Abstract: A machine for installing drip irrigation conduit consisting of a horizontally extended hose and upright risers spaced along the hose, the machine being adapted to move along a predetermined track of conduit installation; the machine having a pair of coulters and a moldboard disposed to generate a furrow having a vertical wall and an opposite wall at an acute angle to the vertical; a reel for transporting preprepared conduit which is drawn from the reel by previously buried conduit as the machine moves along the track; a pair of downwardly convergent, planar guards extended along the furrow and individually upwardly along respective walls; a wheel disposed between the guards for rotation in a plane parallel to such opposite wall, the wheel having fingers spaced about it circumferentially and extended toward the guard along the vertical wall; elements for guiding the hose from the reel for engagement by the fingers at the lower sector of the wheel to lay the conduit in the bottom of the furrow; elements for gui
