ABSTRACT:
In an agricultural irrigation system comprising an elongate wheel line having an elongate, essentially rectilinear, central, water conveying conduit and a series of wheels keyed to and supporting such conduit; the inclusion in said irrigation system of a master or propulsion unit for advancing the line in a direction transverse to the orientation of the central conduit thereof and a series of torquing units or torque booster units mutually spaced along and coupled to said line for applying torque at a series of points remote from the master unit. Each unit may be provided with means for speeding up, slowing down, and stalling out such unit in accordance with requirements for changing the operating conditions of each unit in order to keep the wheel line essentially straight. The entire structure and components thereof serve as a composite, torque-sensing structure so as to be automatically operative to adjust the operation of the booster units and master unit, as needed, so as to compensate for torsion lag, line deflection, and undulating terrain, and so forth, which otherwise would distort the line. Torque resistance sensing is also made a feature of the invention to dramatically alter the fluid flow, for hydraulic operation of one or more of the respective units, so as to compensate for dramatic increases in torquing resistance.
