Hey guys, thanks for all the good discussion, and always nice to have a pat on the back. Haha.
Thats a good topic, what is the typical life expectancy of plastic tips? Our pull type sprayer has same tips as new but we spray in a year what most guys do in a few days. Alternating between 5 and 10 gallon tips we may have 15,000 acres on a set of tips so when does a guy start to pay attention to potential tip wear? Does running higher pressures come into play to accelerate wear also? Seems like for me it is one of those items that is not really worth testing, if you think you have reached the typical life expectancy than just buy new ones and be good till the sprayer gets replaced due to old age.
Good questions @kenmb
It's tough to gauge lift expectancy.
In short (like really short), a lot of guys replace them every 50-60k acres. Again, that is a rough idea just so they dont have to bother with calibrating the tips and doing all the extra work. Realistically though, you could have need to replace them before that 50k acres for sure, depending on your circumstances.
In long (like really long), water quality is the main proponent in tip wear. If water quality is excellent (i.e. filtering 2-3 times before getting to sprayer tank, then 2-3 times while going through the sprayer), then expect your tips to last a lot longer.
For plastic tips, chemicals used can typically make a big difference in wear. Not that it happens often, but different types of plastic that are used in spray tip/caps (i.e. celcon, glass-reinforce polypropylene, etc.) have their own weak points in chemicals. Just remember plastic is not equal to plastic all the time. Some plastics are more stiff but less chemically resistant.
For stainless tips (what Wilger tips use), chem doesn't make much of a difference in wear to my knowledge. The main wear on stainless is water quality. Little would you guess that poor water (like really poor, pulling from the gravel pit straight to the sprayer kind of poor) would likely wear stainless tips faster than a plastic tip.
For ceramic tips, to be honest, I don't deal with too often, so rather than make something up, I'd just say they are supposed to be better than plastic and on-par (or marketed as 'better') as stainless tips.
For pressure, higher pressure does give the nastier water quality more wear on the tips. Makes sense. If the water is nice and clean, its probably not as bad as you'd think. If you are okay (drift-wise) to spray at higher pressures, then I wouldn't let tip wear be the main factor in not spraying at those pressures.
For calibrating (when to replace), usually the tips come from the factory within 3%, so as soon as your tips vary from the intended flow rate by 10% or more, it'd be high time to replace them. For those who don't know, the intended flow rate is right on your cap. When you see 'SR110-03', that is broken down to the specs of the tip:
SR=the series of the tip, 110=the angle of the tip,-03= the flow rate (usgpm) at 40PSI (@ 80°F water), so an -03 would be 0.3 US gallons/minute. This is standard across all tip manufacturers, so a blue tip flows the same as a blue tip.
To make it easier for calibrating, there are a few tools out there that can make it a ton easier to calibrate or decide if your tips are too worn. Namely, Spot-On (~$150+) or Applimax's calibrator (~$500). With them, you just put it under your tip, running at 40PSI, and it'll give you the flow rate.
Is there anything on the market to test the output of individual tips?
Hey Swath Chaser, a few options for calibrating just above this.

Hate to say it, but we use Teejet tips/bodies... why? Sprayer came with them, basically, then we added tristream fertilizer nozzles and twinjets for better coverage.
Next sprayer... who knows. Maybe a Hagie. Maybe a Rogator. LOL.
Hey, it'll be good to see you at the show. Who knows, it might even be a green hagie.
Haha I don't even wanna win, I always get a pile of free tickets from different business I deal with, and I haven't gone in years!! Hopefully this year, I'm two weeks ahead of schedule so should be done spraying by then?? I will be checking out your website...
Just as long as we don't get another month of winter in the next week or so, you should be in good shape. Haha.
Wilger Industries definitely has the best website, namely Tip wizard for choosing your nozzles. I cut and paste your tip charts on the tips I am using to Word or Excel than print them off in a very large font so each chart fills a full page and keep them in cab of sprayer for reference. I see you have changed your charts since the last time I printed off charts. Are the old charts still available?
+1. Tip Wizard makes my job so much easier. We had just reprogrammed it to give better results and give more information, as well as add a kind of legend that would give an idea of what each column is, for those who are just looking at it for the first time.
I'm just finishing up a little guide for using Tip Wizard that makes it a lot easier to understand from start to finish, to get the very most out of the tool.
The old charts are still available. They should be available in the DOWNLOADS section of the website. If you are meaning the old tip wizard charts, then those will be phased out right away. The data is the same (in some places, we fixed errors in how it was showing, so it is better).
The tip wizrd is a very good information source on Wilgar nozzles. I was wondering if Wilgar makes any twin nozzles like the twin turbo Teejet nozzle? We have used twin nozzles and like the coverage they provide.
For twins, we are likely only going to stay with our Wye adapter for multi-tip spraying. Usually for those high volume fungicide kind of applications, you'd have tips on hand that you can plug on to get the application (rather than buy two sets of tips completely).
The other thing is that you can still get the drift reduction (without sacrificing much coverage) so you get physically more flow hitting target. If you are using the twin turbos, they essentially spray as 2x conventional spray tips, so they can get pretty darn drifty.
Well don't have any Wilger tips or such but I do use one of the last actual sprayers they built, Jumbo 880, always been quite happy with it. Reminds me I never did follow up with you Lucas about those decals and such we had discussed in some emails a year or two ago.
Don't put my name in the hat, no way I'll ever get down that way for the show, best someone else get them. Nice offer regardless, thanks
Not even kidding, every year I get about a dozen calls for parts or manuals for the old Wilger sprayers. To put it into perspective, most of these sprayers have been running since the late 80s and early 90s (I think the last production year of the Wilger sprayers was '92). Just this week I sent a fellow home with another set of tank graduation decals. Speaking of decals, I do know we have probably half a dozen sets at the factory now, and I know exactly where they are.
Remember how cutting edge Wilger sprayers were when the first came out, wow, a boom wheel with a suspension on it and a stainless tank, what a marvel!
No kidding. It was pretty amazing, as farmers will come up to me at the show and literally tell me that they'd buy the Wilger sprayers sight unseen without even knowing any of the new features to the sprayers, as they knew it'd be great. It was a waay before my time with Wilger, but it is pretty awesome that the company still maintains that loyalty for over 30 years.
we use wilger tips with our aim command system, nice to have the tip wizard, makes choosing tips a lot easier. it would be interesting to see a chart in one location that shows the optimal droplet range for each chemical out there. I haven't seen that in one easy to read chart, would be nice especially with the aim command, I think it would be a great addition to the tip wizard.
+1. On the recommended chem side of things, I feel your pain. As far as the liability side of things, I'm sure you are pretty well aware that kind of information would have to come from the chem mfgs. BUT, that doesn't mean you are completely hooped.
For example, find the link to the Saskatchewan Crop Production Guide (2016) -http://www.publications.gov.sk.ca/details.cfm?p=77706
Note that the guide references the chem labels based on the OLD ASABE S572 standard which is as follows:
FINE (150-250 microns)
MEDIUM (250-350 microns)
COARSE (350-450 microns)
VERY COARSE (450-550 microns)
EXTREMELY COARSE (550+ microns)
From that, you'd be at least within 100 microns of the chem labels. As far as a comparison, 100 microns is the width of a hair, so even if you are adjusting the base number of the category based on your conditions (i.e. spraying into windier conditions often might mean +50-75 microns to your baseline droplet size).
At least something to help you out a bit.
Albertabuck if you decide to upgrade to a newer wheel boom sprayer I would look at a flexicoil 67xl sprayer. They are a rugged sprayer and have well designed booms that seem to go forever. The booms fold nicley from the cab. They however never came with a stainless tank. We had a 120 ft with 1600 gallon tank.
As a side note, for anyone who might have a 67XL who has a busted tank, I think I saw a few for auction at PBR Auctions in Saskatoon. Otherwise, the tank has been discontinued and I don't think they can run the mold for it anymore. They look like un-used tanks from CNH's yard.
