Abstract
An apparatus for burying filiform objects such as ducts, conduits, cables and the like into the ground. The apparatus has the general appearance of a gasoline-powered manually-driven soil tiller with a V-shaped blade extending into the ground to a predetermined depth. The blade is given a fore-and-aft oscillating movement which temporarily slices a pie-shaped section of the soil as the apparatus progresses over the ground. A chinese finger mounted on the apex of the blade is used to crimp the end of the filiform object which is then pulled under the sliced soil section. Manually controlled clutches allowing the operator to separately activate the forward motion of the apparatus and the vibrating motion of the blade.
