Abstract
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.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
155 words
An attachment for a planter designed to plant on level ground to adapt the planter to plant along ridges, said planter including a transversely extending tool bar having at least one planter unit secured thereto by laterally spaced upper and lower arms arranged in a parallelogram type linkage, said attachment comprising a pair of laterally spaced vertically extending mounting bars each having spaced apart openings to align with and pivotally attach to the upper and lower arms of the parallelogram linkage, the lower end of each said mounting bar pivotally mounting a rearward end of a forwardly extending parallelogram linkage comprising a plurality of arms attached at their forward ends to a vertical outer frame portion of a generally horizontally extending main frame, said main frame including a forward centrally mounted gauge wheel, a pair of forwardly and downwardly converging discs aligned with said gauge wheel, a sweep mounted behind and aligned with said discs.
Claim 2
Dependent Claim
155 words
An attachment for a planter designed to plant on level ground to adapt the planter to plant along ridges, said planter including a transversely extending tool bar having at least one planter unit secured thereto by laterally spaced upper and lower arms arranged in a parallelogram type linkage, said attachment comprising a pair of laterally spaced vertically extending mounting bars each having spaced apart openings to align with and pivotally attach to the upper and lower arms of the parallelogram linkage, the lower end of each said mounting bar pivotally mounting a rearward end of a forwardly extending parallelogram linkage comprising a plurality of arms attached at their forward ends to a vertical outer frame portion of a generally horizontally extending main frame, said main frame including a forward centrally mounted gauge wheel, a pair of forwardly and downwardly converging discs aligned with said gauge wheel, a sweep mounted behind and aligned with said discs.
Claim 3
Dependent Claim
17 words
The invention defined in claim 1 wherein the discs are vertically adjustably mounted on said main frame.
Claim 4
Dependent Claim
55 words
The invention defined in claim 2 wherein the mounting for vertical adjustment includes an outer shell member having an elongated slot along one side thereof, an inner shell slideably adjustable within said outer shell and including a pair of axles secured to a plate attached to said inner shell and projecting outwardly through said slot.
Claim 5
Dependent Claim
21 words
The invention defined in claim 1 wherein the sweep includes a mounting permitting vertical adjustment with respect to said main beam.
Claim 6
Dependent Claim
68 words
The invention defined in claim 4 wherein the sweep mounting includes an upper shell secured to said beam, an inner shell slideably adjustable within said outer shell, a slot along one side of said outer shell, a plate member secured to said inner shelf and extending outwardly through said slot, said plate including fastening means for securing said sweep in a plurality of upwardly or downwardly inclined positions.
Claim 7
Dependent Claim
152 words
An attachment for a planter designed to plant on level ground to adapt the planter to plant along ridges, said planter including a transversely extending tool bar having at least one planter unit secured thereto by laterally spaced upper and lower arms arranged in a parallelogram type linkage, said attachment comprising a pair of laterally spaced vertically extending mounting bars having spaced apart openings to align with and pivotally attach to the upper and lower arms of the parallelogram linkage, the lower end of each said supporting bar pivotally mounting one end of a forwardly extending parallelogram linkage comprising a plurality of arms attached at their forward ends to vertical portion of a generally horizontally extending main frame, the arms of said attachment linkage constructed as L-shaped members with the back side of the L-shape opposing one another whereby said back sides will abut to limit downward movement of said main frame.
Claim 8
Dependent Claim
152 words
