Abstract: A rotatable plow that includes a pair of oppositely disposed plow members carried on a plow carrier pivotally carried by a draft beam. The draft beam includes a plow carrier adjustment yoke for changing the angular orientation of the plow frame relative to the ground, and thereby also the plow members. A locking arrangement is provided to permit the plow frame to be locked in a predetermined position to selectively present one of a first and a second second plow and moldboard assembly for conducting plowing operations.
Abstract: An elongated ground working tool (12) adapted to be supported at each end in a frame of a ground working implement for rotation about the longitudinal axis of the tool. The toll includes a multitude of tool elements (21) arranged in a plurality of groups (23) in the longitudinal direction of the tool. Each group (23) of tool elements (21) inter-engage with the next adjacent group of form flexible connections between the groups that will permit tensioning of the tool in the longitudinal direction when supported for rotation. The tool elements (21) are so constructed that when the groups of tool elements are inter-engaged and the tool longitudinally tensioned, each group of tool elements presents a plurality of prongs (27) spaced about and projecting outwardly with respect to the longitudinal axis of the tool. A tool element and a ground working implement are also described and claimed.
Abstract: An adjustment means for a cultivator disc which provides lateral, vertical and angular adjustment means. A plurality of discs are mounted in parallel on a gang frame, and may be individually adjusted in the field to exact, predetermined positions established by a positive positioning means, and then firmly held in place by a clamping means. In the presently preferred embodiment, the individual support shafts of each cultivator disc are supported by the angle adjustment brackets, which are supported by the lateral adjustment brackets, which are slidably supported in predetermined fixed positions in lateral housings attached to the main towing bar of the cultivator assembly.
Abstract: This invention relates to a planter guide attachment designed to hold and align conventional corn, soybean planters, or other units on the upper area of a ridge of soil formed by previous cultivation-ridging processes as known in Ridge-Till farming. The unit provides a mounting shaft having a pair of coned blades mounted thereon to allow the tapered faces of the disc blades to hug the sides of the ridges for proper planter alignment. The shaft blade construction is hingedly attached to a mounting bar which is vertically adjustably attached to a tool bar extending transversely of the rear of a towing vehicle for mounting a plurality of guide units thereon. A knee spring-action mechanism is provided to load the shaft, disc structure to maintain the same in ground contacting position, and allow the same to override obstacles that may be in the ridge, and thereafter return the same into ground-contacting position along the sides of the ridge.
