Apparatus and method for installing subsurface tubing

An apparatus for installing multiple strands of hose below a surface of terrain, comprising:

• a chassis having a longitudinal axis and a width;
• a first module coupled to the chassis, wherein the first module comprises:
• a first trenching blade assembly comprising a first trenching blade configured to dig a first trench in terrain along a first trench axis;
• a first hose guide configured to guide hose into the first trench;
• and
• a first trench filler-packer, wherein the first trench filler-packer is configured to dispose soil excavated from the first trench back into the first trench and to pack at least a portion of the soil disposed back into the first trench;
• a second module coupled to the chassis, wherein the second module comprises:
• a second trenching blade assembly comprising a second trenching blade configured to dig a second trench in the terrain along a second trench axis;
• a second hose guide configured to guide hose into the second trench;
• and
• a second trench filler-packer, wherein the second trench filler-packer is configured to dispose soil excavated from the second trench back into the second trench and to pack at least a portion of the soil disposed back into the second trench;
• wherein a lateral spacing between the first trench axis and the second trench axis is adjustable.
