The 7 Best Push-Button Start Lawn Mowers of 2026, Ranked & Reviewed

By the Primea Editorial TeamUpdated November 1, 202610 min read7 products ranked

The short answer

The EGO Power+ LM2134SP-2 is the best push-button start lawn mower, a 21 inch self-propelled model with a push-button key start on a cordless battery platform. The Greenworks 80V gives self-propel for less with a 4.0Ah pack included, and the EGO LM2114 is the push-drive 21 inch option. The Greenworks 60V and 40V, MZK and KOMASTY serve push-mowing and small-lawn needs.

A push-button start sounds like a small convenience until you stand over a gas mower on a cold morning with a sore shoulder. The trap is that battery mowers differ wildly in what ships in the box. Some sell a bare tool, some include one battery, and a few add a spare, and the sticker price tells you nothing about which you are getting.

Seven mowers made this ranking after a read of their spec pages, with battery platform, deck width, drive type and included items doing most of the work in the Primea score. Prices appear as buckets. Every pick lists a key start, so the real choice is between a full 21 inch deck, a compact 16 inch one, and whether the wheels drive themselves.

Before you buy

What Actually Matters

Push-button key start

A push-button key start replaces the pull cord with a safety key and a button. It matters because there is no yanking, which helps anyone with a bad shoulder or a fear of kickback. Look for push-button in the title or bullets, and check that the key must be inserted before the mower runs. A removable key also stops children starting it.

Self-propelled vs push

Self-propelled mowers drive their own wheels. They help on slopes and big lawns but add weight and cost. Look for the self-propelled label, and weigh whether your lawn is large or sloped enough to justify a heavier machine, because push models are easier on small yards. A drive also saves effort when the bag is full.

Battery voltage and Ah

Volts set the power platform and amp-hours set runtime. A 5.0Ah pack runs longer than a 4.0Ah one. Check both numbers and the charger, and confirm the battery is in the box, because a bare tool listing can cost more once you add a pack. Battery cost is the main hidden expense.

Deck width

A 21-inch deck covers more per pass than a 16-inch deck. A wider deck is heavier and harder to store. Match width to lawn size, and think about storage space, since a big deck needs a larger shed or garage corner. Foldable handles help in a tight space.

What is in the box

Some listings include a spare battery or second charger. That can change the effective price, as with the KOMASTY's two packs. Read the included items line, and compare the total value, not the sticker price alone, because the battery is often the costliest part. A spare pack doubles your mowing time.

Our Ranked Picks, Reviewed

Best Overall

EGO Power+ 21-Inch Cordless Electric Self-Propelled Lawn Mower (LM2134SP-2)

Outstanding

Check price on Amazon

Our verdict: Push-button key start and self-propelled drive on a full 21 inch deck.

The EGO LM2134SP-2 has a 21-inch deck, self-propelled drive and a push-button key start on EGO's cordless battery platform, in the $500 and up bucket. Self-propel drives the wheels for you, which turns a slope or a big lawn from a chore into a walk.

It ranks first because it combines the two features this guide cares about, an easy start and a drive, on a full-width deck. The Greenworks 80V matches it on features while dropping a price tier, which makes it the value rival.

Buy it for a larger lawn where both features pay off. The caveats are the top price tier and the added weight of the drive system. Skip it if you want to spend under $500.

Deck: 21 inches
Drive: Self-propelled
Start: Push-button key start
Power: Cordless battery platform

What we like

+Self-propelled drive
+Push-button key start
+Full 21-inch deck
+Cordless platform

Watch out for

−Highest price tier
−Heavier than push models

Buy it if: Buyers wanting push-button starting plus self-propel.

Skip it if: You want to spend under $500.

Best Value Self-Propelled

Greenworks 80V 21-Inch Self-Propelled Lawn Mower, 4.0 Ah Battery and Charger

Outstanding

Check price on Amazon

Our verdict: Self-propelled with an 80V 4.0Ah pack for less than the EGO.

The Greenworks 80V has a 21-inch deck, self-propelled drive, a push-button key start and an 80V 4.0Ah battery plus charger in the box, in the $200 to $500 bucket. An 80V pack carries a higher voltage than the 40V and 60V models, which suits the extra load of a drive system.

It ranks second because it matches the EGO LM2134SP-2 on features while dropping into the $200 to $500 bucket, with the battery already included. You give up the EGO platform and the brand's reputation.

Buy it for self-propel at a lower price. The caveats are a different battery ecosystem and added weight. Skip it if you already own EGO batteries.

Deck: 21 inches
Battery: 80V 4.0Ah included
Drive: Self-propelled
Start: Push-button key start

What we like

+Self-propelled drive
+80V battery included
+Push-button key start
+Under $500

Watch out for

−Greenworks battery ecosystem

Skip it if: You already own EGO batteries.

Best Push-Drive 21 Inch

EGO POWER+ 21-Inch Cordless Electric Lawn Mower with Battery, Charger (LM2114)

Excellent

Check price on Amazon

Our verdict: A 21 inch push mower on the 56V platform, battery included.

The EGO LM2114 has a 21-inch cutting deck, a 56V battery platform, a battery and charger in the box and a push drive, in the $200 to $500 bucket. A push mower is lighter than a self-propelled one, which matters for storage and lifting.

It ranks third because it drops the self-propel of the two above, which means more effort on larger lawns. It stays on a respected platform, and the box includes everything you need.

Buy it for standard-size lawns. The caveats are no self-propel and effort on bigger yards. Skip it if you want drive assistance.

Deck: 21 inches
Power: 56V battery platform
Drive: Push
Included: Battery and charger

What we like

+21-inch cutting deck
+Battery and charger included
+56V platform
+Lighter push design

Watch out for

−No self-propel
−Push effort on large lawns

Buy it if: Standard-size lawns.

Skip it if: You want drive assistance.

Best Full-Width Push

Greenworks 60V 21-Inch Push Lawn Mower, 5.0 Ah Battery and Charger

Excellent

Check price on Amazon

Our verdict: A 21 inch push deck with a 60V 5.0Ah pack included.

The Greenworks 60V has a 21-inch deck, a 60V 5.0Ah battery with charger included, push drive and a push-button key start, in the $200 to $500 bucket. A 5.0Ah pack runs longer than a 4.0Ah one at the same voltage, which means more lawn per charge.

It ranks fourth because it offers a bigger pack than the Greenworks 80V but no self-propel. Against the EGO LM2114, it trades a respected platform for a larger battery.

Buy it for full-width push mowing without paying for self-propel. The caveats are no drive assistance and a different battery platform. Skip it if you want a self-propelled drive.

Deck: 21 inches
Battery: 60V 5.0Ah included
Drive: Push
Start: Push-button key start

What we like

+5.0Ah battery included
+Full 21-inch deck
+Push-button key start
+No self-propel cost

Watch out for

−No drive assistance
−Different battery platform

Buy it if: Full-width push mowing without paying for self-propel.

Skip it if: You want self-propelled drive.

Best Compact

Greenworks 40V 16-Inch Push Lawn Mower, 4.0 Ah Battery and Charger

Very Good

Check price on Amazon

Our verdict: A compact 16 inch push-button mower with battery included.

The Greenworks 40V has a 16-inch deck, a 40V 4.0Ah battery and charger included, push drive and a push-button key start, in the $200 to $500 bucket. A 16 inch deck is light and slips into a small shed, which suits a townhouse lawn.

It ranks fifth because the deck is five inches narrower than the 21-inch group, though it is easier to store and handle. You make more passes, which costs time on anything bigger than a small yard.

Buy it for small lawns where compactness matters. The caveats are the narrower deck and a price above generic 16-inch models. Skip it if you have a standard-size lawn.

Deck: 16 inches
Battery: 40V 4.0Ah included
Drive: Push
Start: Push-button key start

What we like

+Compact 16-inch deck
+Battery and charger included
+Push-button key start
+Easy to store

Watch out for

−Narrower deck
−Pricier than generic 16-inch

Buy it if: Small lawns where compactness matters.

Skip it if: You have a standard-size lawn.

Best Budget Brushless

MZK 40V 16-Inch 2-in-1 Brushless Cordless Push Lawn Mower

Very Good

Check price on Amazon

Our verdict: A 16 inch brushless 2-in-1 with a push-button key start.

The MZK has a 16-inch deck, a 40V battery platform, a brushless motor and a push-button key start, as a 2-in-1 push mower, in the $100 to $200 bucket. A brushless motor wears less than a brushed one and wastes less battery as heat.

It ranks sixth because it is from a lesser-known brand and the listing does not say what battery is included, which matters when the pack is the expensive part. It undercuts the Greenworks 40V on price.

Buy it for budget buyers with small lawns. The caveats are the unknown brand and unlisted battery details. Skip it if you want a major battery ecosystem.

Deck: 16 inches
Power: 40V battery platform
Motor: Brushless
Start: Push-button key start

What we like

+Brushless motor
+Push-button key start
+16-inch deck
+Lower price

Watch out for

−Lesser-known brand
−Battery details not listed

Buy it if: Budget buyers with small lawns.

Skip it if: You want a major battery ecosystem.

Best Spare Battery Included

KOMASTY 40V 16-Inch Cordless Battery Powered Lawn Mower, 2-in-1 Mulching

Very Good

Check price on Amazon

Our verdict: Two 4.0Ah batteries and two chargers at the lowest price.

The KOMASTY has a 16-inch deck, a 40V battery platform and a push-button key start, and it includes two 4.0Ah batteries and two chargers, in the $50 to $100 bucket. It is a 2-in-1 mulching design. Two batteries mean you can swap a charged pack mid-job.

It ranks last because the brand is the least established, and a narrow deck means more passes. It is the cheapest mower here, and the spare battery doubles the runtime.

Buy it for tight budgets that want a spare battery. The caveats are the unproven brand and the narrow deck. Skip it if you prefer an established brand.

Deck: 16 inches
Batteries: Two 4.0Ah, two chargers
Start: Push-button key start
Type: 2-in-1 mulching

What we like

+Two batteries included
+Two chargers included
+Push-button key start
+Lowest price here

Watch out for

−Unproven brand
−Narrow 16-inch deck

Buy it if: Tight budgets that want a spare battery.

Skip it if: You prefer an established brand.

Questions

Frequently Asked Questions

What is a push-button key start?+

You insert a safety key and press a button instead of pulling a cord. All seven picks list it, so the start system does not separate them. Deck, drive and included battery do.

What mistake do buyers make?+

They buy a bare tool without a battery. Check the included items before ordering, as the EGO and Greenworks listings state their batteries. The MZK listing does not, so ask before buying.

Is self-propelled worth it?+

On a large or sloped lawn, yes. On a small lawn the extra weight is not worth it, and the 16 inch models stay easy to push. Slopes and wet grass are where a drive earns its cost.

How do I set up a battery mower?+

Charge the battery, insert it, insert the key and press the button. Follow the manual's safety steps for the EGO or Greenworks model, and always remove the key before clearing a jam.

How do I maintain it?+

Clean the deck after use and store the battery indoors. Check the manual for blade guidance, and avoid leaving a battery in a hot shed, since heat shortens its life.

Do these mulch?+

The MZK and KOMASTY are 2-in-1 designs, and the KOMASTY is listed as mulching. Check the others on their product pages, because the listing for each model may or may not mention a mulch plug.

Final take

Buy the EGO LM2134SP-2 if you want an easy start and a drive, and the Greenworks 80V for self-propel at a lower price. The EGO LM2114 and Greenworks 60V suit standard lawns that do not need drive assistance. The 16 inch Greenworks, MZK and KOMASTY fit small yards. Confirm what is in the box, because the battery is the expensive part.
