A cable burial system (30) includes a cable burial tool (40) having a base frame (54), a blade (56) extending downwardly from the base frame (54) and having a vertically oriented internal slot (58) therein with a slot width, and a feed shoe (70) with an arcuate feed shoe periphery (72) and a feed shoe width less than the slot width of the blade (56). The feed shoe (70) is pivotably connected to the base frame (54) and is pivotable between a lowered position wherein the feed shoe (70) lies within the slot (58), and a raised position wherein the feed shoe (70) lies outside of the slot (58). The feed shoe (70) includes a jet opening (86) in a periphery (72) of the feed shoe (70), and a source of pressurized water in an interior manifold of the feed shoe (70) in communication with the jet opening (86) in the periphery (72) of the feed shoe (70). A guide (88) is operable to guide a cable into the slot (58) in contact with the feed shoe periphery (72) when the feed shoe (70) is in the lowered position. The guide (88) includes a feed horn (90) affixed to the base frame (54) with an outlet end (94) adjacent to the upper end (64) of the slot (58) and centered on the slot (58), and a pair of movable guide plates (100) disposed adjacent to the upper end of the slot (58) and centered on the slot (58). The guide plates (100) are movable between a closed position centered with a first spacing sufficiently greater than the feed shoe width to permit the feed shoe (70) to lie therebetween, and an open position having a second spacing greater than the first spacing. The cable burial tool (40) is pivotably connected to a burial sled (34).
