3 point boom sprayer build

[Eyecatcher]

Recently bought a skid mount spray rig as golf course surplus. Been run hard and left wet, but basicly pretty sound. 150 gal tank mounted on a heavy aluminum frame (marked Weed Systems model 430). Hypro D30 pump w/ Honda GX160. Hose reel on top, and 12' of boom on rear. Got the engine running, and pump looks to be in good shape. Would like to 3 point mount. Would have to bolt hitch arrangement on, since can't weld aluminum. Several questions: 150 gal @ 8#/gal=1200#
Pump, motor, sprayboom etc., cantilevered back from hitch, how heavy will the mount have to be made? The pump is capable of 580 psi. What is the normal pressure used in a boom spray system? Hose reel has a Greene Garde JD9C valve/nozzle on it. How much pressure usual for that? Intend to spray herbicides, insecticides and possibly fertilize on 1 acre garden plot. My tractor handles a 3 point 7' bush hog well, so don't think cantilevered weight will be a problem. I'm open to all suggestions, and sure would like to see some pix of home built 3 point sprayers.

The sprayer you referenced is way overkill for 1 acre. About 15 gallons of fluid is all that is required for 1 acre.

I realize it's way too big, but I have a total of ten acres, and my son has 17. I've been using a little 25 gallon wand sprayer in the back of the utv, but it doesn't lend itself to "burn down" of grass prior to planting, and the big sprayer was a buy - don't have to fill the tank up!

I have this for sale $100 ...no pump on it though

Little too far away.

You could just get a 3-point pallet fork to put the sprayer on

I believe that normal spray pressures fall between 10 and 30 psi. Any higher can cause too much atomization which is too small a droplet which increases drift and possible damage to surrounding areas.

Depends on nozzle type .All full size self propelled that i know generally run 40-60 psi , Ours is not happy below 45 psi .

Been working on this spray rig, on and off since my first post. Got the hose reel rblt and epoxy coated, the pump gone over,(waiting for parts), so time to think about the 3ph. Rainy day, so have been web surfing, and saw an article that got me to thinking. How about a front mount, vs. 3 point? Have FEL w/ quick attach. Thinking about turning the whole thing around backwards, building a quick attach frame on it, and have the spray booms on the front. What are the advantages and disadvantages of having the spray boom out front, other than driving thru the spray? Would like to have this thing set up so that I could spray my corn to keep the worms off the roasting ears, by using the vertical part of the folding boom. Should be easier to see what I'm doing! Whatta ya think?

You are correct D7. When I ran a spray coupe we ran in this range. Although it would go to about 30 psi before nozzles started shutting down. This was due to the no drip valves at each one.

The Haggie and Nitro sprayers run a front boom but they have nozzles behind each tire other wise as you drive over the sprayed area the tires wipe the spray off the plants and you get tire tracks that don't die. But nothing wrong with having 2 ways to carry it. Set it up regular and for loader.

If you have very hilly terrain may I suggest adding a boomless nozzle otherwise it gets hard to control boom height if very wide. We have a teejet nozzle with five sprayers on it and it will cover a 50 foot swath. But we spray about 200 acres of pasture and hay ground with it each year so speed matters.

Make sure your pressure relief valve is good if your pump is capable of those pressures.
