Was thinking about an issue I have with my sprayer, that being some sort of contamination in the booms that breaks away and plugs nozzles from time to time (VERY annoying) and how to clean the pipes. Tough since i don't know what it is that is in there. So I was thinking about perhaps running diesel through and letting o]it soak then thought, "Perhaps I could just use diesel to winterize it". Cost would be about the same as the RV anti-freeze that I have been using. Can't think of anything in the system that would be adversely affected by diesel. May or may not (likely not) help with the contamination problem but would be a lot more convenient than RV antifreeze. Of course there is the environmental issue of spraying out 35 gallons of diesel but I would put it where I don't want anything to grow (where I often rinse my sprayer in the summer.) Thoughts??.

Nozzle screens...

Have never had a problem with diesel in the mix, petroleum distillates are sprayed all the time. Never thought of using it as antifreeze but that's a great idea. You wouldn't even need to dump it before adding water and chemical if you're doing burn down.

Environmental **** is for the californians. This is the bush.

The diesel will separate from the water and the water will still freeze. If you have crap on your booms run some 28-00 through it or some liberty. Diesel is way to expensive. Used diesel on the service rig to flush the pump at the end of the day. 2 pails a day That added up to a lot at the end of the month.

Have considered that but I don't like the idea of nozzle screens and that would just be treating the symptom rather than the cause.

That was my thought as well.

Yes but the diesel would provide room of the expansion so there should be no ill effects from the frost.

I thought about 20-0-0 but hadn't tried it. Sprayed lots of Liberty hoping it would clean it out but to no avail.

Same price as RV antifreeze. Actually a bit cheaper. $100 to do the sprayer either way.

Just hook a air line up to pump with 120 PSI then shut off all boom sections turn one section ON at a time works real good .The Apache service techs do it all the time.
I've thought about that as I hear other do it but am unsure how to get the agitation, chem educator and rinse tank system clean with air.

those nozzles that you can put on the ends of the boom do help, also...
i just drain mine, and don't add anything, leave it -slightly- open for the winter, so far it's been good ..

I do find it a bit interesting that everyone is using antifreeze now as the standard practice used to just be drain everything. As long as everything is adequately drained there is no problem. I think the antifreeze is good because it is more forgiving if you screw up draining.

Around here guys are getting 115L barrels of windshield washer fluid and using about half a barrel for winterizing. It’s pretty cheap stuff when buying it this way, likely under $2.50/L. Not sure if it would clean booms any better then what you’re already thinking though.

Dawn soap will keep the diesel and any water left in solution.

Diesel has the convenience and speed factor you don't get with other stuff.

That’s what I do. Never had a problem yet over 20 years.

We've been using air to purge our pull-type sprayer for many years. Never had any problems cleaning out the chemical inductor. The hose from the inductor has a section that sags down a bit and that never completely empties, but it's not enough water to hurt anything (flexible-ish hose anyway).

The patriot is new to us, so I haven't decided how to winterize it yet (believe it or not we hope to spray Reglone next week yet). When we got it it had been winterized with antifreeze and still had broken fittings. So I'm leaning towards using air again on it. If there are some areas where water will collect and not blow out, I may disconnect those fittings and let them drain. For example the hose sucking out of the bottom of the inductor.

But I like the idea of the windshield washer fluid.

Of course air wouldn't help you with your problem of wanting to clean out chemical precipitates.

When you are spraying it out to rinse, could try moving any hoses that are commonly bent around to try make sure if there are any cracks inside the hose holding chem or breaking down a bit, you might have a better chance at dislodging bits of hose or chem. Also, when flushing, not sure how high you are setting your pressure, but you could go a bit higher to make sure your hoses are expanding as they would in normal spraying circumstances too.

As far as winterizing, most 120' sprayers have like ~27 gallons of liquid in the plumbing fittings and pipe/hose all the way down to the nozzle, so plan accordingly. If you have a PWM system, you'd want a bit more than that to give the solenoids enough time to rinse out the nooks and crannies in the solenoid. If you have colored antifreeze or washer fluid, make sure to run the system until you get nice color from the last of your nozzles/sections, and then give it a bit more.

As far as anti-freeze vs. washer fluid, anti-freeze is cheap insurance. Bear in mind where the sprayer is being stored and what kind of temps you'd be getting at. Last winter was especially nasty, and we had -45°C glycol (not diluted, tested at -45°C too) freeze solid at the shop, which caused a whole lot of expensive grief. Albeit, it was 1/4" lines through a chiller, but still, plan for your worst winter.

Washer fluid might be OK to store a sprayer in the south, but up here in central Saskatchewan, it'd be asking for a whole lotta grief.

I'm curious, if you have that much water still in your sprayer after pulling the plug, does it ever get clean?

Don't ask questions you don't want to know the answer to.....lol :sFun_whistle:

Think Tom Wolf/Sprayers 101 did a pretty good shpeal on that, and at least as far as the tank is concerned, a triple rinse of the tank would get dilution down to something like 0.25%. Assuming that is one of the easiest parts of the sprayer to effectively 'rinse', you can only imagine there are some nooks and crannies that get less than ideal dilution without pulling the nozzle bodies and boom pipe off and giving it some elbow grease.

When I winterize my Rogator with 120' Pommier boom I just drain everything out, which is easy because the re-circulating boom is long straight pipes. Then I add 60L of sprayer antifreeze and let it run for a bit, then spray it out.

Yet another advantage of the re-circulating boom.:smile:

Still have a half tank of glyphosate in there I'm hoping to get sprayed though, starting to wonder if that will happen.

That’s pretty pricey from what I’ve found searching around locally. Pails as low as $1.52/l totes are half of that.

I drain everything out then put about 5-10 gal RV antifreeze in the system and spray it out. Never had a problem this way. I do blow out the booms with built in air system. Blowing them out alone has not been perfect fro me. The triple rinse idea also helps with winterizing. Run the anti freeze of your choice through 3 times.

I would also like to know a great thing to put through a sprayer to clean it out. I have used tank cleaners and such and still get yellow stuff plugging a few nozzles each year. I have never used anything yellow. Has to still be in it from before I got it. I have boom flush valves and tried flushing each boom section a number of times. Clean all the screen a few times each year. Getting better but still in it somewhere.
