Best Sprayers for Lawn Mowers for Spot and Wide-Area Coverage
The best sprayer for a lawn mower depends on whether you need broad coverage, targeted application, or a compact option. The NorthStar 31-gallon model is best for larger areas, while the 21-gallon NorthStar offers a smaller tow-behind format. The Chapin is an ATV/UTV-style option to consider if its mounting works with your equipment. For small jobs, the CRAFTSMAN wand and PetraTools pump sprayer offer handheld alternatives.
| Product | Best suited for | Format |
|---|---|---|
| NorthStar 31-Gallon | Large areas and boom spraying | Tow-behind boom/spot |
| NorthStar 21-Gallon | Smaller-capacity tow-behind use | Tow-behind boom/spot |
| CHAPIN 8-Gallon | ATV/UTV-based spraying | 12V spot sprayer |
| CRAFTSMAN Battery Wand | Ready-to-use chemical bottles | Battery wand |
| PetraTools HD101 | Small garden and spot tasks | Hand pump |
NorthStar 31-Gallon Tow-Behind Sprayer
Best for: Owners maintaining larger lawns who want a tow-behind sprayer with both boom and spot-spraying capability. Its 31-gallon tank and 120-inch overall boom width are designed for covering ground more quickly than a handheld sprayer.
The listing specifies a 2.2 GPM, 70 PSI pump with a continuous-duty rating. The boom has an 80-inch effective spray width, spring-loaded breakaway arms, and separate left and right nozzle controls. A UV-resistant tank, gallon markers, 7.5-inch fill lid, steel cart, and 12-inch pneumatic wheels are also listed.
Why it stands out: It combines a large tank with a wide boom and independent nozzle control, which can help tailor coverage near edges or obstacles. Limitation: Its 31-gallon tank and tow-behind cart call for adequate storage and a suitable towing setup.
CHAPIN 8-Gallon ATV/UTV Sprayer
Best for: Buyers seeking an 8-gallon, 12V sprayer described for ATV and UTV use. The listed 15-foot hose offers reach for spot spraying, while the powered format avoids relying on a hand-pump tank.
Why it was selected: It provides a mid-capacity alternative between a small handheld unit and the larger NorthStar tow-behind options. Limitation: The product is listed as an ATV/UTV sprayer, so check its mounting and placement requirements before using it with a lawn mower.
NorthStar 21-Gallon Tow-Behind Sprayer
Best for: Buyers who want a tow-behind boom/spot sprayer but prefer a 21-gallon capacity to the 31-gallon model. The product name lists a 2.2 GPM, 12V pump and 70 PSI rating.
Why it was selected: Its capacity and tow-behind format make it a useful comparison for lawn-mower owners choosing between two tank sizes. Limitation: The supplied product details do not specify boom width or other construction features, so confirm those details in the current listing before purchase.
CRAFTSMAN Battery-Powered Sprayer Wand
Best for: Small, targeted lawn and garden applications using ready-to-use chemicals. The wand attaches to compatible 38mm refill bottles, needs no pumping, and includes four AA batteries.
Why it was selected: It offers a compact alternative when a mower-mounted or tow-behind tank would be unnecessary. Limitation: It uses ready-to-use bottles rather than a large refillable tank, so it is better for spot jobs than broad lawn coverage.
PetraTools HD101 One-Gallon Pump Sprayer
Best for: DIYers who need a portable sprayer for small areas, garden treatments, or targeted applications. It has a one-gallon translucent tank with markings, a 52-inch hose, a 16-inch wand, and two nozzles.
The listing also describes a funnel-shaped opening, ergonomic handle, and pressure-release safety valve. It is specified for versatile liquids such as fertilizers, mulch glue, and pesticides.
Why it was selected: Its hose and wand provide reach without requiring a mower-mounted setup. Limitation: The one-gallon capacity is small for treating a large lawn in a single fill.
Buying Guide: How To Choose A Lawn-Mower Sprayer
Should you choose a tow-behind or handheld sprayer?
Choose a tow-behind unit when you need to treat a larger area and have equipment that can safely tow it. A handheld wand or pump sprayer is more appropriate for isolated weeds, garden beds, or small patches. These formats serve different jobs, so compare intended coverage before comparing tank size alone.
How much tank capacity do you need?
A larger tank can reduce refill interruptions, but it also means more liquid to handle and more storage space. The 31-gallon NorthStar emphasizes capacity, while the 21-gallon model is the smaller tow-behind choice. The one-gallon PetraTools and bottle-attached CRAFTSMAN wand are intended for more localized work.
What should you check before mounting or towing?
Confirm that the sprayer’s attachment method, dimensions, and loaded weight suit your mower or other vehicle. The Chapin listing describes ATV/UTV use, so verify mower mounting suitability rather than assuming it will fit. For any powered sprayer, review the product instructions and electrical requirements before use.
Do boom width and nozzle controls matter?
A boom can apply spray across a broader path, which is useful for open areas. Independent nozzle controls, as listed for the 31-gallon NorthStar, allow the operator to manage left and right coverage separately. Spot sprayers instead direct liquid through a hose or wand and can be more practical near obstacles.
Frequently Asked Questions
Can I use a lawn-mower sprayer for spot treatment?
Yes. A spot-spraying unit or handheld wand can target specific areas. Check the sprayer instructions and the chemical label for permitted use.
Is a larger tank always better?
No. Larger capacity can reduce refills for broad coverage, but a smaller tank may be easier to store and more suitable for occasional jobs.
Is the Chapin sprayer confirmed to fit a lawn mower?
The supplied product name identifies it as an ATV/UTV sprayer. Confirm its mounting and placement requirements before using it with a mower.
Which option is suited to the smallest jobs?
The CRAFTSMAN wand uses ready-to-use chemical bottles, while the PetraTools has a one-gallon tank. Either may suit targeted work; choose based on the container format and features you need.
