Edge silt-fence installer from CEAttachments cuts a groove and inserts fencing directly into soil. Spring-loaded coulter cuts through surface material and the replaceable blade point digs deep for secure installation, the company says. Attachment handles 36-, 42- and 48-inch rolls, and material travels through a "one-fold" design before being inserted. Adjustable-height fabric roll holder adapts to the diameter of the roll. A 40-degree pivot design allows operators to install fence around tight corners.
