Abstract: An agricultural gauge wheel includes a hub which rotates about an axis, a rim extending generally radially from the axis, the rim defining a circumferential portion and a center plane defined as a plane perpendicular to the axis and bisecting the rim, and a tread including a plurality of tread portions extending away from the center plane to an outer tread edge. The plurality of tread portions define an inside diameter of the tread and the gauge wheel also includes a liner secured to the rim, the liner including an outer diameter less than or equal to the inside diameter of the tread and extending beyond the outer tread edge.

Abstract: Provided herein is a trailing arm assembly that includes a frame bracket attachable to a planter towing frame, a first frame, and a four bar parallel linkage connecting the frame bracket and the first frame with a first pivot and a second pivot on the frame bracket and a first pivot and a second pivot on the first frame. The trailing arm assembly also includes an adjustable biasing member extending from the parallel linkage to the frame bracket. The parallel linkage is connected between the first frame and the frame bracket such that the parallel linkage maintains a parallel orientation of the first frame. The adjustable biasing member is adjustably connected to a portion of the parallel linkage.

Abstract: A closing wheel includes a hub including an outer circumferential hub surface extending a width between a first hub edge and a second hub edge, the first hub edge defining an outer hub diameter. The hub also includes a channel defined by and recessed into the outer circumferential hub surface. The closing wheel also includes a rim configured to couple to the hub within the circumferential channel, the rim including a coupling portion configured to extend into the circumferential channel, a contact portion extending outward from the coupling portion between a first contact edge and a second contact edge. The contact portion defines an outer circumferential wheel surface extending at least the width and between the first contact edge and the second contact edge and an outer rim diameter greater than the outer hub diameter.

Abstract: A bracket for use with an agriculture planter including a trailing arm frame defining a pivot point thereon may include an arm bracket assembly with first and second arms. Each arm may extend from a middle portion of the bracket. First and second implements may be rotatably mounted on mounting ends of two of the arms. The middle portion of the bracket may be pivotally coupled to the trailing arm frame at the pivot point.

Abstract: A closing wheel includes a hub and a rim configured to rotate about an axis and couple to a trailing arm assembly of a tractor. The closing wheel may act to close a seed furrow. The closing wheel may be a modular closing wheel where the hub is defined by portions and the rim is defined by modular pieces. The portions of the hub may define features to support or couple the rim to the hub. The modular pieces of the rim may each connect to an adjacent modular piece. The modular pieces may include radial features extending from the rim and configured to disturb soil.

CPC classification number: A01B63/008 , A01C5/068
Abstract: 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.

Abstract: A linkage assembly for a trailing arm assembly includes a first coupling bracket configured for mounting to a planter or first sub-assembly of the trailing arm assembly, and a second coupling bracket configured for mounting with a second subassembly of the trailing arm assembly. The linkage assembly may further include a parallel linkage pivotally coupling the first coupling bracket and the second coupling bracket. The parallel linkage may be disposed on a center longitudinal plane of the linkage. The center longitudinal plane may bisect the first and second coupling bracket and the second coupling bracket. The linkage assembly may further include a biasing assembly coupled with the parallel linkage and manipulateable to selectively apply a down force to the second coupling bracket.
