LureMaker, I started out years ago with a single nozzle pasture sprayer and knew so little that I didn't know the nozzle was partly missing till I couldn't figure out why it sprayed a powerful thin stream straight back 150 feet!
Got the rest hooked up and it worked OK (but wind drift is a BIG consideration.) So... I went to a popular mfg outfit in OKC and bought an add on boom accessory. It has three sections. One is fixed in position in the center the unit as wide as the sprayer. the other two are articulated spring loaded arms with flexible joints at an angle. If one of the movable arms touches the ground or some brush it swings back and up and returns to positioin via gravity. The spring detent tends to keep it in the normal position unless you hit something.
I have it plumbed so I can use the single original nozzle, or the boom sprayer. I added some ball valves so I can spray left, center, or right independently or in any combination or even booms and center nozzle if you want. For traveling and not spraying the outer booms swing back and up and touch where you can tie them together. I welded square tubing to the original frame and to the booms. The boom attachment can be dismounted from the sprayer frame like disconnecting two small receiver hitches (the square tube on the booms is a telescopic size smaller than what I put on the frame.)
If you don't have a wind problem you may never need a boom. I find the boom allows getting the spray down where you want it with minimum drift and gives a much more uniform distribution of chemical. The single nozzle gives very spotty coverage, double or tripple dose on some areas and no dose on some areas when there are winds of variable direction. Another plus, even though I have a cab on my Kubota, is that the boom while delivering its chemical closer to the ground with less wind drift, doesn't put as much spray on the tractor and the operator.
You might make a couple passes, carefully turning so as to not get the tractor AND YOUR EYES, SKIN, AND LUNGS in the chemical plume and then the wind shifts or you drive into an eddy... I'm thinking of adding adding a 12 volt solelnoid valve to kill the spray from inside the tractor. You don't have time to reach for manual levers on the sprayer. Unfortunately with the single nozzle sprayer there is a lot of mist fairly high in the air and even if you turn the sprayer off a flaw in the wind can get you and the tractor well covered with chemical.
