Abstract: A drawn moldboard plow includes a lift linkage for the rear furrow and ground wheels which improves ground penetration by causing the plow frame to roll as it is lowered so the share points contact the soil first. A hydraulic cylinder contained within a part of the frame operates both the furrow and the ground wheels through a linkage which, during retraction, raises the ground wheel at a faster rate than the rear furrow wheel so the plow frame rolls in the direction of the ground wheel. If the ground wheel reaches its plowing position determined by an adjustable stop before the furrow wheel, a lost motion connection allows continued retraction of the cylinder to further raise the furrow wheel to its plowing position.

Abstract: An angularly adjustable bracket structure is provided for mounting tool-carrying standards on the frame of an agricultural implement. The bracket structure includes a bracket having three adjoining vertical faces which are angularly offset from one another and which can be abutted to the frame to adjust the tool between three positions and provide selected widths of cut between the tools. A wedge element is removably insertable between the frame and two faces of the bracket to position the third face in abutment with the frame.
