Systems and methods provide automatic assignment of control of a plurality of hydraulic circuits of an associated work vehicle to a plurality of operation systems of an implement. A hydraulic circuit assignment control unit includes a processor, a memory device, logic stored in the memory device, and a communication circuit operatively coupled with the processor. The processor executes the logic to associate an activation of a first hydraulic circuit of the plurality of hydraulic circuits of the associated work vehicle with a physical exercise of an operation system of the plurality of operation systems of the associated implement, and generates pairing assignment data representative of the association of the activated first hydraulic circuit with the physical exercise of the operation system of the implement. The logic generates directionality confirmation and calibration data that is communicated to the plurality of operation systems with the pairing assignment data.

Agricultural tool-holder having a central chassis with a coupling system for coupling with a tractor and at least one lateral chassis that can slide closer to or away from the central chassis, which has a longitudinal axis and includes an adjacent parallel pair of tubular beams orthogonal to the longitudinal axis and suitable for slidingly receiving two rods provided in the lateral chassis, moved by a main actuator mounted in the central chassis.

A cultivator function is coupled with a scraper function in a single implement such that the cultivator portion and the scraper portion of the combination farming implement, when attached to a vehicle, can be mechanically and remotely changed out at any time. The cultivator portion and the scraper portion of the combination farming implement are positioned on opposite sides of a rotating framework, such that the combination farming implement can be mechanically and remotely rotated during use in the field, thus enabling the performance of both the cultivator function and the scraper function without a vehicle operator ever leaving the vehicle.

Agricultural implements and hydraulic circuits for agricultural implements are disclosed herein. An agricultural implement includes a fluid source, a plurality of fluid demand devices, a delivery control valve, and a priority valve. The fluid source is configured to supply hydraulic fluid. The plurality of fluid demand devices are each configured to receive hydraulic fluid supplied by the fluid source during operation of the agricultural implement. The delivery control valve is fluidly coupled between the fluid source and a first fluid demand device. The delivery control valve is configured to selectively deliver hydraulic fluid supplied by the fluid source to the first fluid demand device during operation of the agricultural implement. The priority valve is fluidly coupled between the delivery control valve and the first fluid demand device.

A coupling device for attaching a power lift of a tractor to an attachment includes a link mounting region having coupling units for the articulation of an upper link and two lower links of the power lift, and an apparatus mounting region for fixing the attachment. A coupling unit assigned to the upper link is movable in a translatory manner in a vertical direction running perpendicular to a transverse direction. The coupling units are movably disposed on a device base of the coupling device, and the coupling units assigned to the two lower links are movable in a translatory manner in the transverse direction.

A rod weeder wherein the rotatable rod is provided as a quick-change rod assembly comprising the rod and rod shoes for being mounted to the rod shanks resulting in the ability to quickly release and change the quick-change rod assembly from the tool frame and the remainder of the implement. Optionally, the rod weeder may comprise disk openers placed in proximity to the gauge wheels, or the support beam may be pivotally movable mounted to the connecting structure such that the same is enabled to oscillate about an axis through a centre pivot and oriented parallel to a forward moving direction of the rod weeder.

A land vehicle comprises first and second wheel motors that control respective rates of rotation of left and right rear wheels. An accelerator adjustment assembly controls the first and second wheel motors and comprises first and second linkage assemblies that cause the rate of rotation of an inside rear wheel to slow during a turn exceeding a predetermined turning radius. In preferred embodiments, the land vehicle is a sweeper machine comprising a debris collection assembly, a hopper, and a hydraulic cylinder adapted to lift and lower the debris collection assembly. The debris collection assembly comprises a collection body, a brush adjustment assembly, and a rotary brush assembly. The brush adjustment assembly comprises a height adjustment lever and an actuator comprising a piston rod. The piston rod is adapted to raise and lower a first end of the height adjustment lever such that the rotary brush assembly is raised and lowered.
