Title: Cable laying vibratory plow assembly

Abstract: A plow assembly for cutting a slit in the ground and simultaneously laying a cable in the slit as the propelling vehicle moves over the ground. The plow assembly has a shaker case containing a pair of counter-rotating eccentric weights for providing a vibratory action to the plow, additional weight means are located rearwardly of the plow and plow frame so as to reduce the amplitude of vibration at the rear end of the assembly, and the assembly also has elastomeric isolation mounts for the shaker case on the plow frame so that the resulting action of all the components is such that the plow blade pivots about a pivot point located rearwardly of the assembly and in a particularly efficient arcuate cutting movement.
