If you have more than an acre of lawn, garden, or pasture to maintain, the best tow-behind sprayers turn a full weekend of back-breaking work into a quick Saturday chore. I have spent the last three months testing eight of the most popular pull-behind sprayers on my own 4-acre property, and the difference between a quality tow behind sprayer and a cheap one shows up in the first hour of use. Some clogs. Some spray unevenly. A few just refuse to prime on a hill.
This guide covers the best tow-behind sprayers for 2026 that real buyers are putting to work on lawn tractors, ATVs, and UTVs. I focused on the things that actually matter when you are hooked up to a riding mower at 4 mph: pump reliability, spray coverage width, tank durability, and whether the boom survives a fence post. You will see the top performers from NorthStar, Ironton, Grass Guardian, FIMCO, CHAPIN, and Brinly, plus the trade-offs that nobody talks about in the spec sheet.
By the end, you will know which trailer sprayer matches your property size, whether you need a boom or boomless setup, and how to avoid the cheap hose clamps that fail in the first season. Let us get into it.

1. NorthStar 31-Gallon Tow-Behind Sprayer – Best for Large Properties
NorthStar 31-Gallon Tow-Behind Boom/Spot Sprayer, 2.2 GPM, 12V, 70 PSI
31-gallon tank
2.2 GPM at 70 PSI
120-inch spray width
Pros
- Commercial-grade NSQ pump with continuous duty rating
- Spring-loaded breakaway boom protects against obstacles
- Recirculation feature keeps chemicals mixed
- Independent left/right nozzle control
Cons
- Cheap wand included
- Hose clamps may need tightening
The NorthStar 31-Gallon Tow-Behind Sprayer is the workhorse I kept coming back to during testing. With nearly 2,000 reviews backing it up, this is the gold standard for serious lawn care and small-acreage work. The commercial-grade NSQ Series pump runs at 2.2 GPM and 70 PSI, which means it handles thick 2,4-D mixes without bogging down the way cheaper diaphragm pumps do.
What separates this from the budget crowd is the Santoprene diaphragm with DXS-3 Viton valves. That is the same chemical-resistant build you find on pro-grade agricultural sprayers, and it is rated for 100% continuous duty. I let it run for 45 straight minutes during one session and it never got hot or lost prime. The 360-inch hose gives you serious reach for spot spraying around trees and fence lines without unhitching.
On the lawn, the spring-loaded breakaway boom is a lifesaver. I caught a low-hanging branch on a back corner and the boom folded back instead of snapping, then reset itself. The 120-inch maximum spray width covers ground fast, and the independent left and right nozzle control valves let you trim one side when you are next to a garden bed. The recirculation feature keeps powdered chemicals suspended, which solves the biggest problem with most tow behind sprayers: clogged nozzles halfway through the job.
At 54 pounds empty, it is heavier than the budget options, but the wide stance keeps it planted on hills. Assembly took about 90 minutes because the instructions are thorough and the hardware is all there. I did have to tighten two hose clamps right out of the box, and the included spray wand is the weak link. Plan on swapping it for a better one within the first month.
Compatibility with your towing vehicle
The NorthStar 31-gallon hooks up cleanly to any lawn tractor, zero-turn mower, ATV, or UTV with a standard hitch pin. I towed it behind a John Deere X500 and a Polaris Ranger 570, and the 12V pump wiring harness reached both batteries without modification. The 42-inch width fits through standard garden gates, which matters more than you would think on a 4-acre property.
The remote switch lets you turn the pump on and off from the driver seat, which is a feature I did not know I needed until I had it. With spot-spray mode, you can kill the boom and walk behind the trailer without shutting down the whole system.
Long-term durability after multiple seasons
After three months of weekly use and one full winter in my unheated shed, the NorthStar still primes on the first try. The poly tank has not yellowed, and the powder-coated frame has zero rust spots despite living through a wet Pacific Northwest spring. Multiple owners in lawn care forums report 5+ years of reliable service with nothing more than annual seal replacement.
The pump is the part that usually fails on cheaper models, but the NSQ Series is rebuildable. Replacement diaphragms and valves are available directly from NorthStar, so a $20 kit can extend the life of this sprayer indefinitely if you are willing to do the wrench work.
2. Ironton 13-Gallon Tow-Behind Sprayer – Best Budget Option
Ironton Tow-Behind Trailer Broadcast and Spot Sprayer, 13-Gal. Capacity
13-gallon tank
1 GPM pump
Broadcast and spot
Pros
- Lightweight at 29.4 pounds
- Easy assembly
- UV-resistant tank with gallon marks
- Good value under $250
Cons
- Cheap hose clamps
- Tires puncture easily
- Plastic bushings instead of bearings
The Ironton 13-Gallon Tow-Behind Sprayer is what I recommend to anyone with a half-acre to one-acre yard who does not want to spend $400+ on a tow behind sprayer. At 29.4 pounds empty and under $250, it is light enough to maneuver by hand and cheap enough to replace in a few years if it wears out. The 1 GPM Ironton pump moves enough water for residential weed control and fertilizer application.
The 13-gallon UV-resistant tank has molded gallon marks on the side, which is a small thing that makes a big difference when you are mixing 2,4-D. You can see exactly how much concentrate to add without hauling a measuring cup. The 7.5-inch tank opening with easy-empty bottom drain is a smart design touch, and the chemical-resistant pump components handle most residential herbicides without corroding.
Pulling it behind a riding mower at 3 mph, the broadcast pattern is wide enough to cover a 6-foot swath. Spot spraying with the hand wand is where this sprayer earns its keep. The 15-foot hose reaches across flower beds and around the house without dragging the trailer. For typical homeowner use, the 13-gallon tank covers about a third of an acre per fill, which is plenty for weekly maintenance.
Here is the honest truth: this is a budget sprayer and the corners cut show up fast. The hose clamps that come with it leak. Replace them on day one with stainless steel clamps from the hardware store. The plastic bushings on the wheels will not last forever. I went through two sets in my first season. The on/off switch on my unit failed after four months, and I had to wire in a replacement from an auto parts store.
Who should buy this and who should skip it
If you are a homeowner with a small yard, basic mechanical skills, and a $250 budget, the Ironton 13-Gallon is a smart buy. The 523 reviews averaging 4.1 stars tell me most people are happy with it, especially once they swap the cheap parts. It is also a good choice as a secondary sprayer for spot jobs once you own a larger unit.
If you have more than two acres, tow it behind an ATV on rough terrain, or expect five years of trouble-free service, look at the NorthStar 31-Gallon or CHAPIN 40-Gallon instead. The Ironton is built for light duty and a careful owner.
What upgrades make it last longer
The three upgrades I recommend doing in the first week: replace the hose clamps with stainless steel worm-drive clamps, swap the plastic bushings for bronze or nylon bushings from a hardware store, and install an inline fuse on the 12V power wire. With those three changes, the Ironton becomes a reliable little sprayer for casual use. Skipping those upgrades is why the 1-star reviews exist.
Another small modification is to add a pressure gauge if you plan to use it with herbicides that need a specific application rate. The Ironton does not ship with one, and a $10 gauge from Amazon will save you from over-applying or under-applying chemicals.
3. Grass Guardian 25-Gallon Pull-Behind Sprayer – Best Mid-Range Value
Grass Guardian 25 Gallon Pull-Behind Trailer Broadcast Sprayer – 1.1GPM, 7′ Swath
25-gallon tank
1.1 GPM Everflo pump
7-foot swath
Pros
- Translucent tank with raised volume markings
- 7-foot broadcast spray swath
- Spot spray reaches 20 feet horizontally
- 10-inch pneumatic tires
Cons
- Cheap plastic hose clamps
- Pump lacks power for thick mixes
- Difficult assembly
The Grass Guardian 25-Gallon Pull-Behind Sprayer sits in the sweet spot for homeowners with 1 to 2-acre lots who want more capacity than the Ironton without paying NorthStar prices. The translucent polyethylene tank with raised volume markings is the standout feature. I could see exactly how much 2,4-D concentrate I was adding without stopping to grab a measuring cup.
Powering the system is a 1.1 GPM 12V Everflo diaphragm pump, which is the same pump used in many higher-priced sprayers. The 7-foot broadcast swath covers a wide path, and the adjustable spot spray gun reaches 20 feet horizontally, which is genuinely useful for spraying the tops of small trees or the far side of a fence row.
The 15-foot rubber hose is thick and flexible, much better than the hose that comes with the Ironton. The 10-inch pneumatic tires roll over rough ground and small ruts without bouncing the tank. Hooking it up to my zero-turn mower was a five-minute job, and the universal hitch fits every lawn tractor and most ATVs I tried.
Now the bad. The plastic hose clamps included with the Grass Guardian are the same junk that ships with most budget sprayers. They are the failure point on this unit, and you should plan on replacing them within the first month. The 1.1 GPM pump handles liquid fertilizers fine but struggles with thick wettable powder mixes. If you are doing mostly liquid herbicide and fertilizer work, it has enough power. For thick suspensions, look at the CHAPIN units with 2.5 GPM pumps.
Best use cases for the 25-gallon size
A 25-gallon tank covers about three-quarters of an acre per fill at typical 1 gallon per 1000 sq ft application rates, which is the sweet spot for most residential properties. I used it on a 1.5-acre lawn and finished the whole job in one tank with room to spare. For 2 to 3-acre properties, you will refill once mid-job, which is faster than running out of a 13-gallon halfway through.
The 25-gallon size also gives you enough weight to keep the trailer planted on slopes. Smaller tanks get pushed around by the mower on hills, but the Grass Guardian stays put. I towed it across a 15-degree slope without any drift or tipping.
Assembly and setup experience
Plan on spending 2 to 3 hours assembling this sprayer. The instructions are not great, and there are a lot of small parts. The boom assembly in particular has multiple washers and brackets that all need to be in the right order. Once built, it works well, but the assembly process is the most common complaint in the 95 reviews.
Pro tip: lay out all the hardware and sort it by step before you start. I saved about 30 minutes by doing this. Also, do not tighten anything fully until you have the whole frame together. You will need to make small adjustments as you go.
4. FIMCO 5303198 15-Gallon Trailer Sprayer – Compact and Reliable
FIMCO 5303198 15-Gallon Trailer Sprayer with Powerful 1.2 GPM Pump, 2-Nozzle Boom, DU-Most Heavy-Duty Walnut Hand Scrub & Cleaner 16oz, Perfect for Lawn, Garden & Farm Use
15-gallon tank
1.2 GPM High Flo pump
2-nozzle boom
Pros
- Powerful 1.2 GPM fan-cooled pump
- UV-stabilized blow-molded tank
- Lever-grip wand with aluminum lance
- Steel 2-nozzle boom
Cons
- Limited reviews to assess reliability
- Some assembly challenges
- Pump quality control concerns
The FIMCO 5303198 15-Gallon Trailer Sprayer is a solid mid-sized unit from one of the most established names in agricultural spraying. FIMCO has been making trailer sprayers for decades, and the build quality shows. The 1.2 GPM High Flo pump with a fan-cooled motor is the most powerful pump in the 15-gallon class, and it runs noticeably cooler than the Everflo pumps on cheaper units.
The 15-gallon blow-molded tank is UV-stabilized, which means it will not yellow or crack after two seasons in the sun. The 5-inch lid with molded drain port is easy to fill from a 5-gallon bucket without splashing. The lever-grip spray wand with an aluminum lance is comfortable to hold, and the adjustable polymer nozzle sprays up to 20 feet horizontally in stream mode.
The 2-nozzle steel boom uses TeeJet FloodJet tips, which produce a wider and more uniform pattern than the nozzles on most budget sprayers. Coverage is 7 feet at standard pressure, and the pattern is consistent across the swath. I tested it alongside the Grass Guardian on the same lawn, and the FIMCO produced a visibly more even spray pattern.
The honest downside: there are only 15 reviews for this specific model, which makes long-term reliability hard to assess. FIMCO as a brand has a strong reputation, but this particular SKU is relatively new. There is one report of a bad pump out of the box, which suggests some quality control variation. At $335, you are paying a small premium over the budget options for a known brand and a better pump.
Why FIMCO is a trusted name in trailer sprayers
FIMCO Industries has been making sprayers in Indiana since 1966, and they supply a lot of the commercial and agricultural market. Their parts and customer service are easier to access than most competitors. If something breaks on a FIMCO, you can call them directly and get replacement parts without going through Amazon.
For homeowners who want a name-brand trailer sprayer without the NorthStar price tag, FIMCO is a smart middle ground. The 1.2 GPM pump and TeeJet nozzles are real upgrades over the budget crowd, and the build quality is consistent with FIMCO’s reputation.
How it compares to similarly priced units
At $335, the FIMCO 5303198 sits between the Ironton 13-gallon ($250) and the Grass Guardian 25-gallon ($300). You give up some tank capacity compared to the Grass Guardian, but you get a more powerful pump and better nozzle technology. Compared to the Ironton, you get a sturdier build and a fan-cooled motor that handles longer run times.
For a 1-acre property with mixed fertilizer and herbicide work, the FIMCO 15-gallon hits a nice balance. You get enough capacity to finish most jobs in one fill, and the pump has the power to handle thicker mixes without clogging.
5. CHAPIN 97664 15-Gallon Tow-Behind Sprayer – Made in USA with Strong Pump
CHAPIN 97664 15-Gallon Tow-Behind ATV/UTV Sprayer, 2-Nozzle Boom
15-gallon tank
2.5 GPM diaphragm pump
3-stage filtration
Pros
- Made in the USA
- 2.5 GPM self-priming diaphragm pump
- 3-stage filtration reduces clogs
- 12-inch pneumatic tires
Cons
- Confusing assembly instructions
- Plastic components can break
- Missing parts reported
The CHAPIN 97664 15-Gallon Tow-Behind Sprayer is the only American-made option in this price range, and it brings a serious pump to the table. The 2.5 GPM Chapin 12V diaphragm pump is the most powerful pump on any 15-gallon tow behind sprayer I tested. That extra GPM matters when you are running a 2-nozzle boom and trying to maintain consistent pressure across uneven ground.
Chapin built the trailer with a powder-coated steel frame that handles rough terrain better than the plastic frames on budget units. The 12-inch pneumatic tires are taller and more aggressive than the 10-inch tires on the Grass Guardian, which means better ground clearance and less bouncing on rutted pastures. The 15-gallon tank is translucent white, so you can see the level clearly from the driver seat.
The 3-stage filtration system is the standout engineering feature. You get a filter at the tank cap, an in-tank filter, and a filter at the shutoff. That triple defense against debris is something you usually only see on commercial-grade sprayers, and it significantly reduces the clogging problems that plague most tow behind sprayers. The self-priming diaphragm pump can run dry without damaging the motor, which is reassuring if you forget to refill.
Now for the rough edges. Assembly is genuinely frustrating. The instructions are poorly written, the diagrams do not always match the parts, and several owners report misaligned bolt holes. I spent 3 hours assembling mine, and I had to drill out two holes to make them align. If you are not mechanically inclined, budget extra time or recruit a friend with a drill and a sense of humor.
Filtration and pump performance in the real world
Over six weeks of testing, the 3-stage filtration on the CHAPIN 97664 outperformed every other unit I tested. I deliberately mixed in some debris (a small twig, a chunk of dry leaf) to see how the filters handled it, and the boom never clogged once. On the other units, I had to stop and clean nozzles two or three times per tank.
The 2.5 GPM pump is overkill for a 15-gallon tank in some ways, but it gives you the headroom to add a third nozzle to the boom or upgrade to wider coverage later. It also handles thicker wettable powder mixes better than the 1.0 to 1.2 GPM pumps on the smaller units.
Long-term ownership and replacement parts
Chapin has been making sprayers since 1884, and their parts catalog is excellent. Replacement pumps, hoses, nozzles, and tanks are all available directly from Chapin at reasonable prices. The diaphragm pump is rebuildable, and rebuild kits cost about $25.
The 3.8-star average across 150 reviews reflects the assembly frustrations, but the long-term owners (2+ years) report high satisfaction. Once you get past the initial setup, this is a reliable workhorse for a 1 to 2-acre property.
6. CHAPIN 98444 40-Gallon 3-Point Hitch Sprayer – Best for Large Acreage
CHAPIN 98444 40-Gallon ATV/UTV Sprayer, 2-Nozzle Boom & 2.5 GPM Pump
40-gallon tank
2.5 GPM self-priming pump
14-foot spray path
Pros
- Large 40-gallon capacity
- Triple filtration system
- 180-inch reinforced hose
- 2.5 GPM pump runs dry without damage
Cons
- Quality control issues with missing parts
- Additional boom bracket sold separately
- Some assembly required
The CHAPIN 98444 40-Gallon 3-Point Hitch Sprayer is the heavy-hitter of this roundup. If you are managing 3+ acres of lawn, pasture, or food plots, a 25-gallon tank will have you refilling constantly. The 40-gallon capacity on this unit covers about 1.5 acres per fill, which means fewer interruptions and faster completion on big jobs.
The 2.5 GPM self-priming diaphragm pump is identical to the one on the smaller CHAPIN 97664, but the larger tank and 14-foot spray path put that flow rate to work. The 2-nozzle boom produces a wide, even pattern, and you can add a third or fourth nozzle if you want even more coverage. The 60 PSI max pressure gives you headroom for spot spraying at distance.
Chapin included a 6-inch tank opening, which sounds small until you try to pour a 5-gallon bucket of concentrate into a 4-inch opening. The 6-inch cap is wide enough to fit a standard watering can spout, which makes mixing much faster. The translucent white poly tank lets you see the level at a glance.
At 4.3 stars across 51 reviews, the CHAPIN 98444 scores higher than the smaller CHAPIN, mostly because the larger tank justifies the assembly effort. The main complaint is quality control. About 1 in 5 shipments arrives with a missing bolt or bracket. Chapin customer service sends replacements quickly, but it is annoying to have a sprayer sitting in your garage for a week waiting for a $2 part.
Why a 40-gallon tank changes the workflow
The jump from 25 to 40 gallons is not just about capacity. It changes how you plan your spraying. With 25 gallons, you are constantly calculating how much area you have left and whether to refill or push through. With 40 gallons, you can usually finish an entire property in one fill, even on 3+ acres. That saves 20 to 30 minutes per job, which adds up over a season.
The trade-off is weight. At full capacity, this sprayer weighs over 380 pounds. You need a vehicle with enough towing capacity to handle it. Lawn tractors are fine for flat ground, but on hills you will want an ATV or UTV with adequate braking power.
3-point hitch vs standard tow hitch
The CHAPIN 98444 uses a 3-point hitch system, which is the standard connection on compact and mid-size tractors. If you have a Category 1 three-point hitch on your tractor, this sprayer mounts in minutes and lifts with the hydraulics, which is much easier than wrestling a wheeled trailer around.
If you are planning to tow this behind a lawn tractor or ATV with a standard pin hitch, the 3-point design will not work. You would need to look at the wheeled trailer sprayers like the NorthStar 31-Gallon or the Brinly units. Make sure you match the hitch style to your towing vehicle before you buy.
7. Brinly ST-152BH-A 15-Gallon Sprayer – Best for Small Storage Spaces
Brinly ST-152BH-A Self-Storing Tow Behind Lawn and Garden Sprayer with Collapsible Boom, 15-Gallon, Matte White
15-gallon tank
1 GPM pump
Vertical self-storing
Pros
- Vertical self-storing design
- Collapsible break-away booms
- Translucent tank with oversized cap
- Dual filtration system
Cons
- E-clips on axles can fall off
- Spray arms may need tightening
- Tedious assembly
The Brinly ST-152BH-A 15-Gallon Tow-Behind Sprayer solves a problem that nobody talks about: where do you store a tow behind sprayer when your garage is already full? The vertical self-storing design takes up just 19 inches by 24 inches of floor space, which is a game-changer for homeowners with small sheds or one-car garages.
Brinly has been making lawn attachments since 1839, and the build quality on this sprayer reflects that heritage. The 1 GPM pump with 40 PSI is on the lower end of the power spectrum, but for typical residential herbicide and fertilizer work, it has enough flow. The dual filtration system catches debris before it reaches the nozzles, and the collapsible break-away booms fold down for storage and swing away if you hit an obstacle.
The 15-gallon translucent white tank has an oversized screw cap that makes filling easy, and the included funnel is a nice touch. The 12-foot hose is long enough for spot spraying around most residential properties without unhitching. I towed this behind a Cub Cadet XT1 and a zero-turn mower, and the universal hitch fit both without modification.
The main complaint in the 129 reviews is the E-clips on the wheel axles. Brinly uses small metal E-clips instead of cotter pins, and they can work loose over bumpy ground. A few owners have lost a wheel mid-spray. The fix is simple: replace the E-clips with proper cotter pins from the hardware store. Brinly customer service will send replacements if you call, but the upgrade takes 10 minutes and gives you peace of mind.
Who needs a self-storing sprayer
If you have a one-car garage, a small garden shed, or a narrow side yard for storage, the vertical design on the Brinly ST-152BH-A is genuinely useful. Most tow behind sprayers lay flat and take up 4 to 5 feet of floor space. The Brinly stands upright against a wall, which is a small thing that makes a big difference in a cramped garage.
If storage is not an issue, the FIMCO 5303198 or CHAPIN 97664 offer more power for similar money. The Brinly trades raw performance for a clever storage solution.
Real user feedback from lawn care forums
On thelawnforum.com, Brinly sprayers get consistent praise for the storage design and Brinly’s customer service. Multiple owners report that Brinly replaced defective parts quickly without hassle, which is rare in this category. The 2-year warranty backs up that service reputation.
The common thread in forum discussions is that the Brinly is a homeowner-grade sprayer, not a commercial unit. For weekly use on a 1 to 2-acre property, it works well. For daily commercial use on 5+ acres, look at the NorthStar or CHAPIN 40-gallon instead.
8. Brinly ST-251BH-A 25-Gallon Sprayer – Heavy-Duty Mid-Size Pick
Brinly Self-Storing Tow Behind Lawn and Garden Sprayer with Collapsible Boom, 25-Gallon
25-gallon tank
12V pump
Ultra Lo-Drift tips
Pros
- Heavy-duty steel frame with powder-coated finish
- Ultra Lo-Drift spray tips
- 12-foot hose with thumb control spray gun
- Universal hitch for all lawn tractors
Cons
- Plastic fittings can be cheap
- Some frame buckling reported under heavy use
- Assembly required
The Brinly ST-251BH-A 25-Gallon Self-Storing Tow-Behind Sprayer is the bigger sibling of the ST-152BH-A, with the same vertical storage trick but more capacity. At 25 gallons, it covers about three-quarters of an acre per fill, which puts it in the same league as the Grass Guardian but with Brinly’s better build quality and customer service.
The heavy-duty steel frame with powder-coated finish is the main upgrade over the 15-gallon model. This frame does not flex under load, and the powder coat is holding up well after three months of testing. The non-corrosive tank, tubes, and valves handle most residential herbicides and fertilizers without degradation.
The Ultra Lo-Drift spray tips are a nice touch. These nozzles produce larger droplets that are less likely to drift in wind, which matters when you are spraying near vegetable gardens or sensitive plants. I tested them on a 10 mph wind day, and the drift was noticeably less than with the standard FloodJet nozzles on the FIMCO.
The 12-foot hose with ergonomic thumb control spray gun is comfortable to use, and the tractor-mounted on/off switch lets you control the pump from the driver seat. The universal hitch attaches to every lawn tractor and most zero-turn mowers and ATVs, so compatibility is not an issue.
The downsides: some of the plastic fittings are still cheap, and a few owners report frame buckling under heavy use. With only 48 reviews, the long-term durability data is limited. At $469, it is priced higher than the Grass Guardian 25-gallon, but you are paying for the steel frame and the self-storing design.
Comparing the two Brinly models side by side
The ST-152BH-A (15-gallon) and ST-251BH-A (25-gallon) share the same self-storing design and quality reputation. The main differences are tank capacity, frame construction, and price. The 25-gallon has a heavier steel frame, the 15-gallon uses a lighter frame that is fine for residential use.
If you have a 1-acre property and tight storage, the 15-gallon is the right call. If you have 2 to 3 acres and want the heavier frame for rough terrain, the 25-gallon is worth the extra $120.
Made in USA and warranty coverage
Both Brinly sprayers are made in the USA with a 2-year warranty. Brinly’s customer service is consistently rated higher than most competitors, and replacement parts are available directly from the manufacturer. For homeowners who value American manufacturing and responsive support, Brinly is a smart pick over the imported alternatives.
The 2-year warranty covers defects in materials and workmanship, which includes the pump, frame, and tank. It does not cover wear items like nozzles, hoses, or seals, but those are cheap and easy to replace.
How to Choose the Right Tow-Behind Sprayer?
Choosing the best tow-behind sprayer for your property comes down to four questions: how many acres are you treating, what are you spraying, what vehicle will tow it, and where will you store it. Get those answers right and the rest is easy.
Tank size and property coverage
The most common sizing mistake is buying a tank that is too small. A 13-gallon tank covers about a third of an acre per fill, which means constant refilling on anything over an acre. A 25-gallon tank covers about three-quarters of an acre per fill, and a 40-gallon covers about 1.5 acres. For most homeowners with 1 to 3-acre properties, 25 gallons is the sweet spot.
Here is a quick coverage estimate. At a typical 1 gallon per 1000 square feet application rate, a 25-gallon tank will cover about 25,000 square feet, or roughly 0.6 acres. Plan on needing 1.5 fills per acre treated. For 2,4-D and most liquid herbicides, the application rate is similar.
Boom versus boomless nozzles explained
A boom sprayer uses a horizontal bar with two or more nozzles that create a wide, even spray pattern. A boomless sprayer uses a single nozzle that throws spray in a wider arc, covering a similar swath without the boom. Each has trade-offs.
Boom sprayers produce a more uniform pattern and are easier to calibrate, but the boom is vulnerable to damage on rough ground or near obstacles. Boomless sprayers are more durable and easier to maneuver, but the pattern is less even at the edges. For most residential use, a boom sprayer with breakaway hinges is the better choice.
Pump power and GPM ratings
GPM stands for gallons per minute, and it tells you how fast the pump can move liquid through the system. A 1.0 GPM pump is fine for spot spraying and small boom setups. A 2.0 to 2.5 GPM pump is better for wide booms and thick liquid mixes. For most residential tow behind sprayers, 1.0 to 1.5 GPM is enough.
PSI is the pressure the pump generates, and it affects droplet size and spray distance. Higher PSI means smaller droplets, which cover better but drift more in wind. Most tow behind sprayers run at 40 to 70 PSI, which is a good balance for herbicide application.
Compatibility with your towing vehicle
Most tow behind sprayers use a standard pin hitch that fits lawn tractors, zero-turn mowers, ATVs, and UTVs. Some larger units, like the CHAPIN 98444 40-Gallon, use a 3-point hitch that requires a compact tractor. Make sure the sprayer you buy matches your towing vehicle before you pull the trigger.
For the 12V pump, you need a battery connection. Most sprayers come with a wiring harness that clamps directly to a 12V battery, and the harness is long enough to reach the battery on most lawn tractors and ATVs. Some zero-turn mowers have accessory ports that can power a sprayer without direct battery connection.
Maintenance and winterization tips
To make any tow behind sprayer last, flush the system with clean water after every use, especially when using herbicides. Residual chemicals will corrode seals and clog nozzles if left in the pump. After the final fall spray, drain the tank completely, run the pump until it is dry, and store the sprayer in a shed or garage.
For winter storage in freezing climates, add RV antifreeze to the pump and run it through the system. This prevents the pump diaphragm and valves from cracking when the water inside expands. In spring, flush the antifreeze out with clean water before adding herbicides.
Frequently Asked Questions
What is the best tow-behind sprayer on the market?
The NorthStar 31-Gallon Tow-Behind Sprayer is the best overall option for most homeowners. It has a commercial-grade 2.2 GPM pump at 70 PSI, a 120-inch spring-loaded breakaway boom, and nearly 2,000 reviews averaging 4.2 stars. For smaller properties, the Ironton 13-Gallon offers solid performance under $250.
How many acres will 25 gallons of sprayer cover?
A 25-gallon tank covers approximately 0.6 acres per fill at a standard 1 gallon per 1000 square feet application rate. For 1 to 2-acre properties, plan on refilling once mid-job. For 2 to 3-acre properties, a 40-gallon tank like the CHAPIN 98444 lets you finish the job in one fill.
Which is better, a boom or a boomless sprayer?
A boom sprayer produces a more uniform spray pattern and is easier to calibrate, but the boom is vulnerable to damage on rough ground. A boomless sprayer is more durable and easier to maneuver near obstacles, but the pattern is less even at the edges. For most residential use, a boom sprayer with breakaway hinges offers the best balance.
What size tow-behind sprayer do I need for my lawn?
For a half-acre to 1-acre lawn, a 13 to 15-gallon tank is enough. For 1 to 3 acres, a 25-gallon tank is the sweet spot. For 3+ acres, look at 40-gallon units like the CHAPIN 98444. Buying a larger tank than you need adds weight and takes up storage space, but it saves time on refills.
How do I maintain a tow-behind sprayer?
Flush the system with clean water after every use, especially after spraying herbicides. Drain the tank and run the pump dry before storage. In freezing climates, pump RV antifreeze through the system to protect the diaphragm and valves. Replace hose clamps annually and check nozzle patterns for wear at the start of each season.
Final Verdict
After testing eight of the best tow-behind sprayers on the market, the NorthStar 31-Gallon Tow-Behind Sprayer is my top pick for most homeowners. The commercial-grade pump, spring-loaded breakaway boom, and recirculation feature make it the most reliable unit I tested, and the 4.2-star average across 1,961 reviews confirms what I saw in the field. For a budget option, the Ironton 13-Gallon is hard to beat, especially if you are willing to swap a few cheap parts. For 3+ acre properties, the CHAPIN 98444 40-Gallon is the right size.
Whatever tow behind sprayer you choose in 2026, match the tank size to your property, pick a boom style that fits your terrain, and budget for replacement hose clamps in the first month. Those three decisions will save you the most frustration over the life of the sprayer.
