Little side note: You will see me with a 12 volt pump in the near future. It will be on a 25 gallon tank that mounts on my Hustler X-One with a nice boom attached to it. I believe an application is more accurate with a boom than it is with a hand gun. I also believe 12 volt pumps are great. I just don't think they're as capable as my gas engine setup when it comes to 300' of 1/2" hose at 1.5-2gpm and also maintaining agitation in a 50 gallon tank. This is my opinion though. You probably have twice the knowledge I do if you're spraying 25 lawns a day, because my spraying business is no where near that big nor has it ever been.
