Tow-Behind Trailer Boom Broadcast and Spot Sprayer - 21-Gallon

In this review of the Tow-Behind Trailer Boom Broadcast and Spot Sprayer, the reviewer finds it a practical choice for homeowners and small-acreage operators who need a reliable, easy-to-use sprayer for broadcast and spot applications. The single biggest reason to buy is the combination of a well-designed 21-gallon tank and a robust 12V 2.2 GPM NSQ Series pump that primes quickly and supports continuous use, making it suitable for treating lawns, pastures, and larger gardens without frequent refills.

Key Features

• 21-Gallon Tank: The large-capacity proprietary tank reduces refill frequency so users can cover more ground between stops.
• 12V 2.2 GPM Pump: The NSQ Series on-demand pump delivers faster priming and steady flow for consistent spray performance across varied tasks.
• Durable Materials: Santoprene diaphragm and Viton valves provide chemical resistance and longer life when using a broad range of pesticides and solutions.
• Boom Coverage: The boom provides 120in overall width with about 80in effective spray width for efficient broadcast spraying of medium-sized areas.
• Continuous Duty Rating: A 100% continuous duty rating and up to 70 PSI maximum allow extended runs without overheating or loss of pressure.

Who It's For

This sprayer is best for homeowners with large lawns, hobby farms, and small acreage owners who need to treat turf, weeds, or apply liquid fertilizer across 1-3 acres at a time. The tow-behind setup and boom make it a good fit for tractors, ATVs, and utility vehicles used by landscapers or property managers who value coverage and fewer trips to refill.

It is less appropriate for someone who requires heavy industrial duty cycles or who frequently sprays highly abrasive or particulate-filled mixes not recommended for diaphragm pumps. Customers who prioritize ultra-heavy-duty commercial gear or complex, certified agricultural sprayers should consider higher-spec commercial models.

Pros & Cons
