An agricultural machine is coupled to a tractor vehicle and includes a work unit connected to a chassis relative to which the work unit can be moved, the machine being able to take up a work configuration and a transport configuration. The machine includes a lightening device having a lightening cylinder connected to the chassis by a flexible compression tie-rod on one side and to the work unit at a front articulation on the other side, the lightening cylinder being able to transfer, in the work configuration, some of the weight of the work unit onto the chassis, the flexible compression tie-rod being attached with the lightening cylinder at an anchoring point and with the chassis at a fastening point, a deflection system making it possible to move the lightening cylinder by pivoting the anchoring point about the front articulation so as to move it away from the midplane.

An removably installable apparatus and system for managing weight transfer along a tractor drawn tool bar for use in row planting systems is provided. The planter weight transfer system comprises first and second bolt-on bracket assemblies, each bolt-on bracket assembly comprising a primary plate and a secondary plate secured to each other and to a row planter tool bar by a set of fasteners. Additionally, the bolt-on brackets are joined at the top by an actuator which applies a force on the brackets.

A control system for controlling an implement that is movable between a work mode and a transport mode. The control system includes a source of hydraulic fluid, a first actuator and a second actuator. The first and second actuators are fluidly coupled to the source and disposed parallel to one another. A sensor detects movement of the first and second actuators between their retracted and fully extended positions, and a control valve is disposed in communication with the sensor and in fluid communication with the first and second actuators. As the implement moves to its transport mode, the sensor detects movement of the first and second actuators towards their fully extended positions. The control valve inhibits movement of the first and second actuators before either actuator reaches its fully extended position.

A force sensor is suitable for an electrohydraulic hitch control system of an agricultural tractor. The force sensor has an outer cylindrical part with a bore and a measuring rod fixed on one side in the bore. A central section of the cylindrical part is provided as force introduction section. Two outer sections of the cylinder part are removed equally far axially from the center of the force introduction section and are provided as abutment sections. The measuring rod is clamped in an area of the force introduction section.

An agricultural implement towable by an agricultural vehicle. The agricultural implement includes a frame with a front portion and a rear portion, a plurality of ground engaging tools connected to the rear portion, and a stabilization system. The stabilization system includes at least one stabilizer connected to the rear portion. The at least one stabilizer is remotely operated for selectively supporting the rear portion relative to the front portion and leveling the frame.

A draft load control system for an agricultural implement includes a row unit, a down force system configured to apply a force within or to the row unit, a draft load sensor disposed on the row unit and configured to generate a sensor signal indicative of a draft load on the row unit, and a controller that includes a memory and a processor. The controller is configured to receive the sensor signal from the draft load sensor indicative of the draft load on the row unit, and in response to the draft load exceeding a threshold range, perform a control operation, a monitoring operation, or both.
