With severe drought crippling a significant portion of the U.S. this summer, lawn irrigation is an art every Toolmonger with a yard has considered. While I don’t have an in-ground irrigation system, I’ve been somewhat successful using a few Nelson’s Raintrain traveling sprinklers. They can cover a significant portion of the average yard in the limited hours available for best watering, saving money and allowing you a full night’s sleep. However, just like any car or household machinery, these suburban practice farm machines sometimes break. Fortunately, with an online part order and a little time, they can be brought back to life to water again another day.
