Poly-pipe handling implement
Abstract:
An implement for handling flexible or collapsible multi ply polyethylene tubing comprising a rigid frame adapted to be secured to a tow vehicle, a powered spool rotatably secured to the frame to receive poly-pipe and an interchangeable retrieval subframe and plow. The frame has a front cross piece, a rigid side rail and a swinging side rail. The spool is mounted between the distal ends of the side rails. A mount on the front cross piece receives the retrieval subframe or plow. The subframe flattens and shapes the poly-pipe for spooling. The subframe comprises a base with arms extending from it. Tension bars extend from one arm to the other. Also, a pair of crossed diagonal cleaning members extend between the arms. The poly-pipe is drawn over the bars and between the cleaning members to flatten and clean the poly-pipe for convenient winding about the spool. The swinging frame rail is swung out to remove or place poly-pipe on the spool. A pillar extends from the base of the subframe to mate with the mount on the front cross piece. A similar pillar extends upward from the plow. To place poly-pipe the plow is used to cut a shallow furrow into which the poly-pipe is laid.
