Anyone running a case patriot or new holland sprayer with aim command or intellispray? Im looking at buying a NH unit with this option. We spray a lot of powder fungicide at a high rate (1kg/ac) but also use a high rate of water, 25-30 g/ac. I have been told some people have experienced problems with the solenoids and plungers getting stuck open due to the powders. Anyone found this or have experience with this?
