Walking track system of an agricultural implement

A control system for controlling an implement having a chassis that is movable between a work mode, at which the implement is configured to operate, and a transport mode, at which the implement is folded to be transported along a ground surface, the control system comprising:

• a controller comprising control logic for controlling the control system, the control logic including a predefined target height;
• a source of hydraulic fluid;
• a first actuator fluidly coupled to the source, the first actuator being movable between a retracted position and a fully extended position;
• a second actuator fluidly coupled to the source and in parallel with the first actuator, the second actuator being movable between a retracted position and a fully extended position;
• a sensor configured for detecting a change in height of the chassis as the first and second actuators move between their retracted and fully extended positions, the sensor being in communication with the controller;
• and
• a control valve disposed in communication with the controller and in fluid communication with the first and second actuators;
• wherein, as the implement moves to its transport mode, the sensor is configured to detects a height of the chassis relative to the ground surface and output the detected height to the controller;
• wherein, in response to being moved to its transport mode, the controller is configured to use the control logic to compare the detected height to the predefined target height;
• wherein, when the height of the chassis reaches the predefined target height as the implement is folded to the transport mode, the controller is configured to trigger the control valve to inhibit movement of the first and second actuators before either actuator reaches its fully extended position.

An agricultural implement configured to operate in at least a work mode, at which the agricultural implement is in a planting configuration, and a transport mode, at which the agricultural implement is in a transport configuration as it traverses along a ground surface, the implement comprising:

• a chassis;
• a first ground-engaging mechanism and a second ground-engaging mechanism coupled to the chassis;
• a source of hydraulic fluid;
• a first actuator fluidly coupled to the source and being movable between a retracted position and a fully extended position, the first actuator configured to move the first ground-engaging mechanism between a lowered position and raised position;
• a second actuator fluidly coupled to the source and in parallel with the first actuator, the second actuator being movable between a retracted position and a fully extended position, where the second actuator is configured to move the second ground-engaging mechanism between a lowered position and raised position;
• a sensor configured to detect a height of the chassis relative to the ground surface or movement of the first and second actuators;
• a control valve fluidly coupled with the first and second actuators;
• wherein, as the implement moves from the work mode to its transport mode, the sensor is configured to detect the height of the chassis or movement of the first and second actuators towards their fully extended positions;
• wherein, in response to the implement being moved from the work mode to the transport mode, the control valve is configured to inhibit movement of the first and second actuators before either actuator reaches its fully extended position.
