NorthStar Tow-Behind 31-Gallon Sprayer
The NorthStar NSQ Series 31-gallon sprayer uses a commercial-grade NSQ on-demand pump rated at 2.2 GPM and 70 PSI. It features a spring-loaded breakaway boom with a total spray width of 120 inches and independent left/right nozzle control for precise coverage. The 31-gallon tank is UV-resistant and mounted on a heavy-duty powder-coated steel cart with 12-inch pneumatic wheels, making it durable for job sites and uneven terrain. Best for professional-grade lawn care, golf courses, or large properties where wide-area coverage is essential.
Who it’s best for: commercial crews and serious homeowners who spray large yards or fields and need long run times without overheating. Why selected: the NSQ pump design provides continuous duty and fast priming, which reduces downtime between spraying runs. Caution: the pump and valves are designed for chemical compatibility; always verify material compatibility with your spray mix to avoid premature wear.
NorthStar Tow-Behind 21-Gallon Sprayer
This NorthStar model uses the same NSQ on-demand pump platform as the 31-gallon version but with a 21-gallon tank. It delivers 2.2 GPM at up to 70 PSI and features a 120-inch spray width with 80 inches of effective coverage. The breakaway boom and independent nozzle control help you tailor applications on lawn beds, fence lines, and tight borders. Best for mid-sized properties and contractors who need fast, precise spraying without a large tank, this model balances capacity with maneuverability.
Who it’s best for: contractors and homeowners who want robust performance in a smaller footprint. Why selected: the 21-gallon setup keeps weight manageable while still offering the same durable NSQ pump and breakaway boom. Caution: with smaller tanks, refill intervals occur more often on large properties; plan for refills to minimize downtime.
Master Mfg 36-Gallon Premium Pull-Behind Sprayer
The Master Mfg 36-Gallon sprayer uses an Everflo 3.0 GPM 12V on-demand diaphragm pump to deliver steady flow. The system provides a 10-foot spray swath with quick-attach, no-drip nozzles and a compact storage-ready boom that folds horizontally. This setup suits mid-size lawns, orchards, and farms where ease of storage and reliable pumping are priorities. Best for users who want a larger tank than compact units but still require easy storage and straightforward maintenance.
Who it’s best for: homeowners with substantial property and occasional professional use, or small-to-medium farms. Why selected: higher flow rate and a foldable boom offer faster coverage with easier storage. Caution: the 10-foot swath is narrower than some heavy-duty models; plan for larger landscapes or multiple passes where needed.
Chapin 15-Gallon Tow-Behind Sprayer
The Chapin 15-Gallon Tow-Behind sprayer is a USA-made option built on a powder-coated steel frame with 12-inch pneumatic tires for rough terrain. The 15-gallon tank provides visibility through a translucent poly design, with a 6-inch fill opening and an interior filter basket cap to limit debris. This model is positioned for garden beds, small lawns, and light-duty weed control where a lighter, more maneuverable rig is advantageous.
Who it’s best for: small property owners and renters who need occasional spray capabilities without a heavy machine. Why selected: simplicity and rugged build make maintenance straightforward. Caution: smaller tank means more frequent refills; good for smaller plots or shorter spraying sessions.
Agri-Fab 60-Gallon Tow-Behind Sprayer
The Agri-Fab 60-Gallon sprayer features a REMCO 100 psi, 4 GPM diaphragm pump and a 60-gallon tank designed for heavy-duty use. A hand-wand with a 19-foot hose extends reach to hard-to-access areas, and the boom includes check valves at the tips to prevent siphoning and dripping. Best for larger landscapes, commercial properties, and agricultural tasks that demand higher flow and longer run times. This model shines when you need substantial capacity and flexibility on varied terrain.
Who it’s best for: larger properties and contractors performing frequent spray work or application across expansive areas. Why selected: high capacity and strong pumping power support pro-level workloads. Caution: heftier machine requires careful handling and proper towing vehicle compatibility; verify hitch and tongue weight before use.
Buying Guide: Tow-Behind Liquid Sprayer Essentials
What size tank should I choose? Consider property size, typical spray area, and refill frequency. Larger tanks reduce downtime but add weight and may require a sturdier tow vehicle or tractor. For lawns up to a few acres, 15–36 gallons is often sufficient. For commercial or pasture work, 60 gallons or more can save time.
Which pump type is best? On-demand diaphragm pumps (like NSQ and Everflo) offer reliable flow with good chemical compatibility and continuous duty. They’re preferred for professional workloads. Always check the pump’s GPM, PSI, and duty cycle to match your spray patterns and chemical mixes.
What about spray width and nozzle control? A wider spray width speeds coverage, but you’ll want independent nozzle control for edges and tight spaces. Spring-loaded breakaway booms protect against impacts and are useful in uneven terrain. Consider whether you need foldable or self-storing booms for easier storage.
What materials matter? Tanks with UV resistance and chemical compatibility extend service life, especially when using harsh herbicides or fertilizers. A durable powder-coated steel frame supports long-term outdoor use, while translucent tanks help monitor liquid levels quickly.
What safety and maintenance considerations apply? Inspect hoses, valves, and seals regularly. Ensure proper mounting and hitching to your tow vehicle. Use manufacturer-recommended cleaners and rinse cycles after chemical applications to prevent residue buildup and corrosion.
FAQ
What is the advantage of an on-demand pump?
On-demand pumps deliver consistent flow and reduce heat buildup, allowing longer spraying sessions without cooldown breaks.
Can I spray Roundup or other herbicides with these sprayers?
Yes, most models specify compatibility with common agricultural herbicides, but always verify chemical compatibility with the pump, seals, and tank materials before use.
Is a larger tank always better?
Not always. Larger tanks reduce refill stops but add weight and may require a more capable tow vehicle. Choose based on your property size and riding equipment.
Do these sprayers fold up for storage?
Many models feature foldable or self-storing booms, which saves space in sheds or garages. Check the product’s storage design before purchase.
What maintenance is essential after spraying?
Rinse the tank and lines thoroughly, inspect nozzles for clogs, and check seals and fittings for wear. Store with a residual rinse to prevent chemical buildup.
Which model is best for a small garden?
For small gardens, a lighter 15–21 gallon unit with easy maneuverability and simple controls can be ideal, such as the Chapin 15-Gallon Tow-Behind Sprayer.
