An electric lawn mower starts with the push of a button, runs quiet enough to mow early on a Saturday, and never needs gas, oil, or a spring tune-up. The hard part is no longer whether to go electric. It is picking the right deck width, battery, and drive type for the yard you actually mow.
This guide walks through every decision in plain terms, then matches the choices to the cordless mowers in the Wild Badger lineup so you can see exactly which model fits your yard.
The Quick Answer
Small yards up to about a quarter acre: a 14 inch or 16 inch push mower is light, easy to store, and quick to maneuver around beds and paths.
Medium yards up to roughly a third of an acre: an 18 inch push mower cuts a wider path so you finish in fewer passes without much extra weight.
Larger or sloped yards around half an acre: a 21 inch self propelled mower does the pushing for you and carries enough battery for a long session in one go.
Why Choose a Battery Powered Lawn Mower
A modern electric lawn mower runs on a lithium battery instead of a gas engine. That single change removes most of the maintenance that makes a mower a chore. There is no fuel to mix or stabilize, no oil to drain, no air filter or spark plug, and no pull cord to fight on a cold morning.
The day to day benefits add up quickly:
- Push button start every time, with full power from the first second.
- Much quieter operation, so you can mow early or late without bothering the neighbors.
- No emissions at the mower, which matters in a closed yard or near open windows.
- Far less maintenance, since a brushless motor has fewer wearing parts than a gas engine.
- Easier storage, with many decks folding flat and no fuel that can go stale over winter.
Every Wild Badger electric mower runs on the same 40V battery platform and uses a brushless motor, which delivers more torque from each charge and runs cooler over a long mow.
Step 1: Match Deck Width to Yard Size
Deck width, also called cutting width, is the single number that decides how many passes it takes to finish your lawn. A wider deck clears more grass per pass, so a big yard finishes faster. A narrower deck is lighter and turns more easily, which is what you want in a small yard full of garden beds, trees, and tight corners.
Here is a rough guide to matching deck width to yard size:
| Deck width | Best for | Why it fits |
|---|---|---|
| 14 inch | Small yards, courtyards, narrow strips | Lightest to push and easiest to store; turns tightly around beds. |
| 16 inch | Small to medium yards | A bit more cutting width while staying light and nimble. |
| 18 inch | Medium yards | Wider path finishes the lawn in fewer passes without much added weight. |
| 21 inch | Larger or sloped yards | Widest path and self propelled drive for long, less tiring sessions. |
If your yard sits between two sizes, lean toward the wider deck only if it is easy to store and turn where you mow. A wide mower that cannot get around a tight side yard slows you down more than a narrow one.
Step 2: Battery Voltage and Runtime
On a cordless lawn mower, the battery is the fuel tank. Two things decide how long you can mow: the voltage of the platform and the amp hours of the pack.
Voltage sets the power
Voltage is a rough measure of how much power the motor can draw. A 40V platform has enough torque to power through damp grass and the slightly taller growth you get between mows, which is where lower voltage tools tend to bog down. All Wild Badger electric mowers share the same 40V system, so batteries and chargers move between tools in the range.
Amp hours set the runtime
Amp hours, written as Ah, tell you how much energy the pack holds. A higher Ah rating runs longer before it needs a charge. As a guide, a 4Ah pack covers a small to medium yard on a single charge, and pairing two packs is what lets a larger mower run a long session without stopping.
For example, the 21 inch self propelled model ships with two 40V 4Ah batteries and a charger, and Wild Badger rates it for up to 88 minutes of continuous runtime. That is enough headroom to finish a half acre lawn in one pass and keep a spare charge in reserve.
A simple rule helps here: if your current gas mow takes more than 30 minutes, plan on two batteries so you are never caught with a dead pack halfway through.
Step 3: Push or Self Propelled
A push mower moves because you push it. A self propelled mower has a drive system that turns the wheels, so you steer and it pulls itself forward. The right choice comes down to yard size and terrain.
- Choose a push mower for small to medium flat yards. It is lighter, simpler, and easier to maneuver, and on a small lawn you finish before fatigue is ever a factor.
- Choose a self propelled mower for larger yards, slopes, or any lawn where you currently feel worn out by the end. The drive system carries the mower up inclines and over long stretches so your arms are not doing the work.
The 21 inch model adds a 3 speed drive, so you can match the mower pace to your walking speed rather than the other way around.
Step 4: Cutting Height and Adjustments
Cutting height controls how short the mower cuts, and being able to change it easily matters more than most buyers expect. Taller grass shades out weeds and holds moisture in summer, while a lower cut suits early spring and fall cleanup.
Look for a single lever that raises and lowers the whole deck at once rather than adjusting each wheel separately. The Wild Badger push mowers offer 5 height settings, and the 21 inch self propelled model offers 7 settings across a roughly 1.18 to 3.55 inch range, which covers everything from a tidy summer lawn to a longer, healthier cut.
Step 5: Motor and Build Quality
One spec is worth checking on any electric mower: whether the motor is brushless. A brushless motor has no carbon brushes to wear down, so it runs more efficiently, stays cooler, and lasts longer than an older brushed design. It also squeezes more cutting out of every charge. All four Wild Badger electric mowers use brushless motors, so this is covered across the range.
Matching Wild Badger Electric Mowers to Your Yard
Once you know your yard size and whether you want push or self propelled, the choice narrows fast. Here is how the current cordless lawn mower lineup lines up:
| Model | Deck | Drive | Best for |
|---|---|---|---|
| 40V 14 inch brushless mower | 14 in | Push | Small yards and tight, bed heavy layouts |
| 40V 16 inch brushless mower | 16 in | Push | Small to medium yards wanting a wider path |
| 40V 18 inch brushless mower | 18 in | Push | Medium yards, fewer passes to finish |
| 40V 21 inch self propelled mower | 21 in | Self propelled | Larger or sloped yards, long sessions |
Because all four share the 40V battery platform, the batteries and charger you buy with one mower also work with other 40V Wild Badger tools, which keeps the cost of building out a yard kit down over time.
Frequently Asked Questions
Are electric lawn mowers powerful enough for thick grass?
A 40V brushless mower has the torque to handle damp grass and the taller growth between mows, which is where weaker tools stall. The main limit is runtime rather than power, so for thicker or larger lawns the answer is usually a second battery, not a stronger motor.
How long does an electric lawn mower battery last per charge?
It depends on the pack and the grass. As a guide, a single 4Ah pack covers a small to medium yard, and running two packs is what gets you through a larger lawn. The 21 inch self propelled model, for example, is rated for up to 88 minutes on its two included batteries.
What size lawn mower do I need for my yard?
Match deck width to yard size. A 14 to 16 inch deck suits small yards, an 18 inch deck suits medium yards, and a 21 inch deck suits larger yards. If your yard is large or sloped, choose a self propelled model so the mower carries itself rather than relying on you to push it.
Do I still need to maintain an electric mower?
Far less than a gas mower. There is no oil, fuel, filter, or spark plug to service. Upkeep comes down to keeping the deck clean, charging the battery, and sharpening or replacing the blade once a season.
Is a cordless mower better than a gas mower?
For most home yards, a cordless mower wins on noise, convenience, and maintenance, with no fumes and a button start. Gas still holds an edge for very large acreage where you would otherwise carry several batteries. For the typical residential lawn, an electric mower covers the job comfortably.
