Lawn Mower That Goes by Itself
As an Amazon Associate we earn from qualifying purchases. Details
A search for “lawn mower that goes by itself” usually means a self-propelled mower: a machine whose wheels drive it forward so you only walk and steer. It is not a robotic mower, which runs on its own without anyone behind it. This guide covers the battery self-propelled mowers we found on Amazon.com. For each one it reports only what the listing states: the drive type, what is in the box, the cutting width and the runtime claim. Five of the seven listings state a battery is included, and four of those also state a charger.
Quick answer
- Battery and charger listed as included: EGO LM2135SP, Greenworks 80V 21 inch, Greenworks 82V 21 inch, Greenworks 60V 25 inch.
- Battery kit listed, charger not stated: Greenworks 60V 21 inch.
- Listed as sold without a battery or charger: EGO LM2130SP.
- Not stated on the listing we read: Ryobi 40V 20 inch, which also shows no bullet points.
What “self-propelled” means on a listing
Check three places on a listing: the title, the Style or Operation Mode field, and the bullet points. “Self-propelled” in the title usually means a drive turns the rear wheels, engaged by a handle control and set by a speed dial. The Operation Mode field is not always consistent with the title. The Greenworks 60V 21 inch listing calls itself self-propelled in its title and bullets, but its Operation Mode field says Manual. When fields and title disagree, read the bullets and the owner’s manual, and ask the seller before you buy.
A self-propelled mower does not find its way around a yard, follow a boundary wire, keep a schedule or need an app. You start it, steer it and stop it. If you want a mower that runs with no one at the controls, you want a robotic model, which is a separate category.
What the drive helps with is walking. The wheels carry part of the load, and the speed control lets you set a pace. None of the listings we read gives a slope rating, so check the manual before you mow a steep bank.
How we chose the seven listings
A listing qualified if it met four tests. The title, Style field or bullets state a self-propelled drive. The mower is electric, meaning battery or corded. The listing states a cutting width. The battery and charger status can be read from the listing. Every self-propelled match we found was a battery model, so this guide does not cover corded self-propelled mowers.
Five listings were checked on 2026-10-17. Two Greenworks 60V entries come from our product cache, last checked on 2026-10-11. We did not run any of these mowers, and nothing here reports a test. Prices, star ratings and review counts are left out, because they change and are not part of the product data we record.
Comparison at a glance
The table uses only what each listing states. “Not stated” means the listing we read does not give that fact. Runtime figures are the listings’ own claims, and real runtime depends on grass height, grass condition and terrain.
| Listing | Cutting width | Battery and charger (per listing) | Runtime claim (per listing) | Weight (per listing) |
|---|---|---|---|---|
| EGO LM2135SP | 21 inches | Included: 56V 7.5Ah battery and rapid charger; extra 5.0Ah battery sold separately | Up to 60 minutes on the included battery | Not stated on the page we read |
| EGO LM2130SP | 21 inches | Not included; recommended 56V 7.5Ah battery sold separately | Up to 60 minutes with the recommended battery | 54.5 pounds |
| Greenworks 80V 21 inch | 21 inches | Included: 4.0Ah battery and 60-minute rapid charger | Up to 45 minutes on a fully charged 4.0Ah battery | 64.2 pounds |
| Greenworks 82V 21 inch | 21 inches | Included: 8.0Ah battery and dual port charger | Up to 90 minutes, varies with grass and technique | 95 pounds |
| Greenworks 60V 25 inch | 23.96 inches | Included: two 4.0Ah batteries and 80-minute fast charger | 70 minutes in a bullet; 80 minutes in a specification field | 67.2 pounds |
| Greenworks 60V 21 inch | 20.28 inches | Included: two 4.0Ah batteries (kit); charger not stated | Area claim only: up to 3/4 acre per charge | 65 pounds |
| Ryobi 40V 20 inch | 20 inches | Not stated | Not stated | Not stated |
The seven picks
The order follows the battery information on each listing. No pick ranks above another for performance, because we did not run any of these mowers.
1. EGO POWER+ LM2135SP: battery and charger listed as included
Specs (from the listing, checked 2026-10-17): 21 inch cutting width; 56V 7.5Ah battery and rapid charger included; extra 5.0Ah battery (BA2800T) ships separately; Operation Mode Automatic; cutting height 1 to 4 inches per the bullets; Touch Drive self-propel; Select Cut lower blades. Up to 60 minutes of runtime on the included battery is the listing’s claim. The page we read shows no weight.
Pros: battery and charger are in the bundle; the bullets describe a palm-touch engage and a speed dial. Cons: the runtime is a listing claim; the extra battery is a separate purchase; no weight on the page we read.
Best for: a self-propelled mower bought as a complete set. Skip if: you already own EGO 56V batteries; the LM2130SP is the same mower sold without a battery.

2. Greenworks 82V 21 inch Self-Propelled: 8.0Ah battery and dual port charger
Specs (from the listing, checked 2026-10-17): 21 inch deck; 8.0Ah battery and dual port charger included per the title; up to 90 minutes of runtime, which varies with grass and technique; up to 1.5 acres per charge (listing claim); 2.5 kW brushless drive motor; ground speed up to 3.5 MPH; 3-in-1 mulch, bag and side discharge; 2-year tool and battery warranty per the bullets; weight 95 pounds in the specification field.
Pros: the largest battery capacity and the longest runtime claim in this group; the warranty length is stated. Cons: at 95 pounds it is the heaviest listing; the product dimensions look like a shipping size, so we did not use them; a bullet says “Low to 60dB” with no test condition, so we do not use it as a noise claim.
Best for: buyers who want the most listed battery capacity and do not mind the weight. Skip if: you need to lift or carry the mower.

3. Greenworks 80V 21 inch Self-Propelled: 4.0Ah battery and 60-minute charger
Specs (from the listing, checked 2026-10-17): 21 inch deck; 4.0Ah battery and 60-minute rapid charger included per the title; up to 45 minutes on a fully charged 4.0Ah battery, which varies with grass condition and technique; rear-wheel drive with variable speed; 7 height positions; mulch, rear bag or side discharge; weight 64.2 pounds; Operation Mode Automatic. The title also says 75+ compatible tools; we did not check that claim.
Pros: battery and charger are listed as included; the drive and speed control are described; the height adjustment is stated. Cons: the 45-minute claim is the shortest runtime in this group; 64.2 pounds.
Best for: buyers who want a battery and charger in the box on a 21 inch self-propelled deck. Skip if: runtime matters most to you.

4. Greenworks 60V 25 inch Self-Propelled: two 4.0Ah batteries and charger
Specs (from the listing, cached and checked 2026-10-11): 23.96 inch cutting width, the widest in this group; two 4.0Ah batteries as a kit with an 80-minute fast charger per a bullet; runtime of 70 minutes per a bullet and 80 minutes per a specification field; speed 3.5 to 4.5 MPH per the bullets; weight 67.2 pounds; Operation Mode Automatic; 4-year warranty per the bullets.
Pros: the widest deck in the group; batteries and charger are included; the warranty length is stated. Cons: the listing gives two runtime figures, 70 and 80 minutes, so we use neither as a firm number; the height fields list a maximum below the minimum, so we did not use them; 67.2 pounds.
Best for: larger lawns where the widest deck matters. Skip if: you need one consistent runtime figure or the lightest model.

The listing does not state a charger.
Pros: a battery kit is included; the height range and warranty are stated. Cons: the Operation Mode field says Manual while the title says self-propelled, so confirm the drive; runtime is an area, not minutes; the charger is not stated; 65 pounds.
Best for: buyers who want a 60V battery kit and a self-propelled drive, once the drive is confirmed. Skip if: you cannot confirm the drive from the bullets or the manual.

6. EGO POWER+ LM2130SP: sold without battery or charger
Specs (from the listing, checked 2026-10-17): 21 inch Select Cut deck; title says battery and charger not included; 54.5 pounds; cutting height 1 to 4 inches per the bullets; Touch Drive self-propel; up to 60 minutes with the recommended 56V 7.5Ah battery, sold separately; two-bushel grass bag and IPX4 weather resistance per the bullets; compatible with EGO 56V ARC Lithium batteries per the bullets.
Pros: the lightest weight in this group at 54.5 pounds, and a bag is included. Cons: no battery or charger in the box, so the stated runtime needs a separate 56V battery and charger.
Best for: owners who already have EGO 56V batteries. Skip if: you need a complete set in one box.

7. RYOBI 40V HP Brushless 20 inch Self-Propelled: box contents not stated
Specs (from the listing, checked 2026-10-17): the title gives 40V HP Brushless, 20 inch, battery powered and self-propelled. The listing states a 20 inch cutting width, Operation Mode Automatic, a maximum cutting height of 4 inches and a plastic material. It does not state a model number, battery amp-hours, whether a battery or charger is included, weight or runtime, and it has no bullet points.
Pros: the title names a self-propelled drive on a 40V platform. Cons: several basic specifications are missing, and we could not confirm what comes in the box.
Best for: buyers who want a Ryobi model and will confirm the box contents with the seller first. Skip if: you need a full spec sheet before you buy. Our separate Ryobi 40 volt self-propelled mower guide covers this platform.

Pros and cons across the group
Most listings bundle a battery, so the cost of starting is easier to read than in many categories. Cutting widths sit in a narrow band, from 20 to 24 inches. Runtime is the least reliable figure: it is a listing claim, it is given in minutes in some listings and as an area in others, and two listings give conflicting numbers. Weight ranges from 54.5 to 95 pounds, which matters if you lift the mower into a truck or up steps.
- Stronger points across the group: five listings state a battery is included; the drive is described as self-propelled in the titles or bullets; warranty length is stated on three listings.
- Weaker points across the group: runtime is a claim that varies; weights run heavy; two listings give conflicting figures; one listing gives almost no specifications.
Worked example: the EGO LM2135SP listing claims up to 60 minutes on its included 7.5Ah battery. If a dry lawn takes about 40 minutes to mow, the claim suggests one full charge covers it. A thick or wet lawn can take much less, so treat the listing number as a starting point, not a guarantee.
Batteries and chargers: read the box contents first
Battery voltage and amp-hours here come only from the listings. The EGO listings state 56V and 7.5Ah. The Greenworks 80V listing states a 4.0Ah battery, the 82V listing states an 8.0Ah battery, and the two 60V listings state two 4.0Ah batteries as a kit. The Ryobi listing states 40V but no amp-hour figure.
Do not assume a battery from one brand fits another brand’s mower. The EGO listings say the mower works with EGO 56V ARC Lithium batteries, and the Greenworks listing says 75+ compatible tools. Check the manufacturer’s compatibility list before you buy a second battery or a tool that claims to share one.
Disconnect the battery before any blade work, store and charge it as the manual says, and do not try to repair a battery pack yourself. If a pack is damaged, follow the manufacturer’s instructions.
Who should buy a self-propelled mower, and who should skip it
Buy one if pushing a mower is the problem, especially on uneven or sloped ground, or if you want a battery mower and the listing includes the battery and charger.
Skip it if your lawn is small and flat and a light push mower does the job. Skip it if you want a machine that runs without an operator; that is a robotic mower. And skip it if you cannot confirm from the listing that the mower takes the battery you already own.
Checklist before you buy
- Confirm the drive in at least two places: the title and the bullets. If Operation Mode says Manual, check the manual.
- Count the batteries and the charger in the box, and check whether a second battery is extra.
- Write down the battery voltage and amp-hours from the listing. Do not assume they match another brand.
- Match the cutting width to your lawn. The group runs from 20 to 24 inches.
- Treat runtime as a claim. Ask the seller for test conditions if they are not on the page.
- Check the weight against how you will move the mower.
Safety notes for self-propelled mowers
Keep hands and feet away from the blade while the mower runs. Learn where the drive engage control and speed dial are before your first mow, and read the owner’s manual for how to stop the drive quickly.

Frequently asked questions
Does “lawn mower that goes by itself” mean a robotic mower?
Usually not. A self-propelled mower drives its own wheels, but you still start it, steer it and stop it. A robotic mower has no operator and runs on its own schedule.
How can I tell from a listing that a mower is self-propelled?
Look for “Self-Propelled” in the title or the Style field, then check the bullets. Some listings show Operation Mode as Manual even when the title says self-propelled, so confirm the drive in the manual before you buy.
Do these mowers come with a battery?
Five of the seven listings state that a battery is included, and four of those also state a charger. The EGO LM2130SP ships without either, and the Ryobi listing does not state what is in the box.
Can I use a battery from another brand?
Do not assume so. Check the manufacturer’s compatibility list. The EGO listings say compatible with EGO 56V ARC Lithium batteries, and the Greenworks listing says 75+ compatible tools.
Which listing has the longest runtime claim?
The Greenworks 82V 21 inch listing claims up to 90 minutes, and the EGO LM2135SP claims up to 60 minutes on its included battery. Both are listing claims, and real runtime varies with grass and terrain.
Conclusion: the decision rule
If you want a drive without a robot, buy a self-propelled model whose listing names the battery and charger in the box. If the listing does not say what is included, confirm it before you order. If you want a mower that runs with no one at the controls, a self-propelled model is the wrong choice; look at robotic mowers instead.
