Abstract

A farm implement for applying a product to a row crop or a row seeded field wherein the implement has a plurality of spaced-apart product dispensers mounted thereon, each of which is individually automatically controlled. The rate of product being dispensing from each of the product dispensers is automatically operated dependent upon the ground speed of the individual product dispensers or dependent on other criteria.

Claims

1. A farm implement for applying a product to a row crop or row seeded field, comprising:

an elongated transversely extending frame means adapted to be moved through the row crop or row seeded field;

a plurality of spaced-apart product dispensing devices mounted on said frame means;

and a rate control mechanism connected to each of said product dispensing devices;

each of said rate control mechanisms adapted to permit the variable flow of product through the associated product dispensing device dependent upon the ground speed of the product dispensing device.

2. The farm implement of claim 1 wherein the rate control mechanisms are GPS controlled.

3. The farm implement of claim 2 wherein said GPS controlled rate control mechanisms are individually controlled by pre-programmed or computerized control means.

4. The farm implement of claim 1 wherein said product dispensing devices are spraying units.

5. The farm implement of claim 1 wherein said product dispensing devices are fertilizing units.

6. The farm implement of claim 1 wherein said product dispensing devices are planting units.

7. The farm implement of claim 1 wherein said product dispensing devices are seeding units.

8. The farm implement of claim 1 wherein said product dispensing devices are chemical applicators.

9. The farm implement of claim 1 wherein a mechanically operated control mechanism is associated with the farm implement;

said control mechanism individually operating each of said product dispensing devices.

10. The farm implement of claim 9 wherein said mechanically operated control mechanisms operate individually in response to pre-programmed or computerized GPS control means.

11. The farm implement of claim 1 wherein an electrically operated control mechanism is associated with the farm implement;

said control mechanism individually controlling each of said product dispensing devices.

12. The farm implement of claim 11 wherein said electrically operated control mechanisms operate in response to a pre-programmed or computerized GPS control means.

13. The farm implement of claim 1 wherein an electronically operated control mechanism is associated with the farm implement;

said control mechanism individually controlling each of said product dispensing devices.

14. The farm implement of claim 13 wherein said electronically operated control mechanisms operate in response to a pre-programmed or computerized GPS control means.

15. The farm implement of claim 1 wherein a hydraulically operated control mechanism is associated with the farm implement;

said control mechanism individually controlling each of said product dispensing devices.

16. The farm implement of claim 15 wherein said hydraulically operated control mechanisms operate in response to a pre-programmed and computerized GPS control means.

17. The farm implement of claim 1 wherein each of said rate control mechanisms is individually and variably adjustable.
