Abstract

A method, a controller and a vehicle for performing agricultural operations on a field with parallel arranged rows having ends. The operations are performed at positions related to the positions of the rows under control of the controller, based upon stored information about the orientation of the rows, stored information about a distance between adjacent rows, a distance signal related to a distance traveled by the vehicle and a direction signal related to the heading of the vehicle. The invention is particularly suited for providing dams to prevent water from a head ditch to enter into pre-selected, dry furrows on a field with an irrigation arrangement with raised rows and lower furrows between the rows, or dams matching up with adjacent raised rows so that water runs down each furrow.

Claims

1. A method of performing agricultural operations on a field with parallel arranged rows having ends, comprising the following steps:

propelling a vehicle past the ends of the rows;

generating a position of the implement and deriving a heading of the implement by a location signal generation arrangement;

performing agricultural operations related to formation of dams for surface water management with an implement connected to the vehicle at desired positions related to the positions of the rows under control of a controller;

the controller controlling the implement to perform the operations based upon stored information about the orientation of the rows, stored information about a distance between adjacent rows, a distance signal related to a distance traveled by the vehicle and a direction signal related to the heading of the vehicle, and the desired position and angle of each of the dams with respect to a head ditch; and

instructing, by the controller, an actuator of the implement to build the dam or deposit material for the dam at the desired position compensating for orientation of the rows with respect to the heading of the vehicle such that the required distance between adjacent ones of the dams is proportional to I/cosine α

, where α

is the angle between the heading of the vehicle and the longitudinal direction of the rows.

2. The method according to claim 1, wherein the controller is controlling the operations based upon a calculated angle between the rows and the heading of the implement, the controller deriving the angle from the stored information about the orientation of the rows and from the direction signal related to the heading of the vehicle.

3. The method according to claim 1, wherein at least one of the distance signal and the direction signal is provided by a location signal generation arrangement generating location data of the position of at least one of the vehicle and the implement.

4. The method according to claim 3, wherein the location signal generation arrangement is mounted to one of the vehicle and the implement.

5. The method according to claim 1, wherein an operator inputs at least one of information about the orientation of the rows, information about the distance between adjacent rows, information about a desired distance between adjacent operations, information about an offset between the positions of the location signal generation arrangement and the implement, information about a desired location of a first operation, and information about the dimensions of the implement, via an operator interface into a memory connected to the controller, the controller using the information stored in the memory when controlling the implement.

6. The method according to claim 1, wherein on the field an irrigation arrangement with raised rows, lower furrows between the rows, and a transverse head ditch in the vicinity of the ends of the furrows is provided, and

the implement is depositing ground material at the desired positions in order to provide at least one of dams between the head ditch to prevent water from the head ditch to enter into pre-selected, dry furrows or dams matching up with adjacent raised rows so that water runs down each furrow.

7. The method according to claim 6, wherein the implement is scraping ground material together when the vehicle is moving, and the controller is controlling the implement to release the ground material at the desired position to build a dam.

8. A controller for controlling agricultural operations on a field with parallel arranged rows having ends, wherein:

the controller is connected to a location signal generation arrangement to receive a position of the implement and derive a heading of the implement;

the controller is provided on a vehicle to which an implement for performing agricultural operations, related to formation of dams for surface water management, is connected;

the controller operable to control the agricultural operations of the implement at desired positions related to the locations of the rows, when the vehicle is propelling past the ends of the rows, based upon at least one of stored information about an orientation of the rows, stored information about a distance between adjacent rows, a distance signal related to a distance traveled by the vehicle, a direction signal related to a heading of the vehicle, and the desired position and angle of each of the dams with respect to a head ditch, and

the controller arranged to instruct an actuator of the implement to build the dam or deposit material for the dam at the desired position;

compensating for orientation of the rows with respect to the heading of the vehicle such that the required distance between adjacent ones of the dams is proportional to I/cosine α

, where α

is the angle between the heading of the vehicle and the longitudinal direction of the rows.

9. The controller according to claim 8, wherein the controller is operable to control operations based upon a calculated angle enclosed between the furrows and a heading of the implement, the controller deriving the angle from the stored information about the orientation of the rows and from the direction signal related to the heading of the vehicle.

10. The controller according to claim 8, wherein at least one of the distance signal and the direction signal is provided by a location signal generation arrangement generating location data of the position of at least one of the vehicle and the tool.

11. The controller according to claim 10, wherein the location signal generation arrangement is mounted to one of the vehicle and the implement.

12. The controller according to claim 8, wherein an operator interface is provided, allowing an operator to input at least one of the information about the orientation of the rows, the information about the distance between adjacent rows, information about a desired distance between adjacent operations, information about an offset between the positions of the location signal generation arrangement and the implement, information about a desired location of a first operation, information about dimensions of the implement, and fine adjustment data for positions at which the operations are performed into a memory connected to the controller, the controller operable to use the information stored in the memory when controlling the implement.

13. A vehicle for performing agricultural operations on a field with parallel arranged rows having ends, wherein:

an implement for performing agricultural operations, related to formation of dams for surface water management, is connected to the vehicle;

a location signal generation arrangement for generating a position of the implement and deriving a heading of the implement;

a controller for controlling the implement to perform the operations is provided on the vehicle;
