Abstract: A pipe laying apparatus comprising a frame mounted on two or more wheels, with a motor and a cutting disk for cutting a narrow slit in the ground. In one embodiment, the apparatus has a blade following the disk and having a conduit on the end with a nozzle on one end of the conduit that issues a jet of water into the bottom of the slit to form a channel. The pipe is attached to the other end of the conduit and is pulled into position in the channel as the apparatus advances. In an alternate embodiment, the apparatus has a winch and pulley used to deploy a wire into the slit as the apparatus is moved forward. The other end of the wire is attached to a nozzle and conduit with the pipe attached in turn to the conduit. When the apparatus is stoppped, the winch rewinds the wire while the nozzle sprays a jet of water in the direction of movement to form the channel and allow the pipe to be easily pulled into position.
