Sectional control method for use with an agricultural implement
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.
1. A sectional control method for use with an agricultural implement having a toolbar with a plurality of soil engaging tools mounted thereto, the soil engaging tools being movable between a raised position and a lowered position and being 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, comprising:
moving the soil engaging tools to the lowered position;
mapping movement of the agricultural implement with a satellite navigation system when the soil engaging tools are in the lowered position to generate a seeded soil map;
comparing a real-time position of the agricultural implement during seeding of the soil to the seeded soil map with a processing unit, the processing unit activating an alert detectable by a user of the agricultural implement if the real-time position of the agricultural implement indicates that the agricultural implement is traversing over soil that has been previously seeded without automatically adjusting the seeding of the soil that has been previously seeded;
identifying to an operator of the agricultural implement one or more sections of the toolbar to be moved from the lowered position to the raised position so that the previously seeded soil is not disturbed;
manually initiating a corrective action to selectively raise the one or more sections of the toolbar identified from the lowered position wherein the soil engaging tools engage the soil to the raised position wherein at least a portion of the soil engaging tools are disengaged from the soil in response to the alert so that the previously seeded soil is not disturbed; and
terminating the alert, in response to the movement of the one or more sections of the toolbar to the raised position.
2. The sectional control method of claim 1 wherein activating an alert includes sounding an alarm in an operator cab of the agricultural implement.
3. The sectional control method of claim 2 wherein activating an alert includes illuminating one or more lamps in an operator cab of the agricultural implement.
4. The sectional control method of claim 1 wherein the step of identifying includes determining which, if any, portions of the agricultural implement are traversing the previously seeded soil, and illuminating a lamp corresponding to a respective portion of the agricultural implement if that respective portion of the agricultural implement is traversing the previously seeded soil.
5. The sectional control method of claim 1 further comprising maintaining activation of the alert until the operator of the agricultural implement manually initiates a corrective action to move the one or more sections of the toolbar to a raised position.
