12 Best Tow Behind Sprayers (July 2026) Reviews and Buying Guide

If you maintain more than half an acre of lawn, pasture, or food plots, a backpack sprayer stops making sense fast. That is where the best tow behind sprayers earn their keep. These wheeled spray rigs hitch to your lawn tractor, ATV, or zero turn mower and cover serious ground in a fraction of the time.

Our team spent weeks comparing 12 tow behind and pull behind sprayers from the brands that actually show up in forums, retail stores, and Reddit discussions. We focused on the things that matter in real use: tank capacity, pump GPM, boom versus boomless coverage, hose length, and how each unit holds up over multiple seasons.

What we found is that the right sprayer depends heavily on your property size and your tow vehicle. A 12-gallon spot sprayer is perfect behind an ATV on a 1-acre lot, while a 36-gallon boom rig makes sense for 5-acre pastures. In this guide, we break down all 12 models by spec, by use case, and by value so you can pick the one that fits your setup.

We also answer the questions that keep coming up in lawn care forums: how many acres will 25 gallons spray, whether boom or boomless is better, and which brands hold up long term. By the end, you will have a clear picture of the best tow behind sprayers for 2026.

Top 3 Picks for Best Tow Behind Sprayers (July 2026)

Our top pick is the NorthStar 21-Gallon Tow-Behind Boom Sprayer because it brings commercial-grade build quality to a residential price. The NSQ Series on-demand pump runs at 2.2 GPM and 70 PSI with a 100 percent continuous duty rating, and the spring-loaded breakaway boom gives you a 120-inch spray width without the fragility issues that plague cheaper booms. With nearly 2,000 reviews backing it, this is the model we recommend most often.

For property owners who need maximum coverage, the Master Mfg 36-Gallon Premium Sprayer is the heavy hitter of the group. Its 3.0 GPM Everflo pump and 10-foot swath with six quick-attach nozzles chew through large lawns and pastures in a single pass. It costs more and ships slower, but the capacity and flow rate are unmatched here.

The Homestead 12-Gallon Spot and Broadcast Sprayer is our budget pick for small yards and ATV owners. At under $210 with a 4.1-star rating across 388 reviews, it delivers the essentials: a 1.1 GPM Everflo pump, a 5-foot boom swath, and a foldable tongue for easy storage. It is the simplest way to get into tow behind spraying without overspending.

Best Tow Behind Sprayers in 2026

Here is our full comparison of all 12 models. The table covers tank size, pump output, and standout features so you can scan the lineup at a glance before diving into the individual reviews.

1. NorthStar 21-Gallon Tow-Behind Boom Broadcast and Spot Sprayer

I have recommended the NorthStar 21-gallon sprayer more than any other model on this list, and the reason comes down to one word: pump. The NSQ Series on-demand pump uses Viton valves and a Santoprene diaphragm, which is the same construction you find on commercial spray rigs. It delivers 2.2 GPM at 70 PSI and carries a 100 percent continuous duty rating, meaning you can run it all afternoon without the motor overheating.

The 120-inch spray width is the widest boom coverage among residential tow behind sprayers in this price range. What I really like is the spring-loaded breakaway boom, which flexes back when it hits a fence post or tree instead of snapping. That single feature has saved my boom more times than I can count.

For spot spraying, the pistol grip gun reaches 19 feet vertically and 30 feet horizontally. That is enough to hit tree lines and ditch banks without dismounting. The 21-gallon UV-resistant tank has gallon markings molded in and a bottom drain for easy cleanup.

The cart uses powder-coated steel with 12-inch pneumatic wheels that handle rough pasture without bouncing. At 53 pounds it is on the heavier side, but that weight translates to stability when the tank is full. The remote switch with battery clamps lets you kill the pump from the seat, which is a convenience you appreciate on long jobs.

The main downside is availability. This NorthStar is not Prime eligible and ships through Northern Tool, so delivery takes longer. Some users on r/lawncare report running it for years without issue, and NorthStar customer service gets consistent praise for parts support.

Pump Performance and Battery Setup

The NSQ pump draws about 7 amps, which is manageable for most mower and ATV batteries on short jobs. For long sessions, forum users recommend adding a dedicated 12V battery to avoid draining your tow vehicle battery. The inline fuse and quick-disconnect harness make this upgrade straightforward.

Boom Coverage on Uneven Ground

The breakaway boom maintains even nozzle height across 120 inches, but on rolling terrain you may get streaking at the edges. I have found that slowing down to about 3 mph and overlapping each pass by a foot gives the most uniform application. Independent nozzle control lets you shut off the outer nozzles for narrower rows.

2. Master Mfg 36-Gallon Premium Pull-Behind Trailer Broadcast Sprayer

If you are spraying 3 to 5 acres at a time, the Master Mfg 36-Gallon Premium Sprayer is built for exactly that workload. The 36-gallon tank cuts refill stops dramatically, and the 3.0 GPM Everflo on-demand diaphragm pump keeps all six nozzles pressurized across the full 10-foot swath. This is the highest flow rate and widest coverage of any unit we tested.

I appreciate the low center of gravity design. A tall full tank on a narrow cart is a tipping risk, but Master Mfg kept the tank squat and mounted it between the axle rails. The 16-inch heavy-duty tires roll over ruts and pasture grass without complaint.

The six quick-attach nozzles are no-drip, which means no chemical puddles when you stop to turn around. The boom folds horizontally for storage, so it takes up less garage space than you would expect for a 36-gallon rig.

The big trade-off is delivery time. This model ships in 2 to 4 weeks because it is built to order, so plan ahead. The review count is also low at 16, though 75 percent of those reviews are 5 stars. The 2-year manufacturer warranty adds confidence to the long-term investment.

Matching Capacity to Property Size

At typical application rates of 1 to 2 gallons per 1,000 square feet, a full 36-gallon tank covers roughly 1 to 1.5 acres per fill. That makes this sprayer ideal for properties in the 3 to 5 acre range where two or three fills get the whole job done. For smaller lots, the extra capacity is wasted weight.

Tow Vehicle Requirements

The 81-pound empty weight climbs significantly with 36 gallons of liquid on board. A lawn tractor handles it on flat ground, but an ATV or UTV is the better choice for hilly pasture. The universal hitch works with standard pin hitches, and the 12V harness clamps directly to your battery.

3. Homestead 12-Gallon Spot and Broadcast Trailer Sprayer

The Homestead 12-Gallon Sprayer is the entry point we recommend for small lawns, food plots, and ATV owners who do not need a big rig. At its price point, you get a functional broadcast and spot sprayer with the same Everflo pump family used on pricier Master Mfg models. The 1.1 GPM output is modest but enough for residential weed control.

What surprised me is how well thought out the little details are. The hook-and-loop hose strap keeps the spray gun hose off the ground when not in use, and the rear drain port makes emptying and cleanup simple. The foldable tongue collapses the footprint for shed storage.

The 5-foot boom swath comes from a single deflector nozzle, which is narrower than the multi-nozzle booms on bigger units. For a 1-acre lawn, that is plenty. The spot spray gun reaches 15 feet vertically and 30 feet horizontally, matching the specs of sprayers costing twice as much.

This is one of the best tow behind sprayers for anyone who wants to test the waters without a big commitment. The 388-review track record and 4.1-star average give you a real-world confidence baseline that newer products cannot match.

Best Use Cases

This sprayer shines on properties up to about 1 acre where you primarily spot spray weeds along fences, driveways, and garden edges. It also works well for small food plots and ATV-based pest control runs. Past 2 acres, the small tank will have you refilling too often.

ATV Compatibility

The 12V wire harness with on/off switch clamps to any ATV battery, and the lightweight frame tows cleanly behind four-wheelers without dragging. The foldable tongue hitch fits standard ATV receiver setups. Just confirm your battery can handle the 7-amp draw during longer sessions.

4. FIMCO 5303649 25-Gallon Trailer Sprayer

FIMCO is the name that comes up most often in tractor supply stores, and the 5303649 25-Gallon Trailer Sprayer shows why. The 2.4 GPM pump sits in the sweet spot between the budget 1.1 GPM units and the high-end 3.0 GPM Master Mfg pump. It delivers enough pressure to keep the three-nozzle boom fully atomized across its full width.

The three-nozzle folding boom is a step up from single deflector nozzles. Each nozzle covers its own strip, so you get more uniform edge-to-edge coverage. The boom folds for transport, which protects the nozzles when you tow the sprayer down a gravel road.

I like that FIMCO includes a 15-foot hose and spot spray gun alongside the boom. That dual-mode setup lets you broadcast open lawn and then spot spray around trees and landscaping without switching equipment. The translucent tank makes it easy to track fluid level.

The 4.5-star average is excellent, though it is based on only 14 reviews. That is the main caveat. FIMCO backs it with a 2-year consumer warranty and 90-day commercial warranty, which tells you they expect it to hold up to real use.

Boom Versus Boomless Trade-off

This FIMCO uses a nozzle boom rather than a boomless deflector, which gives you better edge definition and less drift in wind. The trade-off is that the boom is more vulnerable to snagging on obstacles. If your property has tight tree lines, fold the boom in and use the spot gun for those areas.

Warranty and Parts Support

FIMCO Industries is one of the largest sprayer manufacturers in the United States, which means replacement pumps, nozzles, and boom parts are easy to source. The 2-year consumer warranty covers pump and component failures, and FIMCO has a reputation for honoring claims without hassle.

5. Master Mfg 24-Gallon Deluxe Pull-Behind Trailer Broadcast Sprayer

The Master Mfg 24-Gallon Deluxe Sprayer sits in the middle of the Master Mfg lineup, between the 25-gallon economy model and the 36-gallon premium rig. I see it as the balanced choice for 2 to 3 acre properties. The 2.2 GPM Everflo pump matches the NorthStar output, and the four quick-attach nozzles deliver a clean 7-foot swath.

The pressure regulating system is the standout feature here. It keeps nozzle output consistent even as the battery voltage dips during a long session, which means your application rate stays even from the first pass to the last. That matters more than most people realize for herbicide effectiveness.

The low center of gravity is a real benefit on side slopes. Where taller tank carts get tippy, this squat design tracks straight even with a partially full tank sloshing. The 13-inch heavy-duty tires handle pasture and rough lawn without bouncing the boom.

The 52-percent 5-star rating reflects a solid but not spectacular reception. With only 20 reviews the sample is small, but the 2-year manufacturer warranty and the Everflo pump pedigree suggest long-term reliability.

Pressure Regulation Benefits

The pressure regulating system maintains constant PSI at the nozzles regardless of pump output fluctuations. This matters because inconsistent pressure means inconsistent droplet size, which leads to streaky application. If you spray herbicides where uniform coverage affects results, this feature is worth paying for.

Storage and Transport

The boom folds in for storage, compressing the rig to a manageable footprint. At 58 pounds empty, it is light enough for one person to wheel into a shed. The 15-foot hose and included spot spray gun store neatly on the frame.

6. Grass Guardian 25-Gallon Pull-Behind Trailer Broadcast Sprayer

The Grass Guardian 25-Gallon Sprayer is the value play if you want 25-gallon capacity without paying for a high-output pump. You get the same tank size as the FIMCO and Chapin 25-gallon models, but at a lower price. The trade-off is the 1.1 GPM Everflo pump, which is fine for light residential use but slower for big jobs.

I tested the 7-foot broadcast swath and it covers a respectable strip per pass. The shut-off valve lets you kill flow to the boom and switch entirely to the spot spray gun, which reaches 20 feet horizontally. The 15-foot rubber hose with organizing strap keeps things tidy between uses.

The 10-inch pneumatic tires handle typical lawn terrain without issue. The 12V alligator clamp harness with power switch is standard for this category, and the unit hitches to zero turn mowers, ATVs, and UTVs without adapters.

The 4.0-star average across 83 reviews is decent for a newer product. The translucent tank with raised volume markings is a nice touch that helps you mix accurately. Prime eligibility is a real advantage here since several competitors ship slowly.

Pump Output Limitations

The 1.1 GPM pump output means this sprayer works best at slower tow speeds. If you try to spray at 5 mph or faster, the nozzles may not atomize fully, leaving you with larger droplets and uneven coverage. Slow down to 2 to 3 mph for best results.

Tank Capacity and Refill Frequency

A full 25 gallons covers roughly three-quarters of an acre at typical application rates. That is enough for most residential lawns in a single fill. For properties over 2 acres, plan on at least one refill stop mid-job.

7. Chapin 97600 15-Gallon EZ Tow Dripless Sprayer

The Chapin 97600 is the older sibling of the 97714, and it has been on the market long enough to accumulate 233 reviews. The 15-gallon tank is a good middle-ground size for residential lawns in the 1 to 2 acre range. The 12V diaphragm pump runs quiet and the dual filtration system extends pump life by catching debris before it reaches the nozzles.

The standout feature is the professional dripless shut-off with Comfort Grip lock. Once you release the trigger, the shut-off seals immediately with no after-drip. That matters for herbicide work where a few stray drops can brown a stripe across your lawn.

The 15-foot reinforced hose and 7-foot boom give you both broadcast and spot spray options. The brass extension wand is a nice upgrade over the all-poly wands on cheaper units. The steel frame trailer with pneumatic tires tows smoothly behind lawn tractors and ATVs.

The 3.8-star average is the concern here. With 14 percent 1-star reviews, there are real reports of pump failures and fitting leaks. Chapin stands behind the product, but you should expect to do some maintenance over the life of the unit.

Pump Reliability Over Time

The diaphragm pump is self-priming and has no shaft seals to replace, which is good for longevity. The trade-off is that diaphragm pumps eventually need a diaphragm replacement, typically after 2 to 3 seasons of regular use. Keep a rebuild kit on hand for the second season.

Dripless Shut-Off Value

The dripless shut-off is not a gimmick. Standard shut-offs can release a tablespoon of chemical after you release the trigger, which over a full lawn creates visible streaks. The Chapin system eliminates that, giving you cleaner edges around sidewalks and beds.

8. Brinly ST-251BH-A 25-Gallon Self-Storing Tow Behind Sprayer

Brinly is a name lawn tractor owners know, and the ST-251BH-A brings their self-storing design to a 25-gallon capacity. The collapsible swing-away booms fold tight for storage and for passing through garden gates, which solves one of the biggest complaints about fixed-boom sprayers. The in-line mounted tank keeps the center of gravity low.

The Ultra Lo-Drift spray tips are the feature that sets this Brinly apart. Standard flat fan nozzles produce fine droplets that drift in even light wind. The Lo-Drift tips produce larger droplets that stay on target, which matters for herbicide work near desirable plants.

I like the 12-foot spray hose with ergonomic thumb control. The thumb control is easier on your hand than a squeeze trigger during long sessions, and the adjustable nozzle lets you dial in from stream to mist. The 25-gallon poly tank will not dent or rust.

The 4.0-star average across 48 reviews is solid, and the 2-year warranty plus USA manufacturing add value. The catch is availability, with only single units in stock at times. If you see it available, do not wait.

Lo-Drift Tip Advantages

Drift is the silent killer of herbicide effectiveness. When wind carries your spray off target, you waste chemical and risk damaging ornamentals. The Ultra Lo-Drift tips reduce drift by producing larger droplets that fall faster, letting you spray in conditions where standard nozzles would force you to stop.

Self-Storing Design

The collapsible boom and vertical storage orientation compress the sprayer to a small footprint when not in use. If your shed or garage is tight, this is one of the few 25-gallon tow behinds that tucks into a corner without monopolizing floor space.

9. Brinly ST-152BH-A 15-Gallon Self-Storing Tow Behind Sprayer

The Brinly ST-152BH-A is the 15-gallon version of the self-storing design, aimed at smaller lawns where a 25-gallon tank is overkill. The collapsible break-away booms snap back if they hit an obstacle, and the vertical storage footprint of just 19 by 24 inches makes this the easiest tow behind to store.

The 1 GPM pump with 40 PSI is modest but adequate for the 15-gallon tank size. The dual filtration system catches debris at two points, which extends pump life and reduces clog stops mid-job. The translucent tank with oversized screw cap makes filling and mixing easy.

For 1-acre lawns with tight landscaping, this Brinly is a smart choice. The break-away booms let you weave through garden gates and around retaining walls where a fixed boom would catch. The 2-year warranty matches the larger Brinly model.

The 4.0-star rating across 128 reviews reflects consistent satisfaction. The main limitation is the small tank, which means more refills on bigger properties. Pair this with a dedicated 12V battery if you spray for more than 30 minutes at a stretch.

Storage Footprint Comparison

The 19-by-24-inch storage footprint is roughly half the floor space of a standard tow behind sprayer. If you park your mower in the same shed as your sprayer, that difference matters every time you walk past it. The vertical orientation also keeps the boom protected from accidental bumps.

Pump and Filtration System

The dual filtration system uses a screen at the fill opening and a secondary filter inline before the pump. This catches grass clippings and debris that would otherwise clog nozzles. The 1 GPM output is enough for the boom but slow for the spot gun on long-reach work.

10. Ironton 13-Gallon Tow-Behind Broadcast and Spot Sprayer

The Ironton 13-Gallon Sprayer is the lightest full-featured tow behind on this list at just 29.4 pounds empty. That makes it easy to lift on and off a truck bed or hang on a wall bracket for storage. The 13-gallon tank hits a sweet spot for small to medium lawns where a 25-gallon rig is overkill.

I appreciate the practical details. Gallon marks are molded directly into the translucent tank, so you can see exactly how much liquid you have without guessing. The 7.5-inch fill opening is wide enough to pour from a jug without a funnel, and the bottom drain empties the tank completely for winterization.

The 1 GPM Ironton pump uses chemical-resistant components and is explicitly approved for use with Roundup agricultural herbicide. That approval matters if you use professional-grade chemicals that degrade cheaper pump seals. The pump runs off a 12V battery with alligator clamps.

The 4.2-star average across 522 reviews is one of the strongest ratings on this list. The main limitation is flow rate, which means slower application. For small properties where speed is less important, the Ironton is a reliable choice.

Chemical Compatibility

The UV-resistant poly tank is compatible with virtually all common pesticides, herbicides, and fertilizers. The explicit Roundup agricultural approval means the seals and pump components can handle glyphosate formulations that would degrade cheaper rubber seals. Always rinse thoroughly after use regardless of tank material.

Weight and Maneuverability

At 29.4 pounds empty, this is the lightest sprayer here and easy for one person to maneuver. The trade-off is that lighter weight means less stability when the tank is full on uneven ground. Stick to relatively flat terrain for the smoothest results.

11. Master Mfg 25-Gallon Deluxe Lawn Pull-Behind Broadcast Sprayer

The Master Mfg 25-Gallon Deluxe Lawn Sprayer is the mid-tier Master Mfg offering, positioned between the 24-gallon and 36-gallon models. The 2.2 GPM Everflo pump with pressure regulating system gives you solid output for the 7-foot broadcast swath. Dual deflector nozzles provide adjustable coverage width.

The spot spray gun is one of the strongest here, reaching 25 feet vertically and 30 feet horizontally. That reach lets you hit tree canopies and ditch banks without leaving the seat. The 25-gallon tank is a good size for 1 to 2 acre properties.

The unit hitches to zero turn mowers, ATVs, and UTVs, which covers most tow vehicles. Master Mfg explicitly recommends it for small to medium lawns, food plots, and waterways in the 1 to 2 acre range.

The 3.7-star average is the lowest on this list, dragged down by 16 percent 1-star reviews. Common complaints focus on pump reliability and boom nozzle fitment. The 1-year warranty on pumps and components is shorter than the 2-year coverage on the premium Master Mfg models.

Pump Reliability Concerns

The 16 percent 1-star rate is a flag. Most negative reviews cite pump failures within the first season. If you buy this unit, flush the pump thoroughly after each use and store it where it will not freeze. A pump rebuild kit is inexpensive insurance for the second season.

Ideal Property Size

Master Mfg rates this sprayer for 1 to 2 acre properties, which matches our testing. The 25-gallon tank covers roughly three-quarters of an acre per fill at standard rates. For larger properties, step up to the 36-gallon premium model.

12. Chapin 97714 25-Gallon Tow-Behind ATV and UTV Sprayer

The Chapin 97714 is the premium Chapin offering, and it brings the highest flow rate on this list at 2.5 GPM. The 3-stage filtration system is the most comprehensive here, with a filter basket in the fill cap, an in-tank filter, and a filter at the shut-off. If you use wettable powders that clog cheaper systems, this is the sprayer to beat.

Made in the USA at Chapin’s Batavia, New York facility, this unit comes with US-based customer service and technical support. The heavy-duty powder-coated steel trailer rides on 12-inch pneumatic tires that handle uneven ground without complaint.

The 19-inch poly wand with 180-inch reinforced PVC hose gives you solid reach for spot spraying. The adjustable poly cone nozzle lets you switch between cone and stream patterns. The 2-nozzle spray boom delivers a 7-foot pattern with adjustable height to clear tall grass.

The 3.6-star average is the lowest here, with 20 percent 1-star reviews. Common complaints focus on the boom mounting hardware and pump switch durability. The 1-year warranty is shorter than the Brinly and Master Mfg premium offerings.

Filtration for Wettable Powders

Wettable powder herbicides are notorious for clogging sprayer lines. The Chapin 3-stage filtration catches powder clumps at three points, keeping you spraying instead of stopping to clear clogs. If you use powdered chemicals regularly, this filtration system justifies the higher price.

Weight and Tow Stability

At 60 pounds empty, this is the heaviest sprayer on the list. That weight provides stability when the tank is full, but it makes the unit harder to load and unload solo. The heavy-duty steel frame is built for years of use but plan for two people when moving it.

How to Choose the Best Tow Behind Sprayer?

Choosing among the best tow behind sprayers comes down to four factors: tank capacity, pump output, spray configuration, and tow vehicle compatibility. Get these four right and you will be happy with your purchase for years. Get them wrong and you end up with a sprayer that is too small, too slow, or incompatible with your mower.

Tank Capacity and Property Size

Tank size should match your property. For lawns under 1 acre, a 12 to 15 gallon tank is plenty. For 1 to 3 acre properties, step up to a 21 to 25 gallon tank. Pasture and agricultural use over 3 acres calls for a 36 gallon or larger tank to minimize refill stops.

The general rule is that one gallon covers about 1,000 square feet at typical application rates. That means a 25-gallon tank covers roughly 25,000 square feet, or just over half an acre, per fill. Use this as a baseline to calculate how many refills you will need for your property.

Pump GPM and Pressure

GPM, or gallons per minute, determines how fast you can spray and how wide a boom you can run. A 1.0 to 1.1 GPM pump is fine for small tanks and spot spraying. For boom spraying across 7 feet or more, look for 2.0 GPM or higher. The 3.0 GPM Master Mfg pump is the strongest here and keeps a 10-foot swath fully pressurized.

Pressure matters for atomization. Higher PSI produces finer droplets, which improves coverage but increases drift risk. Most residential sprayers run 40 to 70 PSI, which is a good balance for lawn and pasture work.

Boom Versus Boomless Sprayers

This is the most common question in lawn care forums, so let me break it down clearly.

Boom sprayers use a horizontal bar with multiple nozzles to deliver a wide, even spray pattern. They give you precise edge definition and consistent application rates. The trade-off is that the boom is vulnerable to snagging on trees, fences, and posts. Boom sprayers are best for open lawns and fields with few obstacles.

Boomless sprayers use a single deflector nozzle or a pair of nozzles to throw spray outward without a physical boom. They are more durable because there is nothing to snag, and they work well in rough terrain and around obstacles. The trade-off is less precise edge control and more drift in wind. Boomless sprayers are best for pastures, ditches, and rough ground.

Most models on this list offer both modes: a boom for open areas and a spot spray gun for targeted work. That dual capability gives you the best of both worlds for typical residential and small farm use.

Tow Vehicle Compatibility

Every sprayer on this list uses a standard pin hitch that fits lawn tractors, ATVs, UTVs, and most zero turn mowers. The key consideration is battery capacity. Most 12V sprayer pumps draw 5 to 8 amps, which adds up over a long session.

Forum users consistently recommend adding a dedicated 12V battery for your sprayer to avoid draining your mower or ATV battery. A small motorcycle or lawn tractor battery mounted on the sprayer frame lets you run independently and recharge between uses.

Coverage Calculator: How Many Acres Will X Gallons Spray

Here is a practical coverage reference based on standard application rates of 1 to 2 gallons per 1,000 square feet.

A 12-gallon tank covers roughly 0.3 to 0.5 acres per fill. A 15-gallon tank covers 0.4 to 0.6 acres. A 21-gallon tank covers 0.5 to 0.8 acres. A 25-gallon tank covers 0.6 to 1.0 acres. A 36-gallon tank covers 0.9 to 1.5 acres.

To calculate your needs, divide your property square footage by the coverage per gallon at your chosen application rate. For a 2-acre lawn at 1 gallon per 1,000 square feet, you need about 87 gallons total, which means three to four refills of a 25-gallon tank.

Maintenance and Winterization

Flush your sprayer with clean water after every use, especially when switching between herbicides and fertilizers. Residual chemicals can react and create sludge that clogs pumps and nozzles. Run clean water through the pump, boom, and spot gun until the output runs clear.

Before freezing weather, drain the tank completely and run RV antifreeze through the pump and lines. Water left in the pump will freeze, expand, and crack the housing. Store the sprayer with the tank empty and the boom protected from accidental bumps.

FAQs

Final Thoughts on the Best Tow Behind Sprayers

After comparing all 12 models, our top recommendation remains the NorthStar 21-Gallon Tow-Behind Boom Sprayer for its commercial-grade pump, breakaway boom, and proven long-term reliability. It hits the sweet spot of capacity, output, and durability that works for most property owners.

For larger properties, the Master Mfg 36-Gallon Premium Sprayer with its 3.0 GPM pump and 10-foot swath is worth the extra investment. And for small lawns or ATV owners on a budget, the Homestead 12-Gallon Sprayer delivers the essentials without overpaying.

The best tow behind sprayers in 2026 are the ones that match your property size, your tow vehicle, and your spraying workload. Use the coverage calculator and the boom versus boomless guidance above to narrow your choice, and you will have a sprayer that serves you for years.
