20080282950 | Drill Disc Opener - The present planter unit, and planter implements using the present planter unit, include first and second discs and first and second pathways. The first and second discs may be generally planar and in a non-overlapping relation. As the planter unit is towed through a field, the first disc creates a first trench in the seedbed and the first pathway deposits a first material in the first trench. Subsequently, the second disc creates a second trench which is continuous with the first trench and partially fills the first trench. A second material is deposited in the second trench by the second pathway. | 11-20-2008 |

20130019787 | All terrian rotary planting device - This planting device has a rotary excavator head instead of a plow to make a furrow The excavator uses a various number of teeth to cut the soil and two flat plates and centrifugal force to distribute the soil evenly around the hole to be excavated for planting. The cutting action of the teeth breaks up the soil into a very fine media. The two flat plates use centrifugal force to distribute it evenly around the hole. | 01-24-2013 |

111158000 | Power rotated | 3 |
20100083886 | Seed row shaper attachment for a power tiller - An attachment for a conventional, walk-behind power tiller for forming seed rows and adjacent furrows wherein an auger disposed perpendicularly to the seed row being formed has a larger diameter at its proximal ends and a smaller diameter at its central, inner end. The auger is rotated using power derived from the tiller to which the novel seed row forming apparatus is attached. In operation, the larger diameter outer portions of the auger dig a furrow and move the disturbed soil inwardly along the diminishing diameter of the auger, thereby depositing the soil from each side of the auger into a central berm or seed row. The apparatus provides seed row-forming capability for use with small rotary tillers and provides minimum soil tillage while readily forming planting rows. | 04-08-2010 |

20160088786 | ACTIVE COULTER PLANTING SYSTEM - Active coulters are integrated into a planter for a walk-behind tractor. The coulters are “active” (rather than passive) because the coulters are powered (i.e. actively rotated) directly by the walk-behind tractor, rather than passively rolling as the tractor is propelled across a field. The active coulters cut cover crop residue on the surface of the field so that the planter seed drill can plant seeds into the soil beneath the (preferably) flattened cover crop residue on the surface of the field. | 03-31-2016 |

20090241818 | Crop Residue And Soil Conditioning Agricultural Implement - A ground opener that is allowed to caster in one direction is associated with a pair of arms connected by a pivot connection that allows one arm to move relative to the other arm. The movable arm is forced against the stationary arm when the ground opener impacts the soil as the ground opener is pulled along a relatively straight travel path. When the ground opener is turned radially from the straight travel path, the movable arm may cast away from the stationary arm. The disc opener is coupled to the movable arm through a central hub and, as such, the trailing edge of the disc opener will move away from the stationary arm as the disc opener is turned. When the disc opener has completed the turn, the torque on the disc opener will lessen thereby allowing the movable arm to move back toward the stationary arm. | 10-01-2009 |
