Abstract

An agricultural implement is provided that includes a ground engaging tool configured to engage soil in a working position and to disengage the soil in a non-working position. The agricultural implement also includes an actuating cylinder coupled to the ground engaging tool and configured to transition the ground engaging tool between the working position and the non-working position based on a flow of fluid from a fluid supply system. In addition, the agricultural implement includes at least one sensor configured to output a signal indicative of a fluid pressure within the fluid supply system, and a controller configured to determine whether the ground engaging tool is in the working position or the non-working position based on the first signal.

First claim

The invention claimed is:

1. A method of operating an agricultural implement system, comprising:
providing a ground engaging tool configured to engage soil in a working position and to disengage the soil in a non-working position;
providing an actuating cylinder coupled to the ground engaging tool, wherein the actuating cylinder is configured to transition the ground engaging tool between the working position and the non-working position based on a flow of fluid from a fluid supply system;
receiving, at a controller of the agricultural implement system, a first signal from a first sensor, wherein the first signal is indicative of a first fluid pressure within the fluid supply system; and
determining, using the controller, whether the ground engaging tool is in the working position or the non-working position based only on the first signal.

2. The method of claim 1 , comprising controlling, using the controller, the flow of fluid provided by the fluid supply system to the actuating cylinder coupled to the ground engaging tool to transition the ground engaging tool between the working position and the non-working position.

3. The method of claim 2 , comprising increasing fluid pressure supplied to a first side of the actuating cylinder to induce the ground engaging tool to transition to the working position.

4. The method of claim 3 , comprising increasing fluid pressure supplied to a second side of the actuating cylinder to induce the ground engaging tool to transition to the non-working position.

5. The method of claim 1 , comprising outputting, from the controller, a second signal indicative of whether the ground engaging tool is in the working position or the non-working position based on the first signal from the first sensor.

6. The method of claim 1 , comprising comparing, using the controller, the first fluid pressure to one or more threshold values to determine whether the ground engaging tool is in the working position or the non-working position.

7. The method of claim 1 , comprising:
initiating an agricultural product flow while the ground engaging tool is in the working position; and
terminating the agricultural product flow while the ground engaging tool is in the non-working position.

8. A method of operating an agricultural implement system, comprising:
receiving, at a controller of the agricultural implement system, a first signal from a first sensor, wherein the first signal is indicative of a first fluid pressure within a fluid supply system;
receiving, at the controller, a second signal from a second sensor, wherein the second signal is indicative of a second fluid pressure within the fluid supply system, the first fluid pressure corresponds to a fluid pressure within a first side of an actuating cylinder, and the second fluid pressure corresponds to a fluid pressure within a second side of the actuating cylinder;
controlling, using the controller, a flow of fluid provided by the fluid supply system to the actuating cylinder coupled to a ground engaging tool to transition the ground engaging tool between a working position and a non-working position;
comparing, using the controller, the first fluid pressure, the second fluid pressure, or a combination thereof, to one or more threshold values; and
determining, using the controller, whether the ground engaging tool is in the working position or the non-working position based at least in part on the comparison.

9. The method of claim 8 , wherein the determination is delayed until the first fluid pressure, the second fluid pressure, or a combination thereof is outside of the one or more threshold values for a threshold duration.

10. The method of claim 8 , receiving, at the controller, a third signal indicative of a product delivery mode of operation, wherein the third signal instructs the controller to facilitate an automatic control of an agricultural product flow, a manual control of the agricultural product flow, or a combination thereof.

11. The method of claim 10 , wherein the automatic control of the agricultural product flow comprises:
initiating an agricultural product flow while the ground engaging tool is in the working position; and
terminating the agricultural product flow while the ground engaging tool is in the non-working position.
