How to Choose the Best ATV Sprayer

Picking the best ATV sprayer comes down to five things. Tank capacity, application rate, boom versus boomless, pump output, and how it mounts. Brands like Fimco, NorthStar, Chapin, and Master Mfg make most of the ATV and UTV sprayers out there. You’ll find them at Tractor Supply and Northern Tool. Here’s how I sort each one.

What Size Tank Do You Need? (Acres Per Tankful)

Match your tank capacity to your acreage. The math is easy. Take your tank gallons and divide by your gallons per acre (GPA) rate. That gives acres per fill. One ATV tank covers roughly 1 to 5 acres. At 5 GPA, a 15-gallon tank does about 3 acres before a refill. A 25-gallon tank is the practical ATV ceiling, because a full one tops 200 pounds. Add a rider, and a small quad turns tippy. For most acreage under 5 acres, 15 gallons is the sweet spot. For jobs under an acre, a battery backpack sprayer may be all you need.

Boom vs Boomless vs Spot Sprayer

A boom sprayer gives the most even, accurate coverage and drifts less. The nozzles sit low and point straight down. The downside: the arms catch on posts, brush, and trees. A boomless nozzle setup uses one or two wide-angle tips to throw a broad swath. Nothing sticks out, so it clears obstacles and needs less upkeep. The trade-off is bigger droplets and slightly patchier coverage. A spot sprayer with a handheld wand is your fence-line and tree tool, built for targeted shots, not broadcast passes. For a few weeds by the barn, even a small handheld sprayer works. Many rigs, like the Chapin models, include a wand so you get both.

Pump Flow (GPM) and Pressure (PSI)

A 12V diaphragm pump is the standard, and adjustable pressure matters more than flow. GPM (gallons per minute) sets how fast you cover ground and feed nozzles. PSI (pounds per square inch) sets spray range and droplet size. Most 12V pumps run 40 to 60 PSI, and the biggest top out near 5 GPM at 60 PSI. For a single boom or spot wand, 1 to 2 GPM is plenty. Run a bigger pump on few nozzles, and add a pressure regulator so it stops cycling. Brands like Everflo sell solid replacement pumps.

Chemical Compatibility (Herbicide, Fertilizer, Pesticide)

Most ATV sprayers handle common farm chemicals just fine. That covers herbicide like glyphosate, fungicides, insecticides, and liquid fertilizer such as 28-0-0 or a foliar feed. The catch is petroleum-based products. Oil-based and some deicing liquids can swell standard seals. For those, you want a pump with Viton or Buna (nitrile) parts. Check the pump’s seal material against your chemical label before you buy. A sprayer that fits your weed control plan should also handle your fertilizer runs. For small garden beds, a hose-end sprayer meters liquid feed without a tank at all.

Mounting, Fit, and Build Quality

Check your rack capacity before anything else. A full 15-gallon tank runs 125-plus pounds. Make sure your ATV rack handles that load, whether you run a Can-Am, Honda, or John Deere Gator. For mounting style, EZ Mount brackets bolt on fast, while strap-down units move quicker between machines. Favor a UV-stabilized poly tank so sun doesn’t make it brittle after a season outside. Good hose clamps and screen filtration keep grit out of the pump and nozzles. Cheap hoses and clamps are the number-one failure point folks gripe about.

The 7 Best ATV Sprayers: Reviewed and Ranked

Here are the seven rigs I’d actually bolt to a rack, sorted by tank size and spray type. All of them handle herbicide, and most double for fertilizer. So match the tank to your acres and the spray type to your ground.

1. Chapin 97154 15-Gallon Spot Sprayer

Chapin has built sprayers in Batavia, New York since 1884. The 97154 is a 15-gallon spot rig, and my top pick for most farms. It works best on fence lines, food plots, and acreage under 5 acres. It’s the first sprayer I’d hang on my own ATV. Side-by-side owners see a clean 10-foot reach from the seat.

Specs:

• 15-gal chemical-resistant poly tank
• 12V diaphragm pump, 1 GPM
• Nitrile seals resist chemicals
• 15-ft hose, 18-inch wand

2. Master Mfg 15-Gallon UTV & ATV Spot Sprayer

Master Mfg, a Valley Industries brand, keeps this one simple. You fill it and spray, because the pump needs no priming. It’s a 15-gallon spot sprayer built for weeds on fence lines and isolated patches. That fill-and-go setup skips the hose-dragging I put up with on my own place.

Specs:

• 15-gal UV-resistant poly tank
• Everflo 1 GPM diaphragm pump
• 15-ft rubber hose included
• Molded drain port

3. Chapin 97084 8-Gallon Spot Sprayer

This is the compact Chapin, and my pick when acres are tight. At 8 gallons and 9 pounds, it drops onto a garden cart or small ATV without weighing things down. Then an inline switch lets you spray from the seat. Reviewers with small lots like how light it is to move on and off a cart.

Specs:

• 8-gal chemical-resistant poly tank
• 12V diaphragm pump, 1 GPM
• 60 PSI max pressure
• 20-inch wand, 15-ft hose

4. Ironton 8-Gallon ATV Spot Sprayer

Ironton is Northern Tool’s value brand, and this 8-gallon rig punches above its price. The standout is the pump, because it pairs a Santoprene diaphragm with Viton valves that shrug off herbicide. So it’s approved for Roundup and most liquid pesticides. Budget buyers give it high marks for value, with hundreds of reviews to back that up.

Specs:

• 8-gal UV-resistant poly tank
• 1 GPM chemical-resistant pump
• 11-ft braided clear hose
• Easy bottom drain valve

5. Master Mfg 15-Gallon ATV Broadcast Sprayer

Step up to a real boom with this Master Mfg unit. The all-steel 7-foot boom lays down an even swath across lawns, food plots, and waterways. Then a pressure regulator and three nozzles let you dial in coverage for herbicide or a fertilizer program. Coming off a sagging plastic boom, those steel arms are the real upgrade.

Specs:

• 15-gal translucent poly tank
• Everflo 2.2 GPM, 70 PSI
• All-steel adjustable-height boom
• 25-ft hose, three nozzles

6. Chapin 97214 25-Gallon Deluxe 2-Nozzle Boom

Chapin’s deluxe boom is the flexible one. The 2-nozzle #6428 boom throws a 7-foot pattern, then pops off so you can switch to the 19-inch wand for fence lines. Its 2.5 GPM pump self-primes, and three filters guard against clogs. For mixed jobs, that removable boom is the reason to reach for it.

Specs:

• 25-gal rust-resistant poly tank
• 2.5 GPM 12V diaphragm pump
• 2-nozzle #6428 steel boom
• 3-stage filtration, 15-ft hose

7. NorthStar 16-Gallon Boomless Sprayer

When pastures get standard, this is my pick. NorthStar, Northern Tool’s premium brand, skips the boom arms entirely. One deluxe gun throws a 14-foot broadcast cone, then a selector valve flips to spot spray. On real acreage, buyers clock through an acre fast with that wide 14-foot cone.

Specs:

• 16-gal UV-resistant polymer tank
• NSQ 2.2 GPM, 70 PSI
• Viton valves, Santoprene diaphragm
• Pressure regulator, in-line fuse

How to Make an ATV Sprayer Last

Most ATV sprayer complaints trace back to two things: freeze damage and leaks. Both are preventable. A little care after each run keeps the pump and hoses alive for years, not one season.

Flush it after every use. Run clean water through the tank, hose, and nozzles when you finish. Do this before you switch chemicals, so herbicide residue never taints your fertilizer pass. Old chemical gunk clogs nozzles and eats seals.

Winterize the pump. Before the first hard freeze, drain the tank fully. Then run RV antifreeze through the pump until it shows at the nozzle. Water left inside a 12V diaphragm pump freezes, expands, and cracks the housing. This one step stops the most common pump failure.

Chase down leaks early. The drain plug is the number-one leak point on nearly every model. Wrap the threads with PTFE tape and snug it with a wrench, not just your hand. Swap cheap hose clamps for better ones while you’re at it.

Store it inside. Keep the sprayer out of direct sun and hard heat. UV and temperatures above 105°F make hoses and poly parts brittle fast. A shed or garage wall doubles the life of the plastic.
