NorthStar Tow-Behind 55-Gallon Sprayer with 7 GPM Pump
The NorthStar 55-gallon tow-behind sprayer combines a large tank with a powerful pump to support substantial spraying tasks. Powered by a 160cc Honda GX160 engine, this model delivers up to 150 PSI and up to 7 GPM flow, enabling faster coverage for larger plots. Its design emphasizes durability with a robust hose layout and reliable pump components, making it suitable for herbicides, fertilizers, and crop protection products. The dual-boom arrangement and precise shutoffs help target areas efficiently, reducing overlap and waste. This unit is ideal for mid-to-large acreage where a higher capacity is essential.
Key considerations
- Capacity and pressure: The 55-gallon tank supports extended spraying; 150 PSI enables dense formulations and longer spray distances.
- Engine power: A dedicated engine provides consistent performance under load, though it adds fuel management considerations.
- Durability: Heavy-duty construction supports frequent field use and rough terrain.
NorthStar 31-Gallon Tow-Behind Sprayer
NorthStar’s 31-gallon model targets efficient coverage with a 2.2 GPM open-flow pump and a 12V on-demand system. With a maximum duty rating and a Santoprene diaphragm plus Viton valves, this sprayer emphasizes reliability and chemical resistance for a variety of products. The 70 PSI maximum helps manage smaller to medium-sized properties with precise application control. Its compact footprint makes trailer-to-field transitions smoother, especially when space is limited or gates are narrow.
Key considerations
- Flow and pressure balance: 2.2 GPM at up to 70 PSI is suitable for general spray tasks and spot applications.
- Electrical system: A 12V on-demand pump simplifies wiring and maintenance in the field.
- Portable design: Lighter overall weight improves towing ease on uneven terrain.
Master Mfg 36-Gallon Premium Pull-Behind
This Master Mfg model emphasizes a balance of capacity and portability for mid-sized properties. The 36-gallon tank supports broader coverage than smaller units and uses an Everflo 3.0 GPM 12V on-demand diaphragm pump. The spray boom provides a 10-foot spray swath with six quick-attach, no-drip nozzles, and the system features a foldable boom for compact storage. The combination of a robust pump and practical storage makes it well-suited for poultry houses, turf, and agricultural plots where consistent coverage matters.
Key considerations
- Swath and nozzle configuration: A 10-foot swath with quick-attach nozzles enhances coverage and reduces set-up time.
- Storage considerations: A foldable boom helps save space in sheds or garages.
- Chemical compatibility: The Everflo pump is designed for reliable 12V operation with common agricultural solutions.

Its vertical, self-storing design requires minimal garage or shed space, making it a practical choice for smaller farms or large residential properties that still demand substantial coverage. The unit supports flexible spraying tasks, from lawn care to garden beds, when space is at a premium.
Key considerations
- Storage footprint: Collapsible booms and self-storing design maximize garage space efficiency.
- Coverage area: 15 gallons is smaller than larger models but can be paired with a wider swath or multiple passes for efficiency.

Buying Guide: How to Choose a Tow-Behind Sprayer for Big Jobs
Selecting the right tow-behind sprayer depends on several factors beyond tank size. Start with field dimensions, target crops, and the products you plan to apply. Consider pump type and capacity to ensure your application rate matches the task. For larger areas, higher tank capacity reduces refill frequency; for smaller plots, portability and maneuverability may take priority.
- Tank capacity and field size: Larger plots benefit from higher capacity, but balance with towing stability and storage space.
- Pump type and flow rate: Diaphragm pumps offer durability with aggressive chemical mixes, while diaphragm-gear pumps provide steady flow at consistent pressures. Match GPM to the spray formula and nozzle configuration.
- Pressure range and nozzle setup: PSI and swath width influence coverage and drift risk. Wide swaths speed up tasks but require careful calibration to avoid over-application.
- Boom design and storage: Collapsible or self-storing booms save space, but ensure the boom is sturdy and easy to deploy in tight spots.
- Chemical compatibility and durability: Look for materials resistant to common agricultural chemicals, including glyphosate and fertilizers.
- Ease of maintenance: Quick-access filter housings, dependable seals, and reliable pumps reduce downtime and maintenance costs.
- Trailer hitch and stability: A stable hitch, balanced weight distribution, and good tires reduce vibration and improve towing on uneven terrain.
When comparing models, prioritize consistency in spray patterns, reliability of the pump, and the ability to perform routine maintenance without specialized tools. For extensive commercial use, models with larger tanks and robust engines may justify the higher upfront cost due to reduced refill cycles and faster application rates. Always follow manufacturer guidelines for chemical compatibility and safety best practices to protect workers and the environment.
