ABSTRACT:
This invention relates to an attachment for conventional planters that will convert them to ridge-till planters at reasonable costs. It consists of a pair of laterally spaced vertical mounting bars, fastened suitably at their upper end to the parallel linkage of a planter, extending downward to connect pivotally to the rearward end of a horizontal L-shaped parallel linkage, whose forward ends connect pivotally to the horizontal frame of this invention called the ridgemate. At the forward end of the horizontal frame is a drum wheel that runs on top of a ridge and gives constant height to the horizontal support frame. To the rear of the drum wheel is a pair of disk openers, adjusted in depth by a tubular screw arrangement. Following closely and to the rear of the disk openers is a sweep to widen and further clean off the ridge. The sweep also is adjusted in its operating depth by a tubular screw arrangement. The L-shaped parallel linkage allows the ridge trimmer to operate independently of the planter units to which it is attached. Because of the L-shaped parallel linkage and the positive depth settings available, the ridgemate will proceed ahead of a planter unit (to which it is attached) and cut off a ridge in a completely controlled manner, providing ideal planting environment for the planter that follows.
