NorthStar Tow-Behind 31-Gallon NSQ Field Sprayer
The NorthStar 31-gallon NSQ Series sprayer uses a commercial-grade on-demand pump delivering 2.2 GPM at up to 70 PSI. It features a spring-loaded breakaway boom with a wide 120-inch spray width and independent left/right nozzle control for precise coverage. The 31-gallon UV-resistant tank is mounted on a powder-coated steel cart with 12-inch pneumatic wheels for stability on uneven work sites. This configuration is best for professionals tackling long days of field spraying where durability and wide-area coverage matter most. Choose this if you need higher flow, large tank capacity, and robust construction for frequent use. Caution: the system relies on a single-pump design; ensure ongoing maintenance to prevent downtime on active jobs.
- Best for: Professional lawn, pasture, and field applications requiring wide coverage and rugged build.
- Why selected: High-capacity tank, continuous-duty NSQ pump, and durable spring-loaded boom.

This model uses the same NSQ on-demand pump platform but with a 21-gallon tank. It delivers 2.2 GPM at 70 PSI and includes a 120-inch boom with independent nozzle control. The smaller tank helps reduce trailer weight while maintaining wide spray capability. Best for medium-sized properties or contractors needing faster turnarounds between jobs. Better for: lighter-to-moderate workloads where mobility and fuel efficiency matter. Limitation: reduced tank capacity compared with the 31-gallon version, so more frequent refills may be required on larger tasks.

This option suits small to medium yard tasks where a balanced payload and manageable size are important. Buy this if you want a compact, cost-effective sprayer for regular lawn and garden use. Caution: lower tank capacity may require more frequent refills on larger properties.
- Best for: Homeowners with smaller lots or light-to-moderate spraying needs.
- Why selected: Compact, affordable, and practical for frequent use on small to mid-size properties.

Choose this if you need a lightweight, straightforward sprayer. Limitation: smaller tank capacity and lower flow rate limit continuous coverage on larger properties.
- Best for: Small lawns, gardens, and light weed-control tasks.

Buying Guide
Key purchase considerations help ensure you pick a pull-behind sprayer that matches your land size, typical spray width, and vegetation control needs.
- Tank capacity vs. job size: Larger tanks reduce refill frequency but add weight. Choose based on your field size and typical spray intervals.
- Pump type and duty cycle: Continuous-duty pumps avoid downtime on long projects. Look for diaphragm-style on-demand pumps for chemical compatibility and endurance.
- Spray width and boom design: Wider booms speed coverage but may require more precise steering. Independent nozzle controls offer targeted applications along borders and obstacles.
- Wheels and frame: Larger, pneumatic tires improve stability on uneven ground. A powder-coated steel frame resists corrosion and chemical exposure.
- Material compatibility: If you spray Roundup or similar herbicides, ensure tank material resists cracking and chemical degradation.
