摘要： 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. Plate member oscillation generally ranges from 20 to 120 cycles per minute with the upward portion of each oscillation being slower than the downward or return portion. The plow nose portion may include a vibrator or a lubricant release for reducing sliding friction. For operating at increased depths a pair of in line, cooperating frame assemblies which are horizontally and vertically spaced apart from each other may be employed.
