Fertilizer closing tandem

1. An agricultural vehicle, comprising:

a chassis;

a storage tank carried by the chassis; and

a row unit carried by the chassis, the row unit including:

a row body;

an opening blade carried by the row body and configured to open a trench as the row body is carried in a direction of travel;

a pivot arm comprising a first end and a second end, wherein the first end is connected to the row body and the pivot arm extends from the row body toward the second end in a direction substantially opposite to the direction of travel;

a closing tandem carried by the row body behind the opening blade and pivotally movable relative to the row body, the closing tandem including

a pivot plate connected to the second end of the pivot arm, wherein the pivot plate and the pivot arm are positioned at different angles relative to the direction of travel;

a closing tandem arm connected to the pivot plate via a first bushing positioned between the pivot plate and a surface of the closing tandem arm and configured to provide a spaced-apart orientation between the pivot plate and the surface of the closing tandem arm, the closing tandem arm including a closing arm at one end and a press arm at an opposite end;

a closing disc rotatably connected to the closing arm; and

a press wheel rotatably connected to the press arm,

wherein the closing tandem arm is longitudinally aligned along a longitudinal axis which extends through the closing arm and the press arm.

2. The agricultural vehicle according to claim 1 , wherein the closing disc is horizontally tilted in a first horizontal direction and the press wheel is horizontally tilted in a second horizontal direction that is opposite to the first horizontal direction.

3. The agricultural vehicle according to claim 1 , wherein the press wheel defines a camber angle between 0 and 12 degrees.

4. The agricultural vehicle according to claim 3 , wherein the camber angle is between 5 and 7.5 degrees.

5. The agricultural vehicle according to claim 1 , wherein the press wheel rotates about a rotation rod that is held perpendicular to the direction of travel.

6. The agricultural vehicle according to claim 1 , wherein the press wheel includes a crown ridge projection which extends outwardly about a circumference of the press wheel and a plurality of spaced-apart side projections which extend laterally away from the crown ridge projection.

7. The agricultural vehicle according to claim 1 , wherein a second bushing is positioned opposite to the first bushing on an opposite surface of the closing tandem arm.

8. The agricultural vehicle according to claim 1 , wherein the closing arm defines a closing arm length and the press arm defines a press arm length that is less than the closing arm length.

9. The agricultural vehicle according to claim 1 , wherein the closing tandem arm pivots about a pivoting member, and a rotational center of the closing disc is positioned farther from the pivoting member than a rotational center of the press wheel.

10. The agricultural vehicle according to claim 9 , wherein the closing disc has a closing disc weight and the press wheel has a press wheel weight that is less than the closing disc weight.

11. An agricultural vehicle, comprising:

a chassis;

a storage tank carried by the chassis; and

a row unit carried by the chassis, the row unit including:

a row body;

a pivot arm comprising a first end and a second end, wherein the first end is connected to the row body and the pivot arm extends from the row body toward the second end in a direction substantially opposite to the direction of travel;

an opening blade carried by the row body and configured to open a trench as the row body is carried in a direction of travel; and

a closing tandem carried by the row body behind the opening blade and pivotally movable relative to the row body about the pivot point, the closing tandem including

a pivot plate connected to the second end of the pivot arm, wherein the pivot plate and the pivot arm are positioned at different angles relative to the direction of travel;

a closing tandem arm connected to the pivot plate via a first bushing positioned between the pivot plate and a surface of the closing tandem arm and configured to provide a spaced-apart orientation between the pivot plate and the closing tandem arm, the closing tandem arm including a closing arm at one end and a press arm at an opposite end;

a closing disc rotatably connected to the closing arm; and

a press wheel rotatably connected to the press arm,

wherein the closing tandem arm is longitudinally aligned along a longitudinal axis which extends through the closing arm and the press arm.

12. The agricultural vehicle according to claim 11 , wherein the closing disc is horizontally tilted in a first horizontal direction and the press wheel is horizontally tilted in a second horizontal direction that is opposite to the first horizontal direction.

13. The agricultural vehicle according to claim 11 , wherein the press wheel includes a crown ridge projection which extends outwardly about a circumference of the press wheel and a plurality of spaced-apart side projections which extend laterally away from the crown ridge projection.

14. The agricultural vehicle according to claim 11 , wherein a second bushing is positioned opposite to the first bushing on an opposite surface of the closing tandem arm.

15. The agricultural vehicle according to claim 11 , wherein the closing arm has a closing arm length and the press arm has a press arm length that is less than the closing arm length.
