When you have a lot of ground to cover, the NorthStar 31-Gallon model is a game changer. The sheer volume allows for long, uninterrupted work sessions.
This sprayer is designed for those who prioritize efficiency and want to minimize trips back to the water source.
The spring-loaded breakaway boom is a fantastic feature, preventing damage if you accidentally clip a tree or garden border while turning.
Because of its larger footprint and higher weight when full, it requires a tractor with sufficient towing capacity to handle the load safely.

What to Look for in Best Tow Behind Lawn Sprayer
Choosing Correct Tank Capacity
When selecting your sprayer, matching the tank size to your lawn dimensions is the most critical step for efficiency. For smaller residential lots under a half-acre, a 15-gallon tank is usually sufficient and prevents excessive weight on your mower. However, if you manage a sprawling estate or large acreage, opting for a 25 to 31-gallon capacity is vital to minimize frequent refill stops. Always consider the total weight of the liquid, as water weighs approximately 8.3 pounds per gallon; ensure your garden tractor or ATV has the towing capacity to handle a full tank safely on uneven terrain.
Pump Pressure and Performance
The heart of your tow-behind sprayer is the 12-volt pump, which dictates the consistency of your chemical application. Look for models featuring high-quality diaphragm pumps that provide steady PSI, typically ranging from 40 to 70 PSI, to ensure even coverage across your lawn. A consistent flow rate prevents patchy weed control or fertilizer burns. Many top-rated units include adjustable pressure regulators, allowing you to switch between low-pressure spot spraying for delicate flowers and high-pressure broadcast spraying for broadleaf weeds. Prioritize pumps with thermal overload protection to prevent motor burnout during long sessions in the hot summer sun.
Boom Width and Coverage
The spray boom width determines how quickly you can cover your property, but it must also be compatible with your lawn's layout. A wider boom, such as a 60-inch or 80-inch span, is excellent for open, flat areas where you want to maximize your time. If your yard contains many trees, garden beds, or narrow paths, a narrower boom or one with foldable wings is far more practical. Ensure the nozzles provide a uniform spray pattern to avoid skips or overlaps, which can lead to unsightly, uneven growth patterns that ruin the aesthetic appeal of your turf.
Material Durability and Build
Since these sprayers are exposed to harsh chemicals and outdoor elements, build quality is non-negotiable for long-term ownership. Seek tanks constructed from UV-resistant, high-density polyethylene, as these resist cracking and degradation from prolonged sun exposure. The frame should be powder-coated steel to prevent rust and corrosion, especially since you will be working with fertilizers and herbicides that can accelerate metallic decay. Check that all hose connections are reinforced and use stainless steel clamps rather than plastic, as these provide a leak-proof seal that protects your equipment and prevents chemical spills from damaging your lawn or garden soil.
Compatibility and Hitch Setup
Before finalizing your purchase, verify that the sprayer's hitch system is compatible with your specific lawn tractor, zero-turn mower, or ATV. Most tow-behind sprayers use a universal pin-style hitch, but some require specific mounting brackets to ensure stability during turns. It is also crucial to check the electrical connection; most units require a 12-volt battery hookup. Ensure your mower has an accessible battery or an auxiliary power port. A secure hitch connection is paramount when navigating slopes or bumpy ground, as a loose connection can cause the sprayer to tip or disconnect, potentially causing significant equipment damage.
Spot Sprayer Versatility
Beyond broadcast coverage, the ability to switch to a handheld wand is a game-changer for detailed lawn care. A high-quality spot sprayer wand allows you to target specific weeds, fence lines, or ornamental shrubs without treating the entire lawn. Ensure the included hose is at least 15 to 20 feet long, providing enough reach to walk around your mower comfortably. Look for adjustable spray tips on the wand that can transition from a fine mist for foliage to a concentrated stream for distant targets, giving you professional control over every corner of your property while maintaining your primary broadcast setup.
Maintenance and Winterization
Proper maintenance is the secret to a long-lasting sprayer. After every use, flush the tank and lines with clean water to remove chemical residues that can clog nozzles or degrade pump seals. At the end of the season, winterization is mandatory; run a non-toxic RV antifreeze through the pump and lines to prevent internal cracks caused by freezing temperatures. Regularly inspect the intake filter for debris, as a clogged screen is the most common cause of reduced spray pressure. Keeping the unit clean and stored in a dry, shaded area will extend its functional life by several years.
Common Operational Mistakes
New users often struggle with speed control, which is the primary cause of uneven chemical application. Maintaining a consistent speed—usually around 3 to 4 miles per hour—is essential for accurate calibration. Another frequent error is failing to calibrate the sprayer before the first use; you must calculate your output to ensure you are not over-applying herbicides, which can kill your grass. Additionally, never skip the pre-spray inspection of your nozzles; a single blocked nozzle can ruin the entire application pattern, leading to strips of weeds left behind while the rest of the lawn is treated correctly.

Frequently Asked Questions
How do I calibrate my tow-behind sprayer for accurate chemical application?
Calibration is vital to ensure you apply the correct amount of chemical per thousand square feet. First, measure a 100-foot test strip and time how long it takes to drive it at your desired speed, typically 3 mph. Then, spray into a container for that exact duration while stationary to measure the output volume. Use this data to calculate your gallons per acre, adjusting your tractor speed or pressure settings accordingly. Always consult the product label on your herbicide or fertilizer for the recommended application rate to avoid damaging your lawn through over-application or failing to kill weeds due to under-application.
Can I use a tow-behind sprayer with a zero-turn mower?
Yes, most tow-behind sprayers are compatible with zero-turn mowers, provided the mower is equipped with a hitch plate. However, because zero-turns are highly maneuverable, you must be careful when making sharp turns with a full tank, as the weight can cause the sprayer to jackknife or tip over. Always drive slowly when turning and avoid sudden stops that could cause the liquid inside the tank to surge. Ensure your hitch is properly secured and that the sprayer's weight does not exceed the manufacturer's recommended towing limit for your specific mower model to maintain safe operation.
What is the best way to clean the tank after using herbicides?
Cleaning is essential to prevent cross-contamination, especially if you switch between herbicides and liquid fertilizers. Start by rinsing the tank thoroughly with clean water, then fill it with a mixture of water and a dedicated tank cleaner or a mild household detergent. Run the pump to circulate this solution through the boom and the spray wand for several minutes. Finally, flush the system with clean water until no suds or odors remain. Always dispose of the rinse water in an area where it won't harm plants or runoff into storm drains, following all local environmental regulations for chemical disposal.
Why is my spray pattern uneven or streaky?
An uneven pattern usually indicates a clogged or worn nozzle, or incorrect boom height. First, check all nozzles for debris; even a small particle can disrupt the spray fan. If the nozzles are clean, ensure they are all oriented at the same angle to provide uniform overlap. If the boom is mounted too low, the spray won't reach across the full width, while mounting it too high can cause wind drift and inconsistent coverage. Check your nozzle spray angle and ensure your tractor speed remains constant, as variations in speed are the most frequent cause of streaks in lawn chemical applications.
How do I prevent the pump from burning out?
The most common cause of pump failure is running it dry or allowing it to overheat during prolonged use. Always ensure there is sufficient liquid in the tank before activating the pump. If you are spot-spraying for an extended period, periodically turn the pump off to let it cool down, especially on hot days. Additionally, ensure your battery connections are clean and tight to prevent electrical resistance, which can cause the motor to work harder than necessary. Using an inline fuse is also a smart safety precaution to protect the pump motor from electrical surges that can occur during operation.
Are these sprayers safe for applying liquid fertilizers?
Yes, tow-behind sprayers are excellent for applying liquid fertilizers, but you must ensure your equipment is specifically rated for the chemicals you are using. Some fertilizers are corrosive, so choosing a unit with a high-density polyethylene tank and stainless steel hardware is crucial for longevity. Always filter your fertilizer solution before adding it to the tank to prevent clogging the pump or nozzles with undissolved granules. After application, perform a thorough system flush to prevent residue buildup, which can harden inside the hoses and cause significant blockages that are difficult to clear once they have fully dried.
How much weight will I be towing when the tank is full?
A gallon of water weighs approximately 8.3 pounds. Therefore, a 15-gallon tank adds about 125 pounds, plus the weight of the sprayer frame itself, while a 31-gallon tank adds over 250 pounds of liquid weight. You must check your tractor's owner manual for its maximum towing capacity, especially when operating on slopes. Towing a heavy, full tank on an incline can put significant strain on your mower's transmission and braking system. Always prioritize safe weight distribution and avoid filling the tank to its maximum capacity if you are working on hilly terrain or uneven ground.
Do I need to worry about wind drift when spraying?
Wind drift is a major concern when using a broadcast sprayer, as it can cause chemicals to land on non-target plants, such as your flowers or your neighbor's lawn. Avoid spraying on windy days; early morning or late evening, when the air is typically calmest, is the ideal time for application. If you must spray in light breeze conditions, use a lower boom height and consider using drift-reduction nozzles that produce larger, heavier droplets. Always be mindful of your surroundings and maintain a buffer zone around sensitive garden areas to ensure your lawn treatments remain exactly where you intend them to be.
