Okay Gang, I'm building a field sprayer. Any advice/suggestions offered will be most appreciated. Here's what I'm working with so far. I have an old military portable air conditioning unit that I stripped down to the bare trailer unit. I've got two 275 gallon tanks that I'm "T"ing together with seperate shut-offs. Plan on a six foot center section and twelve foot booms on that for a total of a thirty foot spray boom. Making the boom adjustable height using a heavy duty scissor jack and a sliding rail set-up. The boom sections will fold forward so I don't have to worry about parking it under a low roof. I'm making a double hinge that will pin lock back and be spring loaded to be able to go back without bending the boom. Using a roller pump at the PTO. Plan to mount a 10-20 gallon fresh water tank on the front for rinsing and so on. That's about it so far. Any other ideas/suggestions? I'm open to any and all! Ron

Sounds like you are off to a good start. I would plumb in a 2" line strainer on the fill line and a 3/4" line strainer on each of the boom feed lines. The clean water tank is a great idea, it will come in handy alot of times especially if it ran dry the last time you used it and you forgot to fill it. If you were to plumb it right you could pull clean water from the clean water tank into the pump and then through a short hose and wand so you could rinse the sprayer tanks in the field, if your close to home all the time it might not be a big deal but I know there have been alot of times I wished I had a self contained rinse system on our sprayer. If you go to Sprayer Specialies site you can get a free catalog from them which will have just about any sprayer part you could ever need as well as several diagrams showing how to plumb a sprayer.

Do a search for Sprayer Systems or Ag-Chem and get their catalogs for layout designs, showing components that are available, nozzle recommendations, etc.

What are the tanks made of?

Is there a reason you want two tanks? They will both need agitation, & you will need to mix your chemicals in each seperately, as often herbicides settle out & will not mix throughout both tanks if you only add to one tank - will be too rich in first tank, too thin in the other tank unless you _really_ engineer that. Seems more complicated than it is worth.

Would help to know what you plant to apply on what tho.

I just bought a used pull-behind for $300. 300 gallons, belt driven cast iron pto pump, 40 foot boom, good poly tank.

My tanks are plastic. I've got a pair of those square plastic chem tanks that have the steel cage around them. I plan to have agitation fed to both tanks via a "T"ed pressure bypass. I can shut each tank off seperately, so I'll add the chem to each tank and then fill each one, or just one if that's all I need at the moment. I'm on a budget and these were within my means. I'll be spraying mostly herbacides. Can't really see a need to be spraying anything else. I looked around the area and the cheapest used sprayer I could find over 200 gallon capacity was going for around $800.00. That's when I decided to build my own. Thanks

Understandable.

Older sprayers got cheap with the threat of soybean rust this year, everyone wants something new & capacity to handle the fungicides.

While your booms are not considered wide, I would add electric solenoids to control the flow to each section of them so that if a field tapers you can keep spraying without much overlap, i.e. shut a section off at a time as needed.

If you can rig a pressure regulator within arms reach you can adjust the flow on the go for various soils, when fertilizing, not applying pesticides.

For some applications I do like to apply liquid fertilizer as you can blend it as to NPK, and add zinc, iron, or other to suit your soil tests or wishes. Not enough soil moisture to apply anhydrous? Apply liquid instead so that no fertilizer dollar is lost.

Depending upon what you will be spraying, use check valve, no drip, nozzles.

I would also have a filter screen on each tip in addition to a pump filter.

Use quick connect hose ends for easy on, easy off.

Just my opinion.

I plan on manual shut offs on each boom. Dollar considerations. I also plan on putting a side pointing nozzle with shut off on the end of each boom for doing fence rows when I start my passes. I'll be doing nothing but 130 acres of hay fields, so I'm trying to build to suit my application. I rented a 300 gallon sprayer this Spring and had to make a lot of refill trips. Trying to cut that down with more capacity. And to everyone, thanks for your replies and suggestions. More is welcome. Make me think this out! Ron

What are your tanks made of? Plastic? Steel? Stainless steel?

Glyphosate (Round-Up) is very corrosive. So is most fungasides, and fertilizers. Steel might be a no-no...

2,4-D will "bond" with some plastics, including fiberglass resin.

Stainless is probably the prefered material, with plastic being #2.

Ron, don't know what..... ...or how much..... ...you're spraying, and if you have your heart set on building your own, I don't have anything to add; BUT..... ..locally (West TN) old tricycle Spray Coupes (220 or something similar) in usuable condition can often be found at auction for around $1000-1500. I realize it's another piece of equipment to keep up, but anyone who's ever owned one would never go back to a pull-behind unit. Booms are electric or hydraulic raise and fold and are usually 51 - 60 ft in width.
