| 81 | DISK DEVICE FOR AN AGRICULTURAL MACHINE | US14770723 | 2014-03-07 | US20160014951A1 | 2016-01-21 | Crister STARK; Mikael EDVINSSON |
| A disc device for an agricultural machine includes at least one disc implement, an arm, at one end of which the implement is journalled in bearings at an axle, and a bearing, which is arranged at the opposite end of the arm and is adapted to be fastened at a transverse beam on the frame of the agricultural machine. The disc device includes in the circumference direction of the disc implement mainly equally distributed, freestanding, out towards the periphery radially extending, protruding parts, wherein each protruding part has an outer edge, which extends in the range 15-75 degrees in relation to the plane of the disc implement. | ||||||
| 82 | GROUND ENGAGING ASSEMBLY FOR APPLYING FORCE TO GROUND AND GROUND ENGAGING VEHICLE INCORPORATING SUCH ASSEMBLY | US13911822 | 2013-06-06 | US20130327203A1 | 2013-12-12 | Richard Leonard Cronk |
| A roller assembly for applying force to the ground is disclosed. The assembly includes a body adapted to be mounted to a vehicle for moving the assembly, and supports including a first support member supporting a plurality of rollers for applying force to the ground, and a respective piston connected to each roller, the rollers connected via a respective pressure chamber to the corresponding first support member to resist movement of the pistons towards the first support member. The first support member pivotably connected to the body via a first axis such that pivoting movement of the first support member about the first axis as a result of a first torque about an axis has a component about an axis transverse to the direction of travel such that engagement of the rollers with the ground causes a second torque on the first support member opposing the first torque. | ||||||

| A low till agricultural implement has a frame with a hitch for attachment to a tractor. An shallow-angled blade gang composed of an array of parallel ultra-shallow inclined disk blades is mounted to the front of the frame, and is followed by at least one wheel, spiral reel, and spike tooth harrow. The ultra-shallow inclined disk blades are mounted perpendicular to rotating shafts, and slice through field residue and soil with minimal lateral movement of material. The blades of the following reel then make cuts nearly perpendicular to those made by the circular blades. A trailing rolling basket or other finishing implement follows the spiral reel. The implement aids in drying the soil surface layer. Also, by cutting up residue and evenly spreading debris and topsoil, the implement helps to warm up the soil. | ||||||
| 84 | Soil Conditioning Device | US12345180 | 2008-12-29 | US20090200049A1 | 2009-08-13 | Charles Stephen Carr; Keith Ward |
| The instant invention is of a soil conditioning device having a series of peripheral ridge members having a leading and trailing prow shaped surface circumscribing a disc, wheel or drum. Optionally the prow shaped peripheral ridge members are joined by sub-ridge members forming a single ridge of varying heights circumscribing the disc, wheel or drum. The invention is also of a method for creating a permeable soil surface using the apparatus herein. | ||||||
| 85 | Rotary crimping apparatus for elevated crop beds | US12212342 | 2008-09-17 | US07562517B1 | 2009-07-21 | Ted S. Kornecki |
| The rotary crimper for elevated crop beds is designed to crimp and mulch a field of crops with an elevated bed-type structure. The rotary crimper has a tubular inner roller and a plurality of crimping members extending from the inner roller. The crimping members have at least two projecting portions and at least one non-projecting portion. Structural support braces are disposed between the crimping members and crimping plates extend from the support braces. Additional crimping structures also extend the length of the inner tubular roller between the crimping members. In operation, the non-projecting portions of the crimping members and the crimping structures crimp the crops on the elevated portion of the beds, and the crimping member projecting portions and the crimping plates crimp the crops in the furrows between the elevated beds. | ||||||
| 86 | Soil conditioning device | US11176569 | 2005-07-07 | US07478684B2 | 2009-01-20 | Keith Ward |
| A soil conditioning device having a series of peripheral ridge members having a leading and trailing prow shaped surface circumscribing a disc, wheel or drum and a method of use. Optionally the prow shaped peripheral ridge members are joined by sub-ridge members forming a single ridge of varying heights circumscribing the disc, wheel or drum. | ||||||
| 87 | Midrow levelling attachment for a seeder | US10864451 | 2004-06-10 | US06945182B1 | 2005-09-20 | Duane Haukaas; Greg Haukaas |
| A midrow levelling attachment for a seeder includes a set of leveller gangs each of which is mounted on a respective one of the packer wheel gangs of the seeder by a pair of mounting members one at each end of the common shaft of the leveller gang. The levelling roller gang is arranged such that each roller has the peripheral surface thereof located at a position aligned with a location on the ground between a respective pair of the shanks of the seeder and each roller is located rearwardly of the respective pair of shanks and in front of the packer wheels for engaging the ground between the furrows formed by the furrow forming element of the respective pair of shanks. The peripheral surface of each levelling roller is shaped with an apex and two inclined sides such that as the peripheral surface rolls over the ground between the furrows it tends to push the soil back into the furrows. | ||||||
| 88 | Device for crushing stubble | US454550 | 1995-05-30 | US5725057A | 1998-03-10 | Kenneth Noel Taylor |
| A device for crushing stubble comprising a rotatable crushing element supported by a frame. The frame is coupled by a pivotable connection to a drive mechanism which moves the device in a predefined direction across the stubble. The pivotable connection allows the crushing element to pivot about an axis substantially parallel to the predefined direction of motion so that substantial contact is maintained with the ground, thereby maximizing the extent of crushing. Limited vertical movement of the crushing element is permitted by a suspension mechanism. | ||||||
| 89 | Rotary stalk chopper apparatus | US923061 | 1978-07-10 | US4150724A | 1979-04-24 | Dwight W. Strobel |
| A tongue drawn rotary apparatus for chopping vegetation and for churning and working the soil, including individually supported shredder reels mounted on a frame, which frame may be lowered and raised in response to a wheel retraction and extension rocker mechanism, which mechanism also provides firm and resilient support to the tongue. | ||||||
