Abstract
Apparatus for simultaneously burying multiple strands of tubing in a plowed field. The plowed field includes spaced, elongate, generally parallel upstanding beds. A furrow lies in between each adjacent pair of beds. The apparatus buries tubing in the beds. The conduit has an oblong cross sectional area. The apparatus is designed to prevent the tubing from twisting while being buried in the beds.
