8 Best Tow Behind Sprayers for Your Riding Mower or ATV

There comes a point on every small farm when a backpack sprayer just doesn’t cut it anymore. That moment you realize you’ve spent an hour spraying just one pasture fence line, and you still have the back forty to go. A tow-behind sprayer, hitched to your riding mower or ATV, is the single biggest upgrade you can make for managing weeds, pests, and soil health across several acres.

Choosing the Right Sprayer for Your Property

Picking the right tow-behind sprayer isn’t about finding the one with the biggest tank or the highest pressure; it’s about matching the tool to your land and your tasks. The first thing to consider is the relationship between tank size and your acreage. For one or two acres of lawn or pasture, a 15-gallon tank is often plenty, but if you’re managing three to five acres, a 25-gallon model will save you from constantly stopping to mix another batch and refill.

Next, consider your vehicle and terrain. A standard riding mower is perfect for pulling a sprayer across relatively flat lawns and smooth pastures, but it will struggle on steep grades or rough, uneven ground. If your property includes wooded trails, rocky patches, or hills, an ATV is the far better choice, as it offers the power, traction, and stability needed to safely haul a full tank of liquid. A heavier sprayer full of water can easily push a light mower around on a downhill slope, so don’t underestimate the importance of this match-up.

Finally, think about how you’ll be spraying. Most models come with both a broadcast boom and a handheld spray wand, but they aren’t all created equal. A boom with multiple nozzles is essential for efficiently covering large, open areas like a field or lawn. A wand, on the other hand, is your tool for precision work—spot-treating invasive thistle, spraying herbicides along a fence you can’t get the mower next to, or applying fungicide to specific fruit trees. Look for a long hose on the wand (15 feet is a good minimum) to give you the reach you need without constantly repositioning your vehicle.

Agri-Fab 45-0292: A Solid All-Around Choice

The Agri-Fab 15-gallon sprayer is the definition of a reliable workhorse for the small-scale property owner. It’s not flashy, but it does exactly what you need it to do without fuss. With its 15-gallon tank, it’s perfectly sized for properties in the one-to-two-acre range, allowing you to cover a good amount of ground before needing a refill. The 12-volt pump provides adequate pressure for both the 80-inch spray boom and the handheld wand, making it versatile enough for both broadcast and spot spraying.

What makes the Agri-Fab a smart choice is its straightforward, dependable design. The large screw cap makes filling and mixing easy, and the tank is easy to flush and clean—a critical step for sprayer longevity and preventing chemical cross-contamination. It hooks up to any standard riding mower or ATV hitch with zero drama, and its large wheels handle typical lawn and pasture terrain well. It’s a simple, effective tool built for the most common spraying tasks.

If you need a sprayer for general lawn care, liquid fertilizer application, or managing common pasture weeds on a couple of acres, this is your unit. It’s an affordable, no-nonsense machine that gets the job done. For those with vast acreage or a need for very high pressure to tackle dense brush, you might look elsewhere, but for the typical hobby farm, the Agri-Fab 45-0292 is a fantastic starting point.

NorthStar 21-Gallon Sprayer: For Tough Jobs

When your spraying needs go beyond simple lawn fertilizer, the NorthStar lineup deserves a serious look. This 21-gallon model is built for more demanding applications, featuring a commercial-grade NorthStar NSQ Series pump that delivers higher pressure and stands up to aggressive chemicals that can wear out lesser pumps. This makes it ideal for applying herbicides, pesticides, and other treatments that require consistent, powerful performance.

The sprayer’s durability is a key selling point. The tank is made from a thick, chemical-resistant polymer designed to withstand years of sun and use, and the components are engineered for longevity. This isn’t a use-it-for-a-season-and-replace-it tool; it’s an investment. The extra gallon capacity over a standard 20-gallon model might not seem like much, but it can mean the difference between finishing a job and having to mix one last small batch.

This is the sprayer for the hobby farmer who is serious about pest and weed management. If you’re dealing with stubborn brush, need to ensure deep foliage penetration on dense plants, or simply want a piece of equipment that you know will fire up and work hard every time, the NorthStar is built for you. It’s overkill for a simple suburban lawn, but it’s right at home in a large garden, an orchard, or a multi-acre pasture.

John Deere LP19478: Reliable Brand Performance

For those who already operate a John Deere mower or utility vehicle, this 15-gallon sprayer offers the seamless integration and trusted performance the brand is known for. It’s engineered to work perfectly with John Deere equipment, from the wiring harness to the hitch pin. This isn’t just about a matching green color; it’s about the peace of mind that comes from a system designed to work together without modification or hassle.

The LP19478 features a dual-nozzle boom that provides a solid 80-inch spray width, ideal for efficient lawn coverage. The pump delivers a steady 60 PSI, which is the sweet spot for most herbicides and liquid fertilizers, ensuring good coverage without excessive drift. The included handgun has an adjustable nozzle, allowing you to switch from a fine mist to a solid stream, which is incredibly useful for reaching distant targets or hitting stubborn weeds at the base.

If you value reliability and the proven ecosystem of a major brand, the John Deere sprayer is a confident choice. It may come at a slight premium compared to other brands with similar specs, but you’re paying for the robust build quality, parts availability, and the certainty that it will perform as expected. This is the right sprayer for the John Deere owner who wants a dependable, no-surprises tool for maintaining a pristine property.

Fimco 25-Gallon Sprayer: For Larger Acreage

Fimco is a name that’s been in the sprayer game for a long time, and their 25-gallon tow-behind model is a testament to that experience. This sprayer is built for efficiency on larger properties, typically in the two-to-five-acre range. That 25-gallon capacity is the standout feature, drastically reducing the number of stops for refilling and remixing, which is one of the biggest time sinks when spraying a large area.

This model often comes equipped with a 5-nozzle boom, providing a wide and consistent 10-foot spray swath. This is a significant step up from the 7-foot booms on smaller models and translates directly into fewer passes to cover your field or lawn. Paired with a reliable 12-volt, 2.1 GPM pump, it provides the volume needed to feed that wide boom effectively. The handgun and its 15-foot hose remain ready for any spot treatments you encounter along the way.

The Fimco 25-gallon sprayer is for the person whose main bottleneck is time. If you find yourself frustrated by how long it takes to spray your property and spend more time at the spigot than on your mower, this is the upgrade you need. It’s a practical, large-capacity machine designed to help you cover more ground, faster.

Brinly-Hardy ST-25BH: Built for Durability

The Brinly-Hardy 25-gallon sprayer immediately stands out with its heavy-duty, powder-coated steel frame. This isn’t a sprayer that feels flimsy; it’s built to be knocked around. For those of us whose properties include bumpy pastures, wooded trails, and the occasional unseen tree root, that robust construction provides a lot of confidence. The large pneumatic tires also contribute to a smoother ride, reducing bouncing and jostling that can put stress on the tank and boom.

Beyond its tough exterior, the ST-25BH is a highly functional unit. The 25-gallon tank is ideal for larger properties, and the collapsible boom design is a smart feature. This allows for easy transport through gates and tight spaces without risking damage to the nozzles, and it makes for more compact storage in the shed or barn. The easy-to-access drain plug and filter system also simplify the all-important cleanup process.

This is the sprayer for the farmer who is hard on their equipment. If you value longevity and know that your tools will be put through their paces over varied terrain, the Brinly-Hardy’s durable build is a major asset. It’s a practical, tough-as-nails machine that prioritizes a long service life.

Chapin 97900: No-Premix Convenience System

The Chapin 97900 15-gallon sprayer introduces a feature that can be a genuine game-changer: a no-premix, mix-on-demand system. Instead of mixing your chemical concentrate into the main 15-gallon tank with water, you fill the main tank with plain water and put your concentrate into a separate, smaller 2-gallon tank. A switch then allows you to spray just water, or to have the system automatically mix the concentrate with the water at a set ratio as you spray.

This system offers two huge advantages. First, it eliminates waste. If you don’t use the whole tank, you’re left with only water, not an expensive chemical mix that you have to figure out how to use or dispose of. Second, it makes cleanup a breeze. You only need to rinse the small concentrate tank and the lines, not the entire 15-gallon main tank. This is a massive time-saver and is much safer when switching between different types of chemicals, like an herbicide and a fertilizer.

If you value precision, hate wasting expensive chemicals, and want the absolute easiest cleanup possible, the Chapin 97900 is made for you. It’s an innovative solution for the hobby farmer who might be spraying different sections of their property with different solutions on the same day. The convenience factor is simply unmatched.

Master MFG Spot Sprayer: For Targeted Use

While most tow-behind units try to be a jack-of-all-trades, the Master MFG Spot Sprayer is a specialist. This type of sprayer typically forgoes the large broadcast boom entirely, focusing all its capability on the spray wand. With a powerful pump and an extra-long hose (often 20 feet or more), its entire purpose is to give you unparalleled reach and precision for spot treatments.

This design makes it the perfect tool for tasks where a boom is useless or even counterproductive. Think of spraying invasive weeds along a creek bed, treating poison ivy climbing up trees deep in a woodlot, or applying pesticide to the base of fruit trees in an orchard. The high-quality, adjustable spray gun allows you to go from a wide cone for covering a patch of weeds to a long-distance stream to reach the top of a small tree.

Do not buy this sprayer if your primary need is to cover a two-acre lawn. But if your biggest challenges are fence lines, ditches, building perimeters, and other hard-to-reach areas, this is the most effective tool for the job. It’s for the farmer who needs a scalpel, not an axe, for their weed and pest management.

Precision TCT25: Versatile Boom and Wand

The Precision TCT25 sprayer is designed around the idea of versatility. It combines a respectable 25-gallon tank with a boom and wand system that offers excellent flexibility for properties with mixed needs. The 7-nozzle boom provides a very wide 12-foot spray pattern, making quick work of large, open pastures or lawns. This is a significant coverage advantage that reduces the number of passes needed.

What sets it apart is the thoughtful design of its components. The spray wand often comes with a high-quality brass nozzle, which is more durable and provides a more consistent pattern than cheaper plastic alternatives. The sprayer’s layout also provides easy access to the pump and drain valve, which simplifies maintenance and cleaning. It’s a unit that feels like it was designed by people who actually use sprayers.

This is the ideal sprayer for the hobby farmer with a little bit of everything: a couple of acres of pasture, a sizable lawn, a long gravel driveway with weeds, and an orchard that needs spot treatment. The wide boom handles the big areas efficiently, while the quality wand is ready for all the detailed work. If you need one machine that can adapt to many different jobs without compromise, the Precision TCT25 is a top contender.

Key Features: Pump, Tank Size, and Nozzles

When you cut through the brand names and marketing, a sprayer’s performance boils down to three core components: the pump, the tank, and the nozzles. The pump is the heart of the system, creating the pressure that delivers the spray. You’ll see specs like GPM (gallons per minute) and PSI (pounds per square inch). GPM determines how much liquid the pump can move, which is critical for supplying a wide, multi-nozzle boom. PSI determines the force of the spray, affecting droplet size and the wand’s reach. A pump that can deliver 2.0+ GPM and 60 PSI is a strong benchmark for versatile performance.

Tank size, as we’ve discussed, is all about workflow and efficiency. A polyethylene tank is the industry standard and is durable enough for farm use. Key features to look for are a large, easily accessible fill cap and a drain plug located at the tank’s lowest point. This makes it incredibly easy to empty and rinse the tank completely, which is vital for preventing chemical buildup and ensuring the pump’s longevity.

Finally, the nozzles are where the liquid meets the world. They shape the spray pattern and determine the droplet size. Most booms use flat-fan nozzles, which create an overlapping pattern for even broadcast coverage. Wands should have adjustable nozzles that can switch from a cone to a stream. Having high-quality, non-clogging nozzles, and even better, a system with interchangeable tips for different applications, can elevate a good sprayer to a great one. Don’t overlook these small but critical components.

Choosing a tow-behind sprayer is about investing in your own efficiency, freeing up valuable time to spend on other farm projects. By matching the tank size, power source, and spray style to your specific property, you get a tool that works for you, not against you. The right sprayer transforms a day-long chore into a simple morning task.
