Pros
With thousands of reviews highlighting its user-friendly design, this mower shines in everyday use. Here are the top advantages:
- Ultra-Lightweight and Easy to Maneuver: At 35% lighter than gas mowers, it’s a breeze to push, especially on flat terrain. Reviewers rave about the ergonomic handles and lack of vibration, making it ideal for seniors, those with back issues, or anyone prioritizing comfort.
- Impressive Battery Life for Small Yards: The 4.0Ah battery handles ¼-acre lots in one charge (35-45 minutes), with simple swap compatibility for Greenworks’ ecosystem. Users love not dealing with gas stations or fumes.
- Whisper-Quiet Operation: Under 75dB, it’s neighborhood-friendly—no early morning complaints. One reviewer noted, “The mower operates smoothly – is very quiet and light weight.”
- No Maintenance Hassles: Forget oil changes or spark plugs. It’s emissions-free, saving money and storage space (no gas cans needed).
- Easy Setup and Adjustments: Assembles in minutes—just attach the handle extension and grass bag. Single-lever height adjustment adapts to any grass type effortlessly.
- Versatile 2-in-1 System: Mulch for nutrient return or bag clippings effectively. Many prefer mulching for its simplicity.
- Great Ecosystem Value: Battery interchanges with 75+ tools, expanding your cordless arsenal without extra purchases. A 5-star user said, “Bought several other tools from this company and am happy with them all.”
Cons
No mower is perfect, and this one’s limitations show up in tougher conditions. Based on critical reviews, here are the main drawbacks:
- Struggles with Tall, Wet, or Thick Grass: It bogs down in overgrown lawns (over 7 inches) or damp conditions, requiring slower passes or frequent stops. One user reported jamming from long grass and leaves, taking twice as long as a gas mower.
- Narrow 16″ Cutting Deck: Smaller width means more passes and longer mowing times compared to 20-21″ models. Lazy reviewers wish for wider coverage to save time.
- No Self-Propelled Feature: As a push mower, it’s tiring on hills, bumpy yards, or for less mobile users. A reviewer with a bad back said, “I probably should have paid the extra… for the self-propelled model.”
- Bagging Inefficiencies: Catches only 50-90% of clippings; the rest mulches on the lawn, requiring extra raking. Setup can be tricky at first.
- Durability Concerns: Plastic-heavy build and wheels raise long-term questions, though most hold up after a season.
Customer Reviews Analysis
With 19,755 reviews averaging 4.2 stars, the consensus is positive for everyday use but tempered by performance limits. About 70% are 4-5 stars, praising ease and quietness, while 1-2 star reviews focus on power shortcomings.
Positive Highlights
Five-star users love the transition from gas. One detailed review after months of use: “We have a little over a 1/4 acre… One battery will usually do the whole yard – about 35-45 minutes… No vibration. No running to get gas… Great product.” They appreciated mulching, battery sharing with trimmers and blowers, and simplicity.
Another in Spanish (translated): “Out of the box… good size, not heavy, not noisy… Power adequate for normal grass. Leaves it well cut and all goes to the bag! Recommended for small gardens.” Quick setup and clean cuts won them over.
Common themes: Quiet (no waking neighbors), lightweight (easy for women/kids), storage-friendly, and cost savings.
Negative Feedback
Lower ratings emerge in challenging scenarios. A frustrated buyer with overgrown, wet grass: “Only got half the back yard done… clippings jamming up the blade… had to keep stopping to rake.” They noted poor bagging (half clippings missed) and wished for a wider model.
Another updated from 3 to 4 stars after better conditions: “Definitely weaker than a gas engine… struggled with longer, wetter grass… but in normal conditions, it was a delight.” They highlighted slower speed in tough spots and a “kiddie” plastic look but loved no gas smell.
Trends: 20-30% complain about power on tall/wet grass, hills, or leaves; bagging clogs; and runtime dipping in heavy use. However, many improve habits (mow weekly) and report satisfaction long-term.
Overall, it’s a hit for flat, maintained lawns but not for neglected or large properties.
Who Should Buy This Product
This Greenworks mower is ideal for:
- Homeowners with small to medium flat yards (up to ½ acre, ideally ¼ acre) who mow weekly.
- Eco-conscious users seeking quiet, emission-free operation without gas hassles.
- Greenworks ecosystem owners—maximize your 40V batteries across tools.
- Beginners to cordless mowing or those with physical limitations (lightweight, no pull-start).
- Budget buyers wanting a complete kit under $250 with strong warranty.
Avoid if you have hilly terrain, very large lawns, or frequently face overgrown grass—opt for self-propelled or gas models instead.
Final Verdict
The Greenworks 40V 16″ Cordless Lawn Mower earns a solid 4.2 out of 5 stars from me, mirroring its Amazon rating. It excels as an entry-level cordless option: lightweight, quiet, maintenance-free, and versatile within the Greenworks family. For flat, small yards, it’s a game-changer—saving time, money, and sanity compared to gas.
However, its push design and power limits make it unsuitable for tough conditions, where it lags behind gas or premium electrics. At $239 with battery included, it’s excellent value if it matches your yard. Recommended for casual mowers prioritizing ease over raw power.
If you’re ready to go cordless, this mower could be your gateway to a simpler lawn care routine. Happy mowing!
