The harvester header height control system allows automatic adjustment of the header height as the harvester moves across a field to optimize the harvest of the produce in the field. The header height control system adjusts for the topography of the field, the density and health of the plants in the field and the speed of the harvester.

An assistance system for optimizing a forage harvesting process is disclosed. The assistance system supports a user in optimizing an agricultural job that describes a forage harvesting process. Optimizing the forage harvesting process comprises at least the planning and/or execution of the forage harvesting process chain effecting the implementation of the agricultural job. The forage harvesting process chain comprises process steps and agricultural work machines which process the agricultural job in a specified sequence. The assistance system optimizes execution of the agricultural job according to specified strategies by selecting optimal values for work parameters and an optimized sequence of process steps.

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.

The Multipurpose Leaf Crop Harvesting Apparatus and Processing Method will accomplish seven steps in one pass of the combine harvester. This apparatus and processing method harvests leaf crops and is configured to perform multiple processing operations, including fractionation of the leaf crop, leaf maceration, leaf sizing, elevating the leaf fraction to a transport vehicle, and stem conditioning, cutting and windrowing, in a single pass through the crop field. These steps are accomplished using a header unit, an adapter feeder macerator and a forage harvester vehicle, expeditiously removing the leaf fraction from the field. Following leaf fraction harvesting, the leaf fraction is processed by densification into forage feed products. The processed leaf fraction can be combined with other feeds to make up customized feed rations. The stem fraction is also processed. The present invention can also be used to harvest grass crops.

A combine head and stalk roll retention shaft apparatus. The combine head may include a plurality of combine head row units. A drive system is provided to drive the row units and a stalk roll feeder; the feeder having a drive system to drive the feeder and feed corn stalks into at least one of the plurality of combine head row units. The stalk roll retention apparatus may be slidably attached proximate to the tip of the stalk roller shaft to reduce wear of the stalk rollers and guide the corn stalks into the row unit(s). The stalk roll retention shaft apparatus may include one more bearings. The stalk roll retention shaft apparatus may also include a cap or plug on the front of the apparatus.

The invention relates to a processing machine for processing fibre plants, such as hemp or flax. The processing machine can comprise:a self-propelling vehicle;a seed part removing unit which is mounted on the self-propelling vehicle and is configured to remove seed parts (such as bolls) from the fibre plants to be picked;a picking unit which is mounted on the vehicle and is configured to pick fibre plants from which seed parts have been removed, wherein the picking unit is further configured to transport the picked fibre plants to the conveyor of the self-propelling vehicle. The seed part removing unit can for instance be a stripper for stripping the seed parts from the fibre plants.

A harvesting system has a harvester that harvests a crop in a crop field. A position component senses a position of the harvester and provides an indication of the sensed position. A crop parameter sensor senses a crop parameter and provides an indication of the sensed crop parameter. A crop gap determination component determines determine a crop gap location, based on the indication of the sensed position and the indication of the sensed crop parameter.
