NorthStar Tow-Behind Trailer Boom Sprayer
The NorthStar Tow-Behind Sprayer combines a sizable 21-gallon tank with a high-performance 12V 2.2 GPM on-demand pump. Its 70 PSI maximum provides robust coverage for lawns, farm plots, or landscaped areas. The Santoprene diaphragm and Viton valves ensure chemical resistance and long life, making this model suitable for herbicides, fertilizers, and broadleaf control. The unit is designed for continuous operation with a 100% duty rating, reducing the need for frequent stops during large jobs.
Agri-Fab Tow-Behind Sprayer With Boom
Agri-Fab offers a practical 15-gallon tank with a reliable 100 PSI sprayer pump and a flow rate of 1.6 GPM. The included boom and spray wand enable both broadcast coverage and targeted applications. Molded fill indicators help operators prepare the right mix, while check valves in boom tips prevent siphoning and dripping. This balance of capacity and precision makes it a strong choice for homeowners managing weed growth across moderate acreage or yard spaces.
25 Gallon Pull-Behind Sprayer With 7′ Swath
Guardian’s 25-gallon pull-behind unit is designed for larger properties, offering a 7-foot broadcast swath and the ability to spot spray up to 20 feet horizontally. Its translucent tank with raised volume markings makes it easy to monitor residue levels and plan refills. The generous capacity reduces downtime on big jobs, and the sprayer’s contour and boom setup support uniform application across uneven terrain.
PetraTools 3 Gallon Battery Sprayer
PetraTools offers a compact, battery-powered backpack sprayer with 3 gallons of capacity and up to 80 PSI. While not a tow-behind unit, it provides a complementary option for spot treatments or areas where a tow-behind system may be impractical. It includes multiple nozzles and padded straps for user comfort, making it a practical add-on for precise weed control in smaller zones or around obstacles.
Buying Guide: Key Purchase Considerations
When choosing a tow-behind weed sprayer with a boom, consider the following factors to match your property, climate, and treatment needs:
- Capacity and spray pattern: Larger tanks reduce refill frequency on big properties but add weight and fuel consumption. A 7-foot swath expands broadcast coverage, while spot spray capabilities target stubborn weeds.
- Pump type and flow: A high-flow, on-demand pump (like 2.2 GPM) accelerates spraying on wide areas, but ensure compatibility with the chemicals you use. Check for pump materials resistant to common herbicides and fertilizers (e.g., Santoprene, Viton).
- Pressure range: Higher PSI supports more robust broadcast over uneven terrain, but lower PSI can help with precision and reduced drift. Look for models rated for continuous duty if you plan long spraying sessions.
- Boom construction and durability: A well-built boom with properly sealed nozzles reduces leaks and maintenance. Boom tip check valves help prevent siphoning and dripping.
- Tank material and visibility: Transparent or translucent tanks with volume markings simplify mix calculations and monitoring during applications.
- Mounting and hitch compatibility: Verify that the sprayer mates with your trailer or hitch setup and remains stable on slopes or rough surfaces.
- Maintenance and parts availability: Choose brands with widely available replacement parts and service options to minimize downtime.
- Included accessories: Wands, nozzle configurations, and filtration systems influence how effectively you can tailor spraying to lawns, gardens, or tight landscaping.
For best results, match a sprayer’s features to your typical property size, weed species, and preferred spraying technique. Larger capacity and wider swaths suit expansive properties, while precise spot spray capability is valuable for borders, driveways, or gardens with delicate plantings. Always follow label directions for chemical compatibility and safe operation.
