20100276204 | VIBRATING TOOL - A vibrating tool comprising a hammer and valve that oscillate axially inside a housing to produce vibrations solely in response to fluid flow through the tool at an operating flow rate. The valve is supported by a spring that resists compression until a minimum operating flow rate is achieved, and hammer is also spring-loaded. When the valve strokes down and engages the hammer, flow through the hammer is restricted. Increased fluid pressure pushes the hammer down away from the valve, resulting in a sudden decrease in pressure, allowing both the hammer and valve to rebound and create vibrational impacts. The cycle repeats continuously as long as an adequate flow rate is maintained. | 11-04-2010 |

20120061113 | Structure for Attaching a Tool to a Frame Tube - Gang tube rail structure is attached to the lower front and rear corners of the implement gang tube to provide a lower clamp support. Two pivoting clamp jaws are attached to the clamp support and secured against the support by tightening a single clamp bolt extending between the lowermost portions of the jaws. A locator shoe is secured between the tube and the c-spring and includes a protrusion that projects into a hole in the c-spring. The ends of the locator shoe include short legs that wrap around the gang tube rail. The single clamp bolt provides a vertical clamp force that is approximately twice the tension generated in the bolt when the nut is tightened. | 03-15-2012 |
20130048324 | AGRICULTURAL IMPLEMENT STANDARD MOUNT - An agricultural implement including a coupling mechanism for coupling to a vehicle and a frame having a tool tube with a top, which is coupled to the coupling mechanism. The frame is adapted to be pulled by the vehicle. The agricultural implement includes a plurality of wheel assemblies coupled to the frame, which support the frame above a surface. The agricultural implement includes a tool tube bracket coupled to the tool tube. The agricultural implement includes a standard having a mounting portion and a tool-receiving portion. The mounting portion is coupled to the tool tube bracket for translational adjustment of a position of the standard relative to the tool tube. The agricultural implement includes a tool coupled to the tool-receiving portion of the standard. | 02-28-2013 |
20130062084 | AGRICULTURAL IMPLEMENT ROLLING BASKET SUPPORT - A rolling basket support for coupling a rolling basket to an agricultural implement is disclosed. The rolling basket support includes a center portion having a bearing mount. A periphery extends radially around the bearing mount. The periphery has a radially inner notch for coupling to ground-engaging bars of a first cross-section and a radially outer notch for coupling to ground-engaging bars of a second cross-section. | 03-14-2013 |
20130062085 | DISK GANG BOLT TENSIONING STRUCTURE - An agricultural disk gang includes an elongated disk gang bolt having a threaded end with an externally threaded surface. A plurality of cultivating disks are supported on the disk gang bolt. A nut is threadably engaged with the externally threaded surface. The nut has a first side facing the disks and a second side facing away from the disks. The nut is disposed to axially compress the disks together on the disk gang bolt when tightened. A tensioning structure is mounted on the disk gang bolt outside of the nut. The tensioning structure has a plurality of threaded through holes. A plurality of threaded fasteners are threadably engaged with the threaded through holes and are disposed to axially compress the disks when the plurality of threaded fasteners are tightened, thereby permitting the nut to be further tightened. | 03-14-2013 |
20130180741 | FRAME SECTION PIVOT LIMITING DEVICE - A pivot limiting device for an agricultural implement is disclosed. The agricultural implement includes a first frame section pivotally coupled to second frame section at a pivot location. The device includes a compression structure having a spring compressed to a preset load. The compression structure is coupled to the first frame section. A plunger includes a first portion positioned adjacent the second frame section and a second portion positioned adjacent the compression structure to move relative thereto between a first position placing no additional compression on the spring when the second frame section pivots in a first direction and contacts the plunger with a first force less than or equal to the preset load, and a second position further compressing the spring when the second frame section pivots in the first direction and contacts the plunger with a second force greater than the preset load. | 07-18-2013 |
20140209335 | DRAWBAR APPARATUS OF AN AGRICULTURAL IMPLEMENT - A drawbar apparatus for coupling an earth-working tool to a frame of an agricultural implement. The drawbar apparatus comprises a drawbar. The drawbar comprises a first portion coupled to the frame and a second portion. A joint comprises a first bracket comprising a protrusion. The protrusion defines a first aperture. The first bracket is coupled to one of the second portion of the drawbar and the earth-working tool. A second bracket defines a channel configured to receive the protrusion. The channel defines a second aperture on a first side of the channel and a third aperture on a second side of the channel. The second bracket is coupled to the other of the second portion of the drawbar and the earth-working tool. A fastener is positioned through the first aperture, the second aperture, and the third aperture. The protrusion is configured to move laterally in the channel. | 07-31-2014 |
20150323012 | SEAL ASSEMBLY FOR BEARINGS - A seal assembly is disclosed for a bearing having first ring with a first inner surface, a second ring with a second inner surface, and at least one bearing member disposed between the first and second inner surfaces. An exterior seal with a first plurality of lips is attached to an exterior backing, the exterior backing engaging the first ring of the bearing to hold the first plurality of lips against the second inner surface of the second ring. An interior seal with a second plurality of lips is attached to an interior backing, the interior backing engaging the second ring of the bearing to hold the second plurality of lips against the first inner surface of the first ring. The second plurality of lips may be configure differently than the first plurality of seal lips. The interior backing may be oriented between the exterior seal and the interior seal. | 11-12-2015 |
