ABSTRACT The disclosed cable plow assembly is adapted to re- duce the power requirements of cable and line laying plows. The plow blade is suspended on the rear of a resilient frame as- sembly having two pair of vertically spaced links. Each link is pivotally supported on forward and rear frame members by resi- lient torsional bushings. The links of each pair preferrably converge toward the direction of movement of the plow or the sup- porting vehicle at an angle of about fifteen to twenty degrees or about three to four horizontal units to one vertical. This arrangement generates a unique forward elliptical cleaving action in the plow blade, reducing the force required to cut the earth and pull the blade through the ground. In the most preferred embodiment, the forward ends of the lower links of each pair are adjustable vertically to adjust the angle between the links and thereby adjust the elliptical motion of the plow blade to accom- modate various soil conditions.
