Abstract

A device for planting different varieties of seeds is provided with a seed hopper or carousel that is selectively placed in open communication with a plurality of seed metering devices. A selectively positionable gate member directs the seeds to specific seed metering devices. The seed metering devices are movable on the device to engage a first metering device with a ground engagement assembly and a second metering device with a discharge container. The seed metering devices operate in alternating seed-dispersing and clearing modes simultaneously to speed planting. A GPS system may be incorporated to track and accurately control the planting operation.

Claims

1. A device for planting a variety of seeds in the ground, comprising:

2. The device of claim 1 wherein said first seed metering device is positioned in a generally forward facing direction and said second metering device is positioned in a generally rearward facing direction.

3. The device of claim 1 further comprising a sled member operatively slidably secured to said frame; said first and second seed metering devices being coupled with said sled member.

4. The device of claim 3 wherein said sled member is selectively movable along a generally transverse axis of said frame so that said first and second seed metering devices can be selectively positioned along said transverse axis.

5. The device of claim 4 further comprising a hydraulic actuator for selectively moving said sled member along said transverse axis.

6. The device of claim 1 having a first supply tube and a second supply tube; said first supply tube operatively connecting said seed container to said first seed metering device and second supply tube operatively connecting said seed container to said second seed metering device.

7. The device of claim 6 further comprising a gate member intermediate said seed container and said first and second supply tubes; said gate member being selectively movable to place said seed container in open communication with said first supply tube or said second supply tube.

8. The device of claim 7 further comprising a hydraulic actuator for selectively moving said gate member.

9. The device of claim 7 wherein said seed container is a hopper.

10. The device of claim 7 wherein said seed container is a seed carousel having a plurality of individual seed cups that are selectively movable along a pathway; said gate member having at least one opening positioned-along said carousel pathway.

11. The device of claim 1 further comprising at least one seed discharge cup operatively coupled to said frame.

12. The device of claim 11 wherein said first and second seed metering devices are selectively movable along a generally transverse axis of said frame so that said first or second seed metering device is positioned in open communication with said at least one seed discharge cup when said first or second seed metering device is operated in said clearing mode.

13. The device of claim 1 further comprising GPS means for selectively determining the location of the device and tracking its movement.

14. The device of claim 13 wherein said GPS means is operatively coupled to said first and second seed metering devices to initiate and terminate the sliding movement of said first and second seed metering devices.

15. The device of claim 14 wherein said GPS means is operatively coupled to said first and second seed metering devices to initiate and terminate the planting and clearing modes of said first and second seed metering devices.

16. A device for planting a plurality of seed varieties within a field, comprising:

17. The device of claim 16 further comprising a GPS assembly for tracking and at least partially controlling the device.

18. The device of claim 16 wherein said plurality of seed metering devices are coupled to a sled that is selectively movable on said frame to position said plurality of seed metering devices with respect to said ground engagement means.

19. The device of claim 18 further comprising a power cylinder operatively coupled to said sled for selectively moving said sled with respect to said frame.

20. The device of claim 16 further comprising a gate means for selectively distributing the seed varietals among the plurality of seed metering devices.
