The invention relates to a self-propelled agricultural machine, for example a self-propelled merger, which self-propelled agricultural machine is provided with at least one motor, at least two elongate units for, in use, performing an agricultural operation on the land, a front wheel axle and a rear wheel axle situated at a distance from the front wheel axle, wherein the front wheel axle and/or the rear wheel axle can be driven by means of the motor for displacing the agricultural machine, wherein each elongate unit is displaceable from a transportation position to a working position and vice versa by means of a folding mechanism, so that the maximum width of the self-propelled agricultural machine is smaller in the transportation position of the units than in the working position of the units, wherein, in the working position, the agricultural operation on the land can be performed substantially along the length of each elongate unit.

Plant scanning vehicles (10) including, but not limited to, plant scanning vehicles for use in field-based phenotyping. There is a central body (16); three or more legs (15) extending from the central body (16) to support a wheel (13) on each leg (15); wherein the three or more legs (15) are mounted to the central body (16) rotatably about a respective vertical axis (95) to allow adjustment of a track width W of the vehicle by rotating the legs wherein the legs are mechanically coupled to transmit rotation between the legs about their respective vertical axes and the central body (16) or the three or more legs (13) are configured to support a sensor (47) to scan plants.

An implement for traversing a field includes a main frame section and a frame wing section pivotally coupled to the main frame section. The frame wing section includes a wing wheel assembly for supporting the frame wing section. A hydraulic control system includes a pressure source, a control valve fluidly coupled with the pressure source, and an actuator assembly fluidly coupled to the control valve. The implement further includes a controller electrically coupled with the control valve. A wheel force sensor is configured to detect an amount of force on the wing wheel assembly and communicate the amount of force to the controller. The actuator assembly is coupled between the main frame section and the frame wing section. The controller operably controls movement of the control valve to actuate the actuator assembly and adjust the amount of force on the wing wheel assembly.

A method for reducing an overall transport profile of a multi-section tillage implement. The tillage implement may include a frame including a center frame section and at least one wing frame section. The tillage implement may include a plurality of ground-engaging tools pivotally mounted to the frame. The method may include pivoting each of the plurality of ground-engaging tools away from the ground surface from a ground-engaging position to a retracted position. The frame may be disposed at an initial height relative to the ground surface before pivoting. After pivoting, the frame may be lowered to a transport height relative to the ground surface. At least one wing frame section may be folded relative to the center frame section from an operating position to a transport position to reduce a width of the tillage implement in the widthwise direction.

An implement frame having a carriage frame for coupling to a towing vehicle and wheels to support the frame for movement over a ground surface. A pivot frame is rotationally mounted to the carriage frame and a lift assembly is coupled to the pivot frame via a shift assembly. A tool bar is mounted to the lift assembly. The shift assembly moves the tool bar forward as it is moved from the field use position to the transport position. The wheels are mounted to swing arms to move the wheels inward for a narrow transport position.

A tillage implement has a frame with a center section and first and second outer wing sections hingedly attached the center section such that the wing sections can be operably raised and lowered between a field-working position and a transport position. The sections each carry tillage tools for working the soil. Controlling a precharge in a secondary side of a hydraulic circuit enables the operator of the implement to adjust the downward pressure precharge provided by a plurality of hydraulic cylinders based on a desired stiffness of the implement. A pressure-reducing valve is configured such that flow from the hydraulic supply applies downward pressure precharge on the plurality of tillage tools. Once this desired precharge has been achieved, flow from the hydraulic supply is shut off and a check valve holds the pressure such that the plurality of hydraulic cylinders holds the tillage tools in position.

An agricultural toolbar employs at least two wing assemblies for following the contour of the land in a working position and foldable to a transport position for transit on public roads. The principal use in working position benefits from having a wide range of movement to accommodate variations in land contours and soil types. The principal use in transport mode benefits from having a compact configuration to better meet road regulations. End-uses that condition cultivatable land at multiple locations will benefit from the toolbar.

A spray boom support structure includes a first support member, a second support member, a plurality of vertical support elements disposed between the first and second support member along lengths of the first and second support members, and at least one strut. Each vertical support element includes a bottom saddle portion coupled to first support member, a top saddle portion coupled to the second support member, and an I-beam portion disposed between the top and bottom saddle portions. Further, each strut extends between adjacent vertical support elements.
