Yesterday I blew snow with my Hago gun for 12 hours. I made 12 inches of snow over a very big area. The wind took lots of the snow that would have made the pile much much bigger and blew it behind the gun. I had over 3 inches behind the gun. I also blew a small amount on my rail and then stopped because we started getting natural snow. I am using a 1/16 inch hose barb that is cut so it is about 1/4 inch from the Hago to prevent all freeze ups. I am also putting 120 psi through it. The two Hago nozzles I normally use now are the 3.50 GPH, 45 degree, semi hollow and the 3.00 GPM, 30 degree, semi hollow. After testing them I think that the 3.00 makes more snow and large range of qualitys. The stuff right by the gun is very hard packed and kind of wet the stuff far from it is lighter packed and super dry, the stuff in between is hard packed and pretty dry. If only I had a bigger water pump. Then I could pump out much more snow than I am now. The pressure washer I have now is a 1.6 GPM at 1300 psi. Nice job on your sue15b. Looks like your putting down a ton of snow!
