Why the Westinghouse WMow18 40V Is Worth Considering (Quick Verdict)
Because it delivers gas-like cutting power without the maintenance, the Westinghouse WMow18 40V is worth considering if you want a compact, efficient cordless push mower. You’ll get brushless torque up to 3,100 RPM for clean, edge-to-edge cuts on an 18-inch deck, plus six-height adjustments for varied turf. Runtime suits small to medium yards; two batteries extend work without fuel hassles. You’ll notice quieter operation than gas units and easier handling at roughly 33–36 pounds. The design favors compact storage and quick swaps within the 20V ecosystem, making this a practical, low-maintenance choice. It’s also a good fit for homeowners who enjoy maintaining their outdoor spaces and prefer self-propelled mowers for convenience.
What the WMow18 40V Includes: Batteries, Charger, and Assembly Details
While the WMow18 40V is compact, it comes ready to run: Westinghouse includes two 20V 4.0 Ah batteries (for a 40V setup) and a 4A dual charger, so you can charge both packs simultaneously and swap batteries quickly to extend runtime. Included accessories are minimal but practical: the 13-gallon collection bag, mulching plug, and basic tool kit for assembly. You’ll perform straightforward assembly—attach handle halves, secure grass bag, and install batteries—using clear instructions. Assembly tips: torque bolts snugly, align handle clamps before tightening, and charge both batteries fully before first use to balance cells and maximize lifespan. This mower is ideal for homeowners who value battery-powered mowers and enjoy maintaining their outdoor spaces.
Real-World Performance: Cutting Power, Runtime, and Handling on Small–Medium Yards
With the batteries charged and assembly finished, you’ll judge the WMow18 40V by how it handles real lawn conditions. You’ll find its brushless motor delivers steady torque at up to 3,100 RPM, slicing medium-thick and tall grass cleanly across the 18-inch deck. Runtime hits about 30–35 minutes with two 4.0 Ah packs—enough for typical small–medium yards but plan swaps for denser turf. Noise levels stay noticeably lower than gas equivalents, easing neighborhood use. At roughly 33–36 lb, maneuverability is strong; slope handling on mild inclines is competent, though you’ll exercise caution on steeper terrain. The mower fits well into a lineup of tools for homeowners who enjoy their outdoor spaces and complements other electric options like battery-powered trimmers and blowers for outdoor maintenance.
Adjustability and Features That Matter: Deck, Height Settings, Mulch vs. Bagging
When you adjust the WMow18’s 18-inch deck, you’ll get six precise height positions—about 1 to 3 inches—to match turf conditions and seasonal needs. You’ll change heights with a single lever that indexes securely; adjustments feel positive and repeatable. Deck durability is solid for residential use, resisting dents from routine encounters while keeping alignment for edge-to-edge cutting. Choose the mulch plug to return nutrients or attach the 13-gallon dual-handled bag for collection; switching is tool-free and quick. Expect lower blade noise than gas units thanks to the brushless motor, improving user comfort during extended runs. This mower pairs well with other essential gear for homeowners who enjoy outdoor spaces at home.
Who Should Buy This Mower and How It Compares to Similar 18 Battery Mowers
If you value precise height control, easy mulching or bagging swaps, and quieter, gas-free performance for small to medium yards, the WMow18 is a strong candidate. You’ll get an 18″ deck, six-position adjustments, and dual 4.0 Ah batteries that deliver up to ~35 minutes runtime—suitable for up to a half-acre under typical conditions. Compared to similar 18″ battery mowers, it balances torque and weight well; battery lifespan is typical for lithium 20V cells when maintained. In noise comparison tests it runs noticeably quieter than gas units and on par with other brushless battery models, with competitive build and warranty. Owners should also keep a basic set of maintenance tools and replacement blades on hand to ensure optimal long-term performance.
Some Questions Answered
Are Additional Westinghouse Batteries Sold Separately Compatible With This Mower?
Yes — additional Westinghouse batteries sold separately are compatible with this mower. You’ll use the W20 Series 20V batteries (two make the 40V system); many DeWalt 20V MAX/XR cells also work. For charger options, you can use the included 4A dual charger or other W20-compatible chargers to charge both batteries. You’ll get consistent Battery compatibility and flexible Charger options for longer runtime or replacing worn cells.
Can This Mower Be Stored Vertically to Save Garage Space?
Yes — you can store it vertically for space savings. You’ll use upright parking with the handle folded per assembly instructions, ensuring the battery is removed and the mower is on a stable surface. Vertical storage reduces footprint but avoid leaning on the deck or blade; use manufacturer-recommended support points. Keep it dry, charged batteries stored separately, and secure against tipping. Follow manual guidance for safe vertical storage and upright parking.
Is Blade Sharpening or Replacement Covered Under Warranty?
No — blade sharpening or replacement isn’t typically covered under the 2-year limited warranty. You’re responsible for routine blade maintenance and wear-related service; warranty limits cover defects in materials and workmanship, not normal wear or damage from misuse. Keep records and photos if you claim a defect, follow maintenance guidance, and contact Westinghouse customer service for warranty evaluation. You can replace or sharpen blades locally or via authorized service.
How Loud Is the Mower in Decibels During Operation?
You’ll hear roughly 70–75 dB(A) at the operator position during cutting. Those noise levels mean the mower runs quieter than a typical gas mower (around 85–95 dB) but louder than most battery-powered string trimmers. For a sound comparison, it’s similar to a dishwasher or vacuum cleaner. You shouldn’t need hearing protection for short jobs, but use it for extended periods or close bystanders to reduce fatigue and noise exposure.
Are Replacement Grass Bags and Mulch Plugs Available From Westinghouse?
Yes — you can get replacement bags and mulch adapters from Westinghouse and compatible third parties. You’ll order the 13-gallon double-handled replacement bag or OEM mulch plug/adapter designed for the 18-inch deck; DeWalt-compatible 20V platform accessories also fit. Check part numbers with Westinghouse support or retailers to confirm fit. Keep your model number handy, and you’ll replace worn bags or swap in a mulch adapter quickly for mulching or bagging.
