A three-point hitch for an agricultural tractor includes a hydraulically actuatable lifting arm, a vertically pivotable lower link, and a lifting strut arranged between the lifting arm and the lower link. The lifting strut transmits to the lower link a pivoting movement on the lifting arm. The lifting strut includes a first fastening portion articulated to the lifting arm and a second fastening portion articulated to the lower link. The second fastening portion includes first and second fastening segments which encompass the lower link in a fork-shaped manner. A bearing pin disposed between the two fastening segments extends through a slot formed in the lower link. By pivoting the lower link, the bearing pin is displaced inside the slot between a first working position and a second working position. In each position, the bearing pin is secured inside the slot by a blocking arrangement.

A vehicle connection guidance system may include a sensor and a controller. The sensor is configured to be supported by a vehicle having a first width and a connection interface, the connection interface having a second width different than the first width and along which multiple connection points lie, wherein the sensor is to output steering angle signals. The Controller is configured to output presentation signals based upon the steering angle signals The presentation signals are to generate a visual presentation of a projected path of the width of the connection interface to an operator of the vehicle.

A vehicle attachment carrier loading guidance system may include a sensor for being supported by vehicle supporting a removable attachment having a mount interface for interacting with a mount on an attachment carrier distinct from the vehicle, wherein the sensor is output steering angle signals. The system may further comprise a controller to output presentation signals based upon the steering angle signals. The presentation signals are to generate a visual representation of a projected path of the mount interface with respect to the mount.

An implement operating apparatus has a U-shaped drive frame supported on drive wheels, each pivotally mounted about a vertical wheel pivot axis. A steering control selectively pivots each drive wheel. A power source is connected through a drive control to rotate the drive wheels in either direction. First and second implements are configured to perform implement operations and to rest on the ground and when the drive frame is maneuvered to an implement loading position with respect to each implement, the implement is connectable to the drive frame and movable to an operating position supported by the drive frame. When the implement is in the operating position, the steering and drive controls are operative to move and steer the drive frame and implement along a first travel path or a second travel path oriented generally perpendicular to the first travel path.

An apparatus for combining planting implements enables an operator of a tractor to use both a conventional cultivating implement and a conventional broadcasting implement simultaneously. The apparatus is rigidly affixed to a conventional cultivating implement and comprises a support frame, a pair of brackets, and a connection bar. In combination, the support frame, pair of brackets, and connection bar provide a three-point connection whereby a conventional broadcasting implement may be attached thereto, thus enabling an operator of a tractor to use both a conventional cultivating implement and a conventional broadcasting implement simultaneously. In operation, at least a portion of the conventional cultivating implement is disposed behind the conventional broadcasting implement when the conventional broadcasting implement is attached to the support frame, thereby allowing simultaneous cultivation and broadcasting of constituents.

The invention concerns an air-moving device (10) for pollinating at least one recipient plant using pollen collected on at least one donor plant, comprising: a means (12) for collecting pollen from said at least one donor plant, a means (14) for distributing pollen on at least one recipient plant, a channel for conveying the pollen collected from the collecting means (12) to the distributing means (14), an air flow amplifier (18) which employs Coanda effect for inducing a flow of air inside the conveying channel (16) from the means (12) for collecting the pollen to the means (14) for distributing the pollen.

The invention also concerns a pneumatic deflector for deflecting the Coanda effect flow of pollen disposed at the level of the pollen distributing means (14).

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 mower system comprising a powered mower, a connecting device connected to the powered mower and an attachment connected to the powered mower through the connecting device for conducting specified function during the operation of the mower system. The connecting device includes a mounting assembly mounted to the powered mower and a base rotatably mounted to the mounting assembly for driving the attachment being rotated together with the base in a horizontal plane relative to the powered mower. The utilization rate of the powered mower is effectively improved because other working functions can be conducted by the attachment which is connected to the powered mower through the connecting device.

A lifting device for platforms carrying a load is disclosed. A winch or piston is engaged with two vertical arms connected to two horizontal arms configured for attaching to a load carrying assembly such that exerting an upward force on the two vertical arms causes the horizontal arms to pivot upward to lift the load carrying assembly which enables transporting the platform and the load on it to another location. The lifting device is configured to quickly attach to and detach from the load carrying platform and for maintaining a level position during transportation. The horizontal arms are configured for retracting and extending which enables the tilting of the load carrying assembly backward or forward as needed for improved transportation stability and load discharge.
