An erosion control apparatus includes a flexible, container and a cord. The container includes a container upper side, a container lower side opposite the container upper side, a container trailing end, a container leading end opposite the container trailing end, and a container mouth toward the container leading end. The container mouth provides an opening to a container interior. The cord is attached between the container mouth and an attachment point toward the container trailing end. The cord draws the container mouth toward the container trailing end due to a length of the cord between the container mouth and the attachment point being shorter than a length of the container between the container mouth and the attachment point. The cord further draws the container mouth toward a closed position as sediment enters the container mouth, fills the container interior, and urges the container leading end away from the attachment point.

A retractor system includes a retractor blade and a retractor arm having a side-load connector. The side-load connector includes a port that passes through an upper surface and a lower surface of the side-load connector. A sidewall opening in the side-load connector permits lateral passage of the attachment post through a sidewall to the port. The side-load connector includes a cam pivotably coupled between the lower surface and the upper surface and a spring that applies a biasing force on the cam. The biasing force biases the cam to a closed position in which the cam extends into the opening and prevents unloading the attachment post from the port via the opening. The cam selectively engages either a first groove or a second groove of the attachment post sidewall. The side-load connector further includes teeth that engage teeth of the retractor body when the cam engages the first groove.
