The closing wheel frame has a pair of closing wheels attached at a rear end and a pair of mounting openings formed at a front end. The pivot assembly includes ball bearings having outer races fit loosely within each of the mounting openings of the closing wheel frame. The inner races of the ball bearings are secured to the planter frame using threaded nut and bolt assemblies. The closing wheel frame is pivotal relative to the planter frame during normal operation by relative movement between the inner and outer races of the bearing. Variations of the mounting openings in the closing wheel frame are disclosed, including a tubular part, heavy washer or other annular structure welded to an outside surface of the closing wheel frame, or a bearing housing formed integral with the closing wheel frame. | ||||||
| 54 | Seed flap for controlling seed placement | US10225422 | 2002-08-22 | US06666156B1 | 2003-12-23 | Dean Mayerle; Vince Colistro; Dick Friesen; Robin Schilling |
| A seed flap for a disc opener associates with an air seeder operable to place seed and fertilizer into a furrow formed in the ground by the disc opener. The seed flap is formed from a non-flexible material, such as an abrasion resistant steel, and pivotally mounted to the seed tube to permit the seed flap to trail behind the seed tube and control the placement of seeds and/or fertilizer discharged from the seed tube. The pivotal mounting of the seed flap will provide movement of the seed flap relative to the seed tube to permit the seed flap to more consistently align with the bottom of the furrow and better follow the furrow bottom created by the disc opener while the disc opener is moving through a turn. A spring mechanism operably coupled to the seed flap will provide a positive force for firming the placement of the seed into the soil. A retention device, such as a clip, will be operable to hold the seed flap in an elevated, inoperable position as desired by the operator. | ||||||
| 55 | Liquid distribution apparatus for distributing liquid into a seed furrow | US09832740 | 2001-04-09 | US06453832B1 | 2002-09-24 | Paul E. Schaffert |
| A liquid distribution apparatus for use with a planter, drill or other farming implement having a seed tube that deposits seeds in a furrow. The liquid distribution apparatus includes a supply channel in fluid connection with a hose supplying a liquid to the furrow. The liquid distribution apparatus also includes a distribution channel that is oriented to distribute the liquid onto one or both sidewalls of the furrow. The apparatus may be used alone or along with an extension for reducing seed bounce. | ||||||
| 56 | Extension for reducing seed bounce and associated hose attachment | US09563106 | 2000-05-02 | US06283050B1 | 2001-09-04 | Paul E. Schaffert |
| An extension for use with a furrow opener is disclosed for properly placing seeds in a furrow. The extension attaches by way of particular attachment brackets to the furrow opener to help direct bouncing seeds into the vertex in the bottom portion of the furrow. The extension comprises an elongated flexible body member defining a general arcuate shape, and also defines an upper segment and a lower segment. The upper segment defines an attachment structure for releasable engagement to the furrow opener. The lower segment depends downwardly and rearwardly from the furrow opener and extends into the furrow. The lower segment has a width dimension decreasing continuously along its length, the width dimension substantially equal to but less than the width of the furrow along the length of the extension. The lower segment terminates at a trailing end, which is spaced above the centrally located bottom portion of the furrow. | ||||||

| 58 | Method and tool for quick replacement of drill boots | US530668 | 1995-09-20 | US5601041A | 1997-02-11 | James Boyde |
| A scissor-type jack is used to separate the yoke that holds a drill boot. The jack or separator is expanded to bend the yoke outward thereby allowing the drill to disengage from the yoke. A replacement boot or the repaired boot is installed in the yoke and the separator contracted until the boot reengages the yoke. The separator expands and contracts responsive to the rotation of a hexagonal head that can be rotated by a conventional socket using a ratchet. | ||||||
| 59 | Furrow opener and follower blade | US597118 | 1984-04-05 | US4598654A | 1986-07-08 | Forrest E. Robertson; Donald E. Williams |
| A pair of circular, furrow-opening disks, supported by separate, angularly oriented axles, rotatable simultaneously as a unit and converging to a leading zone of interengagement within the ground for preventing soil buildup therebetween, have a wedge-shaped, trailing blade, rigidly supported therebetween immediately ahead of materials gravitating into the furrow, and following at a greater depth, for slicing the series of unplowed scallops at the bottom of the furrow, clearing the furrow bottom of loose soil and forming a truly V-shaped, ridgeless, material-receiving apex compressed into a smooth, firm sidewall formation. | ||||||
| 60 | Coulter attachment for seed planting apparatus | US278716 | 1981-06-29 | US4407371A | 1983-10-04 | Gregory D. Hohl |
| Apparatus is disclosed which facilitates the ready attachment and detachment of coulters to a standard seed planting device. The seed planting device is typically of a type that is towed behind a tractor and automatically furrows the ground, deposits the seeds in the furrows at spaced intervals and covers the seeds over. The disclosed apparatus allows an operator to readily attach a plurality of coulters to this planting device thereby enabling its use for minimum-till, or no-till farming operations. The coulters are attached to a framework which is bolted onto the planter frame. This framework may be readily removed as a unit to enable the use of the planter in its standard condition. The framework locates the coulters in a forwardmost direction to increase the downward force on same so as to enable no-till farming operations with hard or rocky soil. This location of the coulters eliminates the need for ballast weights. | ||||||
