金毛狮子鱼摘要：A cable laying plow includes a plow shank having a vertically extending forward edge. Sprockets are positioned at the upper and lower ends of the plow shank and a roller chain is supported on the sprockets for movement around a cour including a portion extending along the forward edge of the plow shank. Knife blades are mounted at spaced intervals on the chain, and a stationary cutter bar extends forwardly from the plow shank for cooperation with the knife blades on the chain to effect cutting. A hydraulic motor is mounted on the upper end of the plow shank and drives the chain through the upper sprocket. A plow toe is mounted at the lower end of the plow shank and surrounds the lower sprocket for the protection thereof. The plow toe extends forwardly to a detachable point located substantially forwardly of the forward edge of the plow shank.英语歌词
