Power & Performance
The WORX 40V battery platform delivers solid power for its intended use case , maintaining a healthy, regularly-mowed small lawn. The rotary cutting system handles typical residential grass types like fescue, bluegrass, and St.
Augustine at comfortable mowing heights with consistent results. It's not engineered for reclaiming neglected or heavily overgrown yards, but for a kept-up small lawn it performs reliably and quietly.
Cutting System
The 16-inch polymer rotary deck keeps the mower light and rust-free, though it trades some long-term durability for that weight savings. Seven cutting height positions spanning 1.5 to 4.0 inches are controlled via a single lever, making height changes fast between mowing sessions.
The 2-in-1 design supports mulching and rear bagging discharge options, giving users flexibility based on grass clipping preference.
Drive & Handling
This is a manual push mower, meaning all forward propulsion comes from the user , a non-issue at 35.3 lbs on flat terrain. The lightweight build and compact 16-inch deck make it genuinely easy to navigate around flowerbeds, trees, and tight corners.
The foldable handle simplifies storage and transport significantly, and customers report it cuts right to the edge for clean lawn lines.
Battery / Fuel
Two 40V 4.0Ah batteries are included, which is a meaningful value-add , most competitors include only one. Each battery provides a single runtime session, and having two allows you to swap mid-mow if needed for larger portions of the rated 5,445 sq ft coverage area.
No oil changes, spark plugs, air filters, or fuel stabilizers are ever needed; maintenance is limited to blade care and keeping the deck clean.

FAQ
How long do the batteries last on the WORX 40V lawn mower?
Runtime varies based on grass thickness, cutting height, and terrain, but each 4.0Ah battery is generally sufficient for a portion of the rated 5,445 sq ft coverage area. Since two batteries are included, you can swap mid-mow and keep going without waiting for a recharge.
For most small yards under 3,000 sq ft, a single battery charge typically handles the full job.
Is the WORX 40V mower loud?
At 89dB, this mower is noticeably quieter than most gas-powered models, which commonly operate at 95dB or louder. Customers specifically note that hearing protection is not needed during normal use.
This makes it a considerate option for early-morning mowing or homes in close-knit neighborhoods.
Does the WORX WG779 come with batteries, or do I need to buy them separately?
Both 40V 4.0Ah batteries and the charger are included in the box , no separate battery purchase required. This is one of the more compelling value aspects of this mower, since replacement or additional 40V batteries can investment - each when purchased separately.
Can this mower handle thick or tall grass?
The WORX 40V performs best on regularly maintained grass at standard mowing heights. For thick, tall, or overgrown grass, the 40V battery platform may bog down and reduce effective runtime per charge.
If your lawn frequently gets long between mows or has dense grass varieties, a higher-voltage or gas-powered mower would be a more dependable choice.
How does the cutting height adjustment work on the WORX 40V?
A single lever controls all four wheels simultaneously, snapping into any of 7 preset positions between 1.5 and 4.0 inches. This single-point adjustment is faster and simpler than mowers that require setting each wheel individually.
Most users can change height in under 10 seconds without tools.
Is the WORX 40V lawn mower good for RV use or small lots?
Yes , this is one of the mower's strongest use cases. The foldable handle collapses for compact storage in tight spaces, the 35.3 lb weight makes it easy to lift in and out of an RV bay or truck bed, and the battery-powered operation means no fuel storage or exhaust concerns.
Customers with RV lots and small urban or suburban yards consistently rate it highly for these scenarios.
Bottom Line
The WORX 40V 17" Cordless Lawn Mower is a well-matched tool for small yard homeowners, RV users, and eco-minded mowers who want a quiet, lightweight, low-maintenance electric option. With two batteries included and a push-button start, the barrier to mowing is genuinely low.
Those with larger properties, steep slopes, or consistently overgrown grass will want to look at more powerful or self-propelled alternatives.
Best for small flat yards under 5,445 sq ft where quiet, emission-free, low-effort mowing is the priority.
Consider alternatives if your yard exceeds 5,445 sq ft, features hilly terrain, or your grass frequently grows thick and tall between mows.
