Spray rig I made under $100

Postby Ol Timey Farming LLC » Mon Dec 02, 2019 12:17 pm

I was given an old 40 gallon spray rig that my neighbor thought was broken. He said I could have it as he replaced the electric pump after the original one burnt up. But he didn't install the new one correctly (intake hose wasn't tight so it sucked air and wasn't building pressure well). So he said I could have it if I could fix it. Well after finding the problem (tightened all fittings/hoses) it worked. Next was to make something to carry it behind my tractor and spray crops with (added a boomless sprayer nozzel, 20' spray). I have 4' wide beds, both my cub and SA have over 4' space between tires and over 14" of crop clearance SO I had to make sure my trailer could also do the same. It has almost 15" clearance and tires are over 4'3" apart. Here are my original plans and actual finished rig. Though it will be spring before I can test it by fire. But initial hand pulling and test showed it should work fine. (Note, I added extra caster wheels after thinking about having close to 400 lbs. on only 2-10" caster wheels) So I made duals to help keep it floating on soil.

I bought the wheels from Harbor Freight (10") for $3.99 ea (x4)
Bought 4 treated 2x4x8' about $5 ea and 1 treated 1x6x10', 5/8 all-thread (axles) and 8 washers, 6 lock-nuts and 2 regular 5/8 nuts all for around $20) from Lowe's (call around you may find it cheaper)
The boomless sprayer nozzle was $25 at a local feed store.

I plan on using this sprayer to spray my crops with Suma-Grow (has beneficial microbes and humic acid)(helps soil) and compost tea (put about 1 gallon of compost in an old pillow case and steep in water for 48 hrs, I also add a fish tank air bubbler to help the good microbes to multiply-they need air to flurish) I put this pillow case in a 5 gallon bucket and fill it with water. After 2 days (48 hrs) I then add this water to my sprayer and add the suma-grow and fill the rest with water. I spray about 40 gallons to the acre. I also let the used compost dry some and add it as a side dressing to any stressed plants. Hope this gives some here some ideas and helped someone...

I would think that thing would get destroyed with a few short uses...that frame is made of wood!!

For about $60 on sale I think it was I bought a 24 gallon boomless spray unit new. And you don't have the fabrication time involved. But I do think it's good to make stuff out of thrown away or unused stuff.

I like it , I have used more of those wheels than I can count at this point, only bad thing is they stink something terrible when they are new, don't leave them in the cab of the pickup like I did, it smells like a skunk mixed with burning rubber! TJ

If it does then I'll build a metal frame to hold the tank. But that 24 gallon rig you have can't fit over crops, I know it wouldn't clear 15" like mine. It also probably (need pictures to know for sure) but probably doesn't have over 4' wide axle to clear my 4' wide beds either. So its good for your use but to put fertilizer and humic acid along with beneficial microbes on the crops I need the trailer to be wide AND tall. 40 gallons of water is 340 lbs, even with fert and weight of trailer I'm sure it weighs under 450 lbs. Treated 2x4's hold up your house and carry over 450 lbs loads so I think as long as I don't sink the wheels in wet loose ground and still pull hard it should last. There are wagons from the 1800's that are still used today that carried way heavier loads and lasted hundreds of years. If this lasts just a few seasons and makes more crops it did its job. But I did also say I'll see this spring 'IF" it will work like I think (tested by fire). I'll test it under harsh conditions then and will see if it works as planned. You may be right BUT I think it should last being treated and I added extra cross supports and used good screw fasteners instead of nails. This will also allow me to easily remove a board and just re-screw in a new one IF something does break. But lets hope it doesn't for quite some time. I'll re-post after spring and show the good, bad n ugly sides this spring.

1 thumb up for the innovation and 2 thumbs up for spraying organic compost tea! :beer:

Chris

I like how it is as wide as the Cub so you can trail in the tractor's tracks. Will be looking to do something similar so this is good to see. Will have to check out harbor freight to look at wheels, never been to one and there is one maybe 15 miles away. Good tip. And will check out "Suma Grow". Thank you for posting your plans & ideas and sharing your cost breakdown. Let's see it working in the spring!!!

Your right my rig won't clear 15" crops. But that's only because it's mounted on my ATV. Build a little platform on the back of the Cub maybe a rear lift carryall like three point tractors can attach and mount it there and wherever the tractor goes so does the sprayer.

And I agree wood is strong. Very strong. I just was looking at the weight of the water and possibly twisting forces that would be exerted being pulled off road on that system is why I say it might not hold up.

I originally had just a platform that was held onto drawbar (My cubs and Super A don't have 3 point OR 1 point hitches). The drawbar plan didn't work well as it couldn't be centered as the tank then hits the PTO and pulley. Because of the offset I would have had to make it permanent not just an add on implement because the offset put over 80% of the weight over a foot off center of the drawbar (not including sloshing forces when stopping or going). BUT I need the drawbars for other implements like my manure spreader, my cub 1 bottom wing plow, my 2 row pull type disk harrow, my A-295 2 bottom wing super chief plow, my tooth harrow and my modified bush-hog that mounts on drawbar (6' on the SA-and its all it can handle). I also agree with you that it can't go fast nor in really bad areas. The reason I put duals on it was in hope that those small tires don't sink (better flotation) in soft ground and the single tires try acting like a chisel plow LOL. I looked at other wheels BUT true flotation tires and rims (not even counting axles for them) cost hundreds of dollars. So I'm seeing if this will work. It may be great, or it may be a failure. I'll post either conclusion and what I plan next IF plan "B" (plan "A" was the drawbar idea) doesn't work.

If the high clearance cart doesn't work out. How about something mounted to the front. Maybe from the front bolster where the snow blade would attach and reaching forward attaching under or over front axle. Could be wood or metal angle iron. You would be able to keep an eye on everything. Only drawback I see could possible be the weight. Just a couple of thoughts. Maybe plan C? Good luck. Walter

I love the creativity! Solving the challenges presented with what is available.
Can't wait to see it spraying in the spring!
In the meantime, tell or show us how you are powering this rig. (12v Tractor, Pony Battery, Remote switch)

On my spray rig, I used a cigarette lighter socket so that if the rig came unhooked from the tractor, the wiring would just pull out without damaging anything. Over time, the socket has rusted a bit and is a little fussy, but does do the job needed. I added a switch on the dashboard to turn on and off the cigarette lighter. I see that Countryline now has a key fob remote to turn on and off sprayers. (found at TSC) wish I had used that instead of the switch.
