How do you want your last tip setup on your booms? For example on 36" rows, tips 18-20" apart, 8003 tip. Do you run that same tip on the end? Where do you have your last tip placed? Over row? Over middle? What about overlap?
Say I'm throwing together a small 3pt sprayer. 8 row. Would my last tip be over rows 1 & 8 or the middles outside of rows 1 & 8?
