  • Patent number: 5366023
    Abstract: A wagon pulled along a plant bed for retrieving buried drip tape includes a cultivator disc for loosening the soil to free the drip tape which is then drawn upward and onto the wagon through the use of a rotating drum that rotates at such a speed that its surface moves at the ground speed of the wagon. A wringer wheel that bears against the drum extracts water and air from the drip tape, which is then wound onto a reel under the control of an operator for subsequent storage and reuse. This mode of retrieval is considerably faster than manual retrieval thereby reducing labor cost, and the reuse of the drip tape saves disposal costs as well as material costs and results in conservation resources of the resources used in manufacturing the drip tape.
