| 93 | Disc Mounting Assembly for a Vertical Tillage Implement | US14253538 | 2014-04-15 | US20150289434A1 | 2015-10-15 | Johan Redekop |
| In a disc assembly for supporting a ground engaging disc on a respective support arm of a vertical tillage implement, the disc supporting hub has an annular body rotatably supported on a shaft. The outer end of the annular body is enclosed by a cap and the inner end of the annular body is enclosed by an end plate fixed on the shaft relative to which the annular body is rotated. First and second annular flanges on the inner end of the annular body receive a tongue portion of the end plate therein so as to define a sinuous, narrow clearance gap where the annular body of the hub and the end plate of the shaft are in a non-contacting, rotatable relationship with one another. The sinuous, narrow clearance gap minimizes penetration of soil and residue therethrough to the interior of the hub where bearings are located. | ||||||

| A composite working tool, for example a ground engaging tool of an agricultural implement, features a body composed of a first material and an insert composed of a distinct second material of greater hardness than the first material to define wear resistant surfaces of the tool. The tool body has an opening recessed thereinto from an exposed exterior surface fully surrounding the opening on all sides thereof, and the insert is attached to the body in a position at least partially received within the opening, for example by brazing. The increases the wear life of the body and provides greater mounting strength over surface-mounted wear inserts of the prior art. | ||||||

| A closing tool to be attached to a plough frame to engage a soil layer, the tool includes an attachment stem via which the closing tool is attached to the plough frame. Secured to the lower portion of the stem are wear resistant members. | ||||||
| 96 | Tool mounting assembly | US400375 | 1989-08-30 | US4976566A | 1990-12-11 | Allan J. Yeomans |
| An assembly for mounting an earth working tool to a shank having a substantially vertical track on the rear end of the shank, a tool holder having a C-shaped opening at its forward end and adapted to fit over the shank track, and a wedge member adapted for wedging between the shank track and the tool holder to secure the holder to the shank at a selected position with the track forward facing surfaces engaging the flange rear surfaces. The track includes a rearward V-shaped surface and a pair of forward facing surfaces and the holder opening includes a flanges adapted to engage the forward facing surfaces when forced together by the wedge member. Depressions and protrusions are provided on the flanges and forward facing surfaces to secure against vertical movement of the mounted holder relative to the shank. The V-shaped surface has an included angle of substantially ninety degrees. The wedge member includes a striker plate having a first surface which may be struck from the top to secure the holder to the shank track and a second surface which may be struck from the bottom to disengage the holder from the shank track. | ||||||

| The problem of having dirt and debris stick to the shank of a subsoil plow is solved by providing a non-stick cover body that attaches to a lower portion of the shank and is sized and configured and of a material to which dirt and debris will not adhere. Fasteners in the form of staples insert into holes in laterally spaced tail edge portions is provided. The body is made of a sheet of ultra high molecular weight-polyethylene that is sized, and then bent around a mandril, heated, then cooled and machined as required to be generally complementary with the shape of the lower portion of the shank to which the body is fastened. | ||||||
