An apparatus for attachment to a tractor the apparatus comprising a primary implement and at a first end, connections suitable to connect to the three point linkage of the tractor and at a second end, connections suitable to connect to the three point hitch points of a secondary implement.

An agricultural system for hydraulic flow control having an adjustable hydraulic fluid valve arranged between a hydraulic reservoir and a hydraulic consumer, pressure is measured at the reservoir-facing side and at the consumer-facing side of the valve, from which the fluid flow through the valve can be determined. The valve can then be easily controlled to provide a desired fluid flow level, regardless of the type of hydraulic circuit used.

A working machine includes a machine body, a lifting device to link a working device to the machine body, the lifting device being capable of moving up and down with the working device between a grounding state in which the working device is in contact with a ground and an ungrounding state in which the working device is out of contact with the ground, and an automatic travel controller to cause the machine body to perform automatic travel according to a planned travel route. The automatic travel controller includes a lifting controller to control the lifting device to move up with the working device from the grounding state to the ungrounding state, and cause the machine body to turn or travel rearward after the lifting controller controls the lifting device to move up with the working device from the grounding state to the ungrounding state.

An agricultural harvester includes a harvester body, a header which is adapted for harvesting a crop, a feeder house which is adapted to receive said harvested crop from the header, a header adapter which is arranged between the header and the feeder house, which header adapter is adapted to allow the header to pivot relative to the feeder house about a horizontal pivot axis substantially parallel to the longitudinal axis of the header. A first actuator has a first end that is pivotably connected to the feeder house and a second end that is pivotably connected to the header adapter. A second actuator has a first end and a second end, which first end is pivotably connected to the harvester body. A coupling device is pivotably connected to the second end of the second actuator, the feeder house and the header adapter.

A hydraulic system including a first cylinder conduit configured to couple to a cylinder, a second cylinder conduit configured to fluidly coupled to the cylinder, and a bypass conduit fluidly coupled both to the first cylinder conduit upstream of the cylinder and to the second cylinder conduit downstream of the cylinder. The bypass conduit is configured to enable intermittent fluid flow of a hydraulic fluid from the first cylinder conduit to the second cylinder conduit while bypassing at least a portion of the cylinder.

An agricultural vehicle includes a chassis (16), a lift arm (18) movably coupled to the chassis (16), a lift actuator (21) coupled to the lift arm (18), a header (14) coupled to the lift arm (18), and a controller (120) operably coupled to the lift actuator (21). The controller (120) is configured to: receive a header type signal corresponding to a header type of the header; define a lift height limit of the header based at least partially on the received header type signal, the lift height limit being a first height limit when a first header type signal is received or a second height limit when a second header type signal is received; and output a lift signal to the lift actuator (21) to vertically displace the header (14). Header vertical displacement is limited to the first height limit if the first header type signal is received or the second height limit if the second header type signal is received.

The present disclosure relates to an implement connectable to a working vehicle. The implement includes an arm, a fastening arrangement arranged at a first part of the arm, and an attaching arrangement connected to a second part of the arm. The fastening arrangement is connectable to the working vehicle. The attaching arrangement is attachable to a working tool. The implement further includes a first hydraulic circuit configured to carry hydraulic fluid to at least one first hydraulic function and a local control element. The implement further includes a digital interface to the working vehicle. The local control element is arranged to receive an operator control signal via said digital interface for operator control of the at least one first hydraulic function.

An apparatus and system for adjustably controlling the position and depth of row closer wheels in no-till planting applications, the apparatus comprising a frame, a piston movably secured at the top to the frame, upper and lower parallel arms disposed about the piston and movably secured at one end to the frame and at the other end to a hub stem, and a set of piston arms each movably secured at the top to one of the upper or lower parallel arms and at the other end to the bottom of the piston. A closing wheel assembly having a closing wheel frame and a set of closing wheels pivotally mounted to a lever on a single axle assembly allows the operator to change the angle at which the closing wheels intersect the ground surface during use. Accordingly, as the angle of the lever is manipulated, the angle of the closing wheel pivotally mounted to that lever changes in the vertical and/or horizontal dimensions.
