Abstract
A tool forms and shapes raised beds efficiently by forming and shaping a mound between the tractor tires and forming half mounds to the left and right of the tractor on one pass. The tool includes forward and rear disks mounted at different angles, so that one disk throws dirt to one side and the other disk throws dirt to the other side.
