Thanks Bob, I knew it was a little more complicated than just turning down the regulator...
So what you're saying is lower pressure= more narrow width...It's up to the operator to calibrate themselves. No reduction in groundspeed necessary?? just run the same ground speed with less distance between passes so correct overlap is achieved?
