Abstract

An extension for use with a furrow opener is disclosed for properly placing seeds in a furrow. The extension attaches by way of particular attachment brackets to the furrow opener to help direct bouncing seeds into the vertex in the bottom portion of the furrow. The extension comprises an elongated flexible body member defining a general arcuate shape, and also defines an upper segment and a lower segment. The upper segment defines an attachment structure for releasable engagement to the furrow opener. The lower segment depends downwardly and rearwardly from the furrow opener and extends into the furrow. The lower segment has a width dimension decreasing continuously along its length, the width dimension substantially equal to but less than the width of the furrow along the length of the extension. The lower segment terminates at a trailing end, which is spaced above the centrally located bottom portion of the furrow.
