ABSTRACT:
The application discloses a multi-row plow adapted to be towed behind a small walking tractor. The plow comprises a draft frame having a pivotal attachment to the tractor and a tool frame. At the rear of the tool frame there is a ground engaging wheel. Apparatus is provided to change the elevation of the wheel relative to the draft frame, thereby to adjust the elevation of the rear end of the draft frame. Linkage causes the forward end of the tool frame to be raised when the rear end of the draft frame is raised, and vice versa. The foregoing provides a simple and labor-saving way of removing the tool from the ground at the end of the row for turning the apparatus around.
