US Patent 7419107 Swivel inlet hose-drag linear irrigation machine

A swivel inlet hose-drag irrigation machine is disclosed which utilizes an inlet elbow mounted in a swivel bearing on the cart to attach a water supply hose to the machine. The inlet elbow is mounted to the side of the four-wheel linear cart rather than behind the cart between the tires. The inlet elbow is free to rotate in a 180° arc so that the hose can be attached from either end of the cart at the side thereof. The machine also includes a pair of vertically disposed and rotatable rollers which are mounted at the opposite ends of the cart to push the drag hose out of the way of the tires of the cart so that the tires of the cart do not roll over the drag hose thereby eliminating any manual handling of the drag hose.
