21-Gallon Tow-Behind Boom/Spot Sprayer, 2.2 GPM, 12V, 70 PSI

I've ran this for 5 tanks now. It's a good sprayer for your yard. I like the product itself. The recirculation part is a major plus as it keeps the chemical mixed up. I run the pump during filling to throughly mix the chemicals. The booms work good. The wand? Cheap. I don't like the wand, I'll be replacing it soon. My real complaint? The nuts and bolts sent with it. I was missing 4 bolts, couple of washers. Which, during assembly? Yup. Run to the hardware store. Other's have complained about it leaking out of the box. Tighten the clamps, good grief, how hard is that? The hose leading from the pump to the booms was too short. I cut a piece from the wand hose and fixed that. One of the clamps on a boom arm was loose, but the screw head on the clamp was too the inside of the boom arm. I had to cut the zip tie, loosen and rotate the clamp, then tighten and replace the zip tie. All in all, with a hardware store 10 minutes from me, the missing parts added about an hour to the assembly. Other than the missing parts and the clamp problem? I'm happy with the unit. I love the recirculating feature as it keeps the mix, mixed up. I will completely replace the wiring. That's not a issue with the sprayer as they have to do what is needed to fit many different applications. Just saying so you are ready to replace the wiring from your lawn mower to the pump. I'm going to replace the on off switch with a rocker switch plus hard wire it to the battery. My preference. I'll be using my sprayer a lot so I need a dedicated wiring solution. The wand? I'll be replacing it soon. The wand works, yes. Do I like the wand? No. I'm still giving it a 5 star rating. I like this sprayer and am happy that I bought it. When it comes to something like this? You will never have a (one size fits all) kind of system. Too many variables for the manufacturer. So. All in all? I like the sprayer. Would recommend it.

Took about 1 leisurely hour to put it together. I was short some of the 5/16 bolts and nuts, but fortunately had spares in my junk box. Directions were OK, but bolt shortage caused me to have to re-assemble the chassis. Axel washers were not packaged with other hardware but strung over the wand. I have 40 acres of forest in the western Sierra and am working to make it healthier, removing ground and ladder fuels. I have used this sprayer for just about 6 hours now, dispersing six 30-gallon loads. It really puts the herbicide out there. The 2-head spray manifold is a bit flimsy but works well and stows nicely for storage, The swath is actually more like 9 ft. I was pulling it behind my Suburban, 4WD over modest terrain. The wheels are a bit small for the forest floor but fine for yard work, bushings rather than bearings, but with a grease Zerk. The wand is all plastic fittings, rather leaky, but works. The wand hose was somewhat short for my application. The pump seems pretty robust. I powered it independently with a 20 Amp-Hr LiFePO4 battery, which only had to be recharged about a 30 minutes during the 6 hrs. Plan to replace the wand with brass, add a wand hose extension, possibly retrofit with 16" tires (will require raising the tank), and pull it with a 4WD Quad (or maybe retrofit to mount to the quad rack.) Will provide a 6-month update.

My 40 year old sprayer bit the dust one last time and it wasn't cost effective to replace the aged rubber hoses and install a second pump, not to mention the pneumatic tires after 40 years had dry rotted to pieces. This little sprayer seemed a good option to try, even knowing that it won't likely give me the same life of performance but hey, I'll probably be dead before I can say "I told you so" in another 40 years. Biggest beef: Include the dang instructions for us old farts. What did the company save, like a dollar? Instead they include a QR code and you have to scroll through dozens of products to download a pdf that is freaking hard to read on a phone. So I lost a day until I could get it transferred and printed to take to the shop where the pieces lay strewn on the floor (always keep a grandkid or two around for your tech support with getting the instructions). Having said all that, I confess I lied and like any good man already started assembly without the instructions ofc. Advantages. The boom arms are spring hinged so if you whack a bush, they will fold out of the way rather than ripping off the tank or some other horrendous casualty. This tank has a drain (my old one did not which was a pain in the rump to flip it up end just to clean. And for winter storage, this is designed to hang from a wall hook in the barn (+++). Tank attachment holes lined up well with the trailer support holes. Annoyances. Plastic spray nozzles, barbs and valves. Got it, its the way of production today but they'll probably not last a couple years. For me, I harvested the brass nozzles from the old sprayer when things were built durable. Brass barbs and mini valves would be highly recommended (available at the hardware or Amazon) for anyone that wants to better ensure lasting performance. The tank 'lid' screws in and at first did not want to thread straight. Set your sprayer in the sun for a little while then try again, pressing down squarely to screw in. The cold plastic tank may have been a little distorted and much easier to 'fix' with the sun trick. One reviewer complained about the hitch but from the pics it look like it was assembled wrong. When assembled correctly and driven at sane speeds, I found no issues with the hitch so far. Don't forget to put the gasket in the drain cap before screwing it on. Actually mine still leaked because the gasket was cut. Easy, easy fix; a garden hose gasket fit right in and sealed the bugger up tight with no dribbles. Also check tight any preinstalled hose clamps; mine were loose and would have immediately leaked. Wiring comes with battery clamps and an inline switch. I promptly cut that off and replaced with an auto connector to match the aux wire on the tractor which I control with my LED missile control firing switch installed on the tractor instrument panel. Final assembly shown in the pics. Towing is adjustable in height to adapt to one of my garden tractors or to the ATV.

This product arrived as promised from Amazon. I took about 45 minutes to assemble and i only had a couple small issues. The suction elbow would not go in by pressing and turning as stated in the manual. I had to use a C clamp to press it in. Also one of the wand clips was broken out of the box. I will contact Norther Tool for a replacement. After assembling I filled it with a bottle of Dawn dish soap and 31 gallons of water. The blue color of the dish soap helped to be able to see the level while on thee tractor and dish soap also helps relieve the surface tension of the lawn. I have an acre of property and the application chart in the manual indicates that at 35# pressure, 31 gallons of liquid when moving at 4 miles per hour should cover an acre. There is a speed chart in the manual that describes the distance you should travel in a prescribed time period to calculate your MPH. This came in handy because i do not have a speedometer on my tractor. I tried to maintain a constant speed and after using the booms and the wand to cover the areas I could not reach with the boom I had about 2 gallons left over. During this test run I had no leaks, the booms operated as advertised, the wand worked well, the pump worked well performed flawlessly and cleanup was a breeze. When thing go this smoothly you are on your way to believing that you made a sound purchase. I am one happy camper. Thank You Amazon and Northern Tool! Debra's Hubby

I was a little skeptical about purchasing this product, but I am glad I did. I debated between the 21 gallon and the 31 gallon sprayer and am glad I went bigger for the extra $20. The hand sprayer works much better than I expected with the variable spray pattern, and when I want to dose the plant with water I take the end off and use it as a garden hose. The 2.2gpm pump is a perfect match for the tank. The only issue I had when assembling this is the hoses for the boom weren't quite the correct length, and the clamps weren't quite tight enough for a leak free fitting, but those were easy fixes. I did make a couple of modifications for easier use though. I cut the 3/8" hose and added a couple garden hose ends about 6 inches behind the hand wand, then installed quick connects so I can easily and quickly go from the hand wand to a garden hose. The other modification I did was snipping off the battery clamps and replaced those with an automotive type plug in connector that's weatherproof (metripak 20 series). This eliminates the worry of the clamps falling off or grounding out on the tractor frame. The only thing I am in need of is a watering head that can deliver a gentle like rain shower for watering rather than the supply spray nozzle, when is a little harsh for everyday watering, and it's hard to find a 3/8" diameter watering wand so the pump can deliver enough pressure. My quest for this will continue, and when I find something that will work, I will share. I'll take a photo of the electrical connector later and upload it to the review if I can. As for the boom, it works ok but won't be my go-to. The pattern seems to work as advertised, will just take quite a few passes in my option to achieve the desired results. Maybe this is good for a smaller yard rather than acres. Overall, a very nice product and I would recommend it for a purchase. Northern Equipment has great products and great customer service. Will buy again from them.

Updated May 2025: the wand handle did not survive the winter here in southern Virginia. Went to use the tank, and the wand sprayed liquid everywhere along the seam on the plastic handle. There is no shut off for the handheld sprayer hose, unlike the two rear mounted sprayer nozzles. So I found a replacement wand. My fault I suppose for leaving the tank under the barn lean to all winter - although it was drained and dry. Be sure you winterize and keep your sprayer someplace warm! Original review: Got this for insecticide and watering our property. It was relatively easy to assemble, although some of the bolts were difficult to thread into their threaded inserts. Just had to be patient and just barely start the threads. Afterward using it has been very easy, and solved the issue of watering during a drought. Highly recommend.

It's a piece of junk. First, no assembly instructions. They do provide a QR code that takes you to an absolute joke of a website that lists ALL their products on one page. One as to scroll a LONG way down to find this one. They could've easily categorized their products in order to find the manual. Second, once manual is downloaded it makes it very clear to make sure the version of the manual matches the version of the unit. Their manual is version G and my unit is version H. I don't know what the difference is between the versions. Third, parts were missing from the box. Thankfully, they are just the axle washers, so I'm able to assemble this without them and I'll contact them later. Third, after fixing all the leaks at the hose connections, I wasn't able to fix the leaks at the boom spray nozzle. They provided no type of rubber seal. I had to go to the hardware store to purchase o-rings to stop the nozzles from leaking. Overall, the manufacturer is a joke and would not recommend buying anything from them. I haven't used it yet, but from the other reviews I've read I'm not thinking it's going to last very long before it quits working.

I read other reviews, was concerned about the product condition on arrival. Upon arrival, just like other reviews, the box was damaged and retaped. looked like a return. When fed ex brought it in my garage I could hear all the parts loose in the box. I opened it before delivery left. All loose parts were in the sprayer container. Pump box was damaged and the end of the pump was damaged but serviceable. Put it together in 2 hours, filled it with water and it worked perfect. Sprayed almost 10 feet wide. It arrived 2 days early and no parts missing or left over. Great YouTube video was easy to follow.

I had an issue with a part that was broken, I assume, in transit. Left a message on Amazon and Farol called back within 2 hours and confirmed replacement part would be sent. Great little sprayer, good overall quality, although nozzles tend to drip. Easy to assemble, just take care to follow the correct model as there are two different models covered in the assembly instructions
