1. Apparatus for inserting into the ground a longitudinal edge portion of an elongated strip of flexible silt fence material extending from a supply roll, said apparatus comprising
a frame including a connector for connecting said apparatus to a vehicle, said frame supporting a shaft having an axis and supporting a supply roll of said silt fence material, a vertical plow plate supported by said frame and having a forward edge surface and an inclined linear rearward edge surface, said frame and a lower portion of said plow plate supporting a foldover member, positioned behind said rearward edge surface of said plow plate and defining a gap between said foldover member and said rearward edge surface, said gap adapted to receive said silt fence material extending from said supply roll and for folding the material around said foldover member with an edge portion of the material extending into a slit formed into the ground by said plow plate in response to forward movement of said apparatus with the vehicle, a flexible and resilient elastomeric protector panel connected to said plow plate and projecting rearwardly from said rearward edge surface and positioned adjacent said silt fence material entering said gap and within the slit in the ground, and said protector panel being effective to block rocks and debris from entering said gap with said material and prevent disrupting the movement of the material through said gap. |
