A crop unloader system comprising: an elevator assembly, a boom assembly, a flexible drive, and a tensioning assembly. The elevator assembly has a frame, an elevator drive and drive motor, and an elevator drive output. The boom assembly has a frame connected to the elevator frame at a boom pivot axis to rotate through a range of motion, and an unloader drive input. The flexible drive is operatively connected between the elevator drive output and the unloader drive input. The tensioning assembly has a tensioner link and a control link that are pivotally to each other and with one of the two links each pivotally connected to one of the boom and elevator frame. An idler wheel is on the tensioner link. The tensioning assembly maintains a tension load on the endless flexible drive within a predetermined range, throughout the range of motion of the boom frame.

One describes a feed-belt (100) for a sugar-cane harvester, comprising first (1) and second (2) belts that substantially overlap each other and define a space for passage of cut cane between them (1, 2), the first and the second belts (1,2) exhibiting a substantially curved profile. The invention has the objective of providing a feed-belt (100) for a sugar-cane harvester that can be used for the processes of both harvesting cane for grinding and harvesting seedlings for plantation, also providing a decrease in the total weight of the machine, lower hydraulic power required for the feed assembly, a smaller number of hydraulic components and lower final cost of the machine, besides simplicity and lower maintenance cost.

An agricultural harvester includes a chassis; a cleaning system carried by the chassis and is configured to clean crop material; and a crop material elevator carried by the chassis that is supplied with cleaned crop material from the cleaning system. The crop material elevator includes: a housing including a boot portion at a bottom of the housing, the boot portion defining a bulbous shape on at least a conveyance side of the housing; a driving loop held within the housing and configured to rotate; a driving element linked to the driving loop and configured to rotate the driving loop; and a plurality of paddles carried by the driving loop.
