A hydraulic system for an agricultural system includes a hydraulic circuit and a bi-directional filter disposed on a bi-directional fluid line of the hydraulic circuit. The bi-directional filter includes a check valve fluid line having a check valve configured to block a fluid from flowing through the check valve fluid line in a first direction and to enable the fluid to flow through the check valve fluid line in a second direction, opposite the first direction, and a filter fluid line having a filter configured to enable the fluid to flow through the filter fluid line in the first direction and the second direction. The filter is configured to block particles that are greater than a threshold size from passing through the filter fluid line, and the filter fluid line is in a parallel flow configuration with respect to the check valve fluid line.

Systems and methods are provided for controlling operation of an agricultural vehicle-implement combination. An orientation of the vehicle, the implement and/or the vehicle-implement combination is used to determine whether an adjustment in a lateral position of the implement is required. An actuator mechanism is provided for controlling the lateral position of the implement in accordance with any determined adjustment.

An implement operating apparatus has a U-shaped drive frame supported on drive wheels, each pivotally mounted about a vertical wheel pivot axis. A steering control selectively pivots each drive wheel. A power source is connected through a drive control to rotate the drive wheels in either direction. First and second implements are configured to perform implement operations and to rest on the ground and when the drive frame is maneuvered to an implement loading position with respect to each implement, the implement is connectable to the drive frame and movable to an operating position supported by the drive frame. When the implement is in the operating position, the steering and drive controls are operative to move and steer the drive frame and implement along a first travel path or a second travel path oriented generally perpendicular to the first travel path.

An agricultural vehicle having a chassis, wheels, a power unit, and a header. The header has a center section, at least one wing section extending laterally from the center section, and a wing section support. The center section is movable relative to the chassis, the wing section is movable relative to the center section, and the wing support is movable relative to the wing section. The combine has a control system that is configured to determine that the combine is configured to drive at a road-driving speed, and in response to such determination: operate a center section actuator to move the center section to a raised center section position, operate a wing section actuator to move the wing section to a raised wing section position, and operate a wing support actuator to move the wing support to a raised wing support position.

A single solenoid-controlled electro-hydraulic liftomatic system is provided. The single solenoid-controlled electro-hydraulic liftomatic system is developed for controlling electrically, automating a hydraulic mechanism used in three-point hitch systems of tractors lifted and lowered by a mechanically controlled hydraulic mechanism. The single solenoid-controlled electro-hydraulic liftomatic system includes an actuator, a hydraulic pump, a safety element, a tank line, a valve body, a hydraulic piston, at least one solenoid valve, a piston spring, a check valve, a time-delay relay, and a button.

A working machine includes a vehicle body to which a working device is connectable, a driving estimator to estimate whether the vehicle body is drivable along a road based on a road condition and a device condition, a controller to control a driving operation of the vehicle body based on an estimation result obtained by the driving estimator, and a communicator to transmit to an external device driving information regarding driving the vehicle body under control of the controller. The controller is configured or programmed to drive the vehicle body based on a command received from the external device after transmission of the driving information from the communicator to the external device.

A control system for managing weight transfer along sections of a tractor drawn tool bar for use in row planting systems is provided. The planter weight transfer system comprises first and second assemblies 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. An improved PID-based WTS control system provides improved and balanced operation of agricultural machinery planting multiple rows with a multiple row planter units attached along a set of tool bars, wherein the wing sections and the center section of the tool bar complex are maintained in relative position by operation of the WTS and control system.
