Master Mfg 15-Gallon UTV & ATV Spot Sprayer

Best for bigger weed patches and longer fence lines. Caution: higher PSI and capacity demand a sturdier mounting and more careful weight distribution on uneven terrain.
Chapin 97154 Tank Sprayer, 15‑Gallon

This Chapin model emphasizes coverage with a 15-gallon poly tank and 15-foot reinforced hose for extended reach. It uses a 12V diaphragm pump delivering a steady 1.0 GPM. It’s well suited for larger lawns or fields where balanced capacity and spray consistency matter. Best for: homeowners tackling sizable lawns without frequent refills. Limitation: without an included hose reel or extra mounting hardware, setup may require additional accessories.

Designed for mobility, the 8-gallon Chapin focuses on compact spaces and quick spray jobs. With a 12V hookup and a 1 GPM diaphragm pump, it provides reliable flow for spot spraying and spot fertilizing.

Chapin 97254 25-Gallon Mounted ATV/UTV Spot Sprayer

The 25-gallon mounted Sprayer is ideal for ATV/UTV setups that require a sturdy, built-in solution for bulk spray tasks. It features a wide-mouth 6-inch opening, a chemical-resistant poly tank, and a mounting system for quick deployment. Best for: frequent, larger-area jobs where mounting stability is essential. Limitation: mounting hardware compatibility may vary by vehicle model.
Buying Guide: How to Choose the Right Sprayer
What capacity do you actually need?
Capacity determines how often you refill. For small yards or fence lines, 8–15 gallons may suffice. For mid-size lawns or fields, 15–25 gallons balances reach with weight. For larger properties, 25–40 gallons reduces downtime but adds weight and mounting considerations.
What pump and flow rate matter?
A diaphragm pump with 1.0–2.2 GPM is common. Higher GPM speeds coverage on large areas but can feel heavier and require sturdier mounting. A reliable 12V pump is standard for ATV/UTV sprayers and works with most rechargeable systems.
How important is spray reach?
Spray reach depends on the nozzle, gun, and pressure. A spray gun capable of 18–30 feet horizontal reach is versatile for weed lines and fence rows. For tall targets like trees or hedges, look for models with adjustable nozzles and higher vertical reach.
Are mounting and vehicle compatibility concerns important?
Ensure your vehicle’s bed or hitch can support the sprayer’s weight when full. Check mounting hardware compatibility with your ATV/UTV model, and verify hose length to avoid drag or damage during operation.
What maintenance benefits should you expect?
In-tank filters and shut-off filters reduce clogs. Chemically resistant tanks and hoses extend life against fertilizers and pesticides. Consider models with simple access for cleaning and maintenance between uses.
What should you avoid?
A model with a small tank and limited hose length can lead to constant refills. Extremely high PSI without adequate mounting may cause stability issues. Avoid mismatched pumps and hoses that reduce spray consistency or cause leaks.
Quick buying tips

- Prefer a diaphragm pump with proven reliability and parts availability.
- Match spray gun reach to typical target areas (fences, lawns, trees).
