25-Gal Diamond Spot Sprayer | 4.0 GPM 12V Pump (45 PSI)

The AgSpray 25-Gallon Diamond Spot Sprayer is a vehicle-mounted liquid applicator designed for landowners, farmers, and commercial groundskeepers. Built to handle herbicides, pesticides, and fertilizers, it mounts directly to ATV racks, UTV beds, or trailers to manage fence lines, food plots, pastures, and broad property perimeters.

At the core of the system is a 12V diaphragm pump pushing 4.0 GPM at 45 PSI, monitored by a 2.5-inch liquid-filled pressure gauge. This output pairs with a Pro spray handgun featuring an adjustable nozzle, which achieves a 38-foot horizontal reach and a 27-foot vertical throw. Combined with 15 feet of 3/8-inch hose, it lets you target distant weeds, high foliage, and tight property borders without having to maneuver your vehicle right next to every spot.

The physical build focuses on field convenience. Its low-profile polyethylene tank resists both UV exposure and chemical corrosion, keeping the center of gravity stable on rough terrain. A 5-inch fill lid includes a lanyard so it cannot get lost in the field, while molded gallon markers and an accessible drain port simplify measuring mixes and rinsing out the tank after use.

As a dedicated spot sprayer, this unit uses a single wand rather than a wide-area boom, so covering massive open fields will take more passes. Operating the pump also requires an available 12-volt power source on your utility vehicle or trailer.

Verdict: The AgSpray 25-Gallon Spot Sprayer is a dependable choice for property owners who need strong pump pressure and extended spray reach for targeted weed and pest control. If you need to treat fence lines, pastures, and landscaped borders from an ATV or UTV, this setup provides solid capability right out of the box.
