Greenworks 40V 16 (Push) Cordless Lawn Mower, 4.0Ah Battery Review: The Truth About Push Lawn Mowers

Most of us are tired of the weekend ritual involving spilled gas, yank-cords, and finding space for a massive steel machine in a crowded garage. With a 4.2-star rating from over 11,700 owners, this specific Greenworks model keeps coming up as the practical answer to normal yard work.

When shopping for push lawn mowers, it is incredibly easy to buy an 80-volt, self-propelled monster that you simply do not need. The reality of a standard 1/3-acre suburban lot is that a lightweight, 16-inch deck is usually more than enough, saving you hundreds of dollars and a lot of backache.

Homeowners consistently gravitate to this $249.99 unit because it requires zero winterization and starts with a simple button press. It cuts down the Sunday morning chore to just getting out there, walking the grass, and getting back inside before the neighborhood wakes up.

The Bottom Line

The Verdict: At just under $250, it is a highly capable, basic machine that spares you the heavy premium of industrial-grade equipment while still delivering the power required for standard residential grass.

Ideal For: The person who needs to do a quick Sunday cleanup before the HOA notices, or anyone dealing with steep hills where a heavy gas mower is too hard to handle.

The Tradeoff: The 16-inch grass collection bag is laughably small, meaning if you prefer bagging over mulching, you will be doing a lot of walking back to the yard waste bin.

The Storage & Setup Truth

One of the biggest reliefs of owning this unit is what happens when you aren’t using it. Because it only weighs 37.5 pounds, folding the handle down and sliding it into a corner or putting it on a heavy-duty wall hook is completely doable, even if you are just moving it out of the way of a baby stroller.

  • Setup Details: You just have to snap the handle extension into place and attach the bag. It takes maybe five minutes.
  • Storage Footprint: Folded down, it easily fits right behind a trash bin without smelling like an oil refinery.
  • Authority Signal: It currently sits as the #2 bestseller in Walk-Behind Lawn Mowers and includes a 3-year warranty for peace of mind.

Where Owners Feel the Relief

  • The 35-minute battery average life is exactly enough time for a normal suburban front and back mow without stopping for a recharge.
  • People constantly mention how spookily quiet it is. You can easily listen to music or a podcast while cutting the grass.

The Practical Tradeoffs

  • The blade uses proprietary mounting holes, so you cannot easily swap it for generic aftermarket mulching blades.
  • If you wait two weeks and let the grass get thick, the motor’s torque-sense feature works harder and drains the battery twice as fast.

Where It Actually Saves Your Weekend

Anyway, most of the 11,700+ reviews focus on just how much easier this is to push around on hills. Because there is no heavy engine block, the lack of a self-propelled drive system isn’t an issue.

You can adjust the cutting deck from 1.25 inches up to 3.75 inches using a single lever, which saves you from messing around with individual wheel adjustments.

The Practical Reality

  • Daily Handling: The wheels are plastic but they roll fine across standard turf.
  • Ecosystem Value: The included 4.0Ah battery clicks right into more than 75 other 40V Greenworks tools, meaning you won’t need to buy extra power sources if you get the matching string trimmer later.
  • The Build: It has been a category leader for years because it avoids complicated internal mechanics. With just one moving part besides the blade, there is less that can break compared to cheap, over-complicated clones.

Numbers vs. Real Life

It helps to know what the numbers on the box actually mean when you pull it out of the garage on a Saturday.

The Spec Real-World Consequence
37.5 Pounds You can practically turn it around with one arm, making it great for tight spaces and steep hills.
16-Inch Cutting Width Takes a few more passes than a 21-inch deck, but maneuvers easily around flower beds and swing sets.
11,789 Reviews A massive sample size of long-term owners proving the motor holds up across multiple seasons.

Keeping It Headache-Free

The plastic deck gets dusty pretty quickly, so wipe it down once in a while or dirt smears will stay there forever. Also, the blade does lose its edge a bit fast, so you’ll want to touch it up with a file after a few cuts.

Never lose the little electric safety key jumper. If it falls out of your pocket or you misplace it in the garage, the mower will absolutely not start and finding a replacement part is an annoyance you do not want.

Who Should Still Look Elsewhere

Sometimes people see the price and forget that this is built for standard, regular upkeep. If you have serious acreage, an 80V or heavy gas alternative makes sense, even if it adds 40 pounds of extra weight.

  • LawnMaster 48V MAX Electric Mower: A better bet for the heavy-duty user who wants a larger 19-inch deck and needs more bagging capacity for thick, tall weeds.
  • A Basic Corded Mower: If you only have a tiny 10×10 patch of grass in a townhome, skip the battery ecosystem entirely and get a cheap plug-in model.

The Smart Buy for Standard Homes

When you look at the landscape of push lawn mowers, the Greenworks 40V 16-inch model remains the safe, pragmatic bet for an average home. It skips the expensive bells and whistles in favor of a reliable cut.

  • Buy it if: You have a flat or moderately sloped yard under 1/3 acre and want something under 40 pounds.
  • Skip it if: You let your grass grow tall for weeks at a time and strictly prefer bagging your clippings.
  • The Payoff: Finishing your lawn, hanging the mower on the wall, and going inside for a drink while your neighbor is still trying to mix gas and oil for their commercial rig.

Common Owner Hesitations Answered

Is the 4.0Ah battery actually enough?

Yes, but it depends on your routine. If you mow weekly, 35 minutes is highly accurate. If you let the grass turn into a jungle, the motor ramps up its power and will eat through the battery in 20 minutes.

Are the plastic parts durable?

They are basic but hold up well to normal bumps. The height adjustment lever feels solid, though the handle knobs might loosen up after a few months and need a quick retightening.

What do long-term owners say after a year?

The consensus is that the convenience far outweighs the narrow 16-inch cutting path. Most buyers end up purchasing a second tool just to have a backup battery on rotation, making the whole system work well for years.
