1. Fimco 40 Gallon 3-Point Sprayer: Best Overall
The Fimco 40 Gallon 3-Point Sprayer stands out for its robust construction and reliable performance. The poly tank is UV-stabilized and resistant to chemical corrosion, ensuring longevity. The diaphragm pump delivers a steady 2.5 GPM at up to 45 PSI, which is sufficient for most lawn and pasture applications. The 60-inch boom with three adjustable nozzles provides consistent coverage, and the handgun is useful for spot spraying. Based on owner feedback, assembly is straightforward and the unit tows smoothly.
However, this sprayer is heavy when filled with 40 gallons of liquid, weighing over 300 pounds. It may be too much for smaller lawn tractors or ATVs with limited towing capacity. Users with hilly terrain should also be cautious about stability. If you have a larger property and a capable vehicle, this is a top choice. But those with smaller lawns or lighter equipment might prefer a smaller model.
- Durable poly tank resists UV and chemicals
- Diaphragm pump provides consistent pressure up to 45 PSI
- 60-inch boom with adjustable nozzles for even coverage
Pros: Excellent build quality and corrosion resistance; Easy to assemble and attach to most ATVs and lawn tractors
Cons: Heavy when full, may require a larger mower
2. Chapin 20039 25 Gallon Tow Behind Sprayer: Best Value
The Chapin 20039 is a well-rounded pull behind sprayer that offers excellent value for small to medium properties. The 25-gallon tank is manageable for most lawn tractors, and the diaphragm pump provides adequate pressure for general lawn care. The 40-inch boom with three nozzles gives decent coverage, and the included handgun is handy for targeting weeds. Based on owner feedback, the unit is easy to assemble and tows well on flat terrain.
However, the 25-gallon capacity means you’ll need to refill more often on larger areas, and the plastic frame may not hold up as well as steel over many years. Some users reported the hose connections can be prone to leaks if not tightened properly. If you have a small to medium lawn and want a budget-friendly option, this is a solid choice. But for heavy-duty use or larger acreage, a larger model may be more suitable.
- Compact size ideal for 1-2 acre properties
- Diaphragm pump with 40 PSI max pressure
- Includes handgun for spot spraying
Pros: Great value for the price point; Easy to maneuver and store
Cons: Smaller tank requires more frequent refills
3. NorthStar 25 Gallon Tow Behind Sprayer: Premium Build
The NorthStar 25 Gallon Tow Behind Sprayer is built to last with a heavy-duty steel frame and a powder-coated finish that resists rust. The diaphragm pump produces 2.2 GPM at up to 60 PSI, making it effective for both spraying and reaching tall vegetation. The 42-inch boom has adjustable height and three nozzles, and the handgun is included. Owner feedback highlights the solid feel and consistent performance.
On the downside, this sprayer is more expensive than comparable 25-gallon models, and the steel frame adds weight. Some users found the assembly instructions lacking detail. If you prioritize durability and have a larger budget, this is an excellent choice. However, for occasional use on a small lawn, the extra cost may not be justified.
- Heavy-duty steel frame with powder coat finish
- Pump delivers 2.2 GPM at up to 60 PSI
- Adjustable boom height for different terrain
Pros: Very durable construction; High pressure for tough applications
Cons: Higher price point
4. Agri-Fab 45-0463 15 Gallon Tow Sprayer: Compact & Light
The Agri-Fab 45-0463 is a compact and lightweight pull behind sprayer ideal for small properties. The 15-gallon tank is easy to handle, and the piston pump delivers 1.1 GPM at up to 40 PSI, sufficient for basic lawn spraying. The 36-inch boom with three nozzles covers a narrow path, and the unit is very easy to assemble and store. Owner feedback often praises its simplicity and value.
However, the piston pump is less durable than diaphragm pumps and may require more frequent replacement. The low flow rate and pressure make it unsuitable for tall weeds or large areas. The plastic wheels can also struggle on rough terrain. If you have a small, flat lawn and want an inexpensive sprayer, this works. But for anything more demanding, you’ll want a larger model.
- Ultra-lightweight, easy to tow with small tractors
- Piston pump is simple to maintain
- Compact size for tight storage
Pros: Very affordable; Great for small lawns (under 1 acre)
Cons: Lower pressure and flow rate
5. Fimco 15 Gallon ATV Sprayer: ATV Optimized
The Fimco 15 Gallon ATV Sprayer is primarily designed for ATV mounting but can be used as a tow behind with an optional hitch adapter. It features a durable poly tank and a diaphragm pump that delivers 1.5 GPM at up to 45 PSI. The 42-inch boom provides good coverage, and the handgun with a 20-foot hose is convenient for spot spraying. Owner feedback notes that it works well on ATVs and small tractors.
However, the tow hitch adapter is not included, which adds to the cost. The 15-gallon tank is small for larger properties, and the boom is not adjustable in height. Some users reported that the hose connections can leak if not sealed properly. If you have an ATV and want a sprayer that can also be towed, this is a decent option. But for dedicated tow behind use, other models are more convenient.
- Designed for ATV mounting, but works as tow behind
- Diaphragm pump with 45 PSI max
- Includes handgun and 20-foot hose
Pros: Versatile mounting options; Good pressure for its size
Cons: Tow hitch adapter sold separately; Small tank limits runtime
6. Tractor Supply Co. 26 Gallon Tow Behind Sprayer: Mid-Range Workhorse
The Tractor Supply Co. 26 Gallon Tow Behind Sprayer is a solid mid-range option for homeowners with medium-sized lawns. The 26-gallon tank is a good balance between capacity and weight, and the diaphragm pump offers reliable performance. The 40-inch boom with three nozzles provides even coverage, and the handgun is useful for spot treatments. Owner feedback indicates it works well for basic lawn care.
However, the plastic frame and wheels are less durable than steel alternatives, and the boom height is fixed, which can be problematic on uneven ground. Some users experienced pump priming issues. If you need a sprayer for occasional use on a flat lawn, this is a reasonable choice. But for heavy-duty or commercial use, look for a model with a steel frame and adjustable boom.
- Good capacity for medium lawns
- Diaphragm pump provides consistent flow
- Includes handgun and 15-foot hose
Pros: Decent price for the size; Simple assembly
Cons: Plastic frame feels less sturdy; Boom height is not adjustable
7. Brinly BS-40BH Tow Behind Sprayer: Heavy Duty
The Brinly BS-40BH is a heavy-duty pull behind sprayer designed for large properties. The 40-gallon tank and 60-inch boom with five nozzles allow fast coverage, and the diaphragm pump delivers 2.5 GPM at up to 45 PSI. The steel frame is robust, and the pneumatic tires handle rough terrain well. Owner feedback appreciates the capacity and coverage.
However, this sprayer is very heavy when filled, requiring a powerful tractor or ATV. Assembly is more complex than other models, and some users reported issues with the hose fittings. The price is also on the higher side. If you have a large, flat property and a capable vehicle, this can be an efficient tool. But for smaller properties or lighter equipment, it’s overkill and difficult to maneuver.
- Large capacity for big properties
- Wide boom with 5 nozzles for fast coverage
- Diaphragm pump with 45 PSI
Pros: Covers large areas quickly; Sturdy steel frame
Cons: Very heavy when full; Assembly can be challenging
Frequently Asked Questions
How do I choose the right size pull behind sprayer for my mower?
Consider your property size and your vehicle’s towing capacity. For lawns under 1 acre, a 15-25 gallon tank is sufficient. For 1-3 acres, 25-40 gallons works well. Larger properties may need 40+ gallons. Check your mower or ATV’s towing capacity; a full 40-gallon sprayer can weigh over 400 pounds.
What is the difference between a diaphragm pump and a piston pump?
Diaphragm pumps are more durable, can run dry without damage, and handle higher pressures, making them ideal for frequent use. Piston pumps are simpler and cheaper but wear faster and cannot run dry. For most users, a diaphragm pump is recommended.
Can I use a pull behind sprayer for weed killer and fertilizer?
Yes, most pull behind sprayers are designed for both herbicides and liquid fertilizers. However, always clean the tank thoroughly between different chemicals to avoid reactions. Some chemicals may require specific nozzle types for proper application.
How do I maintain my pull behind sprayer?
After each use, flush the system with clean water, especially if you used herbicides. Store the sprayer in a dry place, and winterize by draining all liquid and adding antifreeze if needed. Check hoses and connections regularly for leaks.
What safety precautions should I take when using a pull behind sprayer?
Always wear protective gear (gloves, goggles, long sleeves) when handling chemicals. Ensure the sprayer is securely hitched and safety chains are attached. Never exceed the vehicle’s towing capacity. On slopes, drive carefully to avoid tipping.
