An erosion fence installation attachment for ditchers and trenchers that is short in length and articulated to pivot in pitch and yaw so as to permit the attachment to follow a ditcher through gullies over mounds and around arcs. The attachment is provided with a barrier material roll unwind, a resilient guide that guides the barrier material into a ditch formed by the ditcher so that the barrier material is pressed against the sides and bottom of the ditch to form an open channel, a first ditch fill disk that pushes fill material into the ditch and into the channel formed in the barrier material, a second ditch fill disk that pushes fill material from the opposite side of the ditch and onto and over the barrier material on that side of the ditch to form a wrap around the fill material deposited by the first fill disk so as to form an elongate anchoring pouch filled with fill material along the bottom of the ditch. A stake driven along one side the above ground portion of the barrier material will penetrate at least two layers of the barrier material further securing the anchor in place. To form a barrier fence, the barrier material is secured to the stake by conventional means.
