An attachment mechanism for effecting a load-bearing interconnection between a header and a feederhouse of a self-propelled harvester is provided. The mechanism has a hook element secured to one of the header and feederhouse, the hook element having a limb defining an edge of a jaw opening with a inwardly tapering edge for longitudinally aligning and receiving a transverse pin secured to the other of the header and feederhouse. The limb has a non-vertical face configured to engage the other of the header and feederhouse and align such in the transverse direction as the feederhouse is lifted to engage the pin and jaw opening.

A quick joint of a front loader, the quick joint includes: a coupling member (30) having a hook shape and pivotally connected to a first pivot point (P1) of a boom post (20) through a first pivot shaft (31); a spring member (32) for applying an elastic force in a direction of releasing the coupling member (30) from a coupling target shaft (14) disposed on a boom post support (10) which is attached to a tractor (1); a lock unit (34) having a part making contact with the coupling member (30), and provided with a lock pin (36) for restraining behavior of the coupling member (30) at a coupling position (A1); and a guide slot (38) having an arc shape and formed in the boom post (20) to define a moving path of the lock pin (36) when the lock unit (34) rotates.

An agricultural work vehicle is operable to be advanced along the ground to sever a swath of standing forage plants and to lay the severed forage material into a windrow. The agricultural work vehicle includes a powered chassis, a harvesting header, and a quick-attachment header adapter. The header adapter is shiftably supported by the powered chassis and is configured to selectively support the harvesting header. The header adapter includes an adapter frame, having end supports and a center support, and a selectively actuatable latch assembly supported on the adapter frame. The latch assembly is associated with at least one of the supports to releasably secure the harvesting header to the adapter frame when the latch assembly is engaged and permit disconnection from the adapter frame when the latch assembly is disengaged.

A front-boom sprayer is provided that includes a boom center section and lift arm arrangement that provides a field of view below the boom when the boom is in a raised state that is substantially free of view obstructions from torque tube or other crosswise-extending components. The lift arm arrangement may provide different link tube geometries so that the respective left and right pairs of upper and lower lift arms align with each other in the line of sight of the in-cab operator.

A structure of a detachable front loader includes: a main frame; a boom; and a subframe unit that supports the boom. The subframe unit includes: a subframe; a guide that is disposed on the subframe and engages with the main frame; a lock bar that includes a pivot shaft disposed on the subframe, and a pivot shaft part; an operation tool that moves the lock bar from the restriction position to the release position against a first biasing force; and a locking tool that is supported by the subframe, moves between a locking position and an unlocking position, is biased in a locking direction, and once the operation tool moves the lock bar to the release position, moves to the locking position by a second biasing force, and engages with a cutout formed in the pivot shaft part.

A transport assembly for a harvesting head that includes head connector arms, a transport axle, and a coupling system with a latch actuator, and first and second latch mechanisms coupled to the latch actuator and located at opposite ends of the transport axle. The transport assembly functions in working and transport modes. In the working mode, the first and second latch mechanisms latch the first and second head connector arms to the transport axle to latch the harvesting head to the transport axle. When the latch actuator is activated, the first and second latch mechanisms release the first and second head connector arms from the transport axle to allow the harvesting head to separate from the transport axle. When the latch actuator is not activated, the first and second latch mechanisms can be biased to remain latched.

A hitch assembly may comprise a pair of fixed actuator support brackets that are mounted to a vehicle frame and a pair of modular actuator connection brackets that are connected to the pair of support brackets. The hitch assembly may further comprise a pair of lower links that are connected to the pair of fixed actuator support brackets and a cross bar that connects a first lower link of the pair of lower links to a second lower link of the pair. The hitch assembly may further comprise a pair of electric linear actuators that are connected to the pair of modular actuator connection brackets and the pair of lower links, as well as a top link that is at least pivotally connected to a top link bracket on the vehicle frame, in which the lower links are is moved by extension or retraction of the connected electric linear actuators.

An agricultural machine includes a controller disposed in communication with a implement linkage system, an output, and an input. The controller is operable to identify a selected work implement from a plurality of different work implements. A desired operating condition is then solicited from an operator via the output. A selection command is received from the operator via the input indicating which of a float operating condition and a fixed height operating condition is the desired operating condition. The controller may then automatically determine a recommended operating setting for the implement linkage system for the selected work implement and the desired operating condition and notify the operator of the recommended operating setting for the implement linkage system for the selected work implement and the desired operating condition via the output.

An attachment system for an agricultural vehicle including a feeder housing and a header. The attachment system includes at least one feeder connecting member configured for being located on and movably connected to the feeder housing, and at least one header connecting member configured for being located on the header. The at least one feeder connecting member is automatically connectable and securable to the at least one header connecting member as the feeder housing lifts the header.

A coupling device is disclosed which is designed as a hook with a hook body, an opening that allows the mating part of the attachment to enter the hook body, a guideway and a shoulder to counter any offset between the mating part of the attachment to the hook. Furthermore, the coupling device includes a locking latch that protrudes into the opening of the hook body and locks the mating part of the attachment in order to engage the mating part with the hook body, thereby retaining the mating part in a locked position. In an embodiment, the locking latch has a geometry that limits the motion of the locking latch and generates a motion curve. Furthermore, the locking latch moves on a motion curve to allow the locking latch to release the opening in order to allow the mating pan to enter the socket.
