  • Good yard sprayer
Size: 31 Gallon
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. ... show more

  • Gerat Product and Customer Service
Size: 31 Gallon
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. ... show more

  • Excellent Sprayer, Mediocre Wand
Size: 31 Gallon
I have a good size properly that I would treat with a regular pump sprayer, so I was debating between a backpack sprayer and a tow-behind. Ultimately, I need to treat about an acre of lawn as well as repetitive weed intrusion from the edges of the woods that border 3 sides of the property, so I felt a tow-behind was better. Assembly was easy and took about 30 mins. Instructions were pretty clear, however as others have pointed out, some steps were a little confusing since they use the same book for 3 models. You just need to pay attention to which model you have and which instructions apply. There were only on about 3 steps that might trip you up, but it could be clearer. It is nice they include torque specs for the bolts/screws. As others have mentioned, I did need to tighten up some of the hose clamps to prevent leaking. It's very sturdy - well made. I have the 31-gallon unit, and it's stable on hills as well. The booms work really well. They are spring loaded to "break away" if you hit something while towing it, and they collapse down for storage. There are also instructions on winterizing and breaking it down to store it from a wall peg. Very helpful. Spray coverage is quite good. It took a few passes to get used to speed so I get adequate coverage. I think I was running about mid-throttle for a good coverage. The downside is the handheld spray gun. It's terrible. It worked fine for a first pass with Roundup on woods edge weed intrusion, but a few days later I was doing a lawn weed spray and needed to hit some areas with the wand. It started leaking. Tightened it up, but it still leaks from the valve. It's junk. I already ordered a better replacement for about $28 here on Amazon. There are a few drawbacks to keep in mind. This is a tow-behind unit, which means you need to be able to get it to where you want to spray. Because of that, there are some places where it could be difficult to use. I have some areas I can't get the tractor into, so I need to use a regular hand-pump sprayer for those (wand won't reach). And driving the tractor with the wand in your hand is hard due to the hose - kind of like vacuuming while trying not to run over the cord. But, overall it was a huge time saver. I did the entire lawn in about 30 mins, and it would have taken 4-6 hours by hand with a backpack sprayer and I can't realistically reach much of the lawn with hose-based sprayers. This thing definitely made a big improvement. I plan to also spray for ticks and such, so this will easily get multiple uses per year. ... show more

  • Gallon jug listed more then I needed BUT I forgot to read closer and see that it was listed for Southern grasses not Northern li
I am a Dandelion Mass Murderer. My only problem was running out of chemical and only having half what I needed. Gallon jug listed more then I needed BUT I forgot to read closer and see that it was listed for Southern grasses not Northern like where I live, which means double strength. The spray wand is a little awkard using fiber re-inforced hose which is stored by wrapping it too tightly around clamps up front. That leaves it wanting to be a coil even more then what that hard plastic wants to be normally. Draws a little under 6 amps (measured with my Fluke 75 multi-meter) on my John Deere X320 Lawn tractor, I saw no drop in voltage on the charging system when the power is engaged and the engine is running. From the factory the switch and harness hooks to the battery with the alligator clamps you expect to see on a motorcycle battery charger. Simple and effective. I may run it through my fused 12 volt adapter as the load is small enough and the fuse for that circuit is 10 or 15 amps. Set at 20 psi on the guage and running at 5 mph gives nice coverage. This is pretty much full out with the lawn tractor whose top speed is supposed to be 6 mph but it only shows 5 on my gps. If you've never pulled a sparyer before, get up early on a calm, dewy day and let your tracks guide you. Makes it easy. If you Don't get the chance and the winds are down, follow the tracks you've left by following the same pattern each and every time you've mowed the lawn. You know you do. The mount is a tad high for my lawn tractor, the lowest setting has it mostly level, I would have felt better with a little more play on the low side but this is designed to work behind a 4 wheeler and they have a higher attach point. Also, this is listed as a pesticide sprayer on the booklet. The instructions on how not to contaminate yourself are good and should still be followed with herbicide. The herbicide we mostly use here is Amine 24D. If you don't know what Agent Orange is, look it up. Granted it was Amine at a stregth to make this look like weak Tea but really you should limit your exposure to it as much as possible. Great product with listed parts online if you should ever need to replace something. ... show more

  • More efficient than tow-behind broadcast spreader, way moreso than a backpack sprayer.
Size: 31 Gallon
Overall, it's what you can expect for this price from a budget tool brand. It goes together well, tech support is great. The chassis, axle, wheels and tires, and the overall tank build seem very sturdy. Even the sprayer arms seem decent; they do fold back if you accidentally crash them into something. The rest of the parts are a little less sturdy, but are all wear parts. Hoses of this kind will need replacement after a few years, fittings are plastic will fail as well. The pump and is obviously the most sophisticated part of the product. The electric motor half of the pump is low budget, but it's only an electric motor, they are not very complicated. The pumphead half is low budget as well, all plastic. The internal rubber diaphrams are wear parts as well, and will need to be replaced after a few seasons, and won't last one season if left with any water inside overwinter. I will definitely cycle some antifreeze into the system over winter. The regulator is all plastic as well. My regulator came from the factory with the pressure gauge way overtightened and so overloaded with white teflon tape that the fitting was flared out and leaked out of the box. To solve that leak, back it out carefully, clean away all the old tape from the gauge and the inside of the regulator body, add new teflon to the gauge, and hand tighten it. Only three wraps of tape. Don't gob it on there like they did at the factory. I also had leaks out of the box at the sprayer nozzles. For this you want to grab a couple of 1/2 inch black o-rings from the hardware store and use them behind the nozzles. I also had a leak at the drain cap, which is poorly formed and weak, this too benefit from some wraps of teflon tape. The red knob is a pressure adjustment, that works by opening the suction up to some air. If your pump turns on but does not start, first check for a vacuum leak on the intake side of the pump by making sure the hose tensioners are snuggly screwed and that the hoses are not broken anywhere. The hose tensioners are cheap as well, and easy to overtighten, which damages the tensioner. If there is no vacuum leak, the pump needs to be primed. Do that by removing the hose from the intake straw and then sticking the intake hose right inside of your garden hose to blast some water up there into the pump. Gets great coverage and has made my lawn and garden applications a stress free and fast process. 31 gallons is plenty of juice for my lot, which is about 30,000 square feet of lawn. Had to fill a backpack sprayer four to six times for good coverage. Very easy now to spray my grape vines and fruit trees as well. Edit: checking in after one year, this spreader has held up very well. The hand sprayer cracked over the winter, obviously there was still some fluid somewhere in the handle that I failed to drain. I replaced it with a metal hand sprayer. Otherwise, I have zero complaints. ... show more

  • NOT RECOMMENDED
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. ... show more

Unit is as advertised, however after setting up pump would come on but not pump. It uses as diaphragm pump which is fine for this style system. Removed head found one screw was loose, inspected and it looked ok. put head back on and pump worked. I suspect it was drawing air from loose screw. Housing of pump is not metal but all plastic. Also leaked from drain cap. There was no gasket in cap, installed hose pipe gasket and now does not leak. First use was good and it performed to task. I wish they would have done a little better on quality control as most customers would have had to return. ... show more

  • Great buy
First let's start with me being a little sceptical after reading some of the reviews concerning assembly and poor instructions. After getting my 21 gal sprayer I took everything out of the box and layed out all of the parts. Everything was there except one item. Then I realized the instructions were for 2 sprayers and the part I was missing was for the other sprayer. Problem solved. Assembly was pretty straightforward and everything went right together. I did have to adjust one of the plates where the axle went through to make it spin a little easier but other than that, pretty easy. I did tighten up all of the hose clamps during assembly. I filled the tank with about 6 gal of water to test for leaks and to adjust the tank pressure for the spray. No leaks and it puts out a nice even spray. I have a 1/2 acre lot in a rural farm area and have a lot is weeds and puncturevine. I found the use of the sprayer to be very easy and the on/ off switch to be very convenient. Now I just have to let the herbacide do its job and probably respray in about 2 weeks to catch the stuff I missed. Good purchase. Just read the instructions and don't overthink it. It's simple and straight forward. Yes the hoses will leak if you don't tighten them. Do it during assembly. I would definitely recommend this product. ... show more
