Abstract
An improved high-speed cable-laying apparatus of the type which digs a kerf, lays a cable at the kerf bottom, and refills the kerf with spoil in one pass. The kerf digger is a chainline loop having ground-cutting teeth spaced along its length and restricting elements between the teeth. The chainline is preferably in the form of a narrow upright loop. Rearwardly of the chainline loop are an upright chute for directing cable to the bottom of the kerf and a trailing structure supporting a reel, cable guide means, and angled plow blades for directing spoil back into the kerf on top of the cable. The arrangement of elements is compact and maneuverable and avoids damage to fragile cable even while the device operates at high ground speed.
