In one aspect, a system for controlling the speed of an agricultural implement may include a work vehicle including a vehicle-based controller, with the vehicle-based controller being configured to adjust a drive parameter of the work vehicle. The system may also include an agricultural implement configured to be towed by the work vehicle. The implement may include a sensor configured to detect an operational parameter indicative of an orientation of the implement relative to the work vehicle. The implement may further include an implement-based controller supported on the implement and being communicatively coupled to the sensor. The implement-based controller may be configured to initiate control of the drive parameter of the work vehicle based on sensor data received from the sensor in a manner that adjusts the speed of the implement.

A quick disassembly tool for fixedly mounting a connection module is provided according to the present application, including a pressing block and a fixing block for press-fitting the connection module. A press-fitting end face of the fixing block is provided with a press-fitting hole, and a press-fitting post inserted into the press-fitting hole protrudes from the pressing block; the quick disassembly tool further includes a locking device respectively pressing on an end of the pressing block and an end of the fixing block, and the locking device includes an elastic pressing device configured to adjust a press-fitting space between the pressing block and the fixing block. The pressing block and the fixing block are connected and transversely position-limited through the press-fitting hole and the press-fitting post, the locking of the pressing block and the fixing block in a pressing direction is achieved by a locking device.

A hitch that connects to a chassis of the work vehicle and rotates with respect to the chassis includes a first bracket connected to a first portion of the chassis, a first stabilizer bar connected to the first bracket, and a first hitch arm connected to the first stabilizer bar. The first hitch arm has a free end that engages a work implement. A second bracket is connected to a second portion of the chassis. The second portion of the chassis is spaced from the first portion of the chassis, so that the second bracket is spaced apart from and independent of the first bracket. A second stabilizer bar is connected to the second bracket. A second hitch arm is connected to the first stabilizer bar. The second hitch has a free end configured to selectively engage the work implement.

The turning radius of a differentially steered vehicle towing a trailer is controlled when turning so that its turning radius is greater than a minimum allowable turning radius. The turning radius may be autonomously adjusted using a controller to monitor the instantaneous rotational speed differential between the driven wheels and increase or decrease the relative speed between the wheels when the instantaneous rotational speed differential exceeds a threshold rotational speed differential, indicating a turn which is too tight. Alternately, the turning radius may be controlled by the vehicle's operator, who receives a signal from the controller indicating that the vehicle's turning radius is less than the minimum allowable. The operator may then take action to enlarge the turning radius using manual controls.

An agricultural vehicle-trailer combination includes a traction module including a drive element for engaging in a ground, a working appliance coupled to the traction module by a coupling apparatus, and a folding axle supporting the working appliance relative to the ground at least during a transport mode. A slewing mechanism of the coupling apparatus provides a degree of freedom of rotation between the traction module and the working appliance along a longitudinal axis of the working appliance. A pivot joint provides a degree of freedom of pivoting between the traction module and the working appliance along a vertical axis of the traction module. The pivot joint is adjustable relative to its pivot angle by a steering actuator for influencing the direction of travel of the vehicle-trailer combination.

A laterally movable carrier is associated with a row frame. The carrier is connected to a frame member, an opener, a first outlet and a second outlet to allow for dynamically variable adjustment of the lateral separation between a first row of planted seed and a second row of planted seed, where the first row of seed is adjacent to the second row of seed.

An arrangement for controlling a hydraulic three-point hitch includes a double-acting hydraulic cylinder and first and second seat valves. The double-acting hydraulic cylinder has a first working chamber, by which pressurized hydraulic fluid can change the lifting position of a lower arm of the hydraulic three-point hitch, and a second working chamber connected to a control valve arrangement, by which a specified target pressure can be set in the second working chamber. The first and second seat valves are in fluid communication with the working chamber. The first seat valve selectively produces a flow connection to a high-pressure source. The second seat valve selectively produces a return connection to a hydraulic reservoir.

A data processor determines whether a draft force on the implement is unbalanced based on an error between the observed implement angle and a target implement heading exceeding a threshold deviation. The data processor is adapted to generate a control signal to compensate for the imbalance in the draft force by adjusting the first lateral position via the first actuator, or by adjusting the second lateral position via the second actuator, the first actuator and the second actuator being positioned on opposite lateral sides of the implement.
