Abstract
A plough comprising: a frame; a ground engaging tool that is connected to the frame; and an actuator mechanism that is configured to control a roll angle and/or a pitch angle of the frame. The plough also includes a controller that is configured to: receive ground-contour-data that is representative of contours of a field that the plough is to work; and determine an actuator-control-signal for the actuator mechanism based on the ground-contour-data, wherein the actuator-control-signal is for setting the roll angle and/or the pitch angle of the frame.
Claims18
A plough comprising:
- a frame;
- a ground engaging tool that is connected to the frame;
- an actuator mechanism configured to control a roll angle of the frame, wherein the actuator mechanism comprises a turning actuator coupled to the frame and to a headstock of the plough, and the turning actuator is configured to rotate the frame about a longitudinal axis relative to the headstock to control the roll angle of the frame;
- and
- a controller configured to:
- receive ground-contour-data that is representative of contours of a field that the plough is to work;
- and
- determine an actuator-control-signal for the actuator mechanism based on the ground-contour-data, wherein the actuator-control-signal is for setting the roll angle of the frame.
A computer-implemented method of operating a plough, the plough comprising:
- a frame;
- a ground engaging tool that is connected to the frame;
- and
- an actuator mechanism configured to control a roll angle of the frame, wherein the actuator mechanism comprises a turning actuator coupled to the frame and to a headstock of the plough, and the turning actuator is configured to rotate the frame about a longitudinal axis relative to the headstock to control the roll angle of the frame;
- wherein the method comprises:
- receiving ground-contour-data that is representative of contours of a field that the plough is to work;
- and
- determining an actuator-control-signal for the actuator mechanism based on the ground-contour-data, wherein the actuator-control-signal is for setting the roll angle of the frame.
A plough comprising:
- a frame;
- a ground engaging tool that is connected to the frame;
- an actuator mechanism configured to control a pitch angle of the frame, wherein the actuator mechanism comprises a depth-wheel-adjustable-linkage configured to control a height of a rear portion of the frame relative to a ground surface;
- and
- a controller configured to:
- receive ground-contour-data that is representative of contours of a field that the plough is to work;
- and
- determine an actuator-control-signal for the actuator mechanism based on the ground-contour-data, wherein the actuator-control-signal is for setting the pitch angle of the frame.
