What Sets It Apart
Key specification highlights based on our analysis.
Steel Cutting Deck
Durable steel deck for long-term use
Why We Recommend It
- 01.
Two 4.0Ah rechargeable batteries included , no extra purchase needed, and combined runtime covers most small yards in one session
- 02.
Brushless motor technology runs cooler and more efficiently than brushed motors, extending both battery life and motor lifespan
- 03.
Steel cutting deck offers durability that outlasts plastic decks common in this tier
- 04.
6-position individual wheel height adjustment (0.98" to 2.95") gives fine-grained control for different grass types and seasonal conditions
- 05.
20V/40V tool platform compatibility means batteries work across compatible LIGO tools, increasing the investment's overall value
Considerations
- 01.
15-inch cutting deck is efficient for small spaces but will require significantly more passes on mid-size or large yards, making it impractical for properties over 1/4 acre
- 02.
Rear-bag-only discharge means no mulching or side-discharge option , you'll need to stop and empty the 11-gallon bag periodically on longer sessions
- 03.
At 40 minutes per battery, runtime may fall short on dense, overgrown grass that draws more power from the motor

Power & Performance
The LIGO 40V brushless motor delivers consistent cutting power well-suited for maintained, regularly cut grass on small properties. Brushless motor technology means less energy wasted as heat, so more of the 4.0Ah battery capacity translates directly into cutting performance.
For light to moderate grass conditions on flat terrain, the power output is more than adequate , though very thick or overgrown grass will draw heavier current and reduce your effective runtime per charge.
Cutting System
The 15-inch steel cutting deck strikes a balance between maneuverability in tight spaces and reasonable coverage per pass. Steel construction provides better resistance to impact and long-term warping compared to plastic decks.
The 6-position individual wheel height adjustment allows cuts ranging from a tight 0.98 inches up to a generous 2.95 inches, accommodating everything from fine lawn finishing to taller, less-manicured grass. Clippings are channeled into the included 11-gallon rear collection bag , a large capacity for this deck size that reduces how often you'll need to stop and empty.
Drive & Handling
This is a manual push mower, so forward motion is entirely user-powered , at 37 pounds, it's light enough for most adults to maneuver comfortably on flat ground. The 9-inch rear wheels and 7-inch front wheels provide decent traction on level turf.
The compact 15-inch footprint makes it easy to navigate around garden beds, trees, and obstacles that would slow down a wider deck. Without self-propulsion, it's best reserved for flat or gently sloping yards.
Battery / Fuel
The LIGO 40V system uses 4.0Ah lithium-ion rechargeable batteries, and the mower ships with two batteries plus a charger , a notable value inclusion. Each battery delivers approximately 40 minutes of runtime under normal mowing conditions, giving you roughly 80 minutes combined before needing to recharge.
The 20V/40V tool platform compatibility (LI-100M TP) means these 2X4.0Ah batteries can also power compatible LIGO tools, making the battery investment versatile. No fuel mixing, no seasonal storage concerns, and no pull-cord starts , just charge and go.
Who Is This Mower For?
Ideal For
- ✓ Small yard homeowners (under 1/4 acre) who need a nimble, easy-to-maneuver push mower that handles tight corners and landscaping
- ✓ Eco-conscious users wanting zero direct emissions and quieter operation compared to gas-powered alternatives
- ✓ Existing LIGO 20V/40V tool platform users who can share rechargeable batteries across their tool collection for added value
- ✓ Low-maintenance seekers who want push-button electric start with no oil changes, spark plug replacements, or fuel stabilizer headaches
Not Ideal For
- ✕ Owners of medium to large yards (1/2 acre or more) , the 15-inch deck and 40-minute per-battery runtime will make mowing inefficient and time-consuming
- ✕ Hilly or uneven terrain users , this is a push mower with no self-propelled drive, making slopes significantly more physically demanding
- ✕ Users who prefer mulching or side discharge , the LIGO LI-100M TP only supports rear bagging, which limits flexibility in clipping management
Cordless push mowers of this style typically require attaching the handle, connecting the grass bag, and inserting the batteries , a process most users complete in under 20 minutes without special tools. The included charger means you can be ready to mow with a full charge before you even fully unbox everything.
Fully charge both batteries before first use to ensure maximum runtime and condition the cells from the start
Confirm handle folding is fully locked before mowing , an improperly latched handle can affect steering control and comfort
Warranty details for the LIGO 40V Cordless Lawn Mower should be verified directly with the manufacturer or retailer at time of purchase, as coverage terms can vary by region and sales channel. For any support or warranty claims related to the LI-100M TP battery platform or the mower itself, contacting LIGO customer service directly is recommended.
FAQ
Does the LIGO 40V mower come with batteries, or do I need to buy them separately?
The LIGO 40V Cordless Lawn Mower includes two 4.0Ah rechargeable batteries and a charger in the box , no separate purchase needed. That gives you approximately 80 minutes of combined runtime right out of the box, which is enough for most small yards in a single session.
How big of a yard can this mower handle on a single charge?
Each 40V 4.0Ah battery provides roughly 40 minutes of runtime under normal mowing conditions. With both batteries, you're looking at about 80 minutes total , enough to comfortably cover yards up to about 1/4 acre on a single combined charge.
For larger properties, the 15-inch deck width and limited runtime per battery will make the job significantly more time-consuming.
Is the LIGO 40V mower compatible with other 20V or 40V LIGO tools I already own?
Yes , the mower uses the LIGO 20V/40V tool platform (LI-100M TP), which means the included 2X4.0Ah batteries are cross-compatible with other tools in that platform family. This is a real advantage if you're already invested in the LIGO battery ecosystem, as it reduces the need to purchase additional battery packs for other tools.
Can the LIGO 40V mower mulch grass clippings, or does it only bag?
The LIGO LI-100M TP mower is designed for rear-bag discharge only , it does not include a mulching plug or side-discharge chute. The 11-gallon collection bag is generously sized for a 15-inch deck, so you won't need to empty it as frequently as smaller bags, but mulching enthusiasts will need to look at other models.
How hard is it to push, and will it work on a slightly hilly yard?
At 37 pounds, the LIGO 40V mower is relatively lightweight and manageable for most adults on flat or gently rolling terrain. However, because it has no self-propelled drive system, any incline adds meaningful physical effort.
For yards with significant slopes or hills, a self-propelled model would be a more practical and comfortable choice.
What is the cutting height range, and can it handle both short and tall grass?
The mower offers 6 height positions ranging from 0.98 inches up to 2.95 inches, adjusted individually at each wheel. The lower end suits fine, regularly maintained lawns, while the upper positions work well for taller grass or when you want to leave more blade length for lawn health.
Keep in mind that very overgrown grass will draw more power and reduce battery runtime.
Bottom Line
The LIGO 40V Cordless Lawn Mower is a well-rounded electric push mower for small, flat properties , the dual-battery bundle, brushless motor, and steel deck make it a strong value in this tier. Users who want quiet, emissions-free mowing with no maintenance headaches will find it a reliable weekend companion.
Those with larger yards, hilly terrain, or a preference for mulching should explore wider-deck or self-propelled alternatives.
Best for small flat yards under 1/4 acre where quiet, low-maintenance, zero-emissions cordless mowing is the priority.
Consider alternatives if you have slopes, a yard larger than 1/4 acre, or need mulching and side-discharge flexibility.
