In one embodiment, the present disclosure includes a dispenser vane comprising a flexible outer surface and a plurality of flexible teeth arranged along the length of the outer surface. The flexible outer surface and flexible teeth are radially moveable.

In one embodiment, the present disclosure includes a dispenser vane comprising a flexible outer surface and a plurality of flexible teeth arranged along the length of the outer surface. The flexible outer surface and flexible teeth are radially moveable.

In one embodiment, the present disclosure includes a solid dispenser including dispensing vanes coupled rotationally about respective parallel horizontal axes. The two dispensing vanes including a surface at a radial distance from the corresponding parallel horizontal axis with teeth arranged on and projecting from the surface. The surfaces of the dispensing vanes may be in contact between the parallel horizontal axes and are flexible in radial directions of the dispensing vanes. In one example embodiment, the dispensing vanes are configured to rotate in opposing directions about the respective parallel horizontal axes to selectively dispense ingredients from a hopper.

A component supply device configured to output a predetermined number of components to be used in a work operation includes a fixing plate having a via-hole through which the components pass, the fixing plate being fixed to a housing, a movable plate having a storage hole penetrating through the movable plate in an up-down direction and having a size that allows the predetermined number of components to be stored, the movable plate being laminated on a top side of the fixing plate and configured to move such that the storage hole moves relative to the via-hole in a direction parallel to a top face of the fixing plate, a controller configured to control an operation of the movable plate, and an elastic member placed on a top side of the movable plate and configured to elastically deform in a direction parallel to a top face of the movable plate.

A control assembly provides autonomous control of various functions of a grain cart and/or provides guidance to an operator of the grain cart during the unloading of a grain cart. The control assembly collects input from one or more sensors including a speed sensor to monitor speed of a PTO that drives the unloading auger of the grain cart, a height sensor that measures the height of material discharged from the grain cart into a receptacle such as a grain truck, and/or a boundary sensors that measure lateral position of the grain cart relative to the receptacle or grain truck. Based on the input, the control assembly may vary the position of the discharge gate of the grain cart, or provide guidance to the operator to steer and position the grain cart relative to an adjacent grain truck.
