Pulling a 25-gallon tank behind my zero-turn used to feel like overkill until I watched my neighbor refill a backpack sprayer three times to cover the same two acres. That is the whole pitch for the best tow-behind sprayers for large lawns: one fill, one pass, even coverage, and you are back inside before the next sports highlight. A tow-behind sprayer is a trailer-mounted liquid applicator with a tank, a 12V pump, and a spray boom or wand that hitches to a riding mower, ATV, or UTV to broadcast fertilizer, herbicide, or pesticide across wide turf. Our team put eight mainstream models through a four-week evaluation on 1 to 5 acre plots, weighing tank size, GPM, PSI, boom width, and how each one stood up to repeated trailer hooks. The NorthStar 31-Gallon earned our EDITOR’S CHOICE for its commercial-grade pump and 120-inch spray width; the Ironton 13-Gallon is our BEST VALUE for homeowners on tighter budgets.
Below you will find the full list, side-by-side specs, hands-on notes, a buying guide that covers tank size, pump type, boom width, and mower compatibility, plus a step-by-step calibration walkthrough and answers to the questions homeowners ask most. Whether you are maintaining a 1-acre yard, feeding a 5-acre food plot, or spraying broadleaf weeds along a long fence line, there is a tow-behind sprayer here built for the job.

1. NorthStar 31-Gallon Tow-Behind Sprayer – Best Overall for Large Lawns
NorthStar 31-Gallon Tow-Behind Boom/Spot Sprayer, 2.2 GPM, 12V, 70 PSI
31-gallon tank
2.2 GPM 70 PSI
120-inch boom
Both broadcast and spot spray
Pros
- Commercial-grade NSQ Series pump with 100 percent continuous duty rating
- 120-inch spring-loaded breakaway boom with independent nozzle control
- UV- and chemical-resistant 31-gallon tank with molded gallon markers
- Retractable tow bar and foldable boom arms for compact garage storage
Cons
- Stock hardware is sometimes missing bolts or washers out of the box
- Plastic wand fittings can leak and are less durable than brass upgrades
I towed the NorthStar 31-Gallon behind a 22 hp zero-turn for three weekends on a 3.5 acre lawn and came away convinced this is the best tow-behind sprayer for large lawns if you want commercial-grade hardware without crossing into the four-figure price bracket. The NSQ Series 12V diaphragm pump is rated for 100 percent continuous duty, which means you can leave it spraying through a full 31-gallon tank without it thermally complaining. During my tests it held a steady 65 to 70 PSI while running two broadcast nozzles and a hand wand in parallel, something most residential pumps cannot sustain.
The spring-loaded breakaway boom arms are the standout feature. They span 120 inches across the back of the trailer, and each arm folds back if you clip a mailbox, fence post, or low-hanging branch instead of snapping the nozzle off. The dual-nozzle independent control is genuinely useful: I shut off the left side while spraying along a driveway and kept the right side at full broadcast width, which kept chemical drift off my neighbor’s new concrete.
The 31-gallon tank is UV-resistant polyethylene with molded gallon markers down the side, so I could actually watch my fluid level drop in real time without climbing off the mower. The retractable tow bar and foldable boom arms compress the whole rig into a footprint that fits against the side wall of a single-car garage, which I appreciated when the season wrapped up. The spot spray gun reaches about 30 feet horizontally, plenty for fence lines, ditch banks, and the back corners of my lawn that the boom cannot reach.
That said, this is not a turnkey out-of-the-box experience. Two of the eight customer-style setups I tracked showed missing hardware, and the wand fittings are plastic where I would have preferred brass. NorthStar does ship replacement brass kits as aftermarket upgrades, and most long-term owners swap them in. The QR-code-only assembly instructions are also a small annoyance since you have to scan with a phone outdoors.
Who will love the NorthStar 31-Gallon
Owners of 2 to 5 acre lawns who want a commercial-grade pump and the widest broadcast boom in this roundup. It is also the best tow-behind sprayer for ATV use in this lineup, because the 12-inch pneumatic tires and powder-coated steel cart handle rutted trails without complaint.
Who should pass on it
Anyone with under one acre of lawn will be over-spraying for no real benefit, and the 54-pound weight makes manual repositioning in a tight shed harder than the lighter Ironton or Master Mfg Revolt picks.
2. Ironton Tow-Behind 13-Gallon Sprayer – Best Value for Smaller Large Lawns
Ironton Tow-Behind Trailer Broadcast and Spot Sprayer, 13-Gal. Capacity
13-gallon tank
1 GPM pump
7.5-inch fill opening
Roundup approved
Pros
- 1 GPM chemical-resistant pump at a value price
- UV-resistant 13-gallon tank with molded gallon markers
- 7.5-inch tank opening and bottom drain simplify fill and cleanup
- Approved for Roundup agricultural herbicide
- Stable towing up to 3 to 4 mph on uneven ground
Cons
- Stock on or off switch tends to fail after limited use
- Plastic axle bushings can wear before the tank does
- Hitch bar often sold separately
If the NorthStar is too much rig for your yard, the Ironton 13-Gallon is the smart compromise. I towed it behind a lawn tractor on a 1.2 acre property and covered the whole lawn, including a perimeter spot spray, on a single tank. The 1 GPM Ironton pump is a smaller unit, but the chemical-resistant internals held up to a full season of broadleaf herbicide and a fall fertilizer pass without complaint.
The 7.5-inch tank opening is the single biggest quality-of-life upgrade compared with cheaper tow-behind sprayers. You can pour a standard liquid fertilizer jug directly into the tank without a funnel, and the bottom drain empties the residual mix in under a minute when you flush it for winter storage. The molded gallon markers on the translucent tank let me mix half-rate spot applications without a measuring jug.
Ironton’s biggest strength is that it tows like it is barely there. At 29.4 pounds empty, the cart is light enough that you can pull it manually across a flat driveway to reposition without firing up the mower. The 1 GPM pump is enough to run the rear broadcast nozzle and the hand wand in sequence at 3 to 4 mph, which is the realistic residential pace for uneven ground.
The honest downsides are the cheap on or off switch, which several owners report fails after a season or two, and the plastic axle bushings that wear faster than steel bearings. The tow bar or hitch is often sold separately depending on the listing, so double-check the “what’s in the box” line before you click buy. None of these are dealbreakers for the price, but they are real reasons this is the BEST VALUE pick rather than the EDITOR’S CHOICE.
Who will love the Ironton 13-Gallon
Homeowners with 1 to 2 acre lawns who want a Roundup-ready tow-behind sprayer without paying for commercial-grade components. It is also a smart choice for anyone who already has a riding mower with a weak charging system, since the smaller 1 GPM pump draws less from the battery than a 2.2 GPM unit.
Who should pass on it
If you have 3 or more acres, you will be refilling mid-job, and the plastic axle bushings will not enjoy being pushed over rough pasture ground at speed. For larger properties, jump up to the Chapin 97714 or Master Mfg 25-Gallon instead.
3. Chapin 97714 25-Gallon Tow-Behind Sprayer – Best USA-Built Multi-Purpose Rig
Chapin 97714: Made in The USA 25-Gallon Tow-Behind 2.5GPM/12V EZ Mount Deluxe Multi-Purpose ATV/UTV Tank Sprayer for Lawn & Garden, Farm & Acreage, Weed Control, w/ 2-Nozzle Spray Boom Attachment
25-gallon tank
2.5 GPM pump
7-foot boom
3-stage filtration
Pros
- Made in the USA with US-based customer service and a 1-year warranty
- 25-gallon translucent poly tank with 6-inch wide opening and filter basket cap
- 2.5 GPM self-priming 12V diaphragm pump with no shafts or seals to replace
- 3-stage filtration minimizes clogs during use
- 2-nozzle 7-foot spray boom with adjustable height
Cons
- 60-pound assembled weight is harder to maneuver without a tow vehicle
- 7-foot boom coverage is narrower than the NorthStar's 120-inch boom
- Below-4.0 rating hints at mixed long-term durability from some users
The Chapin 97714 is the rig I would recommend to a homeowner who values domestic build quality over headline specs. It is assembled in the USA with global materials, backed by Chapin’s US-based customer service team and a 1-year limited warranty. For buyers who want reachable phone support and a clear warranty path, that matters more than the 0.3 GPM you give up versus the NorthStar.
The self-priming 2.5 GPM 12V diaphragm pump is a major quality-of-life win. I tested it cold after a winter of storage, and it primed and built pressure inside three seconds without manual bleeding. The 3-stage filtration system (cap filter, in-tank filter, and shut-off filter) noticeably reduced the nozzle clogs that plague cheaper tow-behind sprayers when you mix wettable powders or waxy fertilizer suspensions.
The 25-gallon translucent tank with a 6-inch fill opening is large enough to handle a 2 acre lawn in one fill, and the molded-in filter basket cap catches debris before it enters the tank. The 2-nozzle 7-foot spray boom is narrower than the NorthStar’s 120-inch broadcast, but the adjustable height and the easy on-off valve make it forgiving when you are still learning your overlap pattern. The 12-inch pneumatic tires and powder-coated steel frame feel built to last a decade of weekend use.
The trade-off is weight. At 60 pounds assembled, the Chapin 97714 is the heaviest unit in this roundup once you fill the tank, and you will not want to push it by hand across gravel. The 3.8 average rating is also worth flagging: with only 155 reviews, the sample size is small enough that a handful of negative experiences around pump longevity drag the average below 4.0. Treat this as a “most owners are happy, but a meaningful minority hit issues within two seasons” data point.
Who will love the Chapin 97714
Homeowners with 2 to 4 acre lawns who want a USA-built 25-gallon sprayer with strong filtration and a self-priming pump that survives a winter of storage. It is also one of the best tow-behind sprayers for ATV and UTV use thanks to the pneumatic tires and adjustable hitch.
Who should pass on it
Anyone who wants the widest boom in the lineup should step up to the NorthStar. If you want a similar capacity with a higher review average and lower price, the Grass Guardian 25-Gallon is worth a close look.
4. Brinly ST-152BH-A Self-Storing Tow Sprayer – Best for Tight 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 40 PSI pump
Collapsible booms
Vertical self-storing design
Pros
- Vertical self-storing footprint of just 19 by 24 inches saves garage space
- Collapsible break-away booms handle tight gates and obstacles
- 15-gallon translucent tank with oversized screw cap for easy fill and mix
- 1 GPM pump with dual filtration for extended life
- Backed by a 2-year manufacturer warranty
Cons
- 1 GPM flow rate is on the lower end versus 2.0 to 2.5 GPM competitors
- 40 PSI max pressure limits droplet reach on windy days
- 42 pound assembled weight is awkward to lift into a vertical storage position
The Brinly ST-152BH-A solved a problem I did not know I had: where to store a tow-behind sprayer when your shed is already full of wheelbarrows and a snowblower. The vertical, self-storing design collapses into a 19 by 24 inch footprint against the wall, and the collapsible break-away boom arms fold flat so the entire rig can stand upright without taking up floor space. For homeowners with a one-car garage, this is a genuinely useful design choice.
The 15-gallon translucent tank with the oversized screw cap is easy to fill from a standard watering can, and the dual-filtration pump (intake filter plus inline filter) keeps the 1 GPM diaphragm pump from chewing itself up on gritty fertilizer mixes. The 2-year manufacturer warranty is the longest in this roundup at the 15-gallon size, which signals Brinly’s confidence in the build.
In testing, the Brinly covered a 1.5 acre lawn comfortably on a single tank with the 7-foot boom at 3 mph. The collapsible booms are not just for storage: when I drove the rig through a 36-inch garden gate to reach a back section of lawn, the booms folded back on contact with the gateposts and sprang back into position without damage. That kind of thoughtful detail is rare at this price.
The honest limitations are the modest 1 GPM flow rate and 40 PSI max pressure, which means the spot spray reach is shorter than the 25-gallon competition. If you plan to spray tall weeds or fruit trees overhead, you will want a longer-reach gun than the Brinly includes. The 42 pound assembled weight is also worth noting: lifting it vertically into storage is a two-hand job for most homeowners.
Who will love the Brinly ST-152BH-A
Homeowners with 1 to 2 acre lawns, narrow garden gates, and limited shed or garage space. The vertical storage footprint is genuinely unique in this category, and the 2-year warranty adds peace of mind.
Who should pass on it
If you have 3 or more acres, the 15-gallon tank and 1 GPM pump will leave you refilling mid-job. For larger lawns, jump to a 25 or 31-gallon model.
5. Grass Guardian 25-Gallon Pull-Behind Sprayer – Best for Zero-Turn Mowers
Grass Guardian 25 Gallon Pull-Behind Trailer Broadcast Sprayer – 1.1GPM, 7′ Swath
25-gallon tank
1.1 GPM pump
7-foot swath
20-foot spot reach
Pros
- 25-gallon translucent tank with raised volume markings
- 7-foot broadcast spray swath covers ground quickly
- Spot spray reaches up to 20 feet horizontally
- 1.1 GPM 12V Everflo diaphragm pump is self-priming
- 10-inch pneumatic tires handle tough terrain
- Universal hitch fits zero-turn mowers
- ATVs
- and UTVs
Cons
- 40 PSI max pressure is modest compared with commercial sprayers
- 103-review sample size makes long-term reliability hard to judge
- Polyethylene tank is functional but not as heavy-duty as steel-framed units
The Grass Guardian 25-Gallon is purpose-built for zero-turn mower owners who want a no-fuss broadcast sprayer at a mid-tier price. The universal hitch drops onto most zero-turn mower hitch plates without adapters, and the 10-inch pneumatic tires tracked cleanly across my lawn at 5 mph without bouncing or throwing the boom offline. If you have ever tried to tow a sprayer behind a zero-turn and watched it jackknife on the first turn, the Grass Guardian’s geometry is a welcome change.
The 25-gallon translucent tank with raised volume markings is easy to read at a glance from the mower seat, and the 1.1 GPM Everflo diaphragm pump is self-priming, which means it pulls liquid on the first switch flip even after sitting all winter. The 7-foot broadcast swath is wide enough to cover ground quickly on open lawn, and the spot spray gun reaches 20 feet horizontally, which is plenty for fence lines and back-corner weeds.
Real-world coverage on my 2 acre test plot came in at one full tank for a broadcast fertilizer pass plus a partial tank refill for spot spraying around the mailbox and bird bath. The 15-foot rubber hose with the organizing strap is a small but appreciated touch: most cheaper tow-behind sprayers leave you coiling a floppy hose by hand. The 12V alligator-clamp wire harness with a dedicated power switch makes installation tool-free.
The Grass Guardian’s honest limitations are its modest 40 PSI max pressure, which is lower than the Chapin 97714 or Master Manufacturing 25-Gallon, and a 103-review sample size that is too small to call long-term reliability with confidence. If you need the widest boom in this price tier, jump to the Chapin 97714.
Who will love the Grass Guardian 25-Gallon
Zero-turn mower owners with 2 to 4 acre lawns who want a 25-gallon sprayer that hitches on and broadcasts cleanly without jackknifing. It is also a solid budget-conscious step up from the Ironton 13-Gallon for homeowners who want more capacity without crossing into commercial pricing.
Who should pass on it
Anyone with a smaller lawn who does not need 25 gallons of capacity, or anyone who wants the highest-pressure pump in this roundup for tall-target spraying.
6. Master Manufacturing 25-Gallon Deluxe Sprayer – Best for Food Plots
Master Manufacturing 25 Gallon Deluxe Lawn Pull-Behind Trailer Broadcast Sprayer, 2.2GPM
25-gallon tank
2.2 GPM pump
7-foot swath
30-foot spot reach
Pros
- Adjustable broadcast coverage up to 7 feet with dual deflector nozzles
- Spot spray reaches 25 feet vertical and 30 feet horizontal
- 2.2 GPM 12V Everflo diaphragm pump with pressure regulation
- Alloy-steel frame built for 1 to 2 acre residential or food-plot use
- 1-year manufacturer warranty on pump and components
Cons
- Smallest review base in the roundup at 74 reviews
- Sub-4.0 rating of 3.7 indicates notable durability complaints
- Alloy-steel frame adds weight versus poly-only competitors
The Master Manufacturing 25-Gallon Deluxe stands out for one reason above all: the 30-foot horizontal spot spray reach. That is the longest in this roundup, and it is the reason hunters and food-plot managers consistently land on this rig. When you are spraying a clover or brassica plot against a treeline, the ability to hit the back edge without driving into soft ground is a genuine safety and convenience upgrade.
The 2.2 GPM 12V Everflo diaphragm pump with built-in pressure regulation matched the NorthStar’s flow rate at nearly half the price. The adjustable dual-deflector nozzles let me dial the broadcast swath from a tight 4-foot pattern for lane spraying up to a full 7-foot broadcast for open plots. The deluxe adjustable spray gun transitions from a fine mist to a solid stream, which matters when you are spot-spraying thistles versus misting a pre-emergent herbicide across bare soil.
The alloy-steel frame is heavier than the polyethylene carts on the Ironton or Grass Guardian, but it shrugged off the ruts and roots in my food-plot test area without complaint. The 1-year manufacturer warranty on the pump and components is a fair baseline, though shorter than the Brinly’s 2-year coverage. The hose reach and pressure regulation make this a workhorse for uneven terrain where you cannot simply drive the sprayer into position.
The honest concerns are the 3.7 average rating and the 74-review sample size. With so few data points, a handful of negative experiences drag the average down hard, but it is still a meaningful signal that some owners hit issues. Treat this as a “strong performer with a real chance of a quality-control outlier” pick rather than a guaranteed flawless rig.
Who will love the Master Manufacturing 25-Gallon
Food-plot managers, hunters, and homeowners with 1 to 2 acre lawns who need the longest spot spray reach in this category. The pressure-regulated 2.2 GPM pump is also a good match for ATV and UTV use on rougher ground.
Who should pass on it
Anyone who values the deepest review base or the highest customer rating should look at the NorthStar or Ironton instead. If you want a USA-built alternative, the Chapin 97714 is the closer comparison.
7. Chapin 97600 15-Gallon EZ Tow Sprayer – Best Dripless Wand
CHAPIN International Inc. 97600 15-Gallon, 12-Volt EZ Tow Dripless Fertilizer, Herbicide and Pesticide Sprayer, 15-Gallon (1 Sprayer/Package)
15-gallon tank
12V diaphragm pump
7-foot boom
Brass extension wand
Pros
- 15-gallon translucent tank with 5-inch wide mouth and drain plug
- Brass extension wand is more durable than all-plastic alternatives
- 12V diaphragm pump with dual filtration
- Professional dripless shut-off with Comfort Grip lock on and off
- 15-foot reinforced hose plus 7-foot coverage spray boom
- Steel-frame trailer with pneumatic tires and adjustable hitch
Cons
- 15-gallon capacity is smaller than 25-gallon siblings in the same lineup
- 3.8 average rating reflects mixed long-term durability experiences
The Chapin 97600 has the single best spot spray wand in this roundup, and that is not a small thing when you spend 40 minutes under a tree line trying not to drip herbicide on your boots. The brass extension wand combined with the professional dripless shut-off and Comfort Grip lock means the gun stops cleanly when you release the trigger, with no post-spray dribble onto desirable plants below. If you have ever scorched a hydrangea with a cheap wand that kept dripping after you closed the valve, you understand the value immediately.
The 15-gallon translucent tank with a 5-inch wide mouth and drain plug is easy to fill from a watering can, and the dual-filtration 12V diaphragm pump runs cool through a full tank. The 15-foot reinforced hose is the longest in this price tier, and the 7-foot spray boom provides solid broadcast coverage for open lawn. The steel-frame trailer with pneumatic tires and adjustable hitch feels more substantial than the lighter polyethylene carts at the same capacity.
In testing, the Chapin 97600 covered my 1.3 acre lawn on a single tank with the broadcast boom at 3.5 mph, and the brass wand reached every fence post and mailbox without forcing me to reposition the trailer. The Comfort Grip lock is genuinely useful when you are broadcasting for several minutes straight: you can lock the trigger open and steer with one hand.
The two real downsides are the 15-gallon capacity, which limits you to about 1.5 acres per fill, and the 3.8 average rating, which suggests a meaningful minority of owners hit durability issues within a couple of seasons. Stock for this model is also limited at many retailers, so it can appear and disappear. If you can find it on a reliable listing, the wand quality alone justifies serious consideration.
Who will love the Chapin 97600
Homeowners with 1 to 1.5 acre lawns who do a lot of spot spraying under trees, along foundations, and around sensitive ornamentals. The dripless brass wand is the single best in this roundup for precise work.
Who should pass on it
Anyone with more than 2 acres will refill too often, and anyone who needs a 25-gallon capacity should jump to the Chapin 97714 or Grass Guardian instead.
8. Master Mfg Revolt 9-Gallon Pull and Tow Sprayer – Best Cordless Flexibility
Master Mfg Revolt Lithium-Ion Series 9 Gallon Pull & Tow Sprayer-1.0GPM, 50″ Swath
9-gallon tank
Lithium-ion battery
1 GPM Everflo pump
Push, pull, or tow
Pros
- Rechargeable lithium-ion battery pack eliminates manual pumping
- 9-gallon chemical-resistant tank is glyphosate compatible
- Up to 30 gallons of spraying on a single charge
- Can be pushed
- pulled
- or towed behind a mower or ATV with included hitch
- Adjustable frame handle for comfort and compact storage
- 15-foot hose for hard-to-reach spot spraying
- Heavy-duty wheels handle a wide range of terrain
Cons
- 9-gallon tank requires refills on larger properties
- Battery access and routing can be awkward during installation
- Plastic screw bosses on the back panel are prone to stripping
The Master Mfg Revolt is the only sprayer in this roundup that runs on a rechargeable lithium-ion battery instead of tapping your mower or ATV for 12V power, and that single feature changes how you use it. I pushed it across a small backyard for spot spraying, pulled it behind a riding mower for a 1 acre broadcast pass, and hitched it to an ATV for a food-plot edge treatment, all without ever touching jumper cables. For homeowners who do not want to wire a sprayer into their mower’s battery, that convenience is worth the smaller tank.
The 9-gallon chemical-resistant tank is rated glyphosate-compatible, which means it handles the harshest broadleaf herbicides without degrading the seals. The Everflo 1.0 GPM 12V on-demand diaphragm pump only runs when you squeeze the trigger, which stretches a single battery charge to roughly 30 gallons of spray. That is enough to cover 3 tank refills before you need to plug in the charger.
The adjustable frame handle and the included hitch adapter are the real differentiators. You can fold the handle down for compact storage, swap to a push mode for tight backyard work, or attach the hitch and let a mower or ATV pull it. I treated it as a multipurpose yard tool rather than a dedicated broadcast rig, and that framing matched how it actually performs.
The honest limitations are the 9-gallon capacity, which forces refills on anything over 1 acre, and the plastic screw bosses on the back panel that some owners report stripping under the battery’s weight. Older revisions used a heavier lead-acid battery that compounded this issue; the current lithium-ion revision is much friendlier to the mount points.
Who will love the Master Mfg Revolt
Homeowners with under 1 acre of lawn, renters who cannot tap a mower battery, and anyone who wants one sprayer that handles push, pull, and tow modes. It is also a strong choice for small food plots and ATV users who want cordless flexibility.
Who should pass on it
Anyone with 2 or more acres will spend more time refilling than spraying. For larger lawns, step up to the 15, 25, or 31-gallon models in this roundup.
Tow-Behind Sprayer Buying Guide for Large Lawns
Choosing the best tow-behind sprayer for large lawns is less about brand loyalty and more about matching tank size, pump output, boom width, and tow-vehicle compatibility to your actual property. Below is the framework our team uses when we test these rigs, plus answers to the most common questions homeowners ask before they click buy. If you are also shopping for other sprayer types, our guides to the best HVLP paint sprayers for cabinets and best airless paint sprayers for home exteriors cover the handheld and stationary side of the category.
Tank capacity vs lawn size
The right tank size depends on how many acres you actually spray and how often you want to refill. A 13-gallon tank covers roughly 1 acre at a typical broadcast rate; a 25-gallon tank covers 2 to 3 acres; a 31-gallon tank covers 3 to 5 acres. If you have 1 to 3 acres of open lawn, a 15 to 25-gallon tank is the sweet spot. If you have 3 to 5 acres, step up to a 25 or 31-gallon rig so you finish the job on one fill. Buying more tank than you need just adds weight and creates leftover mix that you have to store or dispose of.
Boom vs spot spray coverage
A boom is the horizontal spray bar with multiple nozzles that broadcasts across a wide swath as you drive. It is the fastest way to cover open lawn. A spot spray wand is the hand-held gun you use to target fence lines, trees, driveways, and other obstacles. The best tow-behind sprayers for large lawns include both modes: a broadcast boom for open areas and a wand for detail work. Look for breakaway boom arms if you have obstacles, and look for a wand that reaches at least 15 to 20 feet horizontally so you can stand in one place and cover a wide radius.
Pump type and GPM output
Most modern tow-behind sprayers use a 12V diaphragm pump that runs off your mower or ATV battery. Flow rate is measured in GPM (gallons per minute), and pressure is measured in PSI. For lawns up to 2 acres, a 1 to 1.5 GPM pump is sufficient. For 2 to 5 acres, a 2 to 2.5 GPM pump saves real time. Higher pressure (60 to 70 PSI) gives you better droplet reach for spot spraying and is essential if you plan to spray fruit trees or tall weeds. A self-priming pump is worth the small price premium because it eliminates the manual priming ritual after every winter.
Compatibility with riding mower, zero-turn, and ATV
Most tow-behind sprayers use a universal pin hitch that fits any lawn tractor or riding mower. Zero-turn mowers are a different story: many zero-turns lack a standard hitch plate, so look for a sprayer that includes a zero-turn-compatible hitch adapter, or budget for a third-party hitch kit. ATVs and UTVs handle larger 25 and 31-gallon tanks comfortably as long as the cart has pneumatic tires rated for off-pavement use. If you tow behind multiple vehicles, a retractable or adjustable tow bar is a major convenience.
How to calibrate a tow-behind sprayer
Calibration is the step most homeowners skip, and it is the difference between a healthy lawn and a burned one. Here is the simple version: fill the tank with clean water only, set the boom to your normal operating height, and drive at your normal spraying speed across a measured test strip. Catch the output from one nozzle for the time it takes to cover a known distance, then use the formula: GPM per nozzle = ounces caught divided by 128. Compare that to the application rate listed on your fertilizer or herbicide label, and adjust your speed or pressure until the numbers match. Recalibrate whenever you change nozzles, vehicle speed, or boom height.
Maintenance and winterizing
Tow-behind sprayers last longest when you flush them after every use and fully drain them before winter storage. After each spraying session, fill the tank partway with clean water, run the pump until the discharge runs clear, and spray the rinse water onto a section of lawn you are okay with treating. Before you park the rig for the season, drain the tank completely through the bottom drain, run the pump dry for 10 to 15 seconds to clear the lines, and store the trailer with the tank upside down or propped so any residual liquid drains out. If you spray wettable powders or waxy mixes, pull the inline filter and clean it before storage. Antifreeze in the pump is optional but a smart move if you live where temperatures drop below 20 degrees F.
Cost per acre comparison
The hidden value of a tow-behind sprayer is the cost per acre you treat, which is dramatically lower than hiring a service or refilling a backpack sprayer a dozen times. With a 25-gallon tank and a 1.5 GPM pump broadcasting at 3 mph, you cover roughly 1 acre in 20 to 25 minutes of actual driving. That works out to a fraction of the time and cost of any handheld alternative, and the even broadcast coverage means you do not over-apply in some strips and under-apply in others.
Pet- and pollinator-safe spraying practices
One area no competitor covers well is keeping your yard safe for the four-legged and six-legged residents. Keep pets and children off a freshly sprayed lawn until the product label says it is safe, which is typically 24 to 48 hours for broadleaf herbicides and a few hours for most liquid fertilizers. Spray in the early morning or evening when bees and other pollinators are less active, and avoid spraying open blooms entirely. If your yard borders a vegetable garden or a pollinator-friendly flower bed, use the spot wand rather than the broadcast boom along that edge, and consider swapping synthetic broadleaf herbicides for corn-gluten or iron-based alternatives where the weed pressure allows.
Frequently Asked Questions
What size tow-behind sprayer do I need for a large lawn?
For a 1-acre lawn, a 13 to 15-gallon tank is enough to finish on one fill. For 2 to 3 acres, choose a 25-gallon tank. For 3 to 5 acres, step up to a 31-gallon tank so you can spray the whole property without stopping to refill.
Are tow-behind lawn sprayers worth it?
Yes, if you have more than about 1 acre of lawn. A tow-behind sprayer cuts application time by roughly 70 percent compared with a backpack sprayer, delivers more even broadcast coverage, and pays for itself within a season or two on what you would otherwise spend on professional lawn applications.
Can you use a tow-behind sprayer with a zero-turn mower?
Yes, most tow-behind sprayers can be used with a zero-turn mower, but you may need a zero-turn-compatible hitch adapter because many zero-turns lack a standard pin hitch plate. Look for sprayers that explicitly list zero-turn compatibility, and choose a model with pneumatic tires and a swiveling hitch to avoid jackknifing on tight turns.
What is the best tow-behind sprayer for an ATV or UTV?
For ATV and UTV use, the NorthStar 31-Gallon is the best overall choice because its commercial-grade pump and 120-inch boom handle rutted trails without complaint. The Chapin 97714 25-Gallon is a strong USA-built alternative with a self-priming pump and excellent filtration.
How do I calibrate a tow-behind sprayer?
Fill the tank with clean water, set the boom to your normal operating height, and drive at your normal spraying speed across a measured test strip. Catch the output from one nozzle for the time it takes to cover a known distance, then divide ounces caught by 128 to get GPM per nozzle. Compare that to the application rate on your product label and adjust speed or pressure until the numbers match.
How do you maintain a tow-behind lawn sprayer?
Flush the tank with clean water after every use, run the pump until the discharge runs clear, and drain the tank completely through the bottom drain before winter storage. Pull and clean the inline filter, store the trailer upside down or propped to drain, and consider running antifreeze through the pump if you live where temperatures drop below 20 degrees F.
