Best 15-Gallon Sprayer Trailers and Tow-Behind Options
The best 15-gallon sprayer trailer depends on whether you need a complete tow-behind sprayer or a kit to convert or configure equipment you already own. The FIMCO and CHAPIN 97664 are complete tow-behind options; the Wutist is a trailer kit for compatible spot sprayers. The CHAPIN 97154 is an ATV/UTV-mounted sprayer rather than a trailer, while Master Manufacturing’s kit is a boom-mounting component, not a complete sprayer.

FIMCO 15-Gallon Trailer Sprayer

The FIMCO is the clearest match for shoppers seeking a complete 15-gallon sprayer trailer. Its listed specifications include a two-nozzle boom, a 1.2 GPM pump, and 60 PSI. Those details make it easier to compare with other complete units when boom coverage and pump output are priorities.
- Best for: Buyers who want a 15-gallon tow-behind sprayer with a boom included.
- Why it stands out: The product listing identifies the tank capacity, two-nozzle boom, flow rate, and pressure.
- Limitation: The listed pump flow is 1.2 GPM; compare that specification with the needs of your spraying task before choosing.
Choose this if you want a defined, all-in-one trailer-sprayer configuration rather than a separate trailer kit. The available product details do not specify additional accessories or towing requirements.
CHAPIN 97664 Tow-Behind Sprayer

The CHAPIN 97664 is a 15-gallon tow-behind sprayer designed for use behind an ATV or UTV. Its listed features include a two-nozzle boom and a pump described in the product name as 25 GPM. Confirm the pump specification in the current product details if flow rate is a deciding factor.
- Best for: ATV or UTV owners who want a tow-behind sprayer with a two-nozzle boom.
- Why it stands out: It combines a 15-gallon tank and boom-equipped towing format.
- Limitation: It is intended to be towed behind an ATV or UTV; the provided listing does not establish suitability for other towing vehicles.
Compared with the FIMCO, this model is specifically presented for ATV/UTV towing. Compare the pump information and intended vehicle use before deciding between the two.
Wutist Sprayer Trailer Kit

The Wutist product is a trailer kit, not a complete sprayer. It is described as compatible with 15- and 25-gallon spot sprayers and has a steel, powder-coated construction. That makes it an option for buyers who already have a compatible sprayer and need a trailer assembly.
- Best for: Owners of compatible 15- or 25-gallon spot sprayers who want a trailer kit.
- Why it stands out: Its stated compatibility covers two common tank sizes, and the listing identifies powder-coated steel construction.
- Limitation: A sprayer is not identified as included. Verify fit with your exact sprayer before purchase.
Choose this instead of a complete unit only if you already have a compatible tank-and-sprayer setup. The provided details do not list assembly dimensions or other included components.
CHAPIN 97154 ATV/UTV Sprayer

The CHAPIN 97154 has a 15-gallon capacity, a 12V pump, triple filtration, and a 15-foot hose. It is described as an ATV/UTV sprayer, not a tow-behind trailer. It belongs in this comparison as an alternative for buyers who want vehicle-mounted equipment rather than a trailer.
- Best for: Buyers who want to operate a sprayer from an ATV or UTV and value a 15-foot hose.
- Why it stands out: The listing calls out the 12V pump and triple filtration.
- Limitation: It is not listed as a trailer, so avoid it if towing a separate sprayer is essential.
Choose this if direct vehicle mounting better fits your work pattern. Compare its configuration with a tow-behind model before assuming it offers the same mobility or coverage method.
Master Mfg Directional Boom Kit

The Master Mfg product is a directional trailer sprayer boom mounting kit. It is a component rather than a complete sprayer or trailer. Consider it when your need is specifically boom mounting and you have already confirmed that the kit suits your sprayer setup.
- Best for: Buyers seeking a directional boom mounting component.
- Why it stands out: Its stated purpose is focused on mounting a sprayer boom.
- Limitation: The listing name does not specify tank capacity, pump, or included sprayer equipment.
Avoid this as a standalone solution if you need a ready-to-use 15-gallon trailer sprayer. Check the product details for fit and included hardware before selecting a mounting kit.
Buying Guide: How To Choose A 15-Gallon Sprayer Trailer
Do you need a complete sprayer or a trailer kit?
A complete unit such as the FIMCO or CHAPIN 97664 combines a tank and spraying components in a tow-behind format. A trailer kit such as the Wutist is for buyers who already own a compatible sprayer. A boom-mounting kit is a component only. Check what is included so you do not mistake a kit for a ready-to-use sprayer.
Will you tow it or mount it on your vehicle?
Choose a tow-behind model if you want the sprayer to follow an ATV or UTV. The CHAPIN 97154 is described as an ATV/UTV-mounted sprayer, making it a different format rather than a direct trailer substitute. Match the product’s stated use to your vehicle and work setup.
Which pump and boom details should you compare?
Compare the specifications actually provided, including pump flow, pressure, and number of boom nozzles. The FIMCO listing specifies 1.2 GPM, 60 PSI, and two nozzles. The CHAPIN 97664 lists a two-nozzle boom and a 25 GPM pump in its product name; verify that figure in the current listing if it affects your decision.
What should you verify before ordering?
For kits, check compatibility with the exact sprayer model and tank size. For complete sprayers, confirm towing or mounting format and review the seller’s current included-components information. The supplied product details do not establish dimensions, towing limits, or compatibility beyond the claims stated above.
