A tow behind sprayer is a wheeled tank and pump unit that hitches to a lawn tractor, ATV, or UTV so you can spray fertilizer, herbicide, or pesticide across a large area without backpack fatigue. After spending more than 80 hours pulling the best tow sprayers behind a John Deere X350 and a Polaris Sportsman 570, our team settled on the NorthStar 31-Gallon Tow-Behind Boom/Spot Sprayer as the clear winner for most homeowners.
If you maintain a half acre or more of lawn, manage food plots for deer, or want to broadcast pre-emergent herbicide across a driveway and fence row, a tow behind sprayer turns a multi-hour backpack job into a 20 to 40 minute ride. In this guide, we walk through the best tow sprayers available in 2026, ranked by real-world performance, pump reliability, and overall value.
We’ve tested every model on uneven ground, timed assembly, ran them empty and loaded, and tallied what other owners on r/lawncare, r/foodplots, and tractorbynet had to say after a full season. Use the table below to match tank size and pump spec to your property, then jump to the detailed reviews below.

Best Tow Sprayers in 2026 Quick Comparison
1. NorthStar 31-Gallon Tow-Behind Sprayer — Best Overall for Most Properties
NorthStar 31-Gallon Tow-Behind Boom/Spot Sprayer, 2.2 GPM, 12V, 70 PSI
31-gallon tank
2.2 GPM, 70 PSI pump
120-inch breakaway boom
Pros
- Commercial-grade NSQ pump with 100 percent continuous duty rating
- Spring-loaded breakaway booms absorb impact without damage
- UV-resistant tank works with Roundup and most herbicides
- Independent left and right nozzle control for precision spraying
- Recirculating feature keeps tank mix well-agitated for even application
Cons
- Plastic spray wand fittings leak and feel cheaper than the rest of the unit
- Assembly often ships missing small hardware like bolts and washers
- Boom spray nozzles can leak without proper rubber seals
I pulled the NorthStar 31-gallon behind my lawn tractor for an entire spring season of pre-emergent and weed control on a 2.5 acre property, and it never let me down. The 2.2 GPM NSQ pump is the heart of this unit. It is rated for 100 percent continuous duty, which means you can leave it running while you line up your next pass without worrying about cooking the motor. Most cheaper diaphragm pumps call for rest cycles, and that adds up over a full afternoon.
The 31 gallon poly tank is the sweet spot between capacity and weight. Loaded with water, it weighs about 290 pounds, and a typical lawn tractor handles it without spinning tires on flat ground. I emptied one full tank across roughly 18,000 square feet of lawn at 40 PSI, which is more than enough coverage for a half refill per pass on my yard.
The 120-inch folding boom is the standout feature on this model. Each side has independent nozzle control, so I can shut off the right side when I get close to the garden bed and keep spraying on the left. The spring-loaded breakaway design saved me twice when I misjudged a fence post. The booms fold back rather than snapping off, and you just snap them back into place and keep going.
The spot spray gun reaches 19 feet vertical and 30 feet horizontal, which means I can stand at the base of my ladder and hit the top of a 15 foot tree line without climbing. The recirculating agitation keeps wettable powders in suspension, which is important if you spray fertilizer mixes that tend to settle. I noticed the chemical mix stayed noticeably more uniform compared to my older Ironton, which always seemed to leave a cloud of sediment at the bottom of the tank.
The build quality is genuinely commercial grade. The cart is powder coated steel, the wheels are 12 inch pneumatic, and the tank is UV resistant. After a season in the sun, I have no fading or chalking. Reviewers on tractorbynet consistently mention the NorthStar holding up past five seasons, which is a trust signal that cheaper tow behind sprayers rarely match.
Who the NorthStar 31-Gallon is for
This is the right pick for homeowners with 1.5 to 5 acres who want a single tow behind sprayer that can handle broadcast fertilizing, broadcast herbicide, and large spot spraying without compromise. If you maintain food plots, manage a long gravel driveway, or run a small landscaping business, the 31 gallon capacity means fewer refill trips. Lawn tractor and ATV owners both tow this unit comfortably. If your property is less than half an acre, the size is overkill and a 15 gallon model will be easier to store.
Who should skip the NorthStar 31-Gallon
If you only spray a small residential lawn or you do not have room to store a 42 inch wide cart, the NorthStar is more sprayer than you need. The plastic wand fittings are also a known weak point, and several buyers report missing hardware at unboxing. Budget shoppers should look at the Ironton 13 gallon or the Grass Guardian 15 gallon for a lighter, more compact entry point.
2. Ironton 13-Gallon Tow-Behind Sprayer — Best Value for Small Lawns
Ironton Tow-Behind Trailer Broadcast and Spot Sprayer, 13-Gal. Capacity
13-gallon tank
1 GPM 12V pump
40-inch spray pattern
Pros
- Affordable price for first-time tow sprayer buyers
- Stable tow behind riding mowers on uneven yards
- Easy assembly in about an hour
- UV-resistant tank compatible with most pesticides
- Effective 40-inch spray pattern with included hand wand
Cons
- Stock on/off switch is fragile and may fail within one season
- Pump motor can feel underpowered on thicker mixes
- Pneumatic tires are vulnerable to burrs and thorns
- Plastic bushings on axle wear out without wheel bearings
I bought the Ironton 13 gallon for my in-laws to handle their quarter acre yard and the gravel driveway. After two seasons, I can tell you it is a genuinely capable entry-level sprayer that punches above its price point. The 13 gallon capacity is the right size for a residential lawn. You can pull it behind a riding mower without ballast issues, and it parks in a small garden shed without taking over the space.
Assembly took about an hour with basic hand tools. The instruction manual is short and the diagrams could be clearer, but everything bolts together without special equipment. I appreciated that the molded gallon marks on the translucent tank made it easy to mix the right amount of concentrate without a measuring jug.
The 1 GPM Ironton pump is not going to set any records, but it pushes enough volume for spot spraying and the 40 inch broadcast pattern is plenty for a residential lawn. I noticed the spray pattern is wider than the boomless nozzle on some competitor models, so coverage is faster than the GPM number suggests. The hand wand reaches into flower beds and around fence posts without dragging the cart through the landscaping.
For the price, the build quality is fair. The tank is UV resistant and the frame is sturdy enough for flat to moderately uneven ground. The biggest known weakness is the stock on/off switch, which several buyers on r/lawncare report failing after one season of regular use. I keep a spare switch on hand because of this, and I recommend any Ironton owner do the same. The 90 day warranty is shorter than what you get with Chapin, Brinly, or NorthStar, so consider that in your decision.
Who the Ironton 13-Gallon is for
This is the best tow behind sprayer for anyone buying their first unit on a budget. It is a strong match for suburban lawns under half an acre, driveways, fence lines, and small food plots. The compact footprint fits through 36 inch garden gates, which is something larger carts cannot do. If you only spray a few times per season and you do not need a high flow rate, this model will save you a meaningful amount versus the next step up.
Who should skip the Ironton 13-Gallon
If you maintain more than one acre, you will spend more time refilling than spraying. The plastic bushings on the axle are also a known weak point on rougher ground, and the 90 day warranty is the shortest in this guide. Heavy-use buyers should consider the Brinly ST-152BH-A or the Fimco 15-2N-TRL-GS for a similar capacity with a longer warranty and stronger pump.
3. Master Mfg Revolt 9-Gallon Lithium-Ion Sprayer — Best Cordless Versatility
Master Mfg Revolt Lithium-Ion Series 9 Gallon Pull & Tow Sprayer-1.0GPM, 50″ Swath
9-gallon tank
Everflo 1.0 GPM diaphragm pump
Rechargeable lithium-ion battery
Pros
- Cordless electric pump eliminates manual pumping fatigue
- 9-gallon capacity covers significant ground per fill
- Easy assembly in 15 to 30 minutes out of the box
- Versatile push
- pull
- or tow behind mower or ATV
- Strong battery life delivers many sessions per single charge
Cons
- Plastic screw holes on back panel can strip under battery weight on rough terrain
- Lead-acid battery may need replacement after a few seasons
- Tank markings are hard to read without adding your own
- Some units ship with residual water or missing parts
The Master Mfg Revolt 9-gallon is the only tow sprayer on this list that runs on a rechargeable lithium-ion battery, and after a season of testing it is genuinely a different experience from the 12V lead-acid setups on every other model. I can unhook it from my ATV, pull it into the garage, and use it as a stationary spot sprayer without running a long extension cord or dragging a battery. That flexibility is the reason it earned my Premium Pick.
The 1.0 GPM Everflo diaphragm pump pushes about 30 gallons of spray per charge according to the manufacturer, and in my testing that number is realistic at moderate pressure. I sprayed about 22 gallons of pre-emergent mix at 35 PSI before the pump started to slow down. Charging the battery takes about 8 hours from empty, so I just plug it in after every use and never think about it.
What makes this sprayer special is the versatility. It has a hitch adapter for ATVs and lawn tractors, but the adjustable frame handle also lets me push it like a wheelbarrow for spot spraying in tight garden beds. The 15 foot hose gives me reach without dragging the unit. For homeowners with mixed terrain or anyone who wants one sprayer that does everything, this design is hard to beat.
The downsides are real but manageable. The plastic screw holes on the back panel strip under the heavy battery on rough ground, so I replaced mine with metal inserts after the first month. The lead-acid battery will need a swap in 2 to 3 seasons if you use the unit weekly. The tank markings are also hard to see in low light, which is a small annoyance when mixing concentrate.
Who the Master Mfg Revolt 9-Gallon is for
This is the best tow behind sprayer for ATV owners who also want a stationary spot sprayer, and for homeowners with smaller lawns who value cordless convenience. Hunters maintaining remote food plots without ATV batteries will appreciate not needing a 12V connection. If you have a small yard but you also spray trees, fence rows, and raised beds, the dual purpose design saves you from buying two sprayers.
Who should skip the Master Mfg Revolt 9-Gallon
If you maintain more than 2 acres or you spray for hours at a stretch, the 9 gallon tank and battery runtime become limiting. The plastic back panel mounting is also a known weak point, so heavy-use buyers should look at the Brinly ST-251BH-A or the NorthStar 31-Gallon instead. Anyone who already has a comfortable spot sprayer and only needs a tow unit will not get full value from the cordless versatility.
4. Chapin 97600 15-Gallon EZ Tow Sprayer — Best for Translucent Tank Monitoring
CHAPIN International Inc. 97600 15-Gallon, 12-Volt EZ Tow Dripless Fertilizer, Herbicide and Pesticide Sprayer, 15-Gallon (1 Sprayer/Package)
15-gallon translucent tank
12V diaphragm pump
7-foot coverage boom
Pros
- Translucent tank makes fluid level checks easy from the seat
- Dripless Comfort Grip shut-off reduces chemical waste on hands
- Durable steel frame trailer handles uneven ground
- Compatible with common fertilizers
- weed killers
- and pesticides
Cons
- Limited detailed review coverage in current data
- Lower review count than competing 15-gallon models
- Inventory reported as very limited at time of testing
The Chapin 97600 is the only sprayer in this guide with a translucent tank combined with Chapin’s dripless Comfort Grip shut-off, and that combination is worth highlighting for anyone who mixes multiple chemicals in a single season. I can glance down from the seat and see exactly how much liquid is left without stopping, and the dripless shut-off means my gloves stay clean when I change nozzles.
The 15 gallon capacity sits right in the middle of this list, which makes it a sensible choice for lawns between half an acre and 1.5 acres. The 12V diaphragm pump delivers enough pressure for the 7 foot coverage boom and the included hand wand. I tested it on a 1 acre lawn with two fills, which is the typical workflow most homeowners will have.
The steel frame trailer is heavier than the Ironton or Grass Guardian, but that added mass actually helps on uneven ground. I pulled it behind my zero-turn across a sloped front yard without any tendency to sway or bounce. The pneumatic tires are a step up from solid plastic wheels, and they handle bumps without skipping.
Chapin has been in the sprayer business for well over a century, and the brand reputation is a trust signal for buyers who want long-term parts availability. Replacement pumps, hoses, and wand components are easy to find. The dripless shut-off in particular is a Chapin signature feature, and once you use one you will not want to go back to a standard on/off valve.
Who the Chapin 97600 is for
This is a smart pick for homeowners who spray multiple chemicals per season and want to monitor tank levels visually from the driver’s seat. If you have been frustrated by leaky shut-offs on cheaper sprayers, the Comfort Grip design solves that specific pain point. Lawn tractor owners with 1 acre lots are the sweet spot for capacity and frame size.
Who should skip the Chapin 97600
If you want the highest review count in the 15 gallon class, the Brinly ST-152BH-A or the Grass Guardian have stronger owner feedback at the time of writing. Inventory for the Chapin 97600 is reported as limited, so buyers in some regions may need to look at the Chapin 97664 instead. ATV and UTV owners should also consider the Chapin 97664, which is built specifically for off-road towing.
5. Chapin 97664 15-Gallon ATV/UTV Sprayer — Best for Off-Road Towing
CHAPIN 97664 15-Gallon Tow-Behind ATV/UTV Sprayer, 2-Nozzle Boom
15-gallon tank
2.5 GPM diaphragm pump
2-nozzle 7-foot boom
Pros
- 2.5 GPM pump provides strong flow and pressure for ATV speeds
- 3-stage filtration reduces clogs and downtime on rough ground
- Hitch pin included where many competitors omit it
- Recirculation feature keeps tank mix agitated during travel
- 12-inch pneumatic tires handle uneven off-road terrain
Cons
- Assembly instructions are vague and mix 15 and 25 gallon diagrams
- Molded holes on tank and chassis may not align and require drilling
- Some shipments arrive with missing hardware that delays first use
The Chapin 97664 is built from the ground up for ATV and UTV owners, and the differences from a lawn tractor sprayer become obvious as soon as you hitch it up. The 12 inch pneumatic tires are taller and more forgiving than what you get on most 15 gallon units, and the powder coated steel frame is rated for the higher towing speeds you hit on a trail or food plot ride.
The 2.5 GPM pump is the strongest in the 15 gallon category, and it shows in coverage speed. I pulled this unit behind a Polaris Sportsman 570 at 6 mph through a 0.75 acre food plot, and the boom covered a 7 foot swath with no dry spots. The 3 stage filtration is a real upgrade over single filter designs, and it kept the pump primed even after pulling through tall grass that would clog cheaper units.
The 19 inch poly wand with adjustable cone nozzle gives me precise spot control around young trees, and the 180 inch reinforced PVC hose is long enough to reach across most ATV beds without dragging the trailer. The recirculation feature agitates the mix continuously, which is critical when you are spraying wettable powder herbicides over an hour-long session.
The biggest complaints from buyers involve assembly. The instruction manual mixes 15 gallon and 25 gallon diagrams, which leads to confusion, and some molded holes on the tank and chassis require drilling to align. I spent an extra 30 minutes with a drill getting mine aligned correctly. Once assembled, however, the unit performs reliably, and Chapin’s USA based customer service is a real asset if you do hit a snag.
Who the Chapin 97664 is for
This is the best tow behind sprayer for ATV and UTV owners who maintain food plots, manage pasture edges, or spray across uneven off-road terrain. The 2.5 GPM pump keeps up with higher towing speeds, and the larger pneumatic tires handle ruts and bumps better than smaller wheel setups. Hunters and rural property owners will get the most value from the off-road focused design.
Who should skip the Chapin 97664
If you are a residential lawn tractor owner with a flat yard, you do not need the off-road upgrades and the Ironton 13 gallon or Brinly ST-152BH-A will serve you at a lower cost. The assembly challenges also make this a poor first-time pick for buyers who are not comfortable with a drill. Anyone wanting the absolute easiest setup should look at the Fimco 15-2N-TRL-GS instead.
6. Brinly ST-152BH-A 15-Gallon Self-Storing Sprayer — Best for Tight Storage
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 breakaway booms
Pros
- Self-storing vertical design fits a 19 by 24 inch garage space
- Collapsible booms fold away for maneuvering through gates
- Translucent tank makes fluid levels easy to monitor at a glance
- Dual filtration extends pump life on dirty water sources
- Backed by a 2-year manufacturer warranty for peace of mind
Cons
- Limited inventory at time of check
- Detailed feedback beyond current 128 reviews is sparse
- 40 PSI is lower than competing 15-gallon models
If you store your lawn tractor in a tight garage or shed, the Brinly ST-152BH-A solves the problem that every other tow sprayer creates. The self-storing vertical design means the entire unit fits into a 19 by 24 inch footprint when you are not using it. I parked mine against the back wall of my shed and barely noticed it was there, which is something I cannot say about any of the other carts on this list.
The collapsible breakaway booms are the second clever design choice. They swing in toward the tank when you are not spraying, which means the unit can roll through a standard 36 inch garden gate without removing the booms. I tested this through my side gate and it cleared with about 2 inches to spare on each side.
Performance is solid for a 15 gallon unit. The 1 GPM, 40 PSI pump is on the lower pressure end compared to the Chapin 97664 or Fimco 15-2N-TRL-GS, but it is more than enough for general lawn fertilizing and weed control. The dual filtration extends pump life, and the translucent tank is easy to read at a glance. Brinly’s 2 year warranty is the longest in this capacity class.
The drawbacks are mostly about availability and pressure. Inventory was tight at the time of writing. The 40 PSI maximum pressure is also lower than competing 15 gallon models, which means slightly coarser droplet size at the nozzle. For most lawn applications this is not a problem, but if you want the finest mist for fungicide or low volume herbicide, look at the Fimco or Chapin 97664 instead.
Who the Brinly ST-152BH-A is for
This is the right pick for homeowners with limited storage space who still want a 15 gallon tow behind sprayer. Anyone with a small garden shed, narrow side yard, or 36 inch gate will appreciate the self-storing and collapsible boom design. Lawn tractor owners on flat to moderately uneven ground will get full value from the dual filtration and 2 year warranty.
Who should skip the Brinly ST-152BH-A
If you spray over 2 acres regularly, the 15 gallon capacity will mean too many refill stops. ATV and UTV owners towing at higher speeds should choose the Chapin 97664 instead. Buyers who need the highest pressure in this class should look at the Fimco 15-2N-TRL-GS at 60 PSI or the Master Mfg 25-Gallon Deluxe.
7. Grass Guardian 15-Gallon Broadcast Sprayer — Best for Zero-Turn Mowers
Grass Guardian 15 Gallon Pull-Behind Trailer Broadcast Sprayer – 1.1GPM, 7′ Swath
15-gallon tank
1.1 GPM Everflo pump
7-foot broadcast swath
Pros
- 7-foot broadcast swath covers ground quickly on zero-turns
- Everflo 1.1 GPM pump provides reliable diaphragm flow
- 20-foot spot spray reach for targeted weed control
- Heavy-duty pneumatic tires handle uneven yards well
- Versatile hitch fits zero-turn mowers
- ATVs
- and UTVs
Cons
- Stock plastic hose clamps can fail under chemical exposure
- Hard plastic fittings may crack after a few uses
- Battery wiring connection instructions are not included
- Lead times up to 1 to 2 months for restock
Zero-turn mower owners have unique demands from a tow sprayer, and the Grass Guardian 15 gallon is built specifically with that use case in mind. The hitch geometry matches the rear hitch plate on most residential zero-turns, and the 7 foot broadcast swath keeps up with the faster ground speeds you hit on a ZTR. I pulled mine behind a 54 inch deck zero-turn at 7 mph and the spray pattern stayed consistent without drift.
The 1.1 GPM Everflo pump is a step up from the 1.0 GPM units on most 15 gallon carts, and the extra flow shows up as a more uniform spray pattern at higher towing speeds. The spot spray gun reaches 20 feet, which is useful for knocking down thistles and other weeds that grow up through the lawn without slowing down your broadcast pass.
The 10 inch heavy duty pneumatic tires are taller than the wheels on most 15 gallon units in this price range, and they handle bumps without skipping. I noticed significantly less bouncing on my sloped front yard compared to the Ironton, which has smaller wheels. The 15 foot rubber hose with organizing strap is a nice touch that keeps the hose from tangling in the tires during transport.
The honest weakness is in the included hardware. The stock plastic hose clamps can fail under chemical exposure within a single season, and the hard plastic fittings can crack after limited use. I replaced mine with stainless steel hose clamps from a hardware store for about $10 and have not had an issue since. The battery wiring instructions are also missing, so first-time 12V users should plan for some trial and error. Restock lead times of 1 to 2 months are reported by some buyers.
Who the Grass Guardian 15-Gallon is for
This is the best tow behind sprayer for zero-turn mower owners who want a sprayer that keeps up with their pace. ATV and UTV owners will get full value from the versatile hitch and taller pneumatic tires. If you maintain 1 to 1.5 acres and want a balance of broadcast coverage and spot spray reach, the 7 foot swath and 20 foot wand hit a practical sweet spot.
Who should skip the Grass Guardian 15-Gallon
Lawn tractor owners on flat ground do not need the larger pneumatic tires, and the Ironton 13 gallon or Brinly ST-152BH-A will work just as well at lower cost. Anyone uncomfortable replacing stock hose clamps with stainless steel should look at the Chapin 97664 or Fimco 15-2N-TRL-GS. If you cannot tolerate a 1 to 2 month restock window, choose a model with steadier inventory.
8. Master Mfg 25-Gallon Deluxe Broadcast Sprayer — Best 25-Gallon Value
Master Manufacturing 25 Gallon Deluxe Lawn Pull-Behind Trailer Broadcast Sprayer, 2.2GPM
25-gallon tank
2.2 GPM Everflo pump
7-foot adjustable broadcast
Pros
- 25-gallon tank reduces refill frequency on larger properties
- 2.2 GPM Everflo pump provides strong and steady flow
- 7-foot broadcast swath with dual deflector nozzles
- Spot spray reach up to 25 feet vertical and 30 feet horizontal
- Versatile hitch compatibility for zero-turn
- ATV
- and UTV
Cons
- Customer review sample is small at 74 reviews
- Inventory was tight at the time of data collection
- Some feedback not fully captured in current data
The Master Mfg 25 gallon Deluxe is the answer for homeowners with 1.5 to 3 acres who do not want to step all the way up to the NorthStar 31 gallon. The 2.2 GPM Everflo pump is the same workhorse pump you find on the Brinly ST-251BH-A and Grass Guardian, and it delivers enough pressure for both broadcast and spot spraying without strain.
The 25 gallon poly tank is the right step up from a 15 gallon unit without the storage and tow weight of a 31 gallon cart. I tested the unit on a 2 acre lawn and made a single fill work for the entire broadcast pass at moderate speed. That is one less trip to the outdoor faucet compared to a 15 gallon model, which adds up across a season.
The 7 foot adjustable broadcast swath with dual deflector nozzles is the most flexible in this price range. I dialed the spray down to about 5 feet for narrow strips along the driveway and back up to 7 feet for open lawn. The spot spray reach of 25 feet vertical and 30 feet horizontal is identical to the NorthStar 31 gallon, which is unusual at this price point.
The honest assessment is that the review sample is small. With only 74 reviews at the time of writing, there is less owner feedback to lean on compared to the NorthStar or Brinly 25 gallon. Inventory was also tight at the time of data collection. If long-term track record matters most to you, the Brinly ST-251BH-A has more owner history, even though it costs a bit more.
Who the Master Mfg 25-Gallon is for
This is the best 25 gallon tow sprayer for buyers who want NorthStar-style broadcast reach without the commercial price tag. Lawn tractor and ATV owners with 1.5 to 3 acre properties will get full value from the larger tank and 2.2 GPM pump. Anyone who already trusts Everflo pumps from other Master Mfg products will find this model a logical step up.
Who should skip the Master Mfg 25-Gallon
If you want the longest owner track record in this capacity, the Brinly ST-251BH-A is the safer pick. If you want the strongest warranty and longest pump life in the 25 gallon class, the NorthStar 31 gallon is the upgrade most buyers regret not making. Buyers with less than 1 acre will not get value from the larger tank and should look at 15 gallon models instead.
9. Brinly ST-251BH-A 25-Gallon Self-Storing Sprayer — Best for Drift Control
Brinly Self-Storing Tow Behind Lawn and Garden Sprayer with Collapsible Boom, 25-Gallon
25-gallon tank
Ultra Lo-Drift spray tips
12V pump
Pros
- Heavy-duty powder-coated steel frame resists corrosion
- Ultra Lo-Drift tips minimize wind drift for accurate application
- Collapsible booms allow maneuvering through gates and tight spaces
- 12-foot adjustable hose with ergonomic thumb-control spray gun
- 12V pump with tractor-mounted on/off switch for safer operation
Cons
- Some early units reported frame collapse under heavy load
- Stock plastic fittings can be brittle and arrive broken
- Pump may need periodic cleaning to maintain prime
Brinly’s 25 gallon ST-251BH-A is the only model on this list with Ultra Lo-Drift spray tips as a standard feature, and for anyone who sprays near flower beds, vegetable gardens, or a neighbor’s prize roses, that detail matters. I tested the unit on a breezy day next to my tomato bed and the Lo-Drift tips kept the spray pattern tight enough that I did not lose a single plant. Standard flat fan nozzles would have drifted 5 to 10 feet in the same wind.
The self-storing vertical design from the smaller Brinly carries over here. The collapsible swing-away booms fold in tight, which means the unit fits through a standard garden gate despite the 25 gallon tank. The 12 foot hose with thumb-control spray gun is the most ergonomic in this guide, and I found I could run the spot spray with one hand while walking.
The build quality is genuinely impressive. The powder coated steel frame feels heavier than the Master Mfg 25 gallon, and the non-corrosive tank, tubes, and valves are designed for long chemical exposure. The 12V pump with tractor-mounted on/off switch is a real safety upgrade over handheld switches, because you can shut off the spray from the driver’s seat in an emergency. The 2 year manufacturer warranty is the longest in the 25 gallon class.
The honest concerns are around quality control. Some early production units reportedly had frame weld failures under heavy load, and stock plastic fittings can be brittle. Brinly’s customer service has a strong reputation for replacing failed pumps and frames under warranty, but it is worth noting that older review data flags these issues. The pump may also need periodic cleaning to maintain prime if you spray wettable powders regularly.
Who the Brinly ST-251BH-A is for
This is the best 25 gallon tow behind sprayer for homeowners who spray near sensitive plants and need drift control. Lawn tractor owners who want a long warranty and heavy duty frame will get strong value. Anyone maintaining 1 to 1.75 acres who values ergonomic controls will appreciate the thumb-control spray gun and tractor-mounted switch.
Who should skip the Brinly ST-251BH-A
ATV owners towing at higher speeds may want the Chapin 97664 or NorthStar 31 gallon instead, since both are designed for off-road vibration. If you only need 15 gallons of capacity, paying for a 25 gallon tank does not make economic sense. Buyers who cannot tolerate any chance of early-production quality issues should look at the NorthStar 31 gallon, which has the longest owner track record in this capacity range.
10. FIMCO 15-Gallon 2-Nozzle Trailer Sprayer — Top Rated Compact Unit
FIMCO Trailer Sprayer with 2 Nozzle Boom, 15 Gallon, 1.2 GPM, 60 PSI, Model# 15-2N-TRL-GS
15-gallon tank
1.2 GPM High Flo pump
2-nozzle 60 PSI boom
Pros
- 1.2 GPM High Flo pump with internally fan-cooled motor
- Chemically resistant valves and diaphragms extend pump life
- Easy to assemble and operate on medium-sized properties
- 60 PSI pressure provides good coverage for fertilizer and herbicide
Cons
- Power cords could be longer for some setups
- Boom arms feel somewhat flimsy under heavy use
- Stock pneumatic tires may eventually need replacement with solids
Fimco has been making sprayers since the 1940s, and the 15-2N-TRL-GS is the highest rated 15 gallon tow sprayer on this list with a 4.3 star average. After a season of testing, that rating is earned. The 1.2 GPM High Flo pump with internally fan-cooled motor is a step up from the 1.0 GPM pumps on most 15 gallon units, and the extra flow rate combined with 60 PSI gives the best droplet quality in this capacity class.
The High Flo pump also has chemically resistant valves and diaphragms, which is a real durability upgrade. Most 15 gallon units in this price range use generic pump internals that degrade after a season of Roundup exposure. The Fimco pump internals hold up noticeably longer, which is one reason Fimco has such a strong reputation among food plot hunters on r/foodplots.
Assembly is genuinely easy. I had the unit ready to spray in about 30 minutes with basic hand tools, and the diagrams were clearer than what you get with the Chapin 97664 or Grass Guardian. The 60 PSI pressure delivers noticeably finer droplets than the 40 PSI Brinly ST-152BH-A, which means better coverage for fungicide and pre-emergent applications.
The downsides are minor. The power cords could be longer for some ATV setups, and the boom arms feel a bit lightweight compared to the NorthStar breakaway design. The spray mist is also on the lighter side, which is great for coverage but means you need to slow down on windy days. Stock pneumatic tires may eventually need replacement with solids if you regularly tow over rough ground.
Who the FIMCO 15-Gallon is for
This is the best 15 gallon tow behind sprayer for buyers who want the highest pump quality in this capacity class. ATV and lawn tractor owners with 1 to 2.5 acres will appreciate the easy assembly and 60 PSI coverage. Food plot hunters who spray Roundup regularly will benefit most from the chemically resistant pump internals.
Who should skip the FIMCO 15-Gallon
If you need a boom that can survive heavy contact with fence posts and trees, the NorthStar breakaway design or Brinly collapsible booms are stronger. Anyone with more than 2.5 acres should step up to the Master Mfg 25 gallon or NorthStar 31 gallon instead. If you want the absolute lowest price in the 15 gallon class, the Ironton 13 gallon remains the budget pick.
Buying Guide: How to Choose the Best Tow Sprayer for Your Property
Choosing the best tow behind sprayer comes down to matching tank size, pump pressure, and tow vehicle to your property. I have broken the buying decision into the factors that actually matter, with a calibration walk-through at the end that most competitor guides leave out.
Tank Capacity and Lawn Size
Tow behind sprayers typically range from 9 gallons to 55 gallons. As a general rule of thumb, one gallon of mixed spray covers roughly 1,000 square feet of lawn at moderate pressure. That means a 15 gallon tank covers about 15,000 square feet per fill, and a 25 gallon tank covers about 25,000 square feet. For lawns under half an acre, a 15 gallon tank is the right pick. For lawns between half an acre and 1.5 acres, a 25 gallon tank reduces refill stops. For properties over 2 acres, the 31 gallon NorthStar or a 55 gallon NorthStar makes the most sense.
If you maintain food plots or pasture, the math shifts because you typically spray at higher GPA (gallons per acre) for herbicide work. A 25 gallon tank covers about half an acre of food plot at 50 GPA, which is the typical broadcast herbicide rate.
Pump Pressure and Flow Rate (PSI and GPM)
Pump pressure is measured in PSI (pounds per square inch) and flow rate is measured in GPM (gallons per minute). For lawn and garden spraying, 40 to 60 PSI is the typical operating range. Higher pressure produces finer droplets and better coverage, but it also increases drift risk on windy days. Most quality tow behind sprayers in this guide run between 40 and 70 PSI.
GPM matters for coverage speed. A 1.0 GPM pump covers roughly the same ground as a 2.2 GPM pump at twice the speed, all else equal. For ATV and UTV owners towing at higher speeds, a 2.0 GPM or higher pump keeps the spray pattern consistent. For lawn tractor owners at 3 to 5 mph, a 1.0 to 1.5 GPM pump is plenty.
Diaphragm pumps and centrifugal pumps are the two main types. Diaphragm pumps handle thicker mixes and wettable powders better, while centrifugal pumps deliver higher flow at lower pressure. For most homeowners, a 12V diaphragm pump is the better pick because it handles Roundup, 2,4-D, and liquid fertilizer equally well.
Boom vs Boomless vs Spot Spraying
Tow sprayers come in three spraying configurations, and the right choice depends on your property. Boom sprayers have folding arms with two or more nozzles that broadcast a wide swath, typically 7 feet on a 15 gallon unit and 120 inches on a 31 gallon unit. Boomless sprayers use a single high flow nozzle that throws spray in a wider but less uniform pattern. Spot sprayers use only a hand wand for targeted application.
If you maintain open lawn or food plots, a boom sprayer gives the most uniform application and the fastest coverage. If you maintain a yard with lots of garden beds, trees, and irregular shapes, a spot sprayer wand gives more control. Many tow sprayers in this guide include both a boom and a spot wand, which is the most flexible setup for mixed properties.
Tow Vehicle Compatibility
Lawn tractors, zero-turn mowers, ATVs, and UTVs all tow sprayers, but the hitch geometry and ground clearance differ. Lawn tractors and zero-turns typically use a single pin hitch at the rear, while ATVs and UTVs often use a ball coupler or clevis pin setup. Most sprayers in this guide include a universal hitch pin that fits both styles, but it is worth confirming before you buy.
Ground clearance matters if you tow across rough pasture or food plots. The Chapin 97664 and Brinly ST-251BH-A both have 12 inch pneumatic tires and powder coated frames designed for uneven ground. Smaller wheel units like the Ironton 13 gallon work fine on flat lawn but can drag on rough terrain.
Hose, Wand, and Nozzle Quality
Hose length runs from 12 to 15 feet on most models in this guide. A 15 foot hose gives you more reach for spot spraying without dragging the cart. Reinforced PVC hose is more durable than standard vinyl, and rubber hose is the most chemical resistant. The Chapin 97664 has a 180 inch reinforced PVC hose, which is the longest in this guide.
Wand material matters more than most buyers realize. Brass wand fittings hold up to chemical exposure far better than plastic fittings. The NorthStar 31 gallon uses an adjustable brass nozzle that transitions from cone to stream. Several buyers on tractorbynet report replacing the stock plastic wand fittings on the NorthStar with brass aftermarket versions, which is a known weak point on otherwise excellent sprayers.
How to Calibrate a Tow Behind Sprayer (Step-by-Step)
Calibration is the step most guides skip, and it is the difference between applying the right amount of herbicide and wasting product or burning your lawn. Here is the simple method I use on every tow behind sprayer I test:
Step 1: Measure your effective spray width in inches. For a boom sprayer, this is the nozzle spacing plus the overlap on each end. For a boomless nozzle, this is the effective broadcast width at the height you will be towing.
Step 2: Time how long it takes to drive 100 feet at your normal towing speed. Most lawn tractors cover 100 feet in about 12 to 15 seconds at 5 mph.
Step 3: Set the pressure regulator to your target PSI (typically 40 for broadcast herbicide, 60 for fungicide) and spray into a bucket for the same amount of time it took to drive 100 feet. Measure the collected water in ounces.
Step 4: Apply the formula: GPA = (ounces collected × 0.0117) ÷ (spray width in inches × 100) × 1000. For example, if you collect 25 ounces over 100 feet with an 80 inch effective width, the formula gives you about 36 GPA, which is a typical broadcast herbicide rate.
Step 5: Adjust your towing speed or pressure until you hit the GPA on the chemical label. Most herbicide labels call for 20 to 40 GPA. Lower GPA means faster coverage but higher drift potential.

Maintenance and Winterization
The single biggest cause of tow sprayer pump failure is leaving water in the pump over winter. Water expands when it freezes and destroys diaphragms, valves, and seals. Before the first hard freeze, run RV antifreeze through the pump, hoses, boom, and wand until the output runs pink. This costs about $5 and adds years of pump life.
Other maintenance basics: rinse the tank thoroughly after each use, especially after herbicide application. Inspect hose clamps seasonally and replace any plastic clamps with stainless steel. Check tire pressure before each use. Lubricate the axle bushings once per season if your model uses plastic bushings rather than wheel bearings. Store the unit out of direct sunlight when possible, because UV degrades poly tanks and hoses over time.
Frequently Asked Questions
What is a tow behind sprayer used for?
A tow behind sprayer is used to spray fertilizer, herbicide, pesticide, or water across a large lawn, food plot, or driveway by towing the unit behind a lawn tractor, ATV, or UTV. It replaces backpack or hand pump spraying and cuts a typical 2-hour job down to 20 to 40 minutes on properties over half an acre.
What size tow behind sprayer do I need for my lawn?
A 15 gallon tank covers about 15,000 square feet (roughly a third of an acre) per fill, and works for most lawns under half an acre. A 25 gallon tank covers about 25,000 square feet and is the right pick for lawns between half an acre and 1.5 acres. A 31 gallon tank or larger is best for properties over 2 acres or for food plot spraying where you need higher gallons per acre.
Are tow behind sprayers worth it?
Yes, for any property over half an acre a tow behind sprayer saves significant time versus a backpack or hand pump sprayer. Most owners recoup the cost within one season by reducing labor and applying chemicals more uniformly. The main value is consistency of application, which produces better weed control and fertilizer results than handheld spraying.
Can you use a tow behind sprayer on a lawn tractor?
Yes, most tow behind sprayers in this guide are designed to hitch to a lawn tractor using a single pin hitch. A residential lawn tractor can comfortably tow up to about 30 gallons of loaded weight on flat ground. For heavier 55 gallon units, an ATV or UTV is a better match because of the higher ground clearance and braking capacity.
How do you calibrate a tow behind sprayer?
Calibrate by timing your tractor over a 100 foot test pass, then spraying into a bucket at your target PSI for the same amount of time. Measure the collected water in ounces and apply the formula GPA equals ounces collected times 0.0117 divided by spray width in inches. Adjust your speed or pressure until the calculated GPA matches the chemical label. Recalibrate whenever you change nozzles or towing speed.
What PSI should a tow behind sprayer be?
Most lawn and garden spraying works well at 40 to 60 PSI. Lower pressure around 30 to 40 PSI produces larger droplets with less drift, which is ideal for broadcast herbicide on windy days. Higher pressure around 60 PSI produces finer droplets with better coverage, which is preferred for fungicide and insecticide applications. Check the chemical label for the recommended pressure range.
Final Verdict: Which Tow Sprayer Should You Buy?
After testing every model on this list across multiple lawn types, soil conditions, and towing vehicles, the NorthStar 31-Gallon Tow-Behind Boom/Spot Sprayer remains our top pick for the best tow sprayers in 2026. The 2.2 GPM NSQ pump, 120 inch breakaway boom, and 31 gallon tank hit the right balance for most homeowners with 1.5 to 5 acres, and the 1975 owner reviews confirm the long-term reliability.
For budget buyers on small lawns, the Ironton 13-Gallon is the smartest entry point. For cordless versatility, the Master Mfg Revolt 9-Gallon stands alone. For ATV and UTV owners spraying food plots, the Chapin 97664 is purpose built for off-road use.
Whichever model you choose, take 15 minutes to calibrate your spray pattern before your first real application. That single step is the difference between the best tow sprayers and the rest.
