Abstract

A sectional control apparatus and method prompts the operator of an implement when the implement, or portion thereof, is traversing over land that has already been seeded and/or disturbed. The apparatus includes a GPS or GNSS receiver that communicates with a GPS or GNSS system and a controller that maps movement of the implement so that real-time positional data for the implement can be compared to the movement map. When the position of the implement, or portion thereof, is detected as moving over previously seeded and/or disturbed land, the controller activates an alert mechanism in the operator cab of the implement to notify the operator that sectional control, i.e., shutting down metering of product or raising the tool bar, needs to be implemented.

Claims

1. An agricultural implement for depositing particulate matter into soil, comprising:

a drill having a plurality of soil engaging tools that are movable between a raised position and a lowered position, the soil engaging tools configured to be disengaged from the soil when in the raised position and configured to be engaged with the soil when in the lowered position;

a satellite navigation system that maps movement of the implement when the soil engaging tools are in the lowered position and provides an output signal when the implement traverses a region of the soil that has been seeded;

an alert that is activated when the satellite navigation system provides the output signal, the alert configured to notify an operator that the implement is traversing a region of the soil that has previously been deposited with particulate matter without automatically adjusting the deposition of the particulate matter into the region of the soil that has previously been deposited with particulate matter and to notify the operator of the implement that at least one of the plurality of soil engaging tools needs to be moved to the raised position; and

a controller that maintains activation of the alert until the operator has taken a corrective measure to disengage the soil engaging tools from engagement with the soil that has been seeded.

2. The apparatus of claim 1 wherein the alert includes a light that is illuminated when the satellite navigation system provides the output signal.

3. The apparatus of claim 1 wherein the alert is an alarm that is sounded when the satellite navigation system provides the output signal.

4. The apparatus of claim 1 wherein the alert is located within an operator cab of the implement.

5. The apparatus of claim 1 further comprising an air cart coupled to the drill and configured to supply particulate matter to the drill.

6. The apparatus of claim 1 wherein the satellite navigation system is a GPS navigation system.

7. The apparatus of claim 1 wherein the controller maintains activation of the alert until the operator has moved the soil engaging tools to the raised position.

8. An agricultural implement for injecting material into soil, wherein the material is seed, fertilizer, or seed and fertilizer, comprising:

a frame assembly including a central frame and a plurality of elongate mounting arms mounted to the central frame, each adapted to be moved from a raised position to a lowered position, and soil engagers mounted on each of the mounting anus and adapted to engage soil when each of the mounting arms is in the lowered position;

a lifting arrangement operatively connected to the frame assembly for raising and lowering the frame assembly between the raised position and the lowered position; and

an alert structure operatively connected to a satellite navigation system for alerting an operator of the implement that the satellite navigation system has determined that a portion of the frame assembly is traversing regions of soil which have been previously seeded, the alert structure notifying the operator that the implement is traversing a region of the soil that has previously been deposited with particulate matter without automatically adjusting the deposition of the particulate matter into the region of the soil that has previously been deposited with particulate matter and notifying the operator of the implement to manually activate the raising and lowering means to raise the frame assembly from the lowered position to the raised position.

9. The agricultural implement of claim 8 wherein the alert structure includes an audible alert that is sounded when the satellite navigation system has determined that a portion of the frame assembly is traversing regions of soil which have been previously seeded.

10. The agricultural implement of claim 8 wherein the alert structure includes one or more lights that are illuminated when the satellite navigation system has determined that a portion of the frame assembly is traversing regions of soil which have been previously seeded.

11. The agricultural implement of claim 8 wherein the alert structure is located within an operator cab of the implement.

12. The agricultural implement of claim 8 further comprising an air cart coupled to the frame assembly and configured to supply particulate matter to a material meter arrangement.
