8 Best Tow Behind Sprayers (September 2026) Tested & Ranked

After three months of testing eight different tow behind sprayers across my own 4-acre property and a neighbor’s 12-acre pasture, I can tell you which models actually deliver on their promises. We sprayed everything from pre-emergent herbicide on lawn to liquid fertilizer on pastures, hauling each sprayer behind both a riding mower and an ATV. Out of the eight units we tested, three clearly stood out for different reasons, and the differences between them might surprise you.

If you maintain more than one acre of lawn, pasture, or food plot, a quality tow behind sprayer will save you hours of back-breaking work with a backpack or handheld pump sprayer. The best tow behind sprayers combine adequate tank capacity with reliable pumps, and they attach easily to whatever riding equipment you already own. We focused on pull behind sprayers with boom systems because they offer the most uniform coverage for large areas, but we also included boomless options for buyers who need to spray around trees and obstacles.

Our testing covered real-world durability across multiple chemicals, ease of assembly out of the box, pump performance under load, and how each sprayer handled uneven terrain. This guide gives you everything you need to pick the right tow behind sprayer for your property, your tow vehicle, and your budget. I’ve included a coverage calculator section to help you match tank size to acreage, plus a boom vs boomless comparison that addresses the most common buyer confusion.

Top 3 Picks for Best Tow Behind Sprayers

Best Tow Behind Sprayers in 2026

1. Master Mfg 36-Gallon Premium Tow-Behind Sprayer – Editor’s Choice for Heavy-Duty Use

The Master Mfg 36-Gallon Premium pull behind sprayer is the most impressive unit I tested in 2026. Right out of the box, the build quality stands apart. The 16-inch heavy-duty tires rolled over rough pasture ground that made other sprayers bounce and skip. The Everflo 3.0 GPM diaphragm pump is the highest-flow pump in this roundup, and it shows during operation. I sprayed a full 36-gallon tank of liquid nitrogen fertilizer without any pressure drop, even when the tank ran low.

The 10-foot broadcast swath from six quick-attach no-drip nozzles gave the most uniform coverage of any tow behind sprayer I tested. On my lawn, the spray pattern overlapped cleanly with each pass, eliminating the striping you see with narrower booms. The 36-gallon capacity covered my entire 2-acre lawn test area in one fill, which saved significant time over 15 and 25-gallon models.

The folding boom design is a thoughtful touch for storage. I could collapse the entire boom horizontally against the trailer frame, cutting the footprint by roughly half. This matters if you’re storing it in a tight garage or shed. Master Manufacturing has earned a reputation in the r/lawncare community for reliability, and my testing confirms that reputation holds up.

The biggest downside is shipping time. Mine took 19 days to arrive, which is longer than I’d like for a planned project. Once it arrived, assembly took about 45 minutes with basic hand tools. The instructions are clear, and all hardware was included in my unit. For buyers willing to plan ahead, this is the best tow behind sprayer for serious acreage work.

Who should buy this sprayer

If you maintain 3+ acres of lawn or pasture and want the most coverage per pass, the Master Mfg 36-Gallon is hard to beat. The high GPM pump handles thicker liquids like wettable powders better than lower-flow alternatives. I recommend it for property owners who prioritize build quality and long-term reliability over quick shipping.

Who should skip this sprayer

If you only need to spray a single acre or less, the 36-gallon tank is overkill and you’ll be hauling unnecessary weight. The 2-4 week shipping window also makes it a poor choice if you need a sprayer urgently for an upcoming treatment window. For those cases, the Amazon Prime-eligible Chapin 25-Gallon is a better fit.

2. NorthStar 31-Gallon Tow-Behind Boom/Spot Sprayer – Best Overall Value

The NorthStar 31-Gallon is the tow behind sprayer I’d recommend to most buyers based on my testing. With over 1900 reviews averaging 4.2 stars, it has the deepest track record of any model in this roundup. The NSQ Series 2.2 GPM pump is rated for 100% continuous duty, which means you can run it at full pressure for as long as your battery holds out. During my testing, I sprayed for over two hours continuously without any performance drop.

The 120-inch spring-loaded breakaway boom is the standout feature. When I accidentally backed into a fence post, the boom folded back instead of snapping, then popped right back into position. That single feature probably saved me a couple hundred dollars in replacement parts. The 80-inch effective spray width gave uniform coverage on my lawn test area.

The recirculation feature is something I didn’t appreciate until I used it. It keeps liquid fertilizer or wettable powder mixed by continuously cycling solution back through the tank. Without this, I noticed settling in other sprayers within 20 minutes, leading to uneven application. With the NorthStar, the mixture stayed consistent for the full 31 gallons.

The handheld spray wand is genuinely cheap plastic. I swapped mine for an aftermarket brass wand within a week. This is the most common complaint in customer reviews, and NorthStar has clearly cut costs here. The other assembly issue is loose hose clamps – I had to retighten four clamps during initial setup. Plan for about 30 minutes of tinkering before first use.

Who should buy this sprayer

Buyers who want proven reliability backed by thousands of real-world reviews should put the NorthStar 31-Gallon at the top of their list. The combination of commercial-grade pump, recirculation feature, and breakaway boom justify the price premium over budget models. It’s particularly well-suited for properties between 2 and 5 acres.

Who should skip this sprayer

If you need a sprayer today rather than next week, NorthStar models typically aren’t Prime eligible. The 31-gallon capacity also adds weight that smaller riding mowers may struggle to pull on hills. For smaller properties or faster shipping, consider the NorthStar 21-Gallon or Chapin 25-Gallon instead.

3. NorthStar 21-Gallon Tow-Behind Boom/Spot Sprayer – Best Mid-Size Performer

The NorthStar 21-Gallon is essentially the smaller sibling of the 31-gallon model, sharing the same NSQ 2.2 GPM commercial pump and 120-inch breakaway boom. With nearly 2000 reviews averaging 4.2 stars, it has nearly identical real-world validation to its bigger brother. I tested it on a 1.5-acre lawn section and it performed flawlessly, with the same recirculation and pressure consistency as the larger model.

The key advantage here is weight. At 53 pounds empty, the 21-gallon model is light enough that smaller lawn tractors and most ATVs handle it easily on hills and uneven ground. I towed it behind a 42-inch deck riding mower without any noticeable strain. The removable axle and wheels make storage even more compact than the 31-gallon.

The patented DXS-3 Viton valves in the pump resist breakdown from harsh chemicals like 2,4-D and other broadleaf herbicides. This is a meaningful upgrade over generic pump valves that can swell and fail after a season of aggressive herbicide use. For buyers who spray a variety of chemicals, this detail matters for long-term durability.

The trade-off is more frequent refills. On a 2-acre property, you’ll refill at least once. For most homeowners with 1-2 acres, this isn’t a major issue. The 21-gallon is also a popular choice among users transitioning from backpack sprayers – it offers the same pump quality as larger units in a more manageable package.

Who should buy this sprayer

Buyers with properties between 1 and 2 acres get the best balance of capacity and towability with the 21-Gallon. It’s also the right pick if your tow vehicle is a smaller riding mower or ATV. The Viton valve upgrade makes it a smart long-term investment if you spray multiple chemical types.

Who should skip this sprayer

If your property is over 2 acres, you’ll spend more time refilling than spraying. Step up to the 31-Gallon for those situations. Buyers who want the highest GPM pump available should look at the Master Mfg 36-Gallon with its 3.0 GPM Everflo pump.

4. FIMCO 15-Gallon Trailer Sprayer – Best Compact Option

The FIMCO 15-Gallon trailer sprayer fills a specific niche: buyers with small properties who don’t want to wrestle with a 25+ gallon tank. I tested this on a 1-acre lawn and it completed the job with about a quarter tank to spare. The compact footprint also makes it the easiest to store – it fit in my garden shed without any boom disassembly.

The 1.2 GPM High Flo pump is adequate for the smaller tank but runs at noticeably lower pressure than the NorthStar units. Boom coverage is 7 feet total from two nozzles, which is fine for residential lawns but means more passes on wider properties. The lever-grip spray wand with adjustable polymer nozzle reaches 20 feet horizontally, which is genuinely impressive for spot spraying trees or fence lines.

FIMCO is the manufacturer-direct competitor in this space. The build quality feels commercial-grade despite the lower price point. The TeeJet FloodJet nozzles produce a flat fan pattern that resists drift better than cone-pattern nozzles in light wind. The bonus DU-Most hand scrub cleaner is a small but appreciated touch for cleanup after chemical handling.

The main concern in customer reviews is occasional pump failures out of the box. I didn’t experience this in my unit, but I’d recommend testing the pump with plain water before adding any chemicals. FIMCO’s customer service has been responsive to warranty claims based on forum reports, which provides some peace of mind.

Who should buy this sprayer

Buyers with properties under 2 acres who value compact storage will appreciate the FIMCO 15-Gallon. It’s also a good upgrade from a backpack sprayer for homeowners who want boom coverage without the weight of a 25-gallon tank. The included hand scrub cleaner is a nice bonus for safety-minded users.

Who should skip this sprayer

If you maintain more than 2 acres, the small tank and lower GPM pump will slow you down considerably. For larger properties, the NorthStar 21-Gallon or Master Mfg 36-Gallon will save significant time. Buyers who need the strongest pump available should look elsewhere.

5. Chapin 40-Gallon 3-Point Hitch Sprayer – Best for Large Acreage

The Chapin 40-Gallon 3-Point Hitch Sprayer is the largest capacity model in our test, and it’s specifically designed for serious acreage work. The 40-gallon translucent poly tank let me see exactly how much solution remained without climbing off the tractor – a small detail that turned out to be surprisingly useful during long spraying sessions.

The 2.5 GPM self-priming diaphragm pump is the second-highest flow rate we tested, behind only the Master Mfg 3.0 GPM unit. This matters when spraying wettable powders or thicker liquid fertilizers that can clog smaller pumps. The triple filtration system – filter basket, in-tank filter, and inline filter at the shutoff – kept operation smooth even with less-than-perfectly-mixed solutions.

Being made in the USA with USA-based customer service is a real differentiator. When I called Chapin’s technical support line with a question about winterizing, I reached a knowledgeable person in under five minutes. The 1-year limited warranty provides backup if anything fails. Several forum users specifically mentioned Chapin’s support as a reason they chose this brand over imports.

The 3-point hitch design is the main limitation. If your tow vehicle doesn’t have a 3-point hitch (most riding mowers and ATVs don’t), you’ll need an adapter. This makes the Chapin 40-Gallon best suited for compact tractors and larger garden tractors. The 60 PSI maximum pressure is lower than NorthStar’s 70 PSI, though I didn’t notice a meaningful difference in spray pattern during testing.

Who should buy this sprayer

Property owners with compact tractors and 4+ acres of spraying needs will benefit most from the Chapin 40-Gallon. The large tank reduces refill stops, and the triple filtration handles rougher chemical mixes. USA manufacturing and support add long-term value if you keep equipment for many seasons.

Who should skip this sprayer

If you’re towing with a standard riding mower, ATV, or UTV without a 3-point hitch, this sprayer won’t work without an adapter. Smaller properties under 3 acres don’t need the 40-gallon capacity. Consider the Chapin 25-Gallon ATV model or NorthStar 21-Gallon for those situations.

6. Chapin 25-Gallon Tow-Behind ATV Sprayer – Best ATV/UTV Mount

The Chapin 25-Gallon ATV Sprayer is purpose-built for off-road use. The EZ Mount system let me attach it to my ATV rack in about 5 minutes without tools, and the straps held secure even over rough terrain. For buyers who already own an ATV and need a tow behind sprayer, this is the most convenient option in the roundup.

The 2.5 GPM Chapin 12V diaphragm pump matches the larger 40-Gallon model, which is impressive at this price point. Spray performance was consistent throughout my testing, and the 7-foot boom pattern worked well for pasture edges and food plot borders. The triple filtration system matched the 40-Gallon, which is uncommon at this capacity level.

The translucent poly tank made it easy to monitor fluid level while riding. This turned out to be more useful than I expected – I could tell exactly when to head back to the refill station without stopping to check. The included 19-inch poly wand and 180-inch reinforced hose provide solid spot spray capability for fence lines and individual weeds.

The 3.9-star average rating reflects some durability concerns. About 17% of reviewers gave 1-star ratings, with most complaints about pump or tank failures within the first year. I didn’t experience these issues during my 3-month test, but it’s a higher failure rate than the NorthStar models. Buyers who prioritize proven longevity over EZ Mount convenience may prefer the NorthStar 21-Gallon.

Who should buy this sprayer

ATV and UTV owners will appreciate the tool-free EZ Mount system on the Chapin 25-Gallon. It’s also a strong choice for buyers who want a 2.5 GPM pump without paying for the 40-Gallon capacity. The Prime eligibility makes it a good option for buyers who want fast shipping.

Who should skip this sprayer

Buyers concerned about long-term durability should look at the NorthStar 21-Gallon or 31-Gallon, which have higher reliability track records. If your tow vehicle is a compact tractor with a 3-point hitch, the Chapin 40-Gallon offers more capacity for similar money.

7. Brinly Self-Storing 25-Gallon Tow-Behind Sprayer – Best for Tight Storage

The Brinly Self-Storing 25-Gallon sprayer solves a problem that frustrates many tow behind sprayer owners: storage space. The collapsible swing-away booms fold back against the trailer frame when not in use, cutting the storage footprint by about a third. In my garage, this was the difference between fitting the sprayer on the wall versus taking up floor space.

The Ultra Lo-Drift spray tips are a unique feature worth highlighting. Standard cone-pattern nozzles produce fine droplets that drift in even light wind, wasting chemical and potentially damaging non-target plants. The Lo-Drift tips produce larger droplets that resist drift while still providing good coverage. I tested this on a breezy day and saw noticeably less off-target spray compared to other sprayers in the test.

Brinly has been making lawn equipment in the USA since 1839. The steel frame with powder-coated finish feels more substantial than the plastic frames on some competitors. The single-pin universal hitch attached to every tow vehicle I tried, from a riding mower to a zero-turn to an ATV. The 2-year warranty is the longest in our roundup, providing extra peace of mind.

The main drawback is limited stock availability – I had to wait for restocking before I could even order mine. With only 48 reviews averaging 4.0 stars, the track record is shorter than NorthStar or Chapin models. For buyers who need a sprayer immediately, the limited inventory is a real constraint.

Who should buy this sprayer

Buyers with limited storage space will appreciate the collapsible boom design on the Brinly 25-Gallon. Properties in windy areas benefit significantly from the Lo-Drift spray tips. The 2-year warranty and long manufacturer history provide confidence for buyers planning to keep the sprayer many seasons.

Who should skip this sprayer

If you need a sprayer urgently, the limited stock makes Brinly a risky choice. For larger properties, the 25-Gallon Master Mfg or 31-Gallon NorthStar offer better coverage per fill. Buyers who prioritize the deepest review base should consider NorthStar models.

8. Ironton 13-Gallon Tow-Behind Sprayer – Best Budget Pick

The Ironton 13-Gallon tow behind sprayer is the most affordable option in our roundup, and it punches above its weight class. At 29.4 pounds empty, it’s the lightest sprayer we tested. This made it ideal for towing behind a smaller riding mower without worrying about traction on hills. The 522 reviews averaging 4.2 stars show consistent real-world satisfaction.

The Roundup approval is a meaningful certification for buyers who spray agricultural herbicides. Not all tank materials are compatible with concentrated glyphosate products – some degrade over time. The Ironton’s UV-resistant tank handles Roundup and similar products without issues, which the manufacturer specifically validated.

I tested this on a small 0.75-acre lawn section and it performed the task completely. The 1 GPM pump is the slowest in our roundup, but for a 13-gallon tank, the flow rate is appropriate. The molded gallon markers let me track fluid levels without translucent tank walls. The 7.5-inch tank opening made filling easy from a 5-gallon bucket without splashing.

The obvious trade-off is small capacity. On anything over 1 acre, you’ll spend significant time refilling. The basic feature set lacks some conveniences of premium models – no recirculation, no breakaway boom, no pressure gauge. For buyers who just need a simple, reliable sprayer for occasional use, these aren’t dealbreakers.

Who should buy this sprayer

First-time tow behind sprayer buyers will appreciate the Ironton’s low price and simple operation. Properties under 1 acre get full value from the 13-gallon capacity. Buyers on a tight budget who want Roundup compatibility will find this is the best tow behind sprayer for their needs.

Who should skip this sprayer

If your property is over 1 acre, the 13-gallon tank will leave you refilling constantly. Step up to the 15-gallon FIMCO or 21-gallon NorthStar for more capacity. For the best overall value, the NorthStar 21-Gallon offers superior pump quality for only slightly more money.

How to Choose the Best Tow Behind Sprayer for Your Property

Choosing the right tow behind sprayer comes down to matching capacity and features to your specific needs. The biggest mistake I see buyers make is over-buying tank capacity for a small property, or under-buying for acreage work. Let me walk through the key decision factors I considered during testing.

Tank Capacity by Property Size

The most common question buyers ask is how many acres a tank will actually spray. The answer depends on your application rate, which varies by chemical. Most lawn herbicides apply at 1-2 gallons per 1000 square feet. Pasture fertilizers often apply at 10-20 gallons per acre. Here is a quick reference based on a typical 1 gallon per 1000 sq ft application rate:

• 13 gallons: Covers roughly 0.12 acres (about 5,200 sq ft) per tank
• 15 gallons: Covers roughly 0.14 acres (about 6,000 sq ft) per tank
• 21 gallons: Covers roughly 0.19 acres (about 8,400 sq ft) per tank
• 25 gallons: Covers roughly 0.23 acres (about 10,000 sq ft) per tank
• 31 gallons: Covers roughly 0.28 acres (about 12,400 sq ft) per tank
• 36 gallons: Covers roughly 0.33 acres (about 14,400 sq ft) per tank
• 40 gallons: Covers roughly 0.37 acres (about 16,000 sq ft) per tank

For larger properties, multiply accordingly. A 25-gallon tank covers about 1 acre across 4 refills at standard herbicide rates. A 36-gallon tank covers about 1 acre across 3 refills. If you maintain 3+ acres, the larger 36 or 40-gallon tanks save significant refill time.

Boom vs Boomless Sprayer Comparison

This is the most common buyer decision point, and it depends on your property layout. Boom sprayers use a horizontal bar with multiple nozzles that spray downward in a fan pattern. Boomless sprayers use a single nozzle that sprays outward in a wider arc. Here is how they compare:

• Boom sprayer pros: Most uniform coverage, lowest drift in wind, best for open lawns and pastures, easier to calibrate application rate
• Boom sprayer cons: Boom can catch on obstacles, requires disassembly or folding for storage, can be damaged backing up
• Boomless sprayer pros: No boom to catch on obstacles, simpler design with fewer parts, easier to maneuver around trees and landscaping
• Boomless sprayer cons: Less uniform coverage, more drift in wind, harder to control application rate, lower precision

For most buyers with open lawn or pasture, a boom sprayer is the better choice because uniform coverage matters more than obstacle avoidance. If your property has many trees, fence lines, or other obstacles, consider a boomless model or one with breakaway booms like the NorthStar units.

Understanding Pump Specs (GPM and PSI)

The pump is the heart of any tow behind sprayer, and the two specs that matter most are GPM (gallons per minute) and PSI (pounds per square inch). GPM determines how much liquid the pump can move – higher GPM means faster spray coverage and better handling of thick liquids. PSI determines spray pressure – higher PSI means finer droplets and longer throw distance.

For most homeowners, a 1.5-2.5 GPM pump is sufficient. The Master Mfg 3.0 GPM and Chapin 2.5 GPM pumps handle wettable powders and thicker fertilizers best. The NorthStar 2.2 GPM pump hits a sweet spot for typical lawn and garden use. PSI between 40-70 covers virtually all homeowner needs.

Tow Vehicle Compatibility

Before buying, verify your tow vehicle can handle the loaded weight. Water weighs 8.3 pounds per gallon, so a 25-gallon tank weighs over 200 pounds when full. Add the empty sprayer weight (typically 30-80 pounds) and you’re looking at 230-280+ pounds of total tow weight. Most riding mowers handle this fine, but small ATVs may struggle on hills.

Three hitch types appear in our roundup: standard pin hitch (fits most riding mowers, ATVs, UTVs), 3-point hitch (fits compact tractors only), and EZ Mount straps (fits ATV racks). The NorthStar and Brinly units use standard pin hitches for maximum compatibility. The Chapin 40-Gallon requires a 3-point hitch, limiting it to compact tractors.

Chemical Compatibility and Cross-Contamination

Cleaning between chemical types is one of the most tedious aspects of using a tow behind sprayer, according to forum users. Residue from herbicides like 2,4-D can damage sensitive plants if you switch to fertilizer without thorough cleaning. Plan for 15-30 minutes of flushing with clean water between chemical changes.

The Viton valves in NorthStar pumps and the chemical-resistant seals in Chapin models handle a wider range of chemicals than basic pumps. If you plan to spray multiple chemical types, invest in a sprayer with these upgraded seals. Triple filtration systems (Chapin models) also reduce clogs when switching between liquid and powder products.

After testing all eight tow behind sprayers across multiple chemicals, terrain types, and tow vehicles, my top pick for most buyers is the Master Mfg 36-Gallon Premium Trailer Sprayer. The 10-foot broadcast swath and 3.0 GPM pump delivered the most uniform coverage with the fewest refills, and the build quality feels built for a decade of regular use. For buyers wanting proven reliability backed by thousands of reviews, the NorthStar 31-Gallon remains the best value choice.

If your property is under 1 acre and you want to spend less, the Ironton 13-Gallon is the best budget pick – Roundup approved, lightweight, and backed by 522 reviews averaging 4.2 stars. For ATV owners, the Chapin 25-Gallon with EZ Mount is the most convenient option. Whatever sprayer you choose from this list, you’re getting one of the best tow behind sprayers available in 2026.
