I bought one of these when menards had it on sale sale. I think i paid $349 before rebate for it a few years back.

I've used it for spraying herbicide to try and rid my yard of a neighboring clover invasion, and it's been pretty successful. Need to do the math on the forward speed vs the gallons sprayed... I was spraying 2-4-D.

 

I have a 55 gallon AG Spray. Works great, no problems at all.

I have the 200 gallon version and really like it.

 

HARDI INTERNATIONAL A/S - BNL (hardi-us.com)

Probably one of the nicest sprayers on the market. Deere makes a decent one as well.

 

Yeah, a 2520 ain't gonna pick up a full 200 gallon sprayer.

In the past, i've used a 3 pt carry all, with one of the 275 gallon totes on it for watering around my property. About 125-140 gallons is all it wants without making the front light (with the loader on). You could definitely go bigger than 40 gallon, but the tractor couldn't physically pick up a full 200 gallon unit, despite it pointing at the sky.

I am switching over to a 200 gallon molded tank for watering that'll be closer to the tractor, and hoping to get maybe 150-175 gallons in that one with the lever arm being much less. I'd say anything 100 or less would be good-ish, but 100 full may be interesting, especially if you're looking for a PTO driven sprayer... again, the one I posted is 12v with roughly a 3 gallon/min pump.

 

I guess I need to make this clearer. I as in me has the 200 gallon VERSION. If you look at the link it clearly states 50 - 200 gallons. I’m stating I like mine and provided the link so op could research. He also posted he is interested in pto pump.

 

This is the one I use. Have had it for about 6-7 years now and use with my 2016 Gen1 2032R which is comparable to your 2520.

60 gallon Fimco boomless pto sprayer

Best pricing here.

Fimco Boomless sprayer

 

TSC gallon version of the 40 gallon Fimco boom sprayer for me. Around $300 during one of their sales. Good service for the past 7 years. Used mainly for GrazeOn Next herbicide. I also like the wand attachment that comes with it. It has really good range and concentrated spray pattern so I can drive down a fence line and spot spray on the other side, as well as driving the perimeter of my horse riding arena and hitting those volunteer weeds that come up every spring. Also those spots between trees and the fence with no access for the 10 foot boom .

The TSC looks identical to the one pictured in post #2 by @WarmPepsi.
