| A finishing attachment for a tillage implement has a support arm configured to mount to the frame so that a long dimension of the support arm extends in a fore-aft direction of the implement. A cross-bar having a long dimension extending transverse to the fore-aft direction is coupled to a free end of the support arm. A roller basket is mounted to the cross-bar for rotation with respect to the cross-bar. A pivot bracket couples the free end of the support arm to the cross-bar. The pivot bracket forms a pivot axis extending substantially in the fore-aft direction of travel about which the roller basket pivots. | ||||||

| A multi-piece cutting edge attachment for a circular shaft of a harrow tine features a mounting member formed of a material that is weldable to, and distinct from, a first material of the harrow tine. A cutting edge member is formed of a third material that is harder than the first and second materials and less weldable to harrow tine than the second material of the mounting member. The cutting edge member has a front face and an opposing rear face that is conformingly shaped for placement against a front face of the mounting member at a lower end thereof. The multi-piece arrangement forms a cutting edge of greater hardness than that which is achievable by a material directly attachable to the tine itself. | ||||||

| 90 | Structure for attaching a tool to a frame tube | US12878617 | 2010-09-09 | US08322454B2 | 2012-12-04 | Richard J. Connell; Ryan A. Hackert; Mark D. Beeck |
| 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. | ||||||

| A harrow is provided having an elongate tool bar mounted on wheels for movement in a forward direction perpendicular to the tool bar. A plurality of harrow elements are mounted on the tool bar to extend generally rearward therefrom. A pair of support arms are pivotally mounted on the tool bar at a first end and mount each harrow element on a second end towards a rearward end of the harrow element. A hanger is connected between the support arms and the harrow element towards a forward end of the harrow element for suspending the harrow element therefrom. A plurality of tines are mounted on the harrow element such that the angle of the tines relative to the ground may be adjusted. A coupling connects between the hanger and the tines such that the height of the front end of the harrow frame is adjusted in response to tine angle adjustment. | ||||||

| A harrow comprises an elongate tool bar formed in three sections including a central section and two wing sections all of which can rotate about a longitudinal axis, The wing sections are coupled by pivot couplings which allow the wing sections to fold rearwardly in the transport position. The tool bar carries a number of harrow elements each of which is formed by a rigid frame defined by longitudinal rails and welded cross bars with the frame carrying a plurality of tine support bars. A push rod simultaneously rotates all of the tine support bars about their respective axis to vary the angle of the tine in contact with the ground. The angle of the tines of all of the harrow elements are adjusted simultaneously by a number of rocker shafts mounted on the tool bar and operated by rephasing cylinders. Each push bar of each harrow element is attached to the respective rocker shaft for actuation. The harrow frame is mounted on a bracket passing underneath the square section tool bar and pivots about a horizontal axis just rearward of the tool bar with tension springs forwardly of the tool bar pulling the frame upwardly. The tool bar can be rotated beyond the horizontal position to apply downward pressure on the harrow frame against the ground. | ||||||
| 93 | Replacement tips for spring harrows | US500202 | 1990-03-28 | US5027907A | 1991-07-02 | Garth Delyea |
| The invention is designed primarily for use with resilient tine components which include a pair of resilient spring coils having an attaching U extending between adjacent ends and a resilient tine extending from the outer end of each of the resilient coils substantially perpendicular to the longitudinal axis thereof. These often wear and the most expensive replacement cost is the resilient spring coils. The present invention overcomes these disadvantages by provided a sleeve which engages over the worn ends of the tines and is secured thereto and which has a replacement tine portion secured within the other end of the tubes and extending axially therefrom thus returning the tines to their original length. The sleeves can be secured to the worn ends of the tines either by welding, set screws or other means. | ||||||

| A vertical rod extending downwardly through a pivot bearing on the end of the drawbar arm and is connected to the harrow section. A cable is secured to the top of this rod and extends downwardly to the drawbar arm, around a sheave thereon, and along the arm to a tension spring secured to the arm. Rotation of the drawbar arms downwardly thus extending the spring and transferring this pressure via the cable to the top of the rod which in turn presses the harrow sections into the ground.
