates grain material from material other than grain using multiple processing areas, including a harvesting area, a feederhouse area, a threshing area, a cleaning area, and a grain delivery area. In a location at or prior to entering one of the processing areas, the material may be collected and held until a collection threshold is reached. Once it is determined that the collection threshold is reached, the material forming a first group of material may be transported from the location to the processing area or a subsequent processing area. The first group of material is transported from the location to the processing area or the subsequent processing area substantially simultaneously and thus simulates the gathering of a large amount of crop material even when small plots are involved. In this way, reduced cycle times may be achieved, and the efficiency benefits of large-plot harvesting may be extended to small-plot applications.

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 assistance system for generating driving routes for one or more driver-controlled or autonomous agricultural work machines. The assistance system includes a computer configured to create a driving route for an agricultural work machine configured to work an agricultural area on the basis of a saved strategy, which may take into account features of areas adjacent to the agricultural area which are not to be worked.

A screening device and a self-propelled harvester with a screening device. The screening device includes at least one suction nozzle that has an elongated hollow body with at least one suction opening which extends sectionally in the longitudinal direction and transverse direction of the hollow body, and is connected by at least one air duct in the interior of the hollow body to a connection arranged in the hollow body for connecting to a vacuum source. The suction opening is positioned facing a screen of the screening device. The air duct has a cross-sectional shape that increases in the vertical direction toward the connection starting from an outer end of the suction nozzle. An inner contour facing the suction opening of the air duct has a contour that substantially corresponds to an airfoil.

Geotagged information about a crop harvest is captured while harvesting. The geotagged information may be communicated to a management system or other work machines. The geotagged information may be utilized by a tractor or other work vehicle during collection of the harvested crop. For instance, the vehicle may automatically control a speed or output information on a display to aid an operator to control the speed.
