Thank you Jason for giving back to then lawn care profession with videos like this one. This year will be my first year spraying and I really needed an accurate way to calibrate the used sprayer that I recently purchased. You are an inspiration to so many of us.!
We are looking to get down 2 gallons per minute on 1000 sqft. After calibrating, it looks like we are at only 85 oz per 1000 when using the 2.0 yellow tip from lesco. I have ordered a 3.0 green tip, but wanted to know if there was any problem with upping the pressure a bit till it comes in? Any idea what the gpm was on the nozzle used in this video?
Have a graham sprayer. It came with a 3gpm nozzle. When I calibrated the sprayer its spraying at 1.36g per 1,000sqft. Its this a good rate to spray fertilizer and soil amendments? All my herbicides i am using d flowzone backpack sprayers
+Chris Elms glad you enjoyed it. I don't think this will be my most popular video because not everybody needs to understand this. But for those who do, hopefully it will be helpful
Jason..im looking at that exact sprayer for my biz...a couple questions about the video. first off....pressure wasn't mentioned. Approximately what pressure was he running. Being that I'm here in Texas, wind drift is always an issue. Sounds like his tip of running a larger volume (2-3 gallons per 1000) would be beneficial overall in my area. I have a handful of customers requesting applications, and have been trying to figure out what I need to get. I already have my commercial applicators license, and gen liability insurance. Can you also provide more info about what gun/tip he was using. Very helpful video.....am REALLY hope to get into this portion of the industry for 2018. Thanks! Is it hard to clean tanks after use? going from one chemical to another....what steps are involved to ensure I don't apply the wrong chemical to a lawn. I'm guessing it would be best to keep sterilants in a stand alone sprayer rig to ensure there is no cross contamination. The reason I ask that is because I have already been doing some of that type of work on a few commercial properties that I take care of using backpack sprayers (for cracks/crevice type stuff). My other option instead of this 200 gallon unit is the Gregson clark sprayer that has the small boom and mounts inside the lesco type walk behind Fert Spreader. My concern with a boom is wind drift. My thought is the gun would ensure less drift vs the booms. I know...long post, but hope you can provide some assistance here. Thanks so much, and happy holidays!
+rbljackson I can't speak so much for the tank that was shown in the video because that's not my time. Many people use a Lesco gun. That is what I use. I think you are correct in saying that more water volume would cut down on the Wind Drift if that is a concern. Cross-contamination could become a concern depending on what chemical is in a tank. Sometimes I try to cycle clean water through the tank to remove as much of a particular herbicide as possible. There is a lot to learn in the weed control and fertilization business. You need to put together a program so that you know what you are planning to spray and when you are planning to spray it on certain grass types
Great video. Did you do any videos at your conference a few weeks ago? how did it go? I wanted to attend...maybe i'll be able to if you have another one.
The main reason is the trainee will focus on not spraying outside the square and that will usually change his pace and arm movement with that attempt. The ultimate goal is to have used the right amount of product per 1000 sq. ft. when a lawn treatment is completed. There are several good ways to approach calibration. This is just one.
I just started working for a Company they spray 4 gallons per 1000 sqft the tank we use is 150 gallons for lawn and 50 gallons for shrubs im sorry I’m not getting the math not clicking please help
+Scott Allison I would say it would be important to check your accuracy on lawns on a weekly basis. I don't check my water level after every lawn. As far as calibration like was demonstrated in this video, I don't see a reason to do it often unless something has changed. Perhaps twice a year would be a good amount. I would be interested to hear others opinion on the question
Find the spread width of your spreader and from there measure out your test length to get 1000 sq ft. I just use a straight line. Once you have that, find the recommended amount of product to be applied per 1k sq ft. Let's say 4 lbs of fertilizer per 1000. Measure out 5 lbs, put it in the hopper, apply it over the 1000 sq ft area. If you have some left over, weigh the remaining amount. If you come out with 1 lb left over, you're perfect. If you run out in the 1000 sq ft test area, you're applying too much. If you're under or over, adjust the flow opening accordingly.
Basically you're just spreading in a known area of 1000 sq ft. And aiming to get the spreader to apply whatever the recommended rate is in that area by trial and error. Know your starting weight, and weight the leftover material.
Personally I think that's way to much square footage in the time frame. To low of volume as well. In Florida you can't run that low of volume unless you want poor fert, weed, and insect control. I'm sure further up north you can get away with this.

Great guest! I’ve known James for years. What a great guy! He’s been a supporter of the ATA for years.
Thank you for this! Math has always given me issues but this makes the process much more simple.
Still THE best calibrating video on RUclips
Thank you. James is very knowledgeable and a good teacher
Still The best calibration video in 2023. Thanks Jason.
2024??
PSI and label requirements for minimum volume of carrier is also something to keep in mind. Great video

I would try it and see if it clogs the filter. I would think it would be fine
@@lawncarelife ok thanks. Do you like the 2gpm or 3gpm nozzle better and is one better than the other?
Very helpful video can’t tell you how many times be watched it! Thank you
Great vid. Thats why i like standup sprayers bc if the technician sneezes...whoopps there goes the calibration. Lol.
+Doug Smith I see your point. There are definitely pros and cons of using a ride on sprayer. A consistent speed would be a pro
This is a good video Jason. More like this.
+Chris Elms glad you enjoyed it. I don't think this will be my most popular video because not everybody needs to understand this. But for those who do, hopefully it will be helpful
If you have a sprayer with 7 nozzles, do you take the water from one nozzle and multiply by 7?
Wondering what's up with my sprayer LOL. My hypro D403 won't already but 80oz/15 seconds (320oz/minute).
Mine also only has a 4' wide span
what psi were you running on here and nozzle and rpm of engine?
i feel so sorry for that applicator, what about if it was a windy day? is it the right way to spray?
What size hose do you use? 300' x 1/2"?

If you have your applicator license you should already know what the eff your doing
Is that nozzle a 4.0gpm ?
Great video. Did you do any videos at your conference a few weeks ago? how did it go? I wanted to attend...maybe i'll be able to if you have another one.
+TJ I do have a little bit of video footage from the conference. I plan to do a video telling how the Conference went
i feel like its to complicated that way. i mark 1000 sq feet adjust my speed and pressure to 2 gallons per 1000 with a stop watch and bucket.

My buddy James! Haven’t seen James in a while. Need to call him and chat sometime. Good job on teaching calibration!
What gallon per minute nozzle was on that Teejet gun?
I just started working for a Company they spray 4 gallons per 1000 sqft the tank we use is 150 gallons for lawn and 50 gallons for shrubs im sorry I’m not getting the math not clicking please help
What’s the best quimical for weed control in Canada?
How often should you calibrate?

I need to learn to trust the chemical I feel that what I’m putting down is not covering enough to do the hob 😔😔
Thank you for the informative video. Harrell’s is located in my community. A first class corporation.
Very very helpful thank you
Great video. Thanks
Can you put the formula on here? It looks like he had 1000 written but said 100
1000 was correct. My mistake!
Great video, could you do one on how to calibrate a broadcast spreader?

Just my opinion and experience. Our turf grasses are thick and hard to penetrate.
1:40 for the best truck ever built
This hurts my brain
When you say 1000 that means acres
David Rodriguez it means every 1000 square feet
