I have a 300 gallon tank that ive never used before.. Started looking into getting a field sprayer and saw a few people have made theirs.. I was thinking of using this tank and a 30 ft boomless nozzle to make one onto my trailer.. Looking to see if anyone had done this or similar ideas.. Thanks

You’ve got the trailer and have picked out your nozzle....all you need is a tractor, an 8 roller pump, some non collapsible hose (tank to pump), line hose to pressure relief valve (bypass valve)where it will split with one line to nozzle and the other back to the tank, put a pressure gauge (glycol filled) inline to the nozzle where you can see it from the tractor seat. Also put in a filter. May be some question as to where, but I have mine behind any and all non plastic fittings. Also a good idea to put in some good quality cutoff valves on the tank hoses should you need to shut them off when you blow a line or pull a hose off.....
We bought the tank and trailer used and rigged up the rest.

Also note that recycle/recirc line would typically come from the pressure regulator that controls pressure on the line(s) to the nozzles. Nozzle pressure controlled by bleeding excess back to the tank instead of an inline pressure regulator. Think constant flow from the pump, nozzle flow rate controlled by the pressure you set, rest of flow recirculates to tank. Install a jet agitator in the bottom of the tank and connect the recirc line to the jet agitator.
Jet agitator like this has a venturi that uses the recirc flow to pull in internal tank contents and mix with the recirc flow - keeping the mix agitated. Especially important if you spray wetable powders or leave the tank mix setting for several hours.
Use a large enough pump to allow enough recirc to keep the tank mixed.
Think of it more as a manual pressure relief than a regulator.
If your pump will put up #50 against your nozzle but you only need #30 you crack the manual choke and bring the pressure down to #30. The excess is put back in to the tank which also agitates it. That is how ours is set up at least. May be different ways of doing it.
Guess a diesel fuel system is similar. The excess diesel from the injector pump gets circulated back in to the fuel tank... I think.

Yes, 4 gallons per minute. Many told me it was a mistake, to use a roller pump. I wanted to be able to pull it with an AtV or side by side. You lose track of time, but that pump is a few years old, and been over more than 1000 acres. Ive got a regulator, and can return half the flow to the tank. If I ever build another one, I will skip both. I just run it wide open, and it puts out 20 gallons per acre. That works for everything I spray. I built it in the parking lot of the spray place. Didn't take long.

What brand of pump did you use? I have a small 30 gallon tank on my utv that I use for spot spraying, but I have used a boomless nozzle to spray som hard to get to spots. Mine just does not seem to really do the 4 gallons a minute.

Can't argue with success. It works and is simple. Does it look like it produces steady flow/pressure at the nozzle? I have a TSC 30 gallon that I use to spray my yard at the house. It looks like it has pulsating flow at the nozzle. Just has a small Finco pump.Bigfoot said:sstterry said:Bigfoot said:I made this one:

Do you have a vent in the fill cap?
You can also hook a Honda or B&S gas motor to a roller pump and mount it on the trailer.
You need to have a pressure regulating device....however that function is performed, so that you can control your droplet size and reduce the opportunity for drift. As I tagged earlier, my wire, serviceable filter is in a plastic assembly with a hand operated screw valve which regulates the flow volume to the spray head and in doing so regulates the pressure of the output. I usually run </= 30 psig off a PTO gear pump.
I don't know if it was covered, but you need a shut off valve and a disconnect in the line from the tank to the pump such that you can hold the mix in the tank when transporting...no dribbles, and when it's time to clean out the tank and have it drained for non use periods, it's an easy process.....I think so anyway. :clap:

Here's mine. Uses a one inch trash pump. Intake is through the bottom and filtered.
I could put it on a trailer ,but I built it to put on the back of a truck and that's generally how I use it.

Mine was an old, rubber tired, drag type, fiberglass, PTO gear pump, boom sprayer I bought from a farmer's junk yard. Cut the booms off and added the single head, chopped the legs since it was high enough to spray cotton for Bowl Weevils.
