Jet Agitation vs. Mechanical Agitation Which is best? Those of you who have sprayers with jet agitation(i.e. Lesco space saver), is the agitation adequate enough to use granule urea and some suspension grade products? What are you experiences with the space saver? I like the size of the space saver, but I don't know if the agitation will be adequate enough. Most of the sprayers with mechanical agitation are much larger than I prefer. I'm not sure what to do!
