In certain embodiments, an attachment system for a work vehicle may include a chassis interface coupled to a chassis of the work vehicle. The chassis interface may include a recess extending in a longitudinal direction and a pin retainer having a pin hole extending in a lateral direction. The recess receives a protrusion of an attachment interface coupled to an attachment. The pin hole of the pin retainer receives a pin and the pin fastens the chassis interface and the attachment interface to one another.

An autonomous agricultural system comprising an implement configured to perform an agricultural operation. The system additionally comprises an autonomous power unit for autonomously propelling the implement. The system further comprises a coupling assembly configured to connect the implement to the power unit. The coupling assembly provides at least six degrees of freedom of movement between the implement and the power unit.

The invention relates to an adjusting device, which includes a lifting device for adjusting a position of an attachment in use and a locking mechanism. The lifting device is switched between a locking position and a free position under a locking action of the locking mechanism, the lifting device drives the attachment to move to a first position when the lifting device is in the locking position; and the lifting device drives the attachment to move to a second position so as to work when the lifting device is in the free position. The adjusting device of the present invention has a simple structure, a low production cost, an easy maintenance, and a garden tool using the adjusting device can conveniently and quickly adjust the position of the attachment connected to the garden tool.

A boom center section for an agricultural machine includes a bulkhead haying a first end and a second end, at least one bulkhead opening located adjacent at least one of the first and the second ends of the bulkhead, and at least one connection assembly disposed within the at least one bulkhead opening. Each bulkhead opening is formed through a first wall of the bulkhead. Each connection assembly includes a plurality of connectors.

A coupling device, particularly for power-operated machines for agricultural use or the like, includes an oscillating frame which is detachably connected to a hitch assembly of an engine and a movable connection for associating with the oscillating frame the working means of a power-operated machine. The oscillating frame and the movable connecting means are configured to maintain, during use, the working plane of the power-operated machine substantially parallel to the ground, independently of the plane of arrangement of the wheels or of the tracks of the engine.

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.

An apparatus, system, and method of securing attachments to a utility vehicle, particularly a stand-on, zero-turn mower. The apparatus includes an A-shaped mounting assembly having a base with first and second ends and a tubular member extending outwardly from the first end. The tubular member defines a bore that receives a shaft extending from the attachment. The mounting assembly is positioned vertically above a mower deck on an opposite side of the frame of the mower relative thereto. The second end of the mounting assembly and part of the mower deck are secured to the frame using the same connectors. A hydraulic actuator engages a forwardmost end of the assembly and is actuatable to raise or lower the assembly relative to the frame, pivoting the assembly about the connectors. The attachment and mower deck are substantially simultaneously operable to perform separate landscaping tasks while the mower moves across a surface.

A plow conversion kit includes a frame having a frame proximal end, a frame distal end, and a top surface extending between the proximal end and the distal end. A fixed bracket is fixed to the top surface of the frame. The fixed bracket has a fixed bracket proximal end and a fixed bracket distal end. A hydraulic cylinder has a cylinder proximal end pivotally connected to the fixed bracket and a cylinder distal end extending distally of the fixed bracket. A mounting bracket has a lower end pivotally connected to the fixed bracket distal end. A mount arm has a lower end pivotally connected to the mounting bracket. A pivot bracket has a lower end pivotally connected to the frame distal end, a central portion pivotally connected to the cylinder distal end, and a top end connectable to an upper portion of the mount arm.

A work vehicle (1) comprises a coupling apparatus (18) for coupling an attachment to the forward end (8) of the work vehicle (1). The coupling apparatus (18) comprises a three point linkage mechanism having a pair of lower coupling elements (19) and an upper coupling element (25). A first carrier element (22) is pivotally coupled to a forward chassis part (14) of the work vehicle (1) by a pair of main transverse pivot shafts (35) which define a main transverse pivot axis (33). A second carrier element (23) carries the lower coupling elements (19) and is pivotally coupled to the forward chassis part (14) about the main transverse pivot axis (33) and about a main longitudinal pivot axis (45). A main longitudinal pivot shaft (46) extending rigidly from the second carrier element (23) pivotally engages the first carrier element (22) and terminates in a swivel bearing (50) which pivotally and swivelably couples the main longitudinal pivot shaft (46) to an intermediate transverse pivot shaft (54) which also defines the main transverse pivot axis (33), so that the second carrier element (23) and the first carrier element (22) are pivotal about the main transverse pivot axis (33), and the second carrier element (23) is pivotal about the main longitudinal pivot axis (45) to facilitate upward and downward movement of an attachment coupled to the coupling apparatus (18) about the main transverse pivot axis (33) and tilting movement of the attachment about the main longitudinal pivot axis (45).

A mast coupling arrangement for mounting a front loader to a work vehicle at a mounting frame defining connection points and a load point includes a mounting bracket mounted at an end of a mast of the front loader, and a first mast connector removably coupling the mounting bracket and one of the connection points of the mounting frame when the front loader is attached. The mast coupling arrangement includes a load element mounted to the mast that, when the front loader is attached, is in load transferring contact with the load point of the mounting frame. The mast coupling arrangement includes a second mast connector removably coupling the mounting bracket and another of the connection points of the mounting frame when the front loader is attached to. The second mast connector and the associated connection point of the mounting frame are separable when the front loader is attached.
