An agricultural work system has an agricultural work machine to which at least one mounted implement can be fitted via at least one implement interface. A work machine configuration is associated with the work machine, and a mounted implement configuration is associated with the mounted implement. A drive unit is provided which acts via a drivetrain on ground engaging elements, particularly on tires. A system control and a control/display unit associated with the work machine are provided. It is proposed that the system control is adapted to determine the mounted implement configuration, to calculate the implement interface load transmitted via the implement interface based on the determined mounted implement configuration, and to evaluate and/or optimize the work machine configuration based on the calculated implement interface load.

A front mower for mounting on a front three point linkage of a tractor to be operated for cutting vegetation, such as grass, in front of the tractor, the mower comprising: (i) a headstock for mounting on the front three point linkage of the tractor; (ii) a mowing head comprising an array of cutting heads for cutting vegetation such as grass, mounted on and moveable relative to the headstock to follow the contours of the ground over which the mower is passing; (iii) a mounting mechanism mounting the mowing head to the headstock, wherein the mounting mechanism comprises a cutting angle adjustment mechanism comprising an arc shaped guide and a follower for the arc shaped guide, the follower being moveable back and forth along the arc shaped guide, so that the cutting angle adjustment mechanism allows the mowing head to move back and forth along an arc defined by the guide and relative to the headstock so as to vary the cutting angle of the cutting heads. This allows for free movement of the mowing head to follow the contours of the ground.

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 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 tangible non-transitory computer readable medium includes instructions that, when executed by a processor, are configured to cause the processor to detect a movement state of an agricultural implement and automatically retract a stabilizer of a stabilization system from an extended position to a retracted position in response to detecting the movement state of the agricultural implement. The stabilizer is connected to a rear portion of a frame of the agricultural implement, and the stabilizer is configured to support a weight of the rear portion while in the extended position.

A method for determining a mass of an implement includes providing a rear powerlift having at least one upper link and at least one lower link and a support structure disposed at the rear of a utility vehicle. The method includes defining an angle (Ψ) between the upper link and a vehicle horizontal line, an angle (φ) between the lower link and the vehicle horizontal line, an angle of inclination (θ) of a vehicle horizontal line relative to a terrestrial horizontal line, a path (LV) representative of a connection along the lower link between the support structure and the implement, and a force (F.sub.U) impinging on a connection between the upper link and the implement and acting along the upper link. The mass is determined by at least one of the angle (Ψ), the angle (φ), the angle of inclination (θ), the path (LV), and the force (F.sub.U).
