Abstract

A method performing an agricultural task on a field, the method comprising: identifying a number of plants in the field on a per unit area; determining a field pattern of plant maintenance for the plants in the field, the field pattern comprising: a planting instruction for travel in a first direction; and a plant maintenance instruction for travel in a second direction which is not parallel to the first direction, the plant maintenance instruction generated using at least one parameter corresponding to the number of plants in the field on a per unit area.

First claim

The invention claimed is:

1. A method for performing an agricultural task on a field, the method comprising:
determining a planting instruction for travel in a first direction, the planting instruction to vary a first spacing between plants in a first row;
determining a plant maintenance instruction for travel in a second direction, which is not parallel to the first direction, the plant maintenance instruction generated using at least one parameter corresponding to a number of plants per unit area in the field; and
positioning a unit on an implement to carry out the plant maintenance instruction based on the first spacing and the at least one parameter.

2. The method of claim 1 , further including planting a seed in the field using the planting instruction with a planter in the first direction.

3. The method of claim 2 , further including performing a plant maintenance measure using the plant maintenance instruction with a plant maintenance machine in the second direction.

4. The method of claim 1 , further including performing a plant maintenance measure using the plant maintenance instruction with a plant maintenance machine in the first direction.

5. The method of claim 3 , wherein the at least one parameter of the plant maintenance instruction is generated using at least one of: the first spacing of the plants in the first direction, a second spacing of the plants in the second direction, an angle between the first direction and the second direction, and a planned void in a field pattern.

6. The method of claim 5 , wherein the number of plants per unit area upon which the plant maintenance measure will be performed is determined by a respective location on the field.

7. The method of claim 6 , wherein the at least one parameter continuously changes in at least one of the first direction and the second direction as a function of the respective location on the field.

8. The method of claim 7 , wherein a spacing between a first unit and a second unit of the implement of the plant maintenance machine is adjustable using at least one actuator.

9. The method of claim 7 , wherein a track width between wheels of the plant maintenance machine is adjustable using at least one actuator.

10. The method of claim 9 , further including adjusting the track width based on at least one of a first tramline of the first direction and a second tramline of the second direction, the first tramline based on a spacing between adjacent rows in the first direction and the second tramline based on the spacing between adjacent rows in the second direction.

11. The method of claim 10 , wherein a position of the second tramline is generated for the plant maintenance machine in advance of planting.

12. The method of claim 10 , wherein a position of the second tramline is generated for the plant maintenance machine during planting using a local sensor on the planter.

13. The method of claim 10 , wherein the track width of the second tramline of the plant maintenance machine is generated in advance of planting.

14. The method of claim 10 , wherein the width of the track width of the second tramline of the plant maintenance machine is generated during planting using a local sensor on the planter.

15. The method of claim 5 , wherein the plant maintenance instruction updates a location of the planned void in the field pattern based on an occurrence of an unintentional void, the unintentional void to occur during planting in a different location from the planned void.

16. An agricultural machine system for performing an agricultural task in a field, the agricultural machine system comprising:
an agricultural machine;
a frame connected to the agricultural machine, the frame configured with at least two units to perform an agricultural task;
a controller in communication with the agricultural machine and the at least two units, the controller configured to determine agricultural task instructions, the agricultural task instructions including:
a first agricultural task instruction for travel in a first direction, the first agricultural task instruction to vary a first spacing between plants in a first row; and
a second agricultural task instruction for travel in a second direction, which is not parallel to the first direction, the second agricultural task instruction for travel in the second direction is generated using at least one parameter corresponding to crop density; and

actuators in communication with the agricultural machine and the at least two units, the actuators configured to position the at least two units based on the first spacing and the at least one parameter.

17. The agricultural machine system of claim 16 , wherein the at least two units are configured to be in an adjustable relationship with each other.

18. The agricultural machine system of claim 16 , wherein the first agricultural task instruction is performed using a planter, the planter configured to plant seed using at least in part a planting instruction.

19. The agricultural machine system of claim 16 , wherein the second agricultural task instruction is performed using a cultivator, the cultivator configured to cultivate plants in the field using at least in part a plant maintenance instruction.

20. The agricultural machine system of claim 16 , wherein the first agricultural task instruction is performed using a cultivator, the cultivator configured to cultivate plants in the field performing a plant maintenance measure using at least in part a plant maintenance instruction.
