A method is carried-out by a controller architecture coupled to a beam assembly actuator, which is included in an articulating tongue arrangement connecting an agricultural implement to a tow vehicle. In an embodiment, the method includes: (i) monitoring, via the controller architecture, an effective tow length of an articulating beam assembly further included in the articulating tongue arrangement, the effective tow length measured along a straight line extending from a leading pivot joint of the articulating tongue arrangement to a trailing pivot joint of the articulating tongue arrangement; (ii) determining, at the controller architecture, an effective tow length target of the articulating tongue arrangement based upon operator input, sensor input, or a combination thereof; and (iii) transmitting commands from the controller architecture to the beam assembly actuator to maintain the effective tow length of the articulating beam assembly in conformance with the effective tow length target.

A hitch device for an implement is capable of being mounted on an agricultural vehicle, including: a first chassis extending in a vertical plane, the normal to which is substantially the direction of travel of the hitch; a second chassis also extending in the vertical plane and mounted with capacity for translational movement on the first chassis in the transverse direction with respect to the direction of travel of the hitch; an actuator causing the translational movement of the second chassis with respect to the first chassis; an attachment device for fixing the first chassis to the rear of the agricultural vehicle; and a system for attaching an agricultural implement, the system allowing the implement to pivot about the vertical.

A towed agricultural implement includes one or more processing units each supported on a chassis, in which each chassis supports at least one processing unit on a central axis, the chassis having a left hand side wheel assembly support and a right hand side wheel assembly support, free ends of the wheel assembly supports having wheel assemblies, each wheel assembly comprising a wheel mounted on a wheel mount, the wheel mount being rotatable about an inclined axis, and the wheel being rotatable about a horizontal axis. The wheel assembly supporting structures and the wheel mounts allow limited relative movement of each wheel mount with respect to the wheel assembly supporting structures which enables greater control when the towed agricultural implement is towed about a corner.

A protection mechanism for a working vehicle includes a roof provided above an operator's seat, a pillar extending upward from a vehicle body and supporting the roof, a camera with a predetermined viewing direction, and a support stay which is connected to the pillar, orients the predetermined viewing direction of the camera sideways, and supports the camera below a peripheral portion of the roof. The protection mechanism includes a front pillar supporting a front portion of the roof and a rear pillar supporting a rear portion of the roof. The support stay is connected to the rear pillar.

A towed or semi-mounted agricultural machine having a chassis on which an axle device connecting two wheels to the chassis is mounted, this axle device being provided with at least one movable part and one fixed part in such a way that the spacing between the wheels can be modified, at least one of the wheels being integral with a movable part that is connected slidingly along a longitudinal axis to the fixed part, which is integral with the chassis. Each movable part is additionally connected mechanically to the chassis by a respective articulated link, which is articulated on the one hand with the movable part by a first articulation and on the other hand with the chassis by a second articulation.

A drawn agricultural implement includes a main frame and a plurality of ground engaging units supporting the main frame from a ground surface. A working unit is supported from the main frame and configured to engage crops as the implement moves in a forward direction across the ground surface. A draft tongue extends from the main frame for attachment to a tractor. A camera having a field of view is mounted on at least one of the draft tongue, the main frame and the working unit. The camera is movable relative to the at least one of the draft tongue, the main frame and the working unit to reposition the field of view.
