Abstract

In one aspect, a system for monitoring the condition of a seedbed within a field may include a seedbed tool configured to ride along a seedbed floor as an implement frame is moved across the field. The system may also include an actuator configured to adjust the position of the seedbed tool along a lateral direction relative to the implement frame such that the seedbed tool traverses a lateral swath of the seedbed floor along the lateral direction. Furthermore, the system may include a seedbed floor sensor configured to detect the position of the seedbed tool relative to the implement frame. The position of the seedbed tool may be indicative of a profile of the lateral swath of the seedbed floor as the seedbed tool rides along the seedbed floor with movement of the implement frame in the forward travel direction.

First claim

The invention claimed is:

1. A system for monitoring the condition of a seedbed within a field, the system comprising:
an implement frame extending along a lateral direction between a first side and a second side;
a rotary disc configured to roll along a seedbed floor as the implement frame is moved across the field in a forward travel direction of the implement frame, the seedbed extending downwardly within the field from an outer seedbed surface to the seedbed floor;
an actuator configured to adjust a position of the rotary disc along the lateral direction relative to the implement frame as the implement frame is moved across the field in the forward direction of travel such that the rotary disc traverses a lateral swath of the seedbed floor along the lateral direction;
a seedbed floor sensor configured to detect a vertical position of the rotary disc relative to the implement frame; and
a controller communicatively coupled to the seedbed floor sensor, wherein the controller:
receives data from the seedbed floor sensor indicative of the vertical position of the rotary disc relative to the implement frame; and
determines a vertical profile of the lateral swath of the seedbed floor based on the received data as the rotary disc rolls along the seedbed floor with movement of the implement frame in the forward travel direction.

2. The system of claim 1 , wherein the controller is configured to control the operation of the actuator such that the rotary disc traverses the lateral swath of the seedbed floor along the lateral direction as the implement frame is moved across the field in the forward direction of travel.

3. The system of claim 1 , further comprising:
a location sensor configured to detect a parameter indicative of a location of the rotary disc within the field, the controller communicatively coupled to the location sensor, the controller is configured to generate a field map of the vertical profile of the lateral swath of the field being traversed by the rotary disc based on the determined vertical profile and the location sensor.

4. The system of claim 3 , further comprising:
a lateral position sensor configured to detect a parameter indicative of a lateral position of the rotary disc, the controller communicatively coupled to the lateral position sensor, the controller further configured to generate the field map of the vertical profile of the lateral swath of the field based on data from the lateral position sensor and the location sensor in addition to the determined vertical profile, the field map correlating the of the vertical profile of the seedbed to the lateral position of the rotary disc within of the lateral swath of the field.

5. The system of claim 1 , wherein the controller is configured to compare variations in the vertical profile of the lateral swath of the seedbed floor to a predetermined threshold.

6. The system of claim 5 , wherein, when the variations in the vertical profile of the lateral swath of the seedbed floor exceed the predetermined threshold, the controller is configured to initiate a control action to address the variations in the lateral swath of the vertical profile of the seedbed floor.

7. The system of claim 6 , wherein the control action comprises at least one of adjusting at least one of a ground speed of the implement frame, a down pressure applied through a ground-engaging tool supported on the implement frame, or a penetration depth of the ground-engaging tool.

8. The system of claim 7 , wherein the control action comprises providing a notification to an operator of a work vehicle pulling the implement frame across the field.

9. The system of claim 1 , further comprising:
a disc blade supported on the implement frame, the disc blade defining a width extending along the lateral direction between a forward edge of the disc blade and a rear edge of the disc blade, wherein a width of the lateral swath of the field along the lateral direction is equal to or greater than the width of the disc blade.

10. The system of claim 1 , wherein the actuator comprises a fluid-driven cylinder.

11. An agricultural implement, comprising:
a frame extending along a lateral direction between a first side and a second side;
a rotary disc configured to roll along a seedbed floor as the agricultural implement is moved across a field in a forward travel direction of the agricultural implement, the seedbed extending downwardly within the field from an outer seedbed surface to the seedbed floor;
an actuator configured to adjust a position of the rotary disc along the lateral direction relative to the frame as the agricultural implement is moved across the field in the forward direction of travel such that the rotary disc traverses a lateral swath of the seedbed floor along the lateral direction;
a seedbed floor sensor configured to detect a vertical position of the rotary disc relative to the frame; and
a controller communicatively coupled to the seedbed floor sensor, wherein the controller:
receives data from the seedbed floor sensor indicative of the vertical position of the rotary disc relative to the frame; and
determines a vertical profile of the lateral swath of the seedbed floor based on the received data as the rotary disc rolls along the seedbed floor with movement of the implement frame in the forward travel direction.

12. The agricultural implement of claim 11 , further comprising:
a disc blade supported on the frame, the disc blade defining a width extending along the lateral direction between a forward edge of the disc blade and a rear edge of the disc blade, wherein a width of the lateral swath of the field along the lateral direction is equal to or greater than the width of the disc blade.

13. The agricultural implement of claim 11 , wherein the actuator comprises a fluid-driven cylinder.

14. A method for monitoring the condition of a seedbed within a field being traversed by an agricultural implement, the agricultural implement including a frame and a rotary disc configured to roll along a seedbed floor as the agricultural implement is moved across the field in a forward travel direction, the method comprising:
controlling, with a computing device, an operation of an actuator such that the rotary disc traverses a lateral swath of the seedbed floor along a lateral direction of the agricultural implement as the agricultural implement is moved across the field in the forward direction of travel;
