Made a visit to our local Ewing outlet yesterday to speak with an old buddy who is the outside consultant for that branch. Him and I go back a ways through him working with different companies prior to Ewing. I asked him what he knew about the MP-Rotator side/corner strips because I'm interested in experimenting with them. He said that he recently returned from the company manufacturing site in Walla Walla, WA and they performed a demonstration to readily show the distribution of the water. They set up an above ground system on concrete and turned it on. Before long one could see a distinctive rectangle watering pattern showing up on the concrete. He said it was way cool to watch. I also asked about the 4000 model and he said it is supposed to ship to distributors at any time. He checked the Ewing company-wide computer system to see if any branches had received them yet but they're still "in process" and haven't hit the shelves yet. I also found out that the "T" as in 2000T stands for Toro since they are one of the few major manufacturers that use male threaded nozzles on their spray pop-ups. Most manufacturers use a female threaded nozzle. I also copped a free Ewing MP Rotator baseball style cap.
