NorthStar Tow-Behind Trailer Boom Broadcast Sprayer
Best for mobile large-area spraying on lawns and fields where a tow-behind setup is preferred. The NSQ Series on-demand pump delivers 2.2 GPM at 70 PSI with a 100% continuous-duty rating, enabling long runs between fills. The 120-inch boom offers broad coverage with independent left/right nozzle control, allowing selective treatment. The 21-gallon UV-resistant tank and rugged steel cart with 12-inch pneumatic wheels support durable field use.
Who it’s best for: contractors and property managers who need a durable, fast-acting system with broad 120-inch coverage. Why selected: strong pump performance and a wide spray footprint help maximize efficiency on larger terrains. Caution: smaller tank capacity means more frequent refills on very large jobs.
NorthStar ATV Broadcast and Spot Sprayer
Best for medium-sized properties and fieldwork where an ATV-compatible system is advantageous. This sprayer features a 26-gallon tank and a 6.7-foot spray swath with a 2-nozzle boom and independent left/right control. The NSQ Series pump provides consistent 2.2 GPM at 70 PSI with a 100% continuous-duty rating for stamina in long jobs. Spring-loaded breakaway arms protect the boom in rough terrain.
Who it’s best for: turf managers and small-acreage farmers needing a balance of capacity and mobility. Why selected: better for mid-size areas than 21-gallon tow systems while offering precise coverage via independent nozzle control. Limitation: slightly smaller spray width than the 120-inch options, requiring more passes on large sites.
Ag Spray Equipment 65 Gallon UTV Sprayer
Best for larger properties and challenging terrain where a bigger tank reduces refill stops. The 65-gallon tank is built with a heavy-duty roto-molded design, offering durability and chemical resistance. A 7-nozzle folding boom delivers up to 11.6 feet of spray coverage with air-induction technology to minimize drift. The 12V pump provides reliable performance for liquid applications across fields and pastures.
Who it’s best for: large lawns, every-acre projects, and operations needing longer spraying windows. Why selected: high capacity paired with a wide spray footprint improves efficiency on expansive sites. Caution: not all chemical formulations compatibility is specified—check compatibility with your products before use.
VANPET 6-Nozzle 122″ Boom Wand Kit
Best for upgrading existing ATV/UTV sprayers to rapid, wide-area coverage. This 122-inch boom kit expands spray reach with six independently controlled nozzles, each with adjustable flow. It uses a direct 3/8″ hose connection, simplifying installation on compatible equipment. The kit reduces the number of passes needed for large plots and allows precise zone targeting.
Who it’s best for: operators seeking to extend reach on established sprayers without purchasing a new full sprayer. Why selected: wide 122″ coverage combined with individual nozzle control improves efficiency. Limitation: kit compatibility depends on existing pump pressure and mounting points.
Master Mfg 6-Nozzle Folding Broadcast Boom Kit
Best for light-to-medium duty applications requiring a compact folding boom. This kit offers six flat-fan nozzles with a 10-foot swath and a pressure regulator, allowing controlled spray flow. The included boom shut-off valve helps conserve chemical and reduce drift. It’s designed for quick attachment and easy transport on compatible platforms.
Who it’s best for: users needing a cost-effective, foldable solution for moderate-sized jobs. Why selected: compact footprint and straightforward setup make it a practical upgrade. Caution: reach is narrower than 122″ options, so more passes may be needed on large areas.
Buying Guide: Key Considerations for a 300-Gallon Sprayer With Booms
Capacity vs. coverage: On large sites, a bigger tank reduces refill frequency but may add weight and size. Decide if you prioritize fewer refills (larger tanks) or easier maneuverability (smaller tanks with wider booms).
Boom design and control: Independent nozzle control and breakaway booms protect against damage. Consider spray width (footage) and ease of folding for transport and storage.
Pump performance and durability: A continuous-duty pump ensures long spraying sessions without overheating. Look for materials that resist chemicals and UV exposure for longevity.
Mounting and compatibility: Tow-behind vs. ATV/UTV-compatible models affect mobility and terrain handling. Ensure mounting points, hoses, and fittings match your existing equipment.
Spray system features: Bypass flow, vented tanks, and washout access improve mixing consistency and maintenance. Check compatibility with your typical herbicides, pesticides, and fertilizers.
Frequently Asked Questions
- What size tank is best for large properties?
For very large sites, consider 65 gallons or larger to minimize refills, while ensuring the sprayer remains manageable on your equipment.
- Is a 120-inch boom necessary?
Not always. A 120-inch boom provides wide coverage, but for smaller properties a 60–80 inch boom may be more practical and easier to maneuver.
- Do I need a breakaway boom?
Yes, breakaway booms reduce damage from impact and preserve alignment, especially on uneven terrain.
- Can I use any chemical with these sprayers?
Check the tank material and compatibility with the chemical products you plan to apply to avoid corrosion or damage.
- Which sprayer is best for ATV use?
ATV-compatible models are designed for lighter loads and improved mobility, ideal for smaller farms or properties with rough terrain.
