Abstract

Disclosed herein is an agriculture planter. The planter may include a planter frame, a seed hopper and a trailing arm assembly. The planter frame may include a hitch tongue extending forwardly from the planter frame. The planter frame supports the seed hopper. The a trailing arm assembly is vertically pivotally coupled to a rear portion of the planter frame, extends rearward from the planter frame and includes a trailing arm frame and a lever arm vertically pivotally coupled to the trailing arm frame by a pivot point. The lever arm includes a leading end, a trailing end, a middle portion, a furrow opener disc and a first furrow closer wheel. The disc is rotatably mounted to the lever arm near the leading end. The first wheel is rotatably mounted to the lever arm near the trailing end. The middle portion is pivotably coupled to the pivot point.

Claims (15)

1. An agriculture planter comprising:

a planter frame;

a trailing arm assembly vertically pivotally coupled to a trailing side of the planter frame;

a rotatable furrow opening disc operably coupled to the trailing arm assembly; and

a first rotatable furrow closing wheel operably coupled to the to trailing arm assembly, wherein displacement of the first wheel relative to the trailing arm assembly causes displacement of the disc relative to the trailing arm assembly.

2. The planter of claim 1 , wherein displacement of the first wheel relative to the trailing arm assembly in an upward direction causes displacement of the disc relative to the trailing arm assembly in a downward direction.

3. The planter of claim 2 , wherein the displacement of the first wheel relative to the trailing arm assembly is generally greater than the displacement of the disc relative to the trailing arm assembly.

4. The planter of claim 2 , wherein the displacement of the first wheel relative to the trailing arm assembly is not equal to, but is proportional to, the displacement of the disc relative to the trailing arm assembly.

5. The planter of claim 2 , wherein displacement of the first wheel relative to the trailing arm assembly in a clockwise direction causes displacement of the disc relative to the trailing arm assembly in a clockwise direction.

6. The planter of claim 1 , wherein the trailing arm assembly further includes a second rotatable furrow-closing wheel.

7. The planter of claim 6 , wherein the second wheel is on an opposite side of the trailing arm assembly from the first wheel.

8. The planter of claim 1 , further comprising a lever arm pivotably coupled to the trailing arm assembly and operably coupling the disc and first wheel to each other.

9. The agricultural planter of claim 8 , wherein at least one end of the lever arm includes a plurality of mounting positions.

10. The planter of claim 1 , further comprising a fertilizer distribution tube operably coupled to the disc.

11. The agricultural planter of claim 1 further comprising a lever arm including at least a leading end, a middle portion and a trailing end, wherein a plurality of mounting positions are located on the leading end of the lever arm.
