White Gardens: yes, i do. good idea.
I have one more question, on my sprayer (pic above) i wanted to be able to run it with the boom folded for use in tight areas, so put a valve before the nozzles on each outer piece of the boom, Works great.
The question is if i need to adjust rates to run it like that? the pressure obviously changes, so if i run it at the same pressure as i do with the boom un-folded, does the app rate need to change too?
