spent all day getting it tuned up and ready. 1984 versatile , model 580. plus picked up 3000.00 worth of spray for 120 acres, now that is nuts. gonna spray water on a 10 acre hay field just to see if she uses 100 gallons of water , i cant seam to find what my nozzles are rated for. most are 10 gal/ acre nozzles.

Try a sprayer calibration method I have used before. Measure your nozzle spacing, mark out a course to run the sprayer over according to nozzle spacing for 1/128th of an acre (20 inch spacing = 204 feet, 22 inch = 186 feet), fill sprayer about half full with clean water, have sprayer running at the pressure and speed you want when entering your course and exiting the course, record the time it takes to go through the course, do it a couple or three times (go both ways if you can), average the time, park sprayer and run at your rpm,pressure just like in the course and catch the flow from a nozzle in an oz graduated container for the average time it took in the course, read the oz, that's how many gallons/acre you will use.
I did this once for our sprayer and recorded everything in the spray log so anytime I change nozzles all I have to do is the last step and catch the nozzle output for the time so I know how much I'm using an acre.
I have a little card from the extension service with the distances needed for nozzle/row/band widths from 6 inches to 48 inches in 2 inch increments. Paul
 
Thats what I did sprayed a 5 acre parcel to see what its putting on. My boss tried some high dollar calculations well hes just under 8 gallon off
 
well i have 20 nozzle spacing, going to go 5 1/2 mph at 35 psi. so he is off by almost one acre, quite a bit . have 120 acres to spray so that 3 tanks at 400 gallons.
 
i have the grey flat spray nozzles delavan #110-2R . supposed to be color coded , but lot of good that does if they cant tell you if they are 10 gallon / acre or what. make a person waste time checking and checking . so as i said i have a 10 acre hay field and if i use around 100 gallons for that at 5 1/2 mph and 35 psi. from that you can tweek things, faster or slower or more or less pressure.
 
Rustred If you Look at Teejet's web site it will send you to a PDF file Look for your nozzle then move across the chart to the speed and pressure you want. They only post speed and pressure in even MPH and pressure in 10 PSI increments so you will need to adjust some for that. Though if you were to then use the oz per nozzle figure you should be right on the money. Now if you're using old worn nozzles then you will be off. Yes nozzles wear with use just like anything else. I am thinking of going back to flood jet nozzles for easier application with less plugging. I'm also thinking of looking at some of those low drift nozzles for spraying beans to cut spray loss on breezy days. For those going to say don't spray if it is windy sounds good till the middle of the field and half empty and need to finish the tank.
 
35 psi will be about the minimum pressure you can use. On mine I have 20 spacing and use 8003 nozzles, go 5mph at 50psi and get 20 gal/acre. The lower gallons per acre you use the more drift you will get and the more trouble with plugged nozzles you get. Make sure you have the proper screens in each tip as that will help with plugged nozzles.
 
Write down the speed and pressure for each set of nozzles that you have, then you will know next time.
 
No such thing as a 10 GPA spray tip. Spray tips are rated by flow output.
Paul outlined a good method to use for spray calibration. Used that method for over 40 years.
Takes me 25 seconds to drive 204 feet at 5.5 MPH. Collect the output in ounces for that length of time that is how many GPA will be applied.
Works for me for a 20 inch spacing.
 
When I used to spray I had at least four sets of tips of varying sizes and styles anywhere from 40 t0 ten gallons an acre, 10 to 50 psi. Its a guess if you don't know the nozzle number and chart.
 
I use 8002/11002 nozzles. 20 spaceing,30 psi,5mph is almost exactly 10 gpa.My 100 gal tank covers 10 acres. Or close enough.I use the chart put out by TeeJet.Prefect,'spot on'? No. But close enough. I've sprayed enough acres over the years to know that it works.
 

I don't know but it looks like you have a lot of sprayer overlap with that nozzle spacing. Seems to me you adjust the nozzle spacing based on the distance from the nozzle to the top of what ever you are spraying. So it would make a difference if spraying bare ground or 6 inch or 2 feet tall grass. The taller the grass the less number of nozzles needed and the less money spent on chemical. You probably know that and probably not your main concern now but just my observation.
 
(quoted from post at 08:17:51 06/12/21) Spray tips should half lap at the point of contact.
Absolutely nothing to do with the amount of chemical used.

Good to know. Thanks.
 
they are to overlap 50 percent with 20 nozzle height, that is pretty well what i have. i have big wild oat problem and want things set
proper , plus the field is staged so i will catch the most as possible. not so in the end they say you did not spray it properly. plus i even
asked if the 20 is from ground or crop height?? what u guys say? the little field girl said from ground .i also been spraying for lots of
years.
 
20 psi at 4 mph is 20 gallon per acre right on the money every time with my sprayer and the nozzles I have .
