Abstract

A planting apparatus includes a chassis and a row unit carried by the chassis. The row unit includes a unit body carried by the chassis; a metering device carried by the unit body; at least one furrowing disc carried by the unit body; at least one pressing wheel carried by the unit body behind the furrowing disc in a direction of travel; a travel arm carried by and pivotally movable relative to the unit body that defines a travel path; at least one closing disc positioned behind the at least one furrowing disc and in front of the at least one pressing wheel in the direction of travel and pivotally movable along the travel path by the travel arm; and a stop placed in the travel path of the travel arm that is configured to limit a vertical travel of the at least one closing disc.

Claims

1. An agricultural planting apparatus, comprising:

a chassis;

a row unit carried by said chassis, said row unit including;

a unit body carried by said chassis;

a metering device carried by said unit body;

at least one furrowing disc carried by said unit body;

at least one pressing wheel carried by said unit body behind said furrowing disc in a direction of travel;

a travel arm carried by said unit body, pivotally movable relative to said unit body and defining a travel path;

at least one closing disc positioned behind said at least one furrowing disc and in front of said at least one pressing wheel in the direction of travel and pivotally movable along the travel path by said travel arm; and

a stop placed in the travel path of said travel arm and configured to limit a vertical travel of said at least one closing disc.

2. The planting apparatus according to claim 1, wherein said stop is adjustably placed in the travel path of said travel arm.

3. The planting apparatus according to claim 1, further comprising a pair of surfaces carried by said unit body and defining a space therebetween, said travel arm being held in said space.

4. The planting apparatus according to claim 3, wherein said stop is mounted to at least one of said pair of surfaces.

5. The planting apparatus according to claim 3, wherein at least one of said pair of surfaces has at least two stop openings formed therein, said at least two stop openings being sized to hold said stop therein.

6. The planting apparatus according to claim 5, wherein one of said at least two stop openings has a first vertical position and another of said at least two stop openings has a second vertical position different than said first vertical position.

7. The planting apparatus according to claim 5, wherein said stop is held in one of said at least two stop openings.

8. The planting apparatus according to claim 5, wherein said pair of surfaces each has at least two stop openings formed therein, said at least two stop openings of each pair of surfaces being sized to hold said stop therein.

9. The planting apparatus according to claim 8, wherein said at least two stop openings of one of said pair of surfaces are aligned with corresponding stop openings on the other of said pair of surfaces.

10. The planting apparatus according to claim 9, wherein said stop is held within two of said aligned stop openings.

11. The planting apparatus according to claim 3, further comprising a mounting body connected to said unit body, said pair of surfaces being a part of said mounting body.

12. The planting apparatus according to claim 11, wherein said mounting body includes at least two side plates defining said pair of surfaces.

13. The planting apparatus according to claim 1, wherein said stop is placed in a downward direction of the travel path of said travel arm.

14. The planting apparatus according to claim 10, wherein said stop includes a top surface and said travel arm includes a bottom surface, said top surface of said stop contacting said bottom surface of said travel arm to limit the vertical travel of said at least one closing disc.

15. A closing assembly for an agricultural row unit, comprising:

a mounting body;

a travel arm pivotally connected to said mounting body and defining a travel path;

at least one closing disc pivotally connected to said mounting body by said travel arm and movable along the travel path of said travel arm; and

a stop placed in the travel path and configured to limit a vertical travel of said at least one closing disc.

16. The closing assembly according to claim 15, wherein said mounting body includes a pair of side plates defining a space therebetween, said travel arm being held in said space.

17. The closing assembly according to claim 16, wherein said stop is held in said space.

18. The closing assembly according to claim 16, wherein each of said side plates includes at least one stop opening formed therethrough that is sized to hold said stop therein.

19. The closing assembly according to claim 15, wherein said stop is adjustably placed in the travel path of said travel arm.

20. The closing assembly according to claim 15, wherein said stop includes a top surface and said travel arm includes a bottom surface, said top surface of said stop contacting said bottom surface of said travel arm to limit the vertical travel of said at least one closing disc.
