Systems, apparatuses, and methods include relate to an automatic header latch for an agricultural vehicle. The automatic header latch includes a housing link configured to couple a header to the agricultural vehicle, a channel formed in the housing link, a pin configured to be received through the channel, and a locking assembly coupled to the housing link. The locking assembly includes a rocking bracket, a diverting bracket hingedly coupled to the rocking bracket, and a fastener. The rocking bracket actuates between a loaded and an unloaded position, and is hingedly coupled to the diverting bracket. The fastener secures the rocking bracket in the loaded position, until the rocking bracket is actuated into the unloaded position by movement of the pin relative to the housing link. Following each full-raise actuation of the header, the automatic header latch is configured to alternate between a locked state and an unlocked state.

A coupling assembly for a three-point hitch of an agricultural tractor includes a lower link articulated on the tractor, a lift strut attached to the lower link, a catch hook at a free end of the lower link, the catch hook including a coupling body and a locking mechanism having a longitudinally movably mounted locking latch, a pull lever attached to the locking latch to deflect the locking latch, counter to a restoring spring force, out of a first locking position, which locks the catch hook, into a second locking position, which releases the catch hook, a deflection lever pivotably attached to the lift strut, and a first pull cable section connected to a free end of the pull lever and secured such that a pivoting movement at the deflection lever caused via a second pull cable section deflects the locking latch into the second locking position.

A draft link for a three-point hitch includes a longitudinal component, a first attachment end, a second attachment end, and a connector positioned on the second attachment end. The connector includes a first pin positioned within a first aperture of the connector and a second pin positioned within a second aperture of the connector. A first end of the first pin extends through an inner surface of the connector. A second end of the first pin extends through an outer surface of the connector. A first end and a second end of the second pin extend through an outer surface of the connector. The first pin forms an extension of an inner surface of the connector. The second pin is in contact with the first pin maintaining the position of the first pin.

A header is removably attached to lift arms of an agricultural harvester by mounting pins received in upwardly facing recesses on the ends of lift arms. A bar is moved into locking position by a lever arm mounted on the lift arms to hold the header mounting pins in place. A hook shaped latching device is pivotally mounted on the lift arm adjacent the lever arm for capturing it in place against the lift arm.

Self-propelled vehicles for supporting and operating a device are disclosed. Example devices include agricultural devices. The vehicle includes mounting arms that allow the device to be extended forward or rearward of the vehicle. In some embodiments, the device is releasably coupleable to the vehicle. In some embodiments, the vehicle includes rear drive wheels and front caster wheels.

A system includes an agricultural conveyor system including an inner arm having a first end. The first end is configured to rotatably couple to an agricultural storage system. The agricultural conveyor system also includes an outer arm having a first end, a second end, and a pivot positioned between the first end and the second end. In certain embodiments, the first end of the outer arm is coupled to a mounting element, a second end of the inner arm is rotatably coupled to the outer arm at the pivot, and an agricultural conveyor is configured to rotatably couple to the second end of the outer arm. The agricultural conveyor system includes a rotation control assembly. The rotation control assembly is configured to couple to the agricultural storage system. The agricultural conveyor system also includes an intermediate link having a first end engaged with the rotation control assembly and a second end. In some embodiments, the agricultural conveyor system includes a latching mechanism coupled to the second end of the intermediate link. A latch of the latching mechanism is configured to transition between a latched position and an unlatched position. In some embodiments, the latch captures the mounting element in the latched position and the latch releases the mounting element in the unlatched position.

A quick-coupling hook having a hook body, a securing lock, an actuating component coupled with the securing lock for common movement, a pre-tensioning spring, a first hook body-side abutment formation on a first side of the actuating component, and a second hook body-side abutment formation on a second side of the actuating component opposite to the first side, where the pre-tensioning spring extends between a hook body-side and an actuating component-side spring bearing and pre-tensions the actuating component towards its operating position, where the actuating component in its operating position abuts against the first and against the second hook body-side abutment formation, where it is provided that in a reference state of the quick-coupling hook, in which the actuating component is in an operating position and the securing lock in a decoupling-preventing securing position, a virtual straight connecting line passing through both the hook body-side spring bearing and the actuating component-side spring bearing of the pre-tensioning spring exhibits at least double the distance from the first hook body-side abutment formation as it does from the second hook body-side abutment formation.
