Patent number: 9814171Abstract: An agricultural implement has a closing disk assembly for closing furrows along a section of ground. The closing disk assembly has a pair of closing disks attached to opposite sides and opposite ends of a walking beam. The closing disks are offset from a reference plane of the closing disk assembly. The walking beam is rotatably coupled to the closing disk assembly through a rocker assembly, a support arm, and a mounting assembly. The walking beam may rotate relative to the rocker assembly to account for variations in the angle of the ground relative to the disks.Type: GrantFiled: August 14, 2014Date of Patent: November 14, 2017Assignee: DEERE & COMPANYInventors: Luc Janelle, Adam D.

Patent number: 7938074Abstract: A pressure sensing system for a seeding machine such as a planter to measure the down force on a planter row unit uses a wireless pressure sensor embedded in a load carrying wheel of the row unit. In a preferred embodiment, the pressure sensor is a passive piezoelectric pressure sensor that is a transmitter only, transmitting both pressure and RFID the information that identifies the particular sensor. Multiple sensors may be employed in each wheel and sensors may be employed in more than one wheel of the row unit, such as the gauge wheels on opposite sides of the trench opening disks. The sensors may be made of a PVDF, a known piezoelectric material. A wireless receiver is located on the planter frame or could be located elsewhere to receive the signals from the pressure sensor. A controller determines from the signal, any change in down force and commands the change to a down force generator on the row unit.Type: GrantFiled: January 22, 2009Date of Patent: May 10, 2011Assignee: Deere & CompanyInventor: James Z.

Patent number: 6314897Abstract: An improved furrow closing system and method are disclosed for agricultural seeders, particularly no-till seeders, that produce an open furrow in the soil into which seeds are placed. The closing system includes one or more spoked wheels rotatably mounted rearward of the seed furrow opener of the seeder. The vertical angle and lateral alignment at which the spoked wheel is mounted, together with the shape and length of the spokes themselves, provide a gentle closing of the furrow by slicing instead of squeezing or wedging, a shattering of the furrow sidewall and a pushing of the fragments into the furrow. The shattering of the furrow sidewall results in a more consistent furrow closure, a more rapid and uniform seed germination and seedling emergence, a higher percentage of emergence, and an improved seedling root growth. The spoked wheel has a plurality of spokes projecting radially from the hub of the wheel.Type: GrantFiled: November 2, 1999Date of Patent: November 13, 2001Inventor: Matthew P. Hagny

Patent number: 6216616Abstract: A coulter closing wheel assembly, a method of planting, and a mid row banding pneumatic coulter drill assembly support vehicle. One fertilizer coulter is positioned between two seeding coulters. The seeding coulters are followed by a furrow closing disc which scrubs the ground and pushes soil back into the furrow. The seeding coulters are also followed directly by a packer wheel. The fertilizer coulters may or may not employ a furrow closing disc, depending on the type of fertilizer and the type of soil. In the event of granular or liquid nitrogen fertilizers the closing disc is generally not necessary. However, when a gaseous fertilizer such as anhydrous ammonia is applied to the soil, the furrow closing disc is necessary in order to prevent the escape of the anhydrous ammonia into the atmosphere. The coulters are firmly attached to horizontal frame members of the drill and placed at an angle of a few degrees off the direction of travel.Type: GrantFiled: July 19, 1999Date of Patent: April 17, 2001Assignee: Bourgault Industries Ltd.Inventor: Gerard F.

Patent number: 6119608Abstract: The planer row unit has a unit frame with a front member that is adapted to be secured to a tool bar. A sub frame is secured to the front member by parallel links. A furrow opener disk, a seed shoe and a gauge wheel are secured to the subframe.A cam plate supported by a spring to the rear of the seed shoe presses seeds into moist soil in the bottom of a seed furrow. A seed covering disc is supported by a covering disc shank to the rear and to one side of the furrow opener. The covering disc has a circular plate portion that faces downwardly and forwardly, moves loose soil from the furrow opener into the seed furrow and rotates about a central axis that extends downwardly from a horizontal plane. A flange, with notches extends radially outward and rearwardly from the outer periphery of the circular plate portion, rolls and slides along the surface and limits soil penetration by the covering disk.Type: GrantFiled: July 14, 1998Date of Patent: September 19, 2000Assignee: Hiniker CompanyInventors: Richard L. Peterson, Roger J. Scheurer

Patent number: 6032593Abstract: A combination seed and fertilizer opener having separate placement includes a first angled flat disk with a gauge wheel arrangement providing an initial furrow for a first material such as fertilizer. A second opener disk, smaller than the first and concave rather than flat, includes an edge that projects forwardly along the trailing side of the first disk to a forwardmost edge location adjacent the hub of the first disk. The hub of the concave disk is very closely adjacent the trailing edge of the large disk. A tube and boot assembly terminates within the concavity of the second disk near the rear periphery of the first disk. The concave disk forms a seed furrow to receive seed or second material from the tube and boot assembly. The front of the concave disk runs in undisturbed soil but is sufficiently close to the fertilizer furrow to press and cover the fertilizer. The second disk concavity also prevents excessive soil throw.Type: GrantFiled: April 27, 1998Date of Patent: March 7, 2000Assignee: Deere & CompanyInventors: Ignatz Wendling, Lyle Eugene Stephens

Patent number: 5752454Abstract: A method and apparatus for improved agricultural seeding; especially useful in no-till direct seeding. In the illustrated embodiment an inclined furrow is cut with a rotating disk that is inclined with respect to the vertical and the horizontal; the furrow has a raised lip, and straw and the like stalks are cleaved during the cutting. Seed is inserted by known means, and then a packer wheel, preferentially inclined in vertical and horizontal directions opposite to those the disk is inclined, runs across the lip and closes the furrow. Advantages include substantially reduced energy required for the furrow cutting, less weight required on the furrowing disk, more even seeding depth, less hairpinning, less soil disturbance, and less weed seed burial.Type: GrantFiled: March 7, 1997Date of Patent: May 19, 1998Inventor: Hugh Barton

Patent number: 5375542Abstract: A seed covering apparatus for covering seeds with soil after an agricultural seed planter places the seeds within an open seed trench and before the planter closes the seed trench. The apparatus includes a disk with a center guide hole and a sealed bearing attached within the guide hole. An adjustable mounting assembly fixes the sealed bearing to the planter so that the disk can rotate about the bearing along one side of the seed trench. The mounting assembly orients the disk at an acute angle to the seed trench so that rotation of the disk along the side of the trench transfers soil from the side into the bottom of the seed trench. The transferred soil completely covers the seeds within the trench prior to closure of the trench by the planter.Type: GrantFiled: April 20, 1993Date of Patent: December 27, 1994Inventor: Paul E.
