Tow-Behind Trailer Boom Broadcast and Spot Sprayer - 31-Gallon

Our review of the NorthStar tow-behind boom and spot sprayer finds it best suited for homeowners and small acreage managers who need a reliable, large-capacity sprayer for trees, shrubs and broadcast applications. The single biggest reason to consider this unit is its combination of a roomy, UV-resistant 31-gallon tank and a 12V, 2.2 GPM NorthStar NSQ on-demand pump that primes quickly and is rated for continuous duty. Installation and basic operation are straightforward, and the sprayer uses durable materials where it matters most for chemical resistance and frequent use.

Key Features

• 31-Gallon Tank: The large proprietary tank with extra-thick walls reduces refill frequency and resists UV degradation for longer outdoor life.
• 12V 2.2 GPM Pump: The NSQ Series open flow pump provides faster priming and steady flow for broadcast and spot spraying at up to 70 PSI.
• Continuous Duty Rating: A 100% continuous duty rating means the pump is designed for extended runs without overheating during typical yard or orchard work.
• Chemical-Resistant Components: Santoprene diaphragm and Viton valves offer improved resistance to a wide range of pesticides and liquids used in lawn and garden care.
• Durable Switch: The Honeywell micro switch improves operational reliability and helps the pump run efficiently under load.

Who It's For

The sprayer is ideal for homeowners with several trees or garden beds, small farmers, and landscapers who need a tow-behind unit that handles both boom broadcast and spot applications without frequent refills. Its 31-gallon capacity and continuous duty pump suit jobs that require steady application over moderate acreage.

Those who need ultra-heavy commercial use on many acres or expect military-grade ruggedness may want to compare purpose-built agricultural tractors or higher-end commercial systems; the sprayer is built for value and everyday garden and small-acre tasks rather than industrial farm use.

Pros & Cons

Pros

• Large, UV-resistant tank reduces refill interruptions and resists sun damage.

• Clear value for money with quality parts like the Honeywell micro switch in the control circuit.

Cons

• Some users report occasional leakage or early pump failure, so inspect fittings and test before extended use.
• The wand and some peripheral parts may feel less rugged than the core pump and tank components.
