An apparatus for installing multiple strands of hose below a surface of terrain is provided. The apparatus comprises a chassis and rotating trenching blade assemblies connected to the chassis. The trenching blade assemblies are configured to dig parallel trenches when the apparatus is pulled along the terrain. Curved hose guides are connected to the chassis in trailing positions behind the trenching blades. Each hose guide receives hose from a hose reel on reel mounts connected to the chassis and deposits the hose into a trench dug by a trenching blade assembly. Trench fillers connected to the chassis trail the hose guides. Each trench filler is aligned with a respective hose guide and comprises a number of blades configured to push soil excavated from a trench back into the trench when the apparatus is pulled along the terrain.
