NorthStar Tow-Behind 31-Gallon NSQ Sprayer
This commercial-grade sprayer uses the NSQ on-demand pump delivering 2.2 GPM at up to 70 PSI with continuous duty. It combines a heavy-duty, UV-resistant 31-gallon tank with a powder-coated steel chassis and 12-inch pneumatic wheels for stability on uneven terrain. Best for large lawns or properties needing frequent, high-volume applications. Choose this if you regularly treat extensive areas and require dependable prime-and-spray performance.
Best for: larger properties, frequent use, wide-area coverage. Why chosen: robust NSQ pump, wide 120-inch boom, and independent nozzle control provide precise, efficient coverage. Caution: the assembly is heavier and may require a bigger tow installation and maintenance space.
NorthStar Tow-Behind 21-Gallon NSQ Sprayer
The 21-gallon version uses the same NSQ pump and a 120-inch boom with independent left/right nozzle control. It provides strong performance for mid-sized lawns and properties with varied terrain. Best for: property owners who need wide coverage without the footprint of the largest models. Why chosen: excellent mix of flow, duty cycle, and maneuverability. Limitation: slightly smaller tank means more frequent refills on very large jobs.
Chapin 97084 Tank Sprayer – 8 Gallon
Designed for ATV/UTV use with a compact 8-gallon tank, this sprayer emphasizes mobility and simple operation. It features a 12V hookup and a 1 GPM diaphragm pump for steady spray output. Best for: homeowners with smaller lawns or tight spaces where maneuverability matters. Why chosen: convenient for quick, spot treatments and lighter-duty herbicide or fertilizer tasks. Caution: smaller tank means more frequent refills on larger properties.
Chapin 97154 Tank Sprayer – 15 Gallon
This 15-gallon model adds triple filtration to help prevent clogs, with a 12V diaphragm pump and a long 15-foot reinforced hose. Best for: mid-sized lawns or properties where a consistent spray is needed, and frequent refilling is acceptable. Why chosen: robust filtration chain reduces downtime due to clogs. Limitation: filtration can add cost and maintenance steps compared to simpler designs.
Master Mfg 15-Gallon ATV Spot Sprayer
This spot sprayer features a 15-gallon tank and a 7-foot spray swath with an all-steel broadcast boom. Best for: focused weed control along fence lines, around trees, and small to mid-sized lawns. Why chosen: good balance between capacity and maneuverability for targeted applications. Caution: best used with compatible nozzles and careful calibration to avoid over-application.
Ironton 26-Gallon ATV Spot Sprayer
The 26-gallon tank provides extended coverage for larger properties, with a 2.1 GPM on-demand pump and a 60 PSI auto shutoff. Best for: moderate to large properties needing long spray runs with a reliable shutoff to conserve chemical use. Why chosen: higher capacity reduces stops for refills, while the auto shutoff controls spray precision. Limitation: taller tanks can affect weight distribution on steeper slopes.
Buying Guide
What size tank is right for me?
Consider property size, expected refill frequency, and vehicle towing capacity. Larger yards benefit from 21–31 gallon tanks; smaller lawns may do well with 8–15 gallons to keep the system nimble.
Do I need a boom with independent nozzle control?
Yes if you treat uneven areas or need precise edge coverage. Independent left/right nozzle control helps tailor spray to borders, fences, and mulch beds without overspray.
What pump type should I look for?
Diaphragm pumps with 12V operation are common for lawn sprayers. Look for models with 100% continuous-duty rating for long job runs and durable diaphragms and valves for chemical resistance.
What features improve field reliability?
Durable frames, UV-resistant tanks, corrosion-resistant fittings, and secure, wide wheels improve on-field reliability. Look for spring-loaded breakaway booms to withstand obstacle impacts without damage.
What maintenance steps matter most?
Regularly inspect hoses and seals, clean the filter, and monitor chemical compatibility with the tank material. Properly storing in a dry area after use helps prolong life.
Frequently Asked Questions
- What is the best tank size for a typical residential lawn? A tank in the 8–15 gallon range handles most mid-sized lawns with less reloading, while larger properties may benefit from 21–31 gallons for fewer stops.
