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.
