Abstract: A water supply system is described for supplying water to a linearly moving irrigation system. The water supply system is able to take water from a stationary water supply conduit (either a collapsible conduit or a rigid conduit) and feed it into one end of a feed pipe for the irrigation system. The water supply system includes a pickup shoe which extends into the water supply conduit through a traveling opening in the top side of the conduit. The pickup shoe intercepts substantially all of the water in the supply conduit and pumps it upwardly through the traveling opening to the feed pipe for the irrigation system. The pump is located in the portion of the shoe which extends into the supply conduit.

Abstract: A drag hose assembly includes a first pivot point, a first boom, a second pivot point, a second boom, and a fluid flow path. The first boom is pivotally attached to the first pivot point so that the first boom can pivot about the first pivot point, and the second boom is pivotally attached to the second pivot point so that the second boom can pivot about the second pivot point.

Abstract: An apparatus for application of a liquid or liquid-solid solution to soil includes an articulating tractor, a frame, a pivot point, a boom and a drag hose. The articulating tractor has a front portion and a rear portion connected to an articulation point. The rear portion has a rear wheel axle. The frame is adapted to mount on the rear portion of the articulating tractor. The frame has a front frame end located between the rear wheel axle and the articulation point. The pivot point is on the front frame end and positioned about 12 inches or more from the rear wheel axle. The boom pivotally attaches to the pivot point. The drag hose has a distal end in fluid communication with a source of liquid or solid-liquid solution and a proximal end coupled to the boom.

Abstract: A chemical dispenser which is selectively removably mounted on a travelling lawn sprinkler. The chemical dispenser dispenses liquid chemical into the water being sprinkled onto the lawn by the water distributor as the self-propelled travelling lawn sprinkler propels itself across a lawn.

Abstract: Aspects of the invention relate to a sprinkler apparatus providing multiple operational modes. For instance, the apparatus can operate as a conventional traveling sprinkler. In addition, the apparatus can provide one or more additional ports so that a user can attach additional hoses or other watering or irrigation equipment. The apparatus can include a switch so that a user can selectively switch a valve so that a fluid flows substantially exclusively to one of these additional ports. In one embodiment, a hose or other fluid dispensing device can be attached to one of the additional ports so that an operator can wash a car, water hanging pots, or perform other watering functions that cannot be accomplished by a traveling sprinkler.

Abstract: A lawn irrigation system including a frame, a motor, a sprinkler arm, at least one drive wheel, and a cover. The motor is operably attached to the frame. The at least one drive wheel is operably connected to the motor. The sprinkler arm is operably connected to the motor for dispersing water in a selected pattern. The cover is attached to the frame so that the cover at least partially covers the frame, the motor, and the at least one drive wheel so that the lawn irrigation system resembles an object other than a sprinkler.

Abstract: A gearbox for a drive line irrigation system in which the input and output shafts of the gearbox are sealed with a compressed and sintered silicon and carbide face seal. The face seal is contained within the gearbox and compressed between a gearbox end cap and a shaft bearing, obviating the need for external loading by bellows or similar spring elements.

Abstract: A fully automated land irrigation system to irrigate regular and irregular shapes of land. The system includes an expanse of water delivery pipe moved laterally while irrigating adjacent to a stationary row of spaced access valves supplied by a water main. A swing arm is pivotally mounted to one end of the delivery pipe and a valve coupler is mounted to the opposite free swinging swing arm end. Valve connection is made and the delivery pipe irrigates while traveling to the next successive access valve. The coupler is then disconnected from the valve and the free swing arm end and coupler are ground pivoted to the next valve where connection is again made. Delivery pipe travel results in rotation of the swing arm about the valve connection. This rotation feature also enables the swing arm and the water delivery pipe to the pivoted about a valve as an anchor to a similar position on the opposite side of the water main.
