3 Pt Sprayer Size Questions

Me and the boys rebuilt a 50 gallon sprayer and have successfully used it over this summer - all good.

However....

50 gallons don't go very far and so the re-fill trips are somewhat frequent for 12ish acres. Not extreme, but more than I'd like.

Thinking about buying a larger tank sprayer or re-working this sprayer frame to take a larger tank. The boom is 20 ft - which is perfect for our smaller irregular shaped fields. What I need is more time out in the field spraying (say after work where daylight and time is limited) and less time coming in for a re-fill.

What size tank do you recommend for a 3 pt sprayer? Using the JD 5055d with cat II rear lift, the MF50 is cat I. I prefer 3 pt just because it's easier to get around vs pull type.

Any advice/recommendations are much appreciated.

Thanks!

I have a 3 pt sprayer that I use on a CIH 695. It will handle 150 gallons without front weights added. After that we need to either leave the loader on or hang on weights. My sprayer has a 300 gallon tank, but I don't fill more than 250, that is 2000 lbs. What is the lift capacity of your 3 pt hitch?
 
We have a 60 gallon tank that is used to spray our fields.

We use a 200 gallon tank on a two-wheel buggy to transport additional water.

The <a href="https://youtu.be/pXC4OYtMVV8">water is pumped from the "water buggy"</a> to the sprayer.

We will be using both of the tractors above to spray the hay meadow tomorrow.

Hope this helps.
 
Can you put smaller nozzles and lower the pressure to cover more ground per tank? You will of course have to recalibtate your mixture upward.
 
I thought about this, but when applying 2,4-D or other herbicides, I'm to understand that you want more of a fine droplet than a mist or vapor that can drift.

What is a reasonable/typical gallons per minute of total liquid one would spray - knowing that whatever amount of herbicide is mixed in would be appropriate for that flow rate? 1 gal/min, 2 gal/min, etc.?

Thanks,
Bill
 
Used to be 5 gal per acre tips and 40 pounds pressure for 2 4 D so you should be able to get 10 acres out of a drum. I do not know if they have increased the water rate per acre recemondings or not. We never for anything used bigger than 10 gal tips and at the 40 pounds pressure so you should still get 5 acres per tank. It has been years since done any spraying as don't farm any more. I think the first sprayer we had (and I still have it) (it was demenstrated on a Ford 8N during the machinery parade around the race track at the local fair where Dad bought it) you could only get 2.5 and 5 gal tips for and we used it that way for years.
 
Thinging about it we never used over 30 pounds pressure and for some spraying applications pressure rate was supposed to be about 25# and make sure you have a relief valve and gauge designed for 60# pressure and not a hundred like they want to push as with those you cannot set your pressure as should be. Over the years I have junked many of thoe higher pressure setups for the 60# ones. You only want that high if you are using tips designed for a spacing of every 4' and not the 20" as you should be using.
 
I have a 110 gallon sprayer with 20 foot boom, nice for little cleanups. My little loader tractor 1720 NH handles it fine, as does the old Ford 960.

If put on a cat 2 size tractor like the Ford 5200 or 7700, I sure wish it was 150 gallon, could still use it on the little tractors just not fill it full.

If I were using it only on the cat 2 tractors, I'd want 200-300 gallon, but then it would not work well on the little fellas at all as I suspect everything would be a little beefier and heavier and wouldn't get many gallon in the heavier rig.

I think 250 gallon would be a good size for me.

Giving some thought to buying a tank and making my own. It might be easier to mount the tank to a trailer chassis and move my booms/hardware off my 3 pt sprayer to it.

Thanks,
Bill
