摘要： 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.

摘要： 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.

摘要： An agriculture planter includes a planter frame, a seed hopper, and a trailing arm assembly. The planter frame may include a hitch tongue extending forwardly from the planter frame. The trailing arm assembly may be coupled to a rear portion of the planter frame via a parallel linkage and extend rearward from the planter frame, and include separate but adjustable trailing arm assemblies for the opening implements and the closing implements.

摘要： 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.

摘要： 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.

摘要： 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.
