Abstract

In some implementations, an agricultural row unit assembly can include a pair of tine assemblies each having at least one tine mounted to a hub, said hub adapted to rotate about a first axis, where rotation of said pair of tine assemblies fractures soil and forms a pair of outer edges of a tilled row with a row width. In some embodiments, the device can include a rolling cultivator adapted to form a generally flat profile to said tilled row. In some embodiments, the device can include a seedbed cultivator adapted to work through said soil in the area defined by the row width. In some embodiments, the device can include a pair of gauge wheels fastened to each end of the shaft such that said gauge wheels are located outside said pair of outer edges of a tilled row.

First claim

What is claimed is:

1. A row unit assembly for tilling a row of soil for planting seeds, the row unit assembly comprising:
a pair of tine assemblies each having at least one tine mounted to a hub, said hub adapted to rotate about a first axis, whereby rotation of said pair of tine assemblies fractures soil and forms the outer edges of a tilled row with a row width;
a rolling cultivator adapted to treat soil being ripped and fractured and form a generally flat profile to said tilled row; and
a seedbed cultivator adapted to work through said soil in the area defined by said row width,
wherein said rolling cultivator rotates about a shaft,
wherein said rolling cultivator is set at a depth corresponding to the planting of seed, and
wherein a pair of gauge wheels are fastened to each end of said shaft such that said gauge wheels are located outside the outer edges of said tilled row.

2. The row unit assembly of claim 1 , wherein said row width is in the range of 6″ to 12″.

3. The row unit assembly of claim 1 , wherein each of said pair of tine assemblies has a predetermined depth in the soil of less than or equal to 6″.

4. The row unit assembly of claim 1 , wherein said at least one tine has an outer diameter of rotation and defines a horizontal plane parallel to said first axis, and said outer diameter is positioned in the range of 0 degrees to 5 degrees from said horizontal plane.

5. The row unit assembly of claim 1 , wherein said at least one tine is a pair of tines and spacing between the pair of tines is in the range of 6″ to 12″.

6. The row unit assembly of claim 1 , wherein said at least one tine is configured with six tines.

7. The row unit assembly of claim 1 , wherein said rolling cultivator is position centrally with a center axis, said rolling cultivator forming a pair of spider configurations about the center axis.

8. The row unit assembly of claim 7 , wherein said pair of spider configurations works the soil towards the center axis of the tilled row.

9. The row unit assembly of claim 1 , wherein said rolling cultivator has a width in the range of 10″ to 11″.

10. The row unit assembly of claim 1 , wherein said rolling cultivator and said first axis have a predetermined length in the range of 39″ to 42″.

11. The row unit assembly of claim 1 , further comprising a pre-fracture coulter positioned along a center axis and forward of said rolling cultivator.

12. The row unit assembly of claim 1 , wherein said seedbed cultivator is a shank.

13. The row unit assembly of claim 1 , wherein said seedbed cultivator is a disk.
