looking for wisdom

[waugh621]

I am wanting to build a sprayer that mounts to a farmall 560. so my question to those who know is what are the lessons that others have learned either built or used a home built sprayer. Also what are the opinions on....
1. i am only planning on making the booms 10' on either side of the tractor. Would PVC reinforced with some angle iron hold up to field abuse/ chem
2. is a PTO or hydraulic water pump better
3. what is the spacing between nozzles the internet has a few different spacing
I will post a drawing of what i want after i get done designing it.
Thanks Nate

Personally I wouldnt want the same pipe used for liquid and structure. Most booms are made using iron pipe or angle. Various spray jet adapters are available to mount to pipe or angle iron. Then run hose between them. The nozzle guides are a bit intimidating at first but once you get what they are saying it's pretty easy to figure out the nozzle/ GPM/ MPH/ GPA relationship. There are nozzle/ GPA calculators on line, I have one on my phone

I have never been accused of being an artist but here is a very rough idea of what i am thinking

Forgot to add that how you run the pump is a bit dependant on the tractor. Most older smaller tractors won't have the hydraulic capacity to run a pump. PTO is cheaper/better I think? Your plumbing diagram looks OK to me. Yes you need a regulator which goes where you have a valve in the drawing. Your bypass return hose should go back in the bottom of the tank to avoid foaming and it helps keep things stirred up. Sprayer booms get beat around pretty good, I don't think OVC hung out that far is going to cut it unless on very smooth ground

I think my boom diagram is a little misleading. The PCV will be held up an tied to a 6ft peice of angle iron horizontal to the tractor.

First the barrel is going to be a rust problem especially after the first year. Then you need a strainer in the line from the pump to the booms with a branch off that line to the barrel or tank to work for agitation. I like a sparging line for agitation since it will sweep the bottom of the tank for the length of it if set right. You will also need a valve on the agitation to adjust your spray pressure at the booms or else you will need to use some other means for pressure control. Nozzle spacing depends on the nozzles. IF going with flat fans most are set at 20 inch apart if using flood jets then you can go farther apart with them and this will all depend again on the angle of the nozzles. 80 degrees on fans is 20 inches 110 degree would be able to be a bit farther apart. Then what speed and pressure do you want to use. Sprayers are money pits in a way since you can spend as much as you want to on them. Getting flow meters and electric shutoffs for the booms and so on I have 3 strainers in mine one on the main line back then one for each boom . I would like to add another for the 3rd section behind in the middle when I put the extra shutoff in for it. For a pump I would look for one of the Ace pumps PTO driven with your tractor. Open center hydraulic systems don't like hydraulic driven motors so well they get hot if not sized right for the flow and then you can get into other problems with them. Like on our 674 the hydraulic pump is only 12GPM with 3 GPm for the steering brakes and trans lube so now only 9GPM to run the pump with and if you try to steer with the sprayer on and setting still it is a feat to do it. While driving you don't notice it so much. Yes I'm running a hydraulic pump on an 806 with a separate pump for the other jobs steering brakes trans lube and so on. Works but again it gets warm on hot days. I want to change it over to a PTO driven pump. Roller pumps would do what you want for volume but will lack for it doing the agitation and boom pressure and volume with one pump even the 8 roller one are short. We used to 50 years ago use 2 roller pumps with a belt to run the second one . One for the booms and one for just the agitation . If you can get a stainless tank it would be best in the long run for cleanliness and ease of use since they don't deteriorate over time in the sun like poly does and don't rust like steel will. I like Stainless for those reasons and use stainless fittings on a lot of the plumbing. It works better with fewer leaks. A pine 2x4 would work for your boom with not anymore weight than the pvc and an angle iron on it. With the 2x4 you could fasten your hinge nozzles and support all to the wood and be fine. We had that 50 years ago with 2 barrels then an oil tank for a furnace on it. All had rust problems. WE even had a piece of galvanized pipe for the boom water with nozzles taped into the pipe worked but again rust and dirt. With the wood you could just get the amount of hose for the boom nozzles and cut it for each nozzle and connect together as you go down the boom with your nozzles. Depending on your planter size I would either try to fit the planter size or go 3 times the size so I would drive in the tractor tracks since the guess rows may be off some and not fit the tractor track. I have that problem with 40foot of planter and 60foot of booms I get into a guess row occasionally so I have to crowd close then or risk a skip in the coverage.

No. That 4' of 3/4" PVC will whip around and snap off at the end of you angle after not too long.

Yes. You need a regulator.

If you're buying all the bits and pieces new it might not be that much more to buy a complete sprayer ready to go.

Buy an old unit and fix as necessary. If you buy all new materials it will cost more than buying a used and modified. Around here you can get 50-90 ft older sprayer for under $500. You have all you need and extra nozzles to boot.

Where are you located? I have been looking for sprayers for a few months and the only ones under 500 bucks are junk. I am not apposed to a road trip for the right price

Just go on Craigslist. Lots of those old 300 gallon trailer sprayers setting around here in Mn.

I have been doing some looking over the last few days and have put this list together at farmchem. If someone wouldn't mind looking it over and telling me if i am missing anything would be a great help. Also after reading the suggestions on this post i will be going with the wooden booms, that being said what kind of hose should i use.
Thanks Nate

Edit i know i will need more fitting and plumbing on the pump but i will get that from my local hardware. I think this should get my booms made. 26' total at 20" spacing
