Publication number: 20240057498Abstract: An assembly for an agricultural planter includes a mounting bracket configured for attachment to a frame of the agricultural planter. The assembly further includes an implements frame configured for mounting rotatable implements of the agricultural planter. The assembly further includes a parallel linkage pivotally connecting the mounting bracket to the implements frame. The assembly further includes biasing device having a first end and a second end. The first end is associated with the mounting bracket, and the second end is associated with the parallel linkage such that the biasing device selectively loads the rotatable implements with a threshold load. The biasing device is configured to manipulate the parallel linkage and load the rotatable implements with additional load in excess of the threshold load.Type: ApplicationFiled: August 17, 2023Publication date: February 22, 2024Inventors: Paul E. SCHAFFERT, Kris SCHAFFERT

Publication number: 20230225240Abstract: A press wheel includes a hub configured to rotate about an axis. The press wheel may further include a mounting portion removably attachable to the hub and having a center plane substantially perpendicular to the axis upon removable attachment with the hub. The press wheel may further include a plurality of tread portions connected to the mounting portion and configured to define a circumferential portion of the press wheel. The plurality of tread portions may have voids between adjacent tread portions. Each tread portion of the plurality of tread portions may include a tine extending away from the center plane.Type: ApplicationFiled: January 14, 2022Publication date: July 20, 2023Inventors: Paul E. Schaffert, Kris Schaffert

Publication number: 20220371555Abstract: A wheel scraper for an agricultural planter includes a body defining a mounting portion, a biasing portion extending from the mounting portion, and a tine portion extending from the biasing portion opposite the mounting portion. The mounting portion is configured to couple the wheel scraper to an agricultural planter relative to a wheel on the agricultural planter such that the tine portion is arranged extending adjacent to an outer circumferential surface of the wheel and separated from the outer circumferential surface by a clearance. The biasing portion is configured to resiliently bias the tine portion relative to the outer circumferential surface.Type: ApplicationFiled: May 21, 2021Publication date: November 24, 2022Inventor: Kris Schaffert

Publication number: 20220240439Abstract: A trailing assembly for an agricultural planter is attached to a frame element of the agricultural planter with a mounting bracket. A walking beam having a hub at an intermediate position along a length of the walking beam is pivotably attached to the mounting bracket. A first pair of arms extends from the hub in a first direction, with each arm configured with a shaft to rotatably and selectively receive a first rotating implement, for example, a closing wheel or a fertilizer opener disc. A second pair of arms extends from the hub in a second direction parallel to each other and spaced apart from each other. Distal ends of the second pair of arms are configured to rotatably and selectively receive and support opposing ends of an axle of another rotating implement, for example, a press wheel, positioned between the second set of arms.Type: ApplicationFiled: February 2, 2022Publication date: August 4, 2022Inventor: Kris SCHAFFERT

Publication number: 20220078966Abstract: A furrow closing assembly includes a mounting bracket attachable to a planter opener frame, a rigid closer frame, and a four bar parallel linkage connecting the mounting bracket and the closer frame with a first pivot bearing and a third pivot bearing on the mounting bracket and a second pivot bearing and a fourth pivot on the closer frame. A screw-driven linear actuator extends between the parallel linkage to the closer frame. A shaft of the linear actuator is pivotably attached to a torsion axle that is further fixed to an upper portion of the parallel linkage. A load cell is positioned between the linear actuator and the closer frame.Type: ApplicationFiled: September 14, 2021Publication date: March 17, 2022Inventors: Kris Schaffert, Jerry Graham

Patent number: 11266063Abstract: A press wheel includes a hub which rotates about an axis. A rim extends generally radially from the axis. The rim has a center plane defined as a plane perpendicular to the axis and generally bisecting the rim and defining the center of the wheel. The press wheel includes a plurality of tread portions extending away from the center plane. The plurality of tread portions have voids between adjacent tread portions on the same side of the rim, which in response to the wheel rotating, operably places consecutive adjacent tread portions proximal to the ground. The rim and tread portions are configured to contact the ground.Type: GrantFiled: September 24, 2021Date of Patent: March 8, 2022Assignee: Schaffert Manufacturing Company, Inc.Inventors: Paul E. Schaffert, Kris Schaffert
