Abstract: An extractor for removing agricultural tubing from soil of a field and related methods are provided. The extractor includes a frame and a pivot frame disposed on the frame. The pivot frame can have a pivot axis around which at least a portion of the pivot frame is pivotal. The extractor can include a first roller secured to the frame and a second roller secured to the pivot frame that is moveable by the pivot frame with the first roller being positioned closer to the soil than the second roller so that a tubing to be extracted is threadable under the first roller and over the second roller.
