Boom/boomless sprayers for acreage

How much bigger you want to go?

I use a 15 gallon sprayer with a boomless nozzle. I cover approximately 0.75-1.0 Gal/1000 sqft for measured applications (e.g. not glyphosate). I’ll likely need something larger once the full yard is established and ready for treatment. But I don’t want to have to use the tractor with a 3pt sprayer, I’d much rather a tow behind with the ATV.

What are you spraying?

From my experience, none of these residential sized sprayer pumps can come anywhere close to providing the pressure that is intended for those boomless nozzles. You can still get the wide spray pattern, but droplets are large and coverage can be inconsistent. This is acceptable for spraying of non-selectives like glyphosate, but I found it lacking for selective herbicides in turf grass. I built a 10’, 7-nozzle, boom sprayer with a 4-gpm pump. However, that flow rate is essentially at no back pressure. Most nozzles want at least 30 psi to perform properly, and the pump’s output is probably closer to 2 gpm at that point. Also, most herbicides should be diluted to 30 gallons of solution per acre. As such, you can’t spray an acre in less than 15 minutes.

For multiple acres, the next step up is a built-in small engine or PTO power.

Which make of tractor sprayer do you have?

Just spraying about 8 acres of grass for weeds and fertilizing. A tractor will do more harm than good in some spots so that’s out. I’m thinking a small gas powered diaphragm pump will be sufficient and making a small boom with some pex and tee jet tips wouldn’t be too bad other than finding the time to build it. I wish there were places around that rented gif course sprayers.
