How many gallons per 1,000 with your spray rig?

I'm trying to get things calibrated so I can get the most done in a day without having to refill my spray tank. When I initially calibrated things, I had it spraying 7.5 gallons per 1,000 sq/ft but as I work the numbers, that just won't do. So I'm now working on getting my nozzle and pressure settings so that I can treat 1,000 sq/ft with about 3 gallons.

I'm curious to know if that's in line with the rest of you, if its a little high or a little low.

At 3 gal/1,000, I can treat 68k with one tank, which comes to roughly 13 properties at an average of 5,000 sq/ft of turf. I think that should put me at about mid-day needing to refill, which works OK. But I'm new to this so I could be way wrong...

Keep in mind your nozzle compliments your calibration. I usually set my gpm to where I want to be utilizing the regulator and calibrate without the nozzle. The nozzle comes into play after I have the flow rate established. With all that set you will have proper atomization of liquid without excessive recoil on the gun or over-spray.

With my skids I try to get them to 1:1 ratio. New guys typically do good at 1.5-2 gal per k.

The most important question is: are you adding fertilizer to your liquid mixture? If yes, you cannot get the solution highly concentrated, as it might burn the grass. Then 3 gals per thousand sqft is about right.

However, if you are not adding urea or other fertilizer--then you can spray a lot less water as carrier for your herbicide. Try to get down to a gallon per thousand sqft. Easy, reduce pressure to about 50; you may need to go with a different nozzle--perhaps a JD-9 spray gun. Or T-Jet.

I am spraying urea, 1/2# per 1,000. I'm using this gun - https://www.gnci.org/mag-i-do-all-kit-assembly - with the yellow nozzle. I can try the blue and see if I can get it adjusted down and still get good coverage.

I think I'm going to play around with it some over the weekend and see how I can dial it in.

How are you liking that gun? Is it as heavy as a JD9?

I don't really have that much experience with it yet, and have never used a JD9, but it seems well built. It isn't super light but it isn't all that heavy either. I think the hose is probably going to get heavy a lot sooner than the gun, no matter which gun it is but like I said, I'm still new to this so we'll see.

i've got a 100 gallon skid and 50 gallon skid. I've got both of them calibrated at 1.5 Gallons per k with the blue lesco spray tips / chemlawn guns. I get about 100k sq. ft. out of a fill. I only spray pre/post emergent and i end up going granular on any fert i have to put down.
