I have recently started looking into building my own custom 50 gallon lawn sprayer.
I spray a handful of properties every year and my 30 gallon trailer sprayer is somewhat annoying in 4 categories.
1. Spray width roughly 8 feet.
2. Spray hose gun length.
3. It's a trailer.
4. 30 gallons isn't enough.

So let's dive into this. I own a JD X758, no 3ph or CnG brackets. I have looked into the 40gal 3 point set ups ($500), the two downsides I see there is I have to install the 3ph which is like $700 and buy the sprayer. I'd be looking at $12-1300 to gain 10 gallons, 2ft wider spray, and lose the trailer. Things I fear of this set up is overloading the 3ph, and not being able to keep the front end on the ground since I'd be holding around 400 lbs 3 feet off the rear of the mini tractor.
Then there is the john deere click and go set up. 25 gallon tractor mounted sprayer gtfo... no thanks.

So here's what I'm thinking, using a 50 gallon narrow tank mounted to a homebrew bracket that would slide into something to the effect of 2x2x1/4 steel tubing that's attached to the same area the 3ph connects on both sides.
The sprayer arms... I'm considering an overall physical width of 14ft (16ft spray coverage). 6 foot main section with 4 foot hydrulic folding wings. Using the hydrulic valve that allows for floating, this would be an easy way to allow the arms to be moved manually if needed. Using something to the effect of a 50ft retractable hose reel for the spray wand. This needs length due to the rear being wider than the tires, I will have 3 areas I can no longer fit (by going 6ft wide center beam) into since currently the tires rub the gate to enter lmao. Something I'm considering using also is a master control box, running a large set of +/- wires to a quick connect at the rear to plug in a fuse/relay box. This will control 3 solenoid valves, for selective spraying of each boom, lights on each end of the boom, the pump, and a solenoid valve for the spray wand.

Originally I was thinking of having the outside booms fold upward, but have since considered having them forward along the tractor due to needing a narrow width while under trees at 2 properties.

Here's some pictures to chew on.

Not to hijack the thread but curious what you are using for product to spray on your lawns? Just purchased a spinner spreader after researching and really wanting a sprayer. Dealers and fertilizer suppliers talked me out of going with a liquid fertilizer. I would have to order from limited suppliers on the internet which didn't seem to fit my routines of treating my lawn. Thanks for your time and good luck with your build, it was difficult finding a prebuilt sprayer with all the features I would have liked

Will you be able to keep your front wheels firmly on the ground with 400+ lbs of water on a tank hanging off the back?

Just spitballing a little bit here but could you build the system like you're thinking but re-use your existing tank for the back and then mount a smaller (20-25 gallon) tank on the front with a small electric transfer pump between them?

Here’s the ideal rig! Boom mounted on tailgate folds up out of the way for narrow gaps and out of the way when using wand! The chains on the gate allow to raise or lower boom. I can easily slide this spray rig in and out of the trailer if I need it for other stuff. And I don’t have a bunch of weight on my mower! I could easily pull with other equipment!
I also don’t have spray directly behind me.

I was recently asked in a private message about what I'm spraying on the lawns.
Due to certain connections with certain people. I came into owning roughly 1000 gallons of liquid fertilizer. 800 gallons for lawn care, 150 gallons for garden use, 20 gallons of surfactant, and 30 gallons of everything killer. Call it a lifetime supply considering the mixing rate is incredibly low due to it being commercial products. This stuff is for my property only. It's from precision labs golf course collection for the most part.
Other things I commonly spray is Bifen 7.9 insecticide, not a single bug on any of the properties for roughly 3 months. No mosquitoes, boxelders, earwigs, millipedes, or ticks which is a good thing for the boys. Triplet is another common one for each property along with quinclorlac 75 DF.

Oh, I also made a flame thrower out of a 8 gallon tank sprayer too :) I have since mounted the 8 gallon tank and propane tank to one of those reciever carry-alls and put it into the reciever hitch on the front of the deer rofl.

After I get this sprayer figured out, the next thing is to get a pellet spreader for pre emergent/milorganite/lime/salt.

I didn't even think of that!
The solution currently would be the JD BM19780, they are suitcase weights that are 70lbs a piece. I really like your suggestion though and will think about it for future expansion!

I have considered that option as I have the 21 steel cart from john deere. I would in that case probably move up to a 100~ gallon tank.
Two issues I have with it are...
1. The tractor and trailer don't fit on my damn trailer hooked up, it REALLY irritates me actually.
2. I'll still have a trailer, which wouldn't be nearly as bad with a long hose reel. I'm truly about 50/50 split on the option.

Off topic, why are these trailers made to do such a nose dive?

Unhook the spray rig and turn it sideways on the trailer behind the mower. 8x50= 400lbs plus the sprayer and trailer. 8x100=800lbs plus the sprayer and trailer. Now I'm sure that is a legit mower but could it handle that kind of weight pushing/pulling it on slopes?
I certainly wouldn't go over the 50 gallon tank and use a mower for pulling. Just saying.

I had honestly figured with the weight I've seen some of these guys get up to in attachments I'd be fine on flat ground toting roughly 1200lbs. That being said I wouldn't dare do that on my property, too many slopes and transitions. My property I can cover in about 50 gallons anyways. Would just be nice to have the extra capacity when needed/useable.
I truly never have looked into what it would be rated to pull on flat ground though....

A quick look on Tractor Data shows the X758 coming in at around 1200lbs +- depending on the set up.
I'm sure an owners manual would mention GVW weights on the front and rear.

Love the dogs btw!

So get this.... I was reading through the manual.
John Deere rates the x758 at 9 42lb front weights, 2 30lb front wheel weights, and 850lbs of rear max ballast.
1288lbs of ballast on a 1200lb mower lmao. That's a lot of pounds on the ground!
These transmissions must be rated for more than I thought.

Speaking of the pups, Wrigley was supposed to have no pit or rot in him..... uh huh surely he don't. Bruno on the other hand, I know this may come as a surprise, is a purebred GSD rofl.

Look at this lovely little craigslist find... http://madison.craigslist.org/grd/d/atv-or-utv-pull-type-sprayer/6558733838.html

I have a Fimco 40 gallon 3 point sprayer that I use on my 1025R.

I use:

Dimension Pre-emergent: https://www.amazon.com/gp/product/B0056650Z8/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1

Gordons Trimec lawn weed killer: https://www.tractorsupply.com/tsc/product/gordons-liquid-lawn-pasture-fertilizer-20-0-0-with-micronutrients-2-1-2-gal?cm_vc=-10005

And

Gordons Lawn and Pasture Fertilizer: https://www.tractorsupply.com/tsc/product/gordons-trimec-lawn-weed-killer-2-1-2-gal?cm_vc=-10005

I see good results with these.

I'm really surprised at how building one is so uncommon... there's nothing special to it and it's relatively cheap. Sprays a good 20-25ft with the upgraded northern stool wand. 2 gallons of gasoline to 5 1/2 gallons diesel is about perfect. By technicality it's semi safe as long as the 8 gallon tank isn't ran dry. Because as long as the fuel mixture is under pressure in the hose, there's no way of the flame traveling back to the tank because there is no oxygen in the hose. If I spill gasoline while pouring it in, I just spill some diesel on it... logic...
For every tank full you get around an hour of fun. I was originally looking into the X products flame thrower... but when I saw the run time, I instantly looked for an alternative. I went down to the girls parents one weekend and dropped around 45 mature trees on Saturday, by the time Sunday rolled around, 4 chainsaw chains later we had the brush stacked and lit. I put 6 gallons of fuel through my Stihl MS391 that weekend....

I accept ZERO liability for anything anyone does with using my photos as a basis upon building one.

Oh you want more pictures? No problem!

I wouldn't worry too much about the weight on the X.

My X585 comes in at about 1000# with no attachments. I have the 3pt hitch, HF quick hitch, heavy hitch with 6 suitcase weights. Plus fluid filled back tires and my CTC FEL. Before picking anything up and me on the machine, I would estimate it comes in around 2000#. Then I pick up another 600# or so with the FEL and it takes it and asks for more. The biggest problem is keeping the front end on the ground.

I am actually thinking about doing something very much like this project.

I have a 30 gallon cart I use. The problem is I have to take my 3pt hitch off to use it because with the arms, quick hitch, heavy hitch and 2" receiver the cart is so far back that the power cord barely reaches and the wand isn't long enough.

So my plan is to convert the cart into a 3pt hitch setup. I don't need to go up to 50 gallons and I already have the 3pt arms. I am thinking the main thing I will need is to come up with some spray nozzles. The cart I want to use doesn't have them. I actually have two carts. One has arms but is going to be harder to convert to 3pt. Do you have a source for what you are doing for the arms? I might have missed it if you posted something.

Holy crap, you have the ctc loader?!?! I wish I could find someone to play around with one local to me!
I'm actually planning to just build the boom arms myself, the few I've seen that are pre built look "okay", but you know, when you make it yourself it's better... oh and the more heavy, the more better lmao

Thank you for all the information.

If my mind hasn't gone totally out the window, I vaguely recall seeing all the parts for sprayers available in the big Northern Tool catalog that they send me once or twice a year. Boom arms, nozzles, pumps, hoses...

I don't have any photos of the sprayer I built and used for several years and it worked very well. I will post a picture of the main components and why i selected those to use....

I took a 2" hitch receiver like they sell at Lowes or the Tractor stores. etc. It's crucial to have flanges on the hitch receiver for either bolting it or pinning it on the tractors rear hitch plate. You can't use just the plain tube as the hardware to bolt it in place with get in the way of the ball mount since without the plate on it, the hardware to secure the tube will have to be in the tube, which won't work.



I bought an aluminum platform carrier designed to slide into the 2" receiver tube. Now, if you happen to find one which is the 1 1/4" square tube, obviously that would work as well. The smaller hitch tube carriers are often designed for the "bicycle carrier hitches" on many of the small compact cars or really small SUV's. What you want to end up with is an aluminum platform that will pivot up so that when used on a car hitch, it can be "flipped up" and stored at a 90 degree angle.

The pivoting part of this carrier platform is crucial as you need the platform to be able to float up when climbing steep inclines or going up ramps into a barn, etc.

Aluminum is helpful to keep the weight down and make handling the platform when not on the tractor a little easier.


Here is one at TSC to illustrate the product I am talking about,

https://www.tractorsupply.com/tsc/product/traveller-500-lb-aluminum-foldable-cargo-carrier-1223598?cm_mmc=feed-_-GoogleShopping-_-Product-_-1223598&gclid=Cj0KCQjwz7rXBRD9ARIsABfBl81hA1_HVjR5SpyUN0ltGfDJ7YcHvGcnq-hNX93VAEFqO4MaX4n5JFQaAoiUEALw_wcB

Now, this one shows a price of $129 but I was able to get one at another store on sale for $69.

Harbor freight has one for $85.....Just make sure it pivots on the mounting receiver as it needs to be able to "float" up and down behind your tractor or it will tear up the lawn when turning or on inclines and transition parts of the lawn from level of hills or bumps.



I mounted an inflated rubber tire which was on a 360 degree swivel on the rear of the platform in the center. This helps the platform carry the weight of the sprayer and it also allows the platform to "pivot up" as your terrain changes or you are loading and unloading the tractor on a trailer, etc. It simply won't work without the ability for the platform to pivot up and down to the level position when hooked to the tractor.



Here is an example of the rear wheel I mounted on the rear, center of the platform.
8" x 3" Black Pneumatic Tire Swivel Caster 300 lbs Capacity

Basically, once you have the platform positioned to mount onto the rear of your tractor, the height of the platform from the ground will determine how large of a swiveling caster wheel you will need. I found the inflatable tire left less of an impression on the lawn and grass than did a "hard tire". Simply drilling 4 holes in plate of the caster wheel, which most come this way for mounting, provides the ability to mount to the center rear frame of the platform with squared "U" bolts. Face all the hardware down as you want nothing to possibly puncture the tank you are going to mount on the platform.

I found a spray tank and wand of the capacity I needed and I placed the tank on the platform and secured it with ratchet tie down straps and eye bolts drilled through the aluminum tubing of the carrier on the front and rear of the tank.

How fancy you want to get with the spray bar or nozzles is up to you. I had mine set up to spray about 12' wide and I had 20' of hose with a hand held spray wand which I had gotten from Norther Tool for a higher quality spray wand.

The nice part of using this platform with the caster wheel is it didn't hang all of the weight off the rear of the tractor, but it did permit the platform to follow the tractor just as the MC519 cart does or anything which uses the Click n Go style mounting brackets. No separate cart or trailer needed. Being bolted to the tractor using the hitch, it is as easy as pulling the ball mount pin out of the 2" hitch mount out of the receiver and the entire platform is disconnected.

If you want to hang the weight off the rear of the tractor and have it follow you and NOT use the caster wheel, you can use this ATV carrier......This also fits the 2" hitch receiver but with this design, the weight would all be hanging on the rear of the tractor. Since water weighs about 7 pounds per gallon, plus the weight of the platform and sprayer, it gives you a choice for mounting styles. Normal retail price at Harbor Freight is only $49 for this ATV platform.



https://www.harborfreight.com/300-lb-capacity-atv-cargo-carrier-69858.html


Simple, provides good weight distribution, doesn't require any welding or real fabrication and eliminates the problem of the "trailer" or possible jack knifing when backing the tractor up with the sprayer attached. I had about $100 in the total platform, caster wheel and hitch receiver.

Also, you can use the platform as a "Utility Carrier" behind your tractor by simply removing the spray tank. I didn't take any photo's of it that I can find, and I gave it all away to a guy when my new tractor and implements arrived. He is using it on his smaller tractor and is happy with it.

Now that right there is an interesting concept I could get behind. I did relatively the same thing with my 8 gallon tank. Can't find an actual picture of it, it's in the background of a recent dually picture though!

Overall I am happy with the CTC now. There are some things I have had to modify to beef it up both on the tractor and FEL. I just mainly have to keep in mind that it is a small FEL system so I tend to ask more of it than it was designed. I was really disappointed when I first got it because I didn't re-shim the implement pressure relief valve right away. I went from about 900 PSI to 1200 PSI and that made a huge difference with the FEL. It went from being able to lift a 1/2 bucket of dirt 6" off the ground and giving up to lifting a full bucket and lifting the back tires off the ground while doing it.

I think you mentioned not having the 3pt or click and go. If you are looking at a FEL for this you are going to want to shim the imp pressure relief and you will need ballast. Like I mentioned I run winter grade washer fluid in the rear tires and 252# of suitcase weights on the heavy hitch and quick hitch of the 3pt arms. By having the weight so far back there is a bit of a multiplier to the weight compared to case iron wheel weights or other weight. I get that the 3pt arms are spendy. I think I saw something about a 3rd party option out there. Never looked at it because I have the John Deere ones. If you are thinking of going FEL with that machine you will need some solution for ballast on the back. The front axle can't take the load.

I was originally looking for a 45 series but they went out of production and just were not coming up so we went CTC.

Since you like pics here are a few.

This is from this weekend when I got a load of mulch.
