摘要：

A plurality of trough extruders are supported upon a lift truck traveling in a circular travel path. The plurality of trough extruders continuously form one piece troughs as the lift truck travels its circular path. A lift mechanism progressively raises the extruders as the lift truck travels its circular path two form continuous one-piece helical water troughs for use in an agricultural growing structure.
