For those using 3 pt sprayers ... PTO or electric?

[Rmart30]

We are looking to get a 3 pt sprayer for hunting plots. Something in the 100-200 gal size.With a 12-18 ft folding boom. What are yalls preferences for a pto or a electric sprayer? This will probably get about 2 tankfuls a year run thru it.

Hypro roller pump. I'm curious what you grow in hunting plots that require spraying.

100 gal Wylie boomless with pto roller pump....however I spray 40 acres with different herbicides.

You don't need the boom. I don't know who makes it but I have a brass nozzle that mounts vertical and sprays about a 25' path at about 20 psi; low pressure for large droplets that don't drift if the wind is low. If you only want to spray in one direction, remove the 2 screws on the top and flip it over with the selected side pointing the way you want to spray. Much better than booms as you have no nozzles or booms to fool with and no booms to break or smash into things and knock your nozzles off.....how do you think I know that???????

SWI,,,,,,,spraying while intoxicated?:laughing:

Growing everything under the sun, thats why we need to spray ........ we will be spraying lots of gly to get rid of it about 6 weeks before putting in fall plots. After 6 weeks most of the stuff is dry and brittle, and the roots are dead and not holding onto the soil like green roots do. We can burn the dead stuff on top and the dried up roots are easier to turn.
It saves us from bush hogging before disking.

....Something in the 100-200 gal size...

I've used both, electric is easier to maintain... Roller pumps with RoundUp need to be cleaned very well or you'll be buying another pump for the next year... Corrosion will kill the pump.

Seems like a big tank for only being used twice, how many acres are you planning to be spraying and how many gallons per acre are you planning to apply?

I would look for a smaller sprayer and re-fill it more times. If spraying more than a few acres, the roller pump is the way to go.

Agreed, but it helps to get a pump that's compatible with what's being sprayed...

3 Steps for Pump Selection:

1.) Determine your highest spraying pressure (psi).

For spray guns, 40 psi is often typical at the nozzle, but to properly select a pump that can deliver the right spray pressure, you should calculate it yourself. Keep in mind that pressure losses are normal and should be factored into the equation. It's recommended that you add 120 psi for system pressure losses.

Desired Pressure at Nozzle (psi)
+ Hose Pressure Loss (psi)
Total Pump Pressure Needed (psi)

2.) Calculate the total pump flow (gpm) using the formula below.

Now you'll need to know the boom flow and agitation for that calculation. You can determine your boom flow (gpm) by multiplying the gpm per nozzle by the number of nozzles. The flow required for agitation is a little easier as that is determined by tank size. For a 500-gallon tank you're looking at 25gpm, 750-gallon tank will be 37 gpm, 1,000-gallon tank at 50 gpm and 1,500-gallon tank at 75 gpm.

Boom Flow (gpm)
+ Agitation (gpm)
Total Pump Flow (gpm)

3. Choose the Hypro... pump based on the manufacturer's catalog performance charts.
Sounds simple, but in addition to the numbers you just crunched you'll also want to keep chemical compatibility in mind. Specific seal, roller and casting materials can be selected for compatibility with certain herbicides, pesticides, fungicides and fertilizers. The three housing material options Cast Iron such as the Delavan line, Ni-Resist or Hypro's Silver Series XL roller pumps are particularly important for total pump life. Studies have shown, especially with weed control chemicals such as Roundup that the Silver Series XL line is more durable and affords a 10x longer pump life.

Right now we will be trying this first on a 1000 acre piece with about 15 miles of roads and trails to see how it does as a test site to get a baseline and establish how much cost/ time savings it would bring. If it works well and we can see a savings on it we could be using it on another 7000 acres and 80 miles of roads and trails.


No water on the property is one reason we have been looking at a larger tank. The fields are also spread far apart and range from 1/3 acre to to 1 acres. Avg size being 1/2 acre.
We have some 25 gal ATV sprayers we use now but constantly refilling. Have to have 2 people driving 2 trucks and trailers. One hauling the sprayer rig, and the other with a tank to keep the water supplied. The truck sits in a central location for the ATV's to come back too so theres a lot of wasted travel and time going back and forth refilling.
Were wanting to get it where one person could go jump on a tractor and handle it by themselves.

It works out to about 18 gallons per acre with 3-4 oz of poison per gallon. On this section its about 15 acres of fields. Done once in spring and then again mid august.
We also would be spot spraying about 20 miles of roads and trails on that section also.

Well, that's a "horse of a different color..." Definitely, PTO pump...

...It works out to about 18 gallons per acre with 3-4 oz of poison per gallon.

So that's a rate of 54oz to 72 oz of RoundUp (Gly) per acre. Pretty hot but I guess you are spraying tall weeds... I mow first and use 32 oz/ Acre and I'm happy with the results.
