DESIGN AND DEVELOPMENT OF A SUBSURFACE TRICKLE LATERAL EXTRACTION DEVICELorenzen, Bruce Robert, 1959- January 1987 (has links)
A tractor mounted three-point hitch implement was developed to extract and collect subsurface trickle irrigation laterals from the soil. Power to the implement was supplied by the tractor hydraulic system to the three-point hitch and two remote hydraulic circuits. In operation, the implement loosened the soil around the lateral, extracted the tubing from the soil, wound it on a reel assembly, and then dropped the roll of tubing at the end of the row. Draft power requirements averaged 14.5 kW (19.4 hp) and hydraulic power averaged 0.56 kW (.75 hp) when the one row implement was operated at 7.2 km/h (4.5 mph). Field capacity of the one row implement averaged 0.19 ha/hr (.47 ac/hr) when operated in 100 m (328 ft) long rows.
