Abstract

An agricultural seeding machine movable in a planting direction includes a frame; a disc opener assembly carried by the frame and having a first axis of rotation; a gauge wheel assembly carried by the frame and having a second axis of rotation, and a press wheel assembly carried by the frame and having a third axis of rotation. The second axis is positioned forward of the first axis relative to the planting direction. The gauge wheel assembly overlaps the disc opener assembly relative to the planting direction. The third axis is positioned rearward of the first axis relative to the planting direction. The press wheel assembly overlaps the disc opener assembly relative to the planting direction.

Claims

1. An agricultural seeding machine movable in a planting direction, comprising:

a frame;

a disc opener assembly carried by said frame and having a first axis of rotation and having an outer side away from said frame;

a gauge wheel assembly carried by said frame and having a second axis of rotation, said second axis positioned forward of said first axis relative to said planting direction, said gauge wheel assembly overlapping said disc opener assembly relative to said planting direction; and

a press wheel assembly carried by said frame and having a third axis of rotation, said third axis positioned rearward of said first axis relative to said planting direction, said press wheel assembly overlapping said disc opener assembly relative to said planting direction, said press wheel assembly being on the form of a pair of wheels positioned adjacent the outer sides of said disc opener assembly.

2. The agricultural seeding machine of claim 1, wherein said disc opener assembly includes a bearing housing, said gauge wheel assembly overlapping said bearing housing relative to said planting direction.

3. The agricultural seeding machine of claim 1, wherein said gauge wheel assembly defines a gauge wheel contact patch with soil, said gauge wheel contact patch positioned forward of said first axis of rotation relative to said planting direction.

4. The agricultural seeding machine of claim 1, wherein said gauge wheel assembly is vertically adjustably coupled with said frame.

5. The agricultural seeding machine of claim 1, wherein said press wheel assembly defines a press wheel contact patch with soil, and said disc opener assembly defines a contact line with the soil, said press wheel contact patch positioned rearward of said disc opener contact line relative to said planting direction.

6. The agricultural seeding machine of claim 1, wherein said press wheel assembly is vertically movably coupled with said frame, and includes an adjustable down force pressure system.

7. The agricultural seeding machine of claim 6, wherein said down force pressure system includes one of a pivot mechanism, and a parallel linkage.

8. The agricultural seeding machine of claim 1, wherein said gauge wheel assembly includes a pair of gauge wheels.

9. The agricultural seeding machine of claim 1, wherein said disc opener assembly includes a pair of disc blades.

10. The agricultural seeding machine of claim 1, wherein said press wheel assembly includes a pair of press wheels.

11. A furrow opener/closer for an agricultural seeding machine movable in a planting direction, comprising:

a disc opener blade having a first axis of rotation and an outer facing side;

a gauge wheel having a second axis of rotation, said second axis positioned forward of said first axis in said planting direction, said gauge wheel overlapping said disc opener blade in said planting direction; and

a press wheel having a third axis of rotation, said third axis positioned rearward of said first axis in said planting direction, said press wheel overlapping said disc opener blade in said planting direction, said press wheel being positioned adjacent the outer facing side of said disc opener blade.

12. The furrow opener/closer of claim 11, wherein said disc opener blade includes a bearing housing, said gauge wheel overlapping said bearing housing relative to said planting direction.

13. The furrow opener/closer of claim 11, wherein said gauge wheel defines a gauge wheel contact patch with soil, said gauge wheel contact patch positioned forward of said first axis of rotation relative to said planting direction.

14. The furrow opener/closer of claim 11, wherein said press wheel defines a press wheel contact patch with soil, and said disc opener blade defines a contact line with the soil, said press wheel contact patch positioned rearward of said disc opener contact line relative to said planting direction.

15. A method of planting with an agricultural seeding machine moving in a planting direction, comprising the steps of:

firming soil with a gauge wheel assembly;

opening a seed trench in the firmed soil with a disc opener assembly, said disc opener assembly overlapping said gauge wheel assembly in the planting direction;

depositing a seed in the opened seed trench; and

closing the seed trench with a press wheel assembly, said press wheel assembly overlapping said disc opener assembly in the planting direction and being positioned adjacent the outer facing side of said disc opener assembly.
