A feed roll includes paddles mounted upright on a cylindrical surface of the roll and oriented parallel to its rotation axis, and V-shaped vanes in a central area of the feed roll. One or more paddles or paddle portions are located in the central area. The paddles or paddle portions may be located between the blades that define the V-shaped vanes, i.e. blades which extend between a top point at or near the tip of the V-shape and a base point at the base of the V-shape. Paddles may be present between the base points of one or more of the V-shaped vanes, and additional intermediate paddles may be located between the top points and the base points of the blades. The paddles or paddle portions in the central area enhance the capability of deflecting objects away from the threshing rotors downstream of the feed roll in a combine harvester.

A combine harvester is provided with: a threshing device that performs a threshing process of threshing a crop; a grain tank that stores grain obtained by the threshing process; a grain discharging device that discharges grain to be stored in the grain tank to the outside of the vehicle body; a travel driving device that drives travel of the vehicle body; and an engine that serves as a power source. The combine harvester includes a first relay shaft to which power is transmitted from an output shaft of the engine, and the power of the engine is transmitted from the first relay shaft to the grain discharging device and the travel driving device in a branched manner.

An agricultural vehicle including a chassis and a threshing system supported by the chassis. The threshing system includes a rotor, a front concave located at a distance radially away from the rotor and at least partially surrounding the rotor, and an infeed ramp connected to the front concave. The infeed ramp is located at a distance radially away from the rotor and has a plurality of slots therein. The threshing system also includes a support member positioned underneath the infeed ramp and a plurality of vanes connected to the support member. Each vane extends through a respective slot of the plurality of slots and is located at a distance radially away from the rotor. The vanes are configured for contacting and directing the crop material rearwardly towards the front concave.

A combine harvester includes a load-bearing undercarriage movable via a drivable device engaged in the ground, a threshing and separating device attached to the load-bearing undercarriage, and a feeder house attached to the load-bearing undercarriage. The feeder house includes an endless traction mechanism which circulates about a vertically movable lower deflection roller and a drivable upper deflection roller. A harvesting attachment is coupled to the feeder house for receiving or cutting off harvested crops which are lying or standing upright on a field and which are able to be supplied via the feeder house to the threshing and separating device. An actuator is actuated by an external force arranged for adjusting the vertical position of the lower deflection roller and is connected to a control device which is coupled to a sensor for determining a throughput by a transmission of a signal.
