An irrigation system is disclosed. The system features a pair of lines placed generally parallel and proximate to each other in the subsurface. Only one of the lines is directly connected to the water source. The other line serves as an auxiliary to permit the system to be flexibly adapted or expanded to meet changing irrigation demands or landscape conditions. The auxiliary line is separated into discrete segments, each segment pertaining to a selected zone or area to be separately irrigated. Feeder lines run from each discrete segment to sprinklers. Water is provided to the segments via valved bridges extending from the main line to the segment, so that water flows to the segments only by way of the bridges, the bridges permitting separate segments to be activated in a planned manner. The system using dual lines selectively connected by valved bridges at selected points permits the system to be expanded or adapted by the provision of additional separate segments in the auxiliary line connected to the main line by a bridge. The two lines ideally are made from polyethylene, permitting rapid and inexpensive installation of the system. Various tools customized for easy installation of the system are disclosed.

Irrigation system, apparatus, and method

A self-propelled, and winch assisted, steerable vibratory plow for laying underground pipe or cable, having a V-shaped blade connected to an oscillator which provides both elliptical and horizontal plow blade motion as needed, and with auxiliary straight blade plows for laying lateral lines on the sides of the main line. The main plow's gasoline engine powers a hydraulic system which powers the winch and a transaxle connected to the forward drive wheels, and powers the oscillator and a steering cylinder, as well as powering a hydraulic cylinder for lowering and raising the plow blade.
