Best Greenworks 60V 21in Self-Propelled Lawn Mower
As an Amazon Associate we earn from qualifying purchases.
If you are looking for the best Greenworks 60V 21in Self-Propelled Lawn Mower for a medium or large yard, the stored listing gives you the core facts: a 60V battery platform, two 4.0Ah batteries in the kit, rear-wheel drive, a cutting width of 20.28 inches (the title says 21in), and a cutting height range of 1 to 4 inches. The listing does not say whether a charger is included. It gives no runtime in minutes, only a coverage claim of up to 3/4 acre per charge. This guide sorts what the listing states from what it leaves open.
Quick answer
- The listing states a 60V battery platform with a brushless motor and two 4.0Ah batteries, and it describes the mower as self-propelled with rear-wheel drive traction.
- Cutting width is the figure to confirm. The spec field says 20.28 inches and the title says 21in, and the listing does not explain the difference.
- The stored listing does not say whether a charger is included, so check the live listing for the charger line before you order.
- Buy this mower when its stated width, height range and 60V platform fit your yard and you either own a Greenworks 60V charger or the listing confirms one is in the box.

Who it suits
This mower suits an owner who wants a battery mower with a self-propelled drive for a yard large enough that the cutting width matters. The listing describes the drive as rear-wheel drive traction for tackling slopes and thick grass, so the feature points toward lawns with uneven ground or heavy growth. The listing does not compare the drive with a push model, so any advantage over a push mower is your judgment, not a stated figure.
Owners who already use Greenworks 60V batteries
The listing says the mower works with 75 or more Greenworks 60V tools, including trimmers, blowers and chainsaws. If you already own 60V batteries and a charger from the same line, the platform fits your existing kit. The listing does not say whether batteries from other Greenworks platforms can be swapped in, so do not assume it.
Yard size and the pass arithmetic
The width you need depends on the size of the lawn. This arithmetic uses only the stated cutting width. Divide the width in inches by 12 to get feet, multiply by the length of a straight pass to get the area of one pass, and divide the lawn area by that figure to estimate the passes needed.
| Step | Using 20.28 inches (spec field) | Using 21 inches (title) |
|---|---|---|
| Width in feet (inches divided by 12) | 1.69 ft | 1.75 ft |
| Area of one 100 ft straight pass (width times 100) | 169 sq ft | 175 sq ft |
| Passes to cover 3/4 acre (32,670 sq ft divided by area per pass) | about 193 | about 187 |
One acre is 43,560 square feet, so three quarters of an acre is 32,670 square feet. The result is a count of straight 100-foot passes needed to cover that area once. It ignores overlap between passes, turns at the ends of rows, and the time each pass takes. It is not a runtime estimate, and the listing does not state a travel speed.
The same arithmetic works for smaller lawns. The table uses the two widths the listing gives and three common lawn sizes, with each count rounded to the nearest whole pass.
| Lawn size | Area (sq ft) | Passes at 20.28 inches | Passes at 21 inches |
|---|---|---|---|
| 1/4 acre | 10,890 | about 64 | about 62 |
| 1/2 acre | 21,780 | about 129 | about 124 |
| 3/4 acre | 32,670 | about 193 | about 187 |
Each count assumes straight passes that do not overlap. A real lawn with overlap, edges and obstacles needs more passes. The gap between the two widths is small: at a quarter acre the counts differ by about two passes, and at three quarters of an acre by about six. For buying purposes, the width discrepancy matters less than whether the lawn needs the 1 to 4 inch height range and a battery platform you already own.
Cutting height
The listing gives a minimum of 1 inch, a maximum of 4 inches and 7 positions. It does not say how those positions are spaced. If they are evenly spaced, the steps are 0.5 inch apart: 1, 1.5, 2, 2.5, 3, 3.5 and 4 inches. Confirm the actual settings in the manual if one specific height matters for your grass.
Before you buy
- Confirm the charger line on the live listing. The stored text does not state one.
- Check which cutting width the seller shows, 20.28 inches or 21in, and use the matching column in the pass tables.
- Compare your gate width and storage space with the listed overall dimensions of 68.89 by 25.63 by 42.12 inches.
- Decide which height you want from the 1 to 4 inch range, then confirm the exact settings in the owner’s manual, since the listing does not give the spacing.
- Look up the full warranty terms on the manufacturer’s site, because the listing gives only the summary wording.
Safe use before the first mow
The safety rules here come from the Ohio State factsheets, not from the listing. Three points matter most for a self-propelled model. First, do not disable safety features such as auto-clutches and shut-off switches, and keep hands and feet away from the mowing deck, blades and moving parts. Second, operate the unit only on stable ground or footing, to avoid potential slips and falls, and run self-propelled mowers only at safe travel speeds. Third, clear the area before starting, because foreign objects can fly from the mower.
The factsheet on power lawn mowers says to mow across the slope with a push mower. The listing describes this model as self-propelled and gives no slope rule, so follow the owner’s manual for slopes. Keep bystanders at least 50 feet away, do not allow riders, and never use an electric mower on wet grass. The same factsheet says to maintain cutting edges on the blades. The listing does not describe blade care for this model, so the manual is the place to check it.
Skip it if
- You need a charger in the box and the listing does not confirm one. The kit is described as two 4.0Ah batteries, and the stated listing text does not mention a charger.
- You lift the mower often. The listing gives its weight as 65 pounds, about 29.5 kilograms, which is a real load to carry into a truck bed or onto a storage shelf.
- You need a cut below 1 inch or above 4 inches. The listing sets the range at 1 to 4 inches, and no wider range is stated.
- Your lawn is mostly rough ground or brush. The Ohio State factsheet says power lawn mowers are not designed for use on rough or brush-covered terrain. The listing does not describe other ground types, so the mower’s fit there is unknown.
- You would rather have a machine with no battery to charge. Our guide to self-propelled corded electric lawn mowers covers that route.
What the listing does not say
These gaps change the buying decision, so each one is named here.
Battery and charger
The listing names the kit as (2) 4.0 Ah Battery Kit and describes the platform as 60V with two 4.0Ah batteries. It does not say whether a charger is in the box. The spec field labeled Number of Items reads 2, but the listing does not say what the two items are. Read the live listing’s item list before you order. If battery voltage and amp-hours are new terms for you, see our guide to lawn mower battery voltage and amps.
Runtime
The listing gives no runtime in minutes. Its only run-time figure is a coverage claim: up to 3/4 acre per charge, with performance that varies by terrain and technique. The listing does not say what grass height, cutting speed or deck setting the claim assumes. Treat it as the seller’s statement, not as a result that applies to your yard.
Missing details
- Blade type and blade count.
- Bag capacity, and whether a bag comes with the mower.
- Travel speed of the self-propelled drive.
- Which parts are plastic. The material field says only “Plastic”.
- The warranty terms behind the “4-year limited tool and battery warranty” wording.
How we chose
This post covers one product: the Greenworks 60V 21in Self-Propelled Lawn Mower, ASIN B09SY912MK, model MO60L424. It was assigned to this keyword because its title matches the search closely. The listing data in this post comes from a stored scan dated 2026-10-11, the date the record was last checked. That stored scan is the only source for the model’s listed specifications.
The criteria were the ones a reader can check against the listing: battery platform, battery pack, drive type, cutting width, height range, weight, dimensions and warranty. Price, ratings and sales badges were left out. We did not rank this mower against others, and we did not compare brands. Two Ohio State University Extension factsheets, opened on 2026-10-22, supply the general safety points.
What we could not verify
- Runtime in minutes, and whether the 3/4 acre per charge claim holds for your grass, slope or cutting height. The listing gives no conditions.
- Whether a charger comes with the mower.
- Which cutting width is correct for this model: the spec field says 20.28 inches and the title says 21in.
- Blade type, bag capacity and travel speed.
- The manufacturer’s own product page and owner’s manual for model MO60L424. Neither was opened for this draft, so the listing is the only source for the model’s stated facts.
- Any performance on steep slopes beyond the listing’s own wording about slopes and thick grass.
FAQ
Does the Greenworks 60V 21in self-propelled mower come with a charger?
The stored listing does not say whether a charger is included. It describes the kit as two 4.0Ah batteries. Check the live listing before you order.
How wide does this mower cut?
The spec field says 20.28 inches and the title says 21in. The listing does not explain the gap, so both figures appear in the table above and in the pass arithmetic.
What cutting heights does it offer?
The listing gives a minimum of 1 inch and a maximum of 4 inches, with 7 positions. It does not say how the positions are spaced. If they are evenly spaced, the steps are 0.5 inch apart.
Does it mulch, bag and discharge leaves?
The listing says the mower has a 4-in-1 system: mulch, bag, side discharge and turbo leaf pickup. It does not give the bag capacity, so check that figure before you plan leaf work.
What safety rules apply to a self-propelled mower?
Ohio State University Extension advises taking self-propelled mowers out of gear before starting, carrying no extra riders, and keeping bystanders at least 50 feet away. Remove litter and debris from the mowing area first, because thrown objects can be dangerous.
Is a 60V battery mower enough for a large lawn?
The listing says the mower covers up to 3/4 acre per charge, but it does not say which conditions the claim assumes or how long a charge lasts in minutes. The pass arithmetic above shows how many straight passes a 3/4 acre area needs at the stated width. Use the coverage claim as a starting point, not a guarantee.
Bottom line
Buy this mower only when its stated 60V platform, 1 to 4 inch height range and cutting width fit your lawn, and when you already own a Greenworks 60V charger or the live listing confirms that one is in the box.
