Abstract
An agricultural implement includes a transversely extending frame forming a first, a second, and a third frame section. A first actuator is coupled to the first frame section, a second actuator coupled to the second frame section, and a third actuator coupled to the third frame section. Sensors are coupled to each frame section to detect a height of the respective frame section relative to an underlying surface. A control unit is disposed in electrical communication with the sensors and operably controls the actuators to adjust the height of each frame section.
Claims25
A seeding implement including a plurality of tools for performing a work function, comprising:
- a multi-section frame including a first frame section, a second frame section, and a third frame section, where the first frame section is disposed between the second and third frame sections;
- a user control for communicating a desired tool depth of the plurality of tools;
- a first actuator coupled to the first frame section, a second actuator coupled to the second frame section, and a third actuator coupled to the third frame section;
- a first sensor coupled to the first frame section, the first sensor configured to detect a first height of the first frame section from an underlying surface;
- a second sensor coupled to the second frame section, the second sensor configured to detect a second height of the second frame section from the underlying surface;
- a third sensor coupled to the third frame section, the third sensor configured to detect a third height of the third frame section from the underlying surface;
- a control unit disposed in electrical communication with the user control, the first sensor, the second sensor, and the third sensor, the controller operably controlling the first actuator, the second actuator and the third actuator in response to the user control, the first sensor, the second sensor and the third sensor;
- wherein, the control unit compares the first height, the second height, and the third height to one another and determines if each height is equal to or within a threshold limit of one another;
- further wherein, when one of the first height, second height or third height is determined not to be equal to or within the threshold limit of the other two heights, the controller determines which frame section is uneven with the other two frame sections and actuates the actuator that is coupled to the uneven frame section until the first height, second height, and third height are equal or within the threshold limit of one another.
