I don’t think you were cut out to be a lawyer. I’ve never met one with a lick of basic engineering chops- you know, real world problem solving skills.
Genius!

You make me blush…
My career aptitude test during first year college said… “farmer” & “police or military officer” as the top choices.
Living in NY City , farmer was a little out of reach. Police/Military officer in the 60’s… not so much.

Hi Mike,
What I am trying to achieve is being able to spray quicker with better coverage than the 40 psi electric backpack that I am using now. I do not like putting a sprayer on my back. I lug the one I have now. I do not think the range/pressure is the best on the sprayer I am using.
I will be spraying Surround next year for the first time so the sprayer has to be able to handle Surround. I have two places to spray 30 to 40 trees at my home and another 20 to 25 trees on a farm about two miles away. Only 4 or 5 of the trees at my home have any size - the rest are younger trees or smaller trees due to the poor soil. Refilling a tank is not a big issue for me so smaller works. I have found two electric 4 to 5 gallon sprayers that come with carts that can be pushed with 60PSI or better pressure, but the carts do not look like they were made to be pushed over rough ground. I have looked at sprayers on trailers which I could use with the garden tractor at my house. Thought about taking an ATV strap on sprayer and building my own cart. .
If the Northstar does not handle powder well, that is a definite point against it. If you can’t tell I am all over the place as to what I want. Do any of the homeowner/small orchard type sprayers handle powders/Surround well?
I have a 5 gal cart sprayer - you pull it, not push it. I like it a lot, I can do all the trees in like 1/10 the time it used to take me with a pump-up backpack.
But I can’t attest to its use with Surround
What brand of sprayer?
Master Mfg - from Northern Tool
I don’t use Surround, but the biggest problem I have is the oils in EC formulations and the sticker/spreaders eating the valves and diaphrams in the pump. Fimco is the worst. I have one of their gold series pumps on a 60 gal sprayer and have to rebuild the pump every couple years. Piece of junk.
I finally ordered a pump with all Viton seals and diaphrams about a week ago to replace the Fimco.

What you need to find is a type of pump that can handle the grit of surround. I don’t know if either the diaphragm or the piston pumps available to us can handle that .
Now I am about to get in the weeds…
Look for a sprayer that has a “roller” pump. These pump volume and at pressure See below
If you are handy… just mate it to an electric motor and all you need is some plumbing and spray gun.

Mike,
That looks interesting but I am not sure I have the aptitude to make that type of sprayer pump work. What type of electric engine would work with the shaft on this pump?
What I am thinking about doing is taking the 10 gallon NorthStar Sprayer and rebuilding it with a better pump. This link shows the pumps -

Not sure which pump would be best - is bigger (GPM) always better? With the 10 gallon ATV Sprayer I could mount it on a trailer or put in a pull wagon.
I sprayed my Apple Trees today for aphids and it took 4 gallons. The trees are immature and i have 4 more trees coming next year so I think a 10 gallon tank would be adequate.

Northern Tool website has a Q & A section. Maybe their reps can better advise.
I would opt for the 15 gallon. You never get the last drop out of the tank and as your trees grow they will take more spray and you will definitely fall victim to the “…I think I can fit that just one new variety I just read about…” syndrome and then you will have a 10 gallon garden decoration.

( A.M. Leonard). They also sell sprayers

Northern Tool makes a $25 agitator that may help: http://www.northerntool.com/shop/tools/product_200028974_200028974
They have a PDF that shows the installation on Northern Tool sprayers. I would expect to loose about half of the pump pressure and flow rate to keep the bypass agitator working. They may have support to help choose the proper replacement pump.
