Abstract: 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.

Abstract: 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.

Abstract: A plurality of selectively actuable watering stations are spaced about a selected location such as a lawn and/or garden and are connected to a source of pressurized water. A set of data is stored representing environmental conditions of the selected location, said conditions being selected from the group consisting of evapotranspiration rates for predetermined intervals throughout a given time period, and temperature precipitation rates for predetermined intervals throughout a given time period. Another set of data is provided from at least one input device at the selected location, the input device being selected from the group consisting of a temperature sensor, a rain gauge, a hummidity sensor, and a flow meter. Each watering station is actuated for predetermined durations at predetermined intervals based upon the data representing environmental conditions and the input device data to thereby ensure optimum growth of the plants situated in the selected location.
