  • Patent number: 4179227
    Abstract: A plow assembly and method useful for burying an elongated flexible member at a predetermined depth beneath ground level. The arrangement utilizes a frame assembly adapted to be pulled by a tractor type vehicle and which frame assembly has a vertically-extending plow support unit. A dynamic plow unit is mounted at the lower end of the plow support unit and includes a generally horizontal base. The forward end of the plow unit includes a plow nose portion having an inclined top surface. The top of the plow unit is defined by a plate member having an upper surface which extends rearwardly from the nose generally parallel to the base. The plate member is mounted about a transverse axis closely adjacent the nose portion for pivotal oscillating movement by hydraulic cylinder means. Such oscillation is between a first position generally parallel to the plow unit base and a second position spaced angularly upward therefrom.
