Abstract: A header for an agricultural vehicle. The header includes a header frame and an elongate sickle knife mounted along a leading edge of the header. The header further includes an actuator for reciprocally moving the elongate sickle knife in its longitudinal direction relative to the header frame between a first position and a second position over an intermediate position. At least one accumulator extends between the header frame and the elongate sickle knife to accumulate energy during a first movement of the elongate sickle knife from the intermediate position towards at least one of the first position and the second position, and to release accumulated energy during a second movement of the elongate sickle knife opposite to the first movement.

Abstract: A header for a combine harvester has a primary implement, a secondary implement and a link that is connected with the secondary implement. The header further has a lifting device with a slide element that is formed and connected with the link so that a translational movement of the slide element causes a lifting of the secondary implement relative to the primary implement.

Abstract: A stalked crop harvesting header include multiple harvesting units each including a set of deck plates defining a channel, a set of snapping rollers mounted below the deck plates and adapted to grasp and pull stalks downwardly through the channel, and a pair of gathering chains adapted for conveying stalks along the channel. Each harvesting unit further includes a stalk guider at either side of a front end of the channel. Each stalk guider includes an upper stalk guiding wheel and a lower stalk guiding wheel carried by a frame. The frame includes a protrusion between the upper and the lower stalk guiding wheels, which protrusion includes a support for carrying a respective front end of the snapping rollers.

Abstract: A feeder for a combine harvester, the feeder including a housing and a conveyor assembly mounted in the housing. The conveyor assembly includes a frame having lateral support arms, and moveable belts guided by sprocket wheels. The sprocket wheels are mounted on a drive shaft proximate an outlet section of the housing and on a conveyor shaft proximate an inlet section of the housing. The sprocket wheels are mounted on a drive shaft proximate an outlet section of the housing and on a conveyor shaft proximate an inlet section. The conveyor assembly is equipped with a first and second tensioning mechanism, the first mechanism being configured to push the conveyor shaft forward with respect to the frame, the second mechanism including spring-operated tensioning arms and tensioning rolls mounted above the support arms.

Abstract: A corn header includes a plurality of harvesting units to separate corn ears from corn stalks. Each harvesting unit has a deck plate assembly, and an actuator assembly to adjust a width of a stalk receiving channel by adjusting a position of at least a deck plate of the deck plate assembly. A kernel sensor can generate a signal representative of the presence of kernels detached from the ears during the separation of the corn ears from the corn stalks by the harvesting units and a control unit to receive the signal from the kernel sensor and generate an actuator control signal for controlling the actuator assemblies of the plurality of harvesting units, thereby controlling the width of the stalk receiving channels of the harvesting units.

Abstract: A corn ear harvester which comprises two deck plates and two gathering chain devices. The gathering chain devices each comprise an endless chain which forms a chain loop which comprises a straight operational part; a corn ear paddle and paddle connector which connects the corn ear paddle to the chain. The device further comprises a corn stalk channel having a deck plate channel section extends between the deck plates and a gathering chain channel section between the gathering chain devices. The deck plate channel section is too narrow for a corn ear to pass through. The corn ear paddles are arranged adjacent to a deck plate on the side of the ear blocking surface of said first deck plate and the endless chains of the gathering chain devices are arranged adjacent to the deck plates on the opposite side.
