Abstract

A bi-directional sled includes a support structure and a shroud assembly. The shroud assembly is supported to the support structure for pivotal movement about an axis extending through the support structure between a first orientation and a second orientation. The shroud assembly has a shroud with a first edge and a second edge opposite the first edge. With the support structure moving the shroud assembly in the first direction relative to material to be dredged friction between the shroud assembly and material to be dredged pivots the shroud and the first edge into a first orientation to contact material to be dredged. With the support structure moving the shroud assembly in the second direction relative to material to be dredged the shroud and second edge are pivoted into a second orientation to contact material to be dredged.
