Actuator On Vehicle For Moving Wheeled Implement Patents (Class 172/321)
  • Patent number: 11849660
    Abstract: A tillage implement has a frame with a center section and first and second outer wing sections hingedly attached the center section such that the wing sections can be operably raised and lowered between a field-working position and a transport position. The sections each carry tillage tools for working the soil. Controlling a precharge in a secondary side of a hydraulic circuit enables the operator of the implement to adjust the downward pressure precharge provided by a plurality of hydraulic cylinders based on a desired stiffness of the implement. A pressure-reducing valve is configured such that flow from the hydraulic supply applies downward pressure precharge on the plurality of tillage tools. Once this desired precharge has been achieved, flow from the hydraulic supply is shut off and a check valve holds the pressure such that the plurality of hydraulic cylinders holds the tillage tools in position.

  • Patent number: 7003386
    Abstract: The invention relates to a device and to a method for determining the position for a working part of a tool on a working machine with a position-determining apparatus (2, 4, 5, 6; 2, 4a, 4b, 5, 6?; 31, 33, 49, 50, 51, 1?,53). At least one detector equipment (4, 5, 6; 4a, 4b, 5, 6?; 31, 33; 49, 50, 51, 53) is placed at a defined place on the working machine (3; 52) in order to determine the position of this position in a fixed coordinate system. At least one positional relationship device (11) determines the positional relation of the working part in relation to the detector equipment in a machine-based coordinate system. A calculating device (20) calculates, with signals from the position-determining apparatus and the positional relationship device, the position of the working part in the fixed coordinate system.

  • Patent number: 5687798
    Abstract: The implement has a folding tool-bar, with a main section and wings. Hydraulic rams press the wings downwards relative to the main section during operation. Another ram presses the main-section downwards, reacting the force against a relatively weighty component, such as a air-cart. During non-operation, a carriage wheel is lowered, which raises the main section of the tool-bar off the ground. The wings also are raised clear of the ground. A sensor detects the position of the carriage wheel, and blocks movement of the wings downwards when the carriage wheel is lowered.

  • Patent number: 4920732
    Abstract: Lift structure particularly useful with front mounted implements for providing both lift and weight transfer functions from a single valve. The valve acts as an adjustable bleeder for the lift cylinder and includes a control knob which is movable both axially and rotationally to respectively provide lift and adjustable flotation. The valve is normally biased to an adjustable orifice position for operating the implement in a lowered, flotation position. To momentarily lift the implement, the operator moves the control knob against the bias to direct flow to the lift cylinder thereby raising the implement off the ground. When the operator releases the valve, it automatically returns to the preset orifice position to provide the desired flotation.
