Many threads on sprayers I've browsed through. Seems that a 6 roller cast iron pump with 55 gal tank is popular version from TSC. If my calculations are right, 55 gal would adequately treat about 1.3 acres with round-up or it's generic version . If I went to 100 gal, what kind of weight am I carrying on the 3-pt?? I'm also a bit nervous about cast iron pump, given the negative comments I've read. What's a better alternative??

well, weight of sprayer will vary a bit from mfg to mfg but water weighs about 8.5 per gallon so roughly 850 there. I think my sprayer frame and pump weighs about 250 pounds. Don't know what the weight of the Round-up will add to that but I bet it would be negligble.

a gallon is roughly 8 pounds,unless you are talking honey, so roughly 800 pounds for 100 gallons. Remember, some folks think the iron pump is easily corroded by glyphosphate and go with plastic. Hope that helped.

1000 -> 1200 Lbs depending on dry weight of the sprayer.
I've got both, a 55 gal boomless sprayer and a 110 gal with a boom. I use the small sprayer to do horse paddocks (100' X 250') and root feeding for my trees with an attachment and the 110 gal boom sprayer in my hay fields.
Both have a similar Hypro 6500 roller pumps. The big one weighs about 1000# when full. I replaced the pump on the smaller unit when a neighbor broke it with a SilverCast Hypro, so it'll probably outlast me. I mostly spray 2,4,D, Liquid Lime, and liquid fertilizer and rinse out with a commercial rinse agent. I've been doing this for years and haven't worn out a pump yet.

Rather than increase the size and weight of your tank, if that worries you, why not adjust your application rate? We spray remote sites without water readily available, and have very good luck with glyphosate (RoundUp) applied using much less water than the 42.3 g/acre you're calculating. Glyphosate, 2,4 D, Plateau, etc. will apply well in half the water you've specified.
I'm using a 135 gallon tank and a 21 foot boom on the 3-point hitch on a JD 5220. On the rough fields we're spraying, I know I wouldn't want that weight on a lightweight tractor. I also use a Kubota L3400, and would not want the full weight of that spray rig on it at the speed I'm traveling considering the rocky, bumpy terrain.

I calabrate my sprayer to 10gal per acre (water) when spraying glyphosate or 2,4-D. 42.3 is a LOT.
The local chemical supplier who has studied application rates professionally made the suggestion of using 1 oz/gal water/1000 sq feet treated, based on his computer spreadsheet. I guess it works well at higher concentrations as you guys suggest. I don't think my 12v ATV sprayer would work well with more concentrated solution, but 3-pt pump is apparently capable of spraying more viscous liquids. Thanks for the input.
Let me see about your rate; a gallon of water per 1000 sqft = 43.56 GPA (gallons per acre) The label recommends 3-40 gpa but if you are spraying dense woody brush (starting food plots?) 43.56 gpa would work, but it's high. Now to your rate of 1 oz/1000 sqft = 43.56 oz/acre (or 1.36 Qt/Acre). At first, I thought it was going to be a high rate of roundup, but after looking at the label, it's on the low to med. rate, which is fine.
A 12v ATV sprayer can be calibrated for whatever GPA, it's a matter of speed and the pressure the pump can do. I used my 12v pump last week for my road, I have it set at 8 GPA (because the weeds are small & not dense) I fill it to 9 gallons and I use 90 oz. (or about 2.5 Qts./acre), maybe more or less since I'm not sure if I'm actually hitting my 3 mph mark. So, I'm putting out almost twice the rate with less water.
I can make my sprayer put out 40 GPA but I would have to drive very slowly, refill 3 times, and use around 20 oz of Roundup (another guess) in each tank. In the end it would do about the same (sort of - I think it would wash off with that much water). That would work if I wanted to kill the thick pasture.
To give you a better reply, you need to answer these questions:
What are you trying to kill?
How much area do you need to spray?
Do you know what your ATV sprayer puts out? (gallons per acre)
A 100 gallon sprayer is not going to help much if you only need 10 gallons at a time (or a 55 gal. sprayer if you need to do 50 acres).

Generally, I'm going to be spraying up to 2 acres at a time. Mostly weeds that grew in food plots since last year. I bought a 26 gal ATV boomless unit from northern tool 2 years ago. Not sure if pump ever worked right. No problem with pure water. RU mix, even as dilute as I'm mixing it does not spray nearly as far or as uniformly as water. Thought a 3-pt unit would be better for larger tank and more concentrated liquid.

The nozzles may be part of the problem on your 12V sprayer. Check the size.
Did you get something like this?
NorthStar ATV Sprayer with Boom-less Spray System — 26 Gallon, 4 GPM, 12 Volt |ATV Sprayers | Northern Tool + Equipment
"broadcast spreader" and "Boomless"? I'm guessing "flood" nozzles but that still doesn't explain Roundup mix not spraying correctly?? All the Roundup that I've used is just a little thicker than water and you can just barely tell that it's in the tank after it's mixed up... How old is the Roundup?
I would remove the nozzles and look at the screens below the nozzle (it should be there, clean them). I would run the sprayer with clean water and no nozzles in, just to make sure the hoses are clean. You can modify what you have into a boom sprayer with "Flat Fan" nozzles like this:
ASC # 58894
That can be mounted on a modified Carry-all for a whole lot less money. I'll try and remember to post photos of my sprayer tonight.

The ATV sprayer nozzles and uptake are clear. Beautiful 25-30 ' pattern of coverage with pure water. Add recommended amount of RU liquid, mix thoroughly, and voila, pitiful spray pattern results. I never tested the flow through the system with nozzles off after RU mixed in. That would surely point either to the pump or the nozzles. I replaced the pump over the winter and it works great with pure water. Still waiting for weeds to start actively growing to try the real test. I'll report back in about a month.
Wow, 25-30' pattern!!! Like to see a photo of that! Speaking of which, here's mine. pieces, parts and basically a frankenstein contraption... but the price was right. I have to give up, I do NOT know what else might be the problem. Let us know in a month...

One thing to keep in mind, the ammount of "carrier" (water) used to spray different products depends on (A) the product to be sprayed. (B) the type of spray nozzles you're using. (C) conditions under which you're spraying.
Fungasides need more water per oz. of product to deliver correctly. (Needs to be well atomized) More water requires higher pressure to spray nozzles. Higher pressure will cause more atomization which contributes to spray drift. You can't (shouldn't) spray glyphosate at the same delivery rate as a fungaside.
Get a "user guide" from Tee-Jet. That'll tell you average pressures, average delivery rates, and recommended nozzles for any application.
There is no "across the board" single answer to spraying all products at the same pressure or dilution rates.

My usage would be primarily RU application to control weeds for food plots. Don't see any insectacide or fungicide applications. If the boomless type can give reasonably good coverage, that would be my preference. Not so worried about wind drift, since I can adjust my path to be into the wind easily, given the orientation of my fields.

Round-Up is applied best at low rates of water. (10 gal per acre works splendidly) Higher dilution rates will adversly effect it's performance.
Again, I'd HIGHLY recommend getting the "user guide" from Tee-Jet. It will take you step-by-step through industry standards for spray application.

Add a spreader sticker to your solution and you will get better control from the herbicide. The iron roller pump will be fine if you clean it after each use.

I used to use a small ammount of diesel fuel as a spray surfactant. Now there's commercially available "over-the-counter" surfactants that are more environmentally friendly. (And maybe cheaper than diesel fuel too
)
