Quick Verdict
Rating: 2.8/5 — Not recommended for most buyers.
The 40V Cordless Self-Propelled Electric Lawn Mower Brushless has an attractive spec sheet — self-propelled drive, brushless motor, dual 5.0Ah batteries, mulching and bagging — all at $170. But a 2.8 out of 5 star rating from only 24 reviews is a serious warning sign. Features on paper mean little if runtime, power delivery, or long-term reliability fall short in real use.
Buy it only if: you specifically want self-propelled assistance on a tight budget and can accept the risk of a poorly rated, unproven product. Skip it if: you want dependable performance and solid after-sales support — established name-brand entry-level cordless mowers cost only slightly more and carry far more user confidence.

Pros & Cons
What We Like
- Self-propelled drive reduces physical effort. Adjustable speed (1.4–2.9 mph) is genuinely useful on slopes, thick grass, or for anyone who doesn’t want to push a mower manually — a real advantage over cheaper push-only models.
- Two 5.0Ah batteries add practical value. Runtime is the classic weakness of budget battery mowers. Two batteries in the box means, in theory, you can finish a small-to-medium yard without interruption.
- Brushless motor should improve efficiency and lifespan. Brushless designs typically deliver better energy use, less maintenance, and longer motor life than brushed equivalents — if well implemented.
- 2-in-1 mulching and bagging. Mulch to return nutrients to the lawn, or bag for a cleaner finish. Versatility budget mowers often lack.
- Six cutting heights (1–3 inches). A single-lever adjustment is convenient and gives seasonal flexibility for different grass types and conditions.
- Z-fold handle simplifies storage. Folds compactly for a garage, shed, or tight corner.
- No gas, no oil, no tune-ups. If the mower holds up, long-term maintenance costs are far lower than a gas equivalent.
What We Don’t Like
- The 2.8-star rating is the biggest red flag. This is not a minor dip — it suggests widespread dissatisfaction, usually pointing to problems with durability, power, assembly quality, battery life, or customer support.
- Runtime may be too short in real conditions. The advertised 30 minutes shrinks fast with thick grass, slopes, damp grass, or when running the self-propelled drive constantly.
- An 18-inch deck is slow for larger lawns. Fine for small yards, but buyers with bigger properties will spend far more time mowing than they’d like.
- Battery warranty is shorter than the tool warranty. Three years on the tool sounds decent, but only one year on the batteries is a concern given that batteries are typically the first (and most expensive) component to fail.
- Low review volume means limited real-world evidence. With only 24 ratings, there’s no large user base confirming long-term reliability — you’re essentially an early adopter.
Performance Analysis
Cutting Power and Motor
The brushless motor rated at up to 3600 RPM is a promising specification — brushless motors generally convert battery power into cutting torque more efficiently than brushed units. But specs don’t cut grass; voltage under load does. With a 2.8-star average, a pattern common to poorly rated budget mowers is stalling or bogging down in thick or tall grass, and there’s nothing in the review record to suggest this model escapes that pattern. If your lawn is regularly overgrown or dense, treat the power claims skeptically.
Runtime and Batteries
Two 5.0Ah batteries at 40V is a respectable package on paper — enough, in ideal conditions, for roughly an hour of combined mowing. But the 30-minute per-battery figure assumes light load. Self-propelled drive, thick grass, and slopes can each cut runtime meaningfully. The bigger issue is the 1-year battery warranty: if batteries degrade quickly, you could face an expensive out-of-warranty replacement on a product you bought to save money.
Self-Propelled Drive
The adjustable drive (1.4–2.9 mph) is the feature that most justifies a premium over cheap push mowers — and also the feature most likely to fail on budget machines. Drive belts, wheels, and transmission linkages are common failure points in low-cost self-propelled mowers. With a low review score and thin warranty coverage, this is a meaningful risk.
The Value Equation
Here’s the core buying decision: at $170, this mower undercuts most name-brand 40V self-propelled mowers significantly. If it performed as advertised, that would be strong value. But a 2.8-star score flips the math — a cheap mower that fails after one season (or arrives defective) costs more per mow than a $250–300 model from a brand with established support. You’re not saving $100; you’re gambling it.
Frequently Asked Questions
Is the 40V Cordless Self-Propelled Electric Lawn Mower worth $170?
For most buyers, no. The price is attractive, but a 2.8/5 rating from 24 reviews indicates significant real-world disappointment. Only consider it if self-propulsion on a tight budget is your priority and you’re comfortable with return-window risk.
How long do the batteries last on a single charge?
The manufacturer advertises up to 30 minutes per 5.0Ah battery. Expect less in demanding conditions — thick grass, slopes, or constant self-propelled use can reduce that noticeably. With both batteries, plan on roughly 45–60 minutes of realistic mowing time.
What size lawn is this mower suitable for?
The 18-inch deck and dual-battery setup suit small to medium yards — roughly up to a quarter acre in ideal conditions. Larger lawns will mean frequent battery swaps and long mowing sessions.
What is covered by the warranty?
The mower carries a 3-year warranty, but the batteries are covered for only 1 year. Since batteries are typically the first component to fail on cordless mowers, read the warranty terms carefully before buying.
Can it mulch and bag at the same time?
No — it’s a 2-in-1 design, meaning you choose mulching or bagging depending on which accessory is installed, not both simultaneously.
What are better alternatives to this mower?
If your budget is around $170, a well-reviewed push cordless mower from an established brand will likely serve you better than a poorly rated self-propelled model. If self-propulsion is essential, entry-level 40V self-propelled mowers from major brands typically start around $250–300 and come with proven support networks. See our cordless self-propelled lawn mower comparison for options.
Final Verdict
The 40V Cordless Self-Propelled Electric Lawn Mower Brushless is a case of a compelling spec sheet attached to an unproven — and poorly reviewed — product. Self-propulsion, dual batteries, and a brushless motor at $170 would be a standout deal if reliability were there, but the 2.8-star rating suggests it likely isn’t. The short battery warranty and small review base compound the risk. Our recommendation: spend a bit more on a better-established alternative unless you’re willing to accept the gamble.
