20080236461 | Wear Resistant Seed Tube for an Agricultural Planter - A seed tube for an agricultural planter having a rearwardly curving forward wall, a rearwardly curving rearward wall and opposing sidewalls defining a seed passageway which curves rearwardly from an upper ingress end toward a lower egress end. Wear resistant material is disposed proximate the egress end which provides a point of first contact with the opener disks thereby preventing appreciable wear of the egress end of the seed tube. | 10-02-2008 |
20080236462 | Seed Singulator - A seed singulator for use with a vacuum disk having a seed face and a shoulder. The seed singulator has a first member and a second member supported by biasing members. The first member has upper lobes disposed at a radius of curvature slightly less than the outside radius of a row of apertures on a seed plane of the vacuum disk. The seed member has lower lobes disposed at a radius of curvature slightly greater than the inside radius than the row of apradius. The biasing members permit the lobes to move with the seed plane and the shoulder as the vacuum disk rotates thereby maintaining their position with respect to the apertures. | 10-02-2008 |

20100180695 | LOAD SENSING PIN - A load sensing pin disposed to receive a load applied in a direction substantially transverse to a longitudinal axis of the pin. A load sensor is substantially fixedly oriented with respect to the applied load or alternatively with respect to the pin which is rotationally restrained with respect to a support structure. The load sensor is disposed to generate a load signal corresponding to strain of the pin resulting from the applied load. | 07-22-2010 |
20100198529 | SYSTEM AND METHOD FOR DETERMINING PROPER DOWNFORCE FOR A PLANTER ROW UNIT - A system and method for determining the appropriate downforce on an agricultural planter row unit that minimizes soil compaction while maintaining desired furrow depth. A load sensor is disposed to generate a load signal corresponding to loading on a depth regulation member of the row unit. In one method a load margin is calculated based on a minimum detected load value. In another method, a load margin is derived through a statistical analysis of the detected load values. The load margin calculated or derived by any of the methods is indicative of the amount of supplemental down force that should be increased or decreased to bring the load margin toward zero. A ground contact parameter may also be used in connection with the load margin to provide further confidence on the proper amount of downforce required to ensure furrow depth while minimizing soil compaction. | 08-05-2010 |
