Abstract

In one embodiment, an agricultural implement system includes a row unit, the row unit configured to dispose seed into a ground trench, and closing system corresponding to the row unit, the closing system configured to close the ground trench after disposition of the seed. The agricultural implement system further includes a double acting cylinder mechanically coupled to the closing system, the double acting cylinder comprising a cylinder side port and a rod side port and a fluid source fluidly coupled to the cylinder side port and configured to provide a cylinder side fluid. The agricultural implement system additionally includes a filter fluidly coupled to the rod side port. Filtered fluid enters the double acting cylinder via the rod side port.

First claim

The invention claimed is:

1. An agricultural implement system, comprising:
a pneumatic system comprising:
a fluid source configured to provide a cylinder side fluid to a cylinder side port of a double acting cylinder and a rod side fluid to a rod side port of the double acting cylinder; and
an inlet filter coupled to the rod side port and configured to filter the rod side fluid entering the double acting cylinder via the rod side port; and

a row unit having the double acting cylinder, wherein the row unit is configured to dispose seed into a ground trench.

2. The agricultural implement system of claim 1 , wherein the row unit comprises a closing system configured to close a ground trench, and wherein the double acting cylinder is mechanically coupled to the row unit to provide pneumatic power to the closing system.

3. The agricultural implement system of claim 2 , comprising a controller operatively coupled to the pneumatic system and configured to control the pneumatic system to actuate the double acting cylinder during operations of the closing system.

4. The agricultural implement system of claim 3 , wherein the controller is communicatively coupled to one or more pressure sensors, flow sensors, or combination thereof, disposed in the pneumatic system, and wherein the controller is configured to control the pneumatic system based on signals received from the sensors.

5. The agricultural implement system of claim 1 , wherein the pneumatic system comprises a manifold, a tee fitting, or combination thereof, wherein the inlet filter is disposed directly upstream of the manifold, the tee fitting, or the combination thereof, and wherein the manifold, the tee fitting, or the combination thereof, are disposed directly upstream of the rod side port.

6. An agricultural implement system, comprising:
a double acting cylinder, wherein the double acting cylinder is configured to provide pneumatic power for agricultural operations; and
a pneumatic system comprising:
a fluid source configured to provide a cylinder side fluid to a cylinder side port of the double acting cylinder and a rod side fluid to a rod side port of the double acting cylinder; and
an inlet filter coupled to the rod side port and configured to filter the rod side fluid entering the double acting cylinder via the rod side port.

7. The agricultural implement system of claim 6 , comprising a closing system configured to close a ground trench, wherein the double acting cylinder is mechanically coupled to the closing system.

8. The agricultural implement system of claim 6 , comprising a plurality of row units configured to dispose seed into a ground trench.

9. The agricultural implement system of claim 6 , wherein the inlet filter is disposed directly upstream of the rod side port.

10. The agricultural implement system of claim 6 , wherein the pneumatic system comprises a manifold, a tee fitting, or combination thereof, wherein the filter is disposed directly upstream of the manifold, the tee fitting, or the combination thereof, and wherein the manifold, the tee fitting, or the combination thereof, are disposed directly upstream of the rod side port.
