A trailer device for an agricultural vehicle includes a frame part and a guide part longitudinally, displaceably mounted in the frame part. The guide part includes a coupling element provided on an end face. The frame part is pivoted by a lifting apparatus for raising and lowering the coupling element relative to a base frame for attaching to a load-bearing vehicle structure. The device includes at least one spring element arranged between the base frame and the frame part such that the spring element exerts a pretensioning force on the frame part for assisting the raising of the coupling element.

A driver assistance system for controlling a combination of agricultural vehicles including a towing vehicle designed as a tractor and a mounted device, wherein the driver assistance system generates control parameters for the towing vehicle and/or for the mounted device. The driver assistance system has an input/output unit for the dialog with the user. The driver assistance system is formed by a rule interpreter which generates the control parameters by executing the rules of a set of rules, and the driver assistance system has a linking module which receives at least two sets of rules from different data sources and generates, on the basis of the received sets of rules and according to a linkage specification, the set of rules to be executed by the rule interpreter.

An agricultural support system includes an unmanned aerial vehicle including a sensor, and an agricultural machine to travel in an agricultural field. When an abnormality occurs in the unmanned aerial vehicle while the agricultural machine performs work in the agricultural field in cooperation with the unmanned aerial vehicle, the unmanned aerial vehicle or the agricultural machine performs an operation different from an operation during the work.

A hitch configured to selectively latch to a tow bar is provided. The hitch includes a housing, a frame defining a receiving cavity, a moveable arm, an actuator configured to move the arm between an unlatched position and a latched position, and a contact sensor mounted within the housing on a slotted mounting plate. The arm is configured to engage the tow bar when in the latched position. The slotted mounting plate is configured to enable a position of the contact sensor to be adjusted based on a geometry of the tow bar. The actuator is activated by the contact sensor sensing the presence of the tow bar within the receiving cavity.

A trailer brake system that generates load-dependent braking forces. Variable trailer load information is used to generate load-dependent control signals which serve to control an electrically-controlled proportional valve. A load sensing valve serves to modify brake command signals in dependence on a control pressure that is regulated by the proportional valve.

Systems and methods are disclosed herein for navigating an operator of a self-propelled vehicle for coupling with an attachment implement therefor. Each one of a first set of sensing elements arranged on the vehicle coupler forms a sensing pair with a respective one of a set of second sensing elements arranged on the attachment implement. Indicia for each of the sensing pairs on a user interface is displayed to the operator, corresponding to a three-dimensional spatial orientation of the first and second sensing elements with respect to each other. The user interface may comprise respective portions for each sensing pair, each portion comprising an indicator dynamically adjusted in a crosshair corresponding to first and second dimensions of alignment of the corresponding sensing elements with respect to each other, and the indicator in each portion further dynamically adjusted in appearance corresponding to a third dimension of distance between the corresponding sensing elements.

A vehicle mounted articulating snow plow apparatus is provided for clearing snow from roads and driveways. The snow plow includes a blade assembly having a center blade and an extendable wing blade coupled to each end of the center blade. The blade assembly can be raised and lowered relative to the vehicle and ground surface and can be rotated about a vertical axis. Each extendable blade is independently pivotable relative to the center blade through an arc of greater than one-hundred eighty degrees (180°) about a vertical axis. The blade assembly is extendable and retractable between at least a stowed configuration, wherein the extendable blades extend laterally inboard alongside the center blade, and a linearly extended configuration, wherein the extendable blades are outboard of the center blade. The blade assembly includes an actuation mechanism to pivot the extendable blade relative to the center blade.

The present invention relates to a coupling device (1) for mechanical coupling and media supply between a carrier vehicle (41) and a superstructure (42), having a coupling mechanism (10) for establishing a mechanical coupling between the carrier vehicle (41) and the superstructure (42) and a media mechanism (20) for establishing a media supply between the carrier vehicle (41) and the superstructure (42), which are operatively connected with each another via an operating mechanism (30). The coupling mechanism (10) is mounted so as to be moveable between at least one first coupling position at least partially forming the mechanical coupling and a release position releasing the mechanical coupling. The media mechanism (20) is also mounted so as to be moveable between a supply position forming the media supply and a shut-off position shutting off the media supply. The operating mechanism (30) has at least one guide means (31) for a forced guidance of the media mechanism (20) from the shut-off position into the supply position on a movement of the coupling mechanism (10) from the release position into the first coupling position. The invention also relates to an agricultural working vehicle (40) and a method for mechanical coupling and media supply between a carrier vehicle (41) and a superstructure (42).
