Pull behind sprayer

I decided to buy a 25 gallon, 4 nozzle

Pull behind sprayer from RK.
Had to drive a Avon. Many stores were out of stock.
I'll test it out after I cool off.

It has a wand and adjustable pressure. Different heights for boom. I'm thinking of making a hood to keep spray from drifting on lawn and flowers.

I want a trailer to keep spray away from me. I can easily put it in the trunk and take it to my other property.

Planning to test the spray pattern using just water.

Need to wait until the rain stops in a few days.

I built a sprayer like that from a 14 gallon ATV sprayer with a 12V diaphram pump, 4 spray nozzels from the field sprayer aisle of Farm & Fleet, 25 ft of hose, couple elbows, a tee, couple shut off valves, even got strainers for the nozzels. Figuring backwards I had to go 1.15 mph to cover the 80 inch swath, 1800 rpm in 1st gear with my gear drive Cub Cadet. Wired the cord up direct to the battery, wired an on/off switch into the wire, even put a pressure guage in the line right before the spray boom. Sprayed the yard 10-12 years with that sprayer.
I bought a crabgrass herbacide, wettable powder, toss the whole plastic bag in the sprayer tank, bag, powder, it all dissolves and I needed a bigger pump, so bought a HyPro roller pump and 55-60 gallon tank. Took a while to get the pressure and nozzel flow correct, but sprayed 3-4 times with it too. Didn't have great success with that version.
SON was out with a $15,000 professional lawn care spreader/sprayer combination. He put down 250# of fertilizer and 60 gallon of 2-4D over my heavily forested 2+ acres in about 2 hours. The sprayer has the CUTEST little foam marker system, poops out a marshmellow sized piece of foam about every 10 feet, either end of the boom. I considered GPS and auto-steer for my Cub Cadet when I sprayed with it years ago. We had lots of crushed granite landscape rock with different kinds of evergreen bushes all around our house. The leaves and dust had accumulated for 20+ years and I'd have to spray Roundup 2-3 times a year and around all the trees/bushes in the yard. Have some bushes that still have bare ground around them.

Yep, close to 30 years ago I switched to spraying for weed control.

I bought a sprayer like that last year from Rural King. It works good. Don't see why you need to add a hood if you spray early enough in the morning before the wind picks up. You could try it out with plain water to see how it does.

I did test it with just water. About 20 psi.
Decided to spray the concrete floor in pole barn. I may up the pressure. What pressure do you use?

Lower pressure means less drift higher pressure more drift because the droplets are finer

Several years ago, I fabricated one from scratch using a 60 gallon tank, with spring loaded folding booms covering a 12 ' swath.

Works great behind an 18hp garden tractor, and my wife can spray our entire house yard with one load.

That's what it looked like on the pole barn floor. I think large drops should kill grass and weeds in driveway. What do you think?
I've been using 1 oz of RM43 per gallon. Is that enough?

My BIG sprayer was 55-60 gallons. My 10 HP Cub Cadet handled it fine. My yards pretty flat. I have way over 100 trees & bushes on my 2.3 acres, My boom is a bit over 5 ft wide. Driving by the last set of tire tracks in the grass the smaller boom gets you closer to the tracks to see them better but more passes and places for gaps between passes.
The foam marker system on the sprayer SON used here a week ago was very compact, see-thru plastic soap tank held about a gallon, pump & motor about the size of tank, two 3/8 rubber tubes like gas line that run to each end of boom. Not sure how it worked but it knew which side to drop foam on. On a boom 12 ft wide I would want something to drive by.
I had bought five 1# bags of a wettable powder Dimension pre-emergent crabgrass herbacide. Just toss the whole bag, or maybe it was 2 bags in each tank, and aggitate, and keep aggitating some even while spraying, the reason for the much bigger roller pump, 9 GPM and up to 150 psi. I needed 7 gpm and 60 psi, I used a TEE-Jet flat fan nozzle, less chance of plugging. I forget what each nozzel flowed, I ran tractor about half throttle, plenty of power. I had a laser photo tachometer to check engine rpm before I started spraying. I tried using a Tiny Tach twice to hold engine rpm and both failed in a very short period of time.

Im not familiar with that one . The label should give you recommendation on ounces per gallon though

Worried about drift. Get a set of these with check ball strainers. Set your boom at 20 inches. These are driftless at 15-40psi. Bigger drops so need to slow down. Check Teejet.com. Spray on brother.

Few years back, I bought the TSC version of the same sprayer. The on/off switch lasted the first season. I had a spare marine switch.
Not OSHA approved(smile).


FWIW...I usually run 25psi.

HTH,
Don

Mine came with strainer and blue nozzle.
Thanks for your help

The spray tips on my shop-built rig recommended 40 PSI. They are Tee Jet brand. I idle up the 6 roller pump to read 44 PSI, then when the solenoid valve opens, the pressure dials in at 40 PSI. Don't get much/any drift from this combo, 8 tips spaced @ 20" on a 12" boom, @ 20" spray height. The spacing and spray height were also recommended on a chart on the pack the tips came in.

I have had the TC model for 10+ years and it has preformed well. I strap it in the Mule box and find I get 25 Gal per acre at about 4-5 mph., as slow as I can go. My pump diaphragms must be failing, it has trouble getting a suction started.

I have one of those. Would like to modify it with a bigger pump and more sprayers. Already put on different nozzles for a better spray. I can stick it in the back of the pickup and run an extension with switch up to the lighter power plug in the cab.
