Best Sprayer For Lawn Mower: Tow-Behind and Spot Options

#1 · Best Overall

1. Master Mfg 12 Gallon Pull-Behind

• Weight: 32 lb
• Material Type: Metal, Plastic
• Material: Metal, Plastic

Best for: Zero-turn mower broadcast spraying.

Why it ranks #1: Its listing specifically names commercial and zero-turn mower use; the 12-gallon tank, 7-foot swath, and 15-foot hose suit broadcast and spot work.

An 84-inch, or seven-foot, swath lets this 12-gallon Master Mfg pull-behind sprayer cover ground from a single-nozzle boom. Its listed setup suits commercial or zero-turn mowers, and the unit can also be hitched behind an ATV, giving buyers more than one supported towing option.

The 1.1 GPM 12V Everflo on-demand pump supplies powered spraying, while the single-nozzle boom covers seven feet when operated at 30 PSI and six miles per hour. A 15-foot hose with a trigger-lock gun extends the workflow beyond broadcast passes for spot applications. Never-flat, 10-inch foamed tires are specified for rugged terrain, and the rear drain port supports emptying after use. The sprayer is approved for Round-Up and other agricultural-brand herbicides and insecticides.

Skip it if you want a 15-gallon tank and 2.2 GPM pump; the Master Mfg 15-Gallon ATV Boom Sprayer lists those specifications.

This fits zero-turn or commercial mower owners seeking a compact pull-behind unit for broadcast and spot applications. The stated seven-foot coverage depends on operating at 30 PSI and six miles per hour, so account for that condition.

#2 · Highest Capacity

2. Master Mfg 25 Gallon Trailer

• Material Type: Alloy Steel
• Material: Alloy Steel

Best for: Large-volume mower trailer spraying.

Why it ranks #2: The 25-gallon trailer is listed for zero-turn mowers and provides a 7-foot broadcast width plus spot spraying up to 25 feet vertically.

A 25-gallon tank and adjustable broadcast coverage up to seven feet make this Master Mfg trailer sprayer a substantial option for mower-towed lawn work. Its dual deflector nozzles cover broad passes, while the adjustable gun supports spot spraying as far as 25 feet vertically and 30 feet horizontally.

The 2.2 GPM 12V Everflo diaphragm pump and pressure-regulating system provide powered application with pressure control. For broadcast work, the adjustable boom reaches up to a seven-foot spray width; for targeted areas, the gun reaches up to 25 feet vertically and 30 feet horizontally. It can be hitched to zero-turn mowers, ATVs, and UTVs, supporting several towing setups. The listed use case is small to medium lawns, food plots, and waterways across one to two acres.

Skip it if you need a sprayer that can be carried by hand; the Roundup 190260 is a 2-gallon handheld model for targeted tasks.

This is a fit for owners of zero-turn mowers, ATVs, or UTVs treating small to medium lawns, food plots, or waterways. Its trailer format and 25-gallon tank suit towing, not handheld spot work.

#3 · Lawn Tractor Mount

3. Chapin 97154 15-Gallon Sprayer

• Weight: 17 lb
• Material Type: Plastic
• Material: Plastic

Best for: Visible-fill ATV lawn spraying.

Why it ranks #3: This 15-gallon ATV/UTV spot sprayer is also listed as mounting to a lawn tractor, with a 1.0 GPM pump and 15-foot hose.

A translucent 15-gallon tank lets you see the fill level while spraying from an ATV, UTV, or lawn tractor. Chapin pairs it with a 12V pump and 15-foot reinforced hose, making this a powered spot-sprayer option for weed control and fertilizing without manual pumping.

The 1.0 GPM diaphragm pump provides powered application, while the 15-foot reinforced hose gives the user reach away from the mounted tank. Double filtration—an in-tank filter and a shut-off filter—is intended to help prevent clogs and reduce downtime during work. The chemical-resistant poly tank has a six-inch opening for filling, mixing, and cleaning, and its translucent construction makes the fill level visible. The listing specifies mounting on an ATV, UTV, or lawn tractor.

Skip it if you need a broadcast boom with a specified swath; the Master Mfg 15-Gallon ATV Boom Sprayer lists a seven-foot swath.

Pick this Chapin for ATV, UTV, or lawn-tractor users who value a visible tank level, powered spot spraying, and filtration. Its 1.0 GPM pump and spot-sprayer format are the relevant fit boundaries.

#4 · Wide Boom Coverage

4. Master Mfg 15-Gallon Boom Sprayer

• Weight: 31 lb
• Material Type: Plastic
• Material: Plastic

Best for: ATV broadcast and spot coverage.

Why it ranks #4: Its 7-foot steel boom and 2.2 GPM pump support broad application, while the adjustable gun reaches up to 25 feet vertically and 30 feet horizontally.

A 7-foot all-steel broadcast boom gives this 15-gallon Master Mfg sprayer a way to cover a wide strip from an ATV or UTV, while its adjustable brackets help maintain spray height as terrain changes. It also includes an adjustable gun for targeted applications beyond the boom’s pass.

The 2.2 GPM, 12V Everflo diaphragm pump works with a pressure gauge, regulator, and boom shut-off, giving the operator controls for managing broadcast application. For edges or isolated areas, the adjustable spray gun reaches up to 25 feet vertically and 30 feet horizontally. The 15-gallon tank supports lawn, food-plot, or waterway work, while the wire harness and included gun clips support setup and stowing the sprayer’s hand tool between uses.

Skip it if you need a pull-behind unit with a larger tank; the Master Mfg 25 Gallon Deluxe offers 25 gallons for mower towing.

This suits ATV or UTV owners treating small to medium lawns, food plots, and waterways who want both broadcast and spot spraying. Check that the 15-gallon tank and vehicle-mounted format fit the area and equipment you use.

#5

5. NorthStar 31-Gallon Tow-Behind

• Weight: 54 lb
• Material Type: Metal, Plastic
• Material: Metal, Plastic

Best for: Large-capacity tow-behind spraying.

Why it ranks #5: The 31-gallon tow-behind format and boom/spot design suit larger spraying jobs, though the supplied facts do not confirm mower compatibility.

A 31-gallon tank gives the NorthStar tow-behind sprayer ample listed capacity for buyers who want a trailer-style unit rather than a handheld lawn sprayer. Its 12V, 2.2 GPM system and boom/spot format identify it as a powered option for pest-control applications behind suitable equipment.

The tow-behind configuration lets the sprayer travel with the towing vehicle, while the 31-gallon capacity provides a larger tank format for pest-control work. Its 12V pump is rated at 2.2 GPM, and the boom/spot designation indicates both broadcast and targeted spraying modes. The listing includes a hose and trigger spray gun, so the hand-operated tool is part of the package. At 54 pounds and 42 by 28.5 inches, its size and weight matter when planning handling and storage.

Skip it if you need a listed boom width or spray-gun reach before choosing; the Master Mfg 15-Gallon ATV sprayer specifies both.

Choose this NorthStar for pest-control jobs where a 31-gallon tow-behind format and included trigger gun suit your workflow. Its 54-pound weight and 42-by-28.5-inch dimensions make handling and storage considerations for your setup.

6. Petra HD4000 Backpack Sprayer

• Material Type: High Density Polyethylene (HDPE)
• Material: High Density Polyethylene (HDPE)

Best for: Long-runtime backpack spraying.

Why it ranks #6: Its 4-gallon battery-powered format is portable for spot treatment, and the listed battery pumps more than 200 gallons per charge.

A 12V 8Ah battery powers this four-gallon PetraTools backpack sprayer for a listed six to eight hours, enabling extended spraying without manual pumping. Its package includes six nozzles, giving lawn and garden users multiple nozzle choices while carrying the tank on their back.

PetraTools states that the battery can pump more than 200 gallons per charge, a useful capacity reference for longer weed-control, watering, or pest-control sessions. The six included nozzles let users select among different spray options for varying tasks, while the battery charger and measuring cup support charging and preparation. Its backpack form carries the four-gallon tank with the operator rather than requiring a mower hitch, so it suits portable work but requires carrying the filled sprayer.

Skip it if you want to spray while seated on a mower; the Master Mfg 12-Gallon Pull-Behind Sprayer is made for mower towing.

This is for users who need portable, extended spraying around lawn and garden areas and can carry a four-gallon backpack tank. Its battery runtime and included nozzle selection suit longer sessions, not mower-mounted broadcast coverage.

#7

7. Scotts 2-Gallon Power Wand

• Weight: 7.8 lb
• Material Type: Polypropylene (PP)
• Material: Polypropylene (PP)

Best for: Battery-powered handheld lawn care.

Why it ranks #7: The battery-powered 2-gallon sprayer runs for up to two hours or sprays up to 25 gallons per charge, but it is not a mower-mounted unit.

A rechargeable 3.6V lithium-ion battery eliminates manual pumping and sprays up to 25 gallons or two hours per charge. The Scotts two-gallon Power Wand also reaches up to 20 feet, giving lawn and garden users powered application without carrying a mower-mounted tank across each treatment area.

The battery-powered wand reduces the pumping work associated with manual sprayers, while its stated runtime supports extended lawn, weed-control, and home applications. Its universal 38mm adapter cap lets the Power Wand attach to common ready-to-use bottles, adding a second way to use the wand; the bottle is not included. A comfort harness supports carrying the sprayer, and the included charger, nozzle, and adapter provide the listed accessories. Clean the sprayer after use, as directed in its safety information.

Skip it if you need a large mower-towed tank for broadcast coverage; the Master Mfg 25 Gallon Deluxe pulls behind zero-turn mowers and has a seven-foot swath.

This suits users who want cordless handheld lawn or garden spraying with reduced pumping effort and a wand that can use common 38mm bottles. The two-gallon tank and two-hour maximum runtime define its scale.

#8

8. Husqvarna 2-Gallon Battery Sprayer

• Weight: 6 lb
• Material Type: Rubber, Stainless Steel
• Material: Rubber, Stainless Steel

Best for: Chemical-handling handheld spraying.

Why it ranks #8: A battery pump, 25-inch wand, and 50-inch reinforced hose make it useful for portable spot applications, not continuous mower-towed coverage.

A pressure-release valve helps prevent chemicals from reaching the user before the Husqvarna tank is opened, a relevant safety feature for its two-gallon battery sprayer. The powered pump avoids manual pumping, while the package includes a stainless-steel wand, reinforced hoses, and three nozzles.

The 7.2V battery powers the pump, replacing manual operation for portable lawn, cleaning, or sanitizing work. A commercial-grade shut-off with a comfortable grip is specified for chemical resistance, and the in-line filter is easy to clean to support maintenance. The 25-inch stainless-steel wand and supplied nozzle kit support application choices, while vertical wand storage helps keep the tool organized. Its tear-shaped tank is described as having a low center of gravity for stability during use.

Skip it if you want a mower-pulled broadcast boom for larger areas; the Master Mfg 25 Gallon Deluxe offers a seven-foot swath behind zero-turn mowers.

This suits buyers seeking portable battery spraying for lawn care, commercial cleaning, or sanitizing, especially when the pressure-release valve and easy-clean filter matter. Its two-gallon handheld format is not a trailer broadcast setup.

#9

9. VIVOSUN 2-Gallon Battery Sprayer

Best for: Two-mode battery garden spraying.

Why it ranks #9: Its 2-gallon tank and up to three hours of battery runtime offer portable lawn and garden spraying, but no mower hitch or boom is listed.

Switchable low- and high-pressure modes let the VIVOSUN two-gallon battery sprayer move between delicate plant spraying and tougher outdoor cleaning. Press-on operation replaces manual pumping, and the built-in 2200mAh battery is listed for up to three hours of runtime per charge.

The one-press continuous-spray operation reduces the repeated effort of manual pumping, while the two pressure modes let users select an approach for different listed tasks. Up to three hours of battery runtime supports sessions without continuous hand pumping, and the indicator keeps power status in view while working. Its two-gallon capacity and lawn-and-garden watering designation suit portable jobs rather than large-area mower towing. The supplied facts also describe dual waterproof protection for outdoor use.

Skip it if you need more tank capacity for mower-towed coverage; the Master Mfg 12-Gallon Pull-Behind Sprayer holds 12 gallons and covers seven feet.

This fits garden and lawn users who want portable, battery-powered spraying with selectable pressure. Its two-gallon capacity and three-hour maximum runtime make it a smaller-scale option than a mower-towed broadcast unit.

#10

10. Roundup 2-Gallon Lawn Sprayer

• Weight: 3.9 lb
• Material Type: Poly
• Material: Poly

Best for: Small-area manual spot spraying.

Why it ranks #10: This manual 2-gallon sprayer includes three nozzles for garden and weed-control tasks, but its handheld format does not match mower-based spraying.

Three included nozzles—a poly adjustable, high-volume flat fan, and foaming nozzle—give the Roundup two-gallon sprayer options for varied home and garden tasks. Its manual pressurize-and-spray operation makes it a compact choice for targeted weed or insect control, as well as cleaning decks and siding.

The two-gallon poly tank keeps this unit in a portable handheld format for smaller jobs rather than mower-towed coverage. A comfort grip and lockable shut-off support continued spraying without holding the trigger open, while the wand clips into place when it is not being used. The pressure-release cap directs vapors and liquids down and away when opened. One-step assembly and three nozzle types offer a straightforward setup for spot applications, though operation still requires manual pressurizing.

Skip it if you want battery-powered spraying without manual pumping; the Scotts 2 Gallon Lithium-Ion Power Wand Sprayer runs on a rechargeable battery.

Choose this Roundup for small, targeted home and garden jobs where a two-gallon handheld tank and interchangeable nozzles are useful. It is not a mower-pulled broadcast sprayer, and its manual operation involves pressurizing before use.
