Rain TrainTraveling Sprinkler With a rustproof cast iron construction, the sprinkler waters up to 13,500 square feet, though covering a lesser area of 11,900 square feet ensures more effective performance. The sprinkler arms adjust for varied spray patterns and arcs, throwing water from 15 to 56 feet. The sprinkler waters as it travels along a hose on a preset route, much like an electric model train, except with a hose as the rails. To water, the homeowner lays out the hose as desired, taking care to avoid dramatic corners or turnabouts that may result in hose kinks or a derailed sprinkler. A front wheel runs on the hose with the two traction-ready rear wheels bestride. The hose connects to the posterior of the sprinkler. For the best results, LR Nelson recommends a 5/8-inch hose, though a 1/2-inch hose may suffice, up to 200 feet in length. For sprinkling termination, the user places a shut-off ramp on the hose to lift the sprinkler off its "rails," while simultaneous stopping operation. The shut-off ramp should be installed with at least five feet of hose between it and the spigot. The traveling sprinkler operates at two motor speeds, high and low. On high power, the sprinkler travels approximately 37 feet per hour, with a 1/4-inch water application. On low power, the sprinkler moves at a 21 feet per hour rate with a 1/2-inch water application. The simple installation requires no tools. The sprinkler weighs 18 poundsBrand new
