Abstract

A land plane with a ripper, including a plane portion including at least two cutter bars and a ripper mechanism having a ripper bar assembly having ripper teeth that are shiftable between a downwardly extended orientation in which the ripper teeth are biased to extend downwardly beyond the at least two cutter bars thereby facilitating ground engaging contact of the ripper teeth and a retracted orientation in which the ripper teeth are above the at least two cutter bars. The ripper mechanism further includes a latching mechanism and a reset bar extending outwardly away from the plane portion and coupled to the latching mechanism. The reset bar is shiftable between a first position wherein the ripper teeth are secured in the retracted orientation by the latching mechanism and a second position wherein the ripper teeth are biased toward the extended position by the latching mechanism.
