Its brushless motor and 21-inch steel deck handle thick grass and uneven terrain with ease, while the included 4.0Ah battery covers up to half an acre per charge.
Pros & Cons

Pros

  • Powerful brushless motor tackles tall or damp grass with the turbo mode
  • Self-propelled drive reduces effort on hills and during long mowing sessions
  • Battery life is solid for up to half an acre on a single charge with reasonable grass conditions
  • Tools-free folding handles and steel deck feel durable and well-built for regular use

Cons

  • Backing up can be tricky the mower's drive system takes a moment to disengage, requiring a slight pause
  • Included 4.0Ah battery may not suffice for larger yards over half an acre without a second battery or intermediate charge
  • Bag capacity is on the smaller side, requiring more frequent emptying when bagging heavy or wet grass
Detailed Review

The Greenworks 80V 21-inch Self-Propelled Cordless Lawn Mower is a battery-powered walk-behind mower built for homeowners who want gas-level performance without the hassle of fuel, oil changes, or loud engines. It is best suited for anyone maintaining a quarter- to half-acre yard, especially if you are tired of pulling cords or dealing with maintenance on a gas mower. It also works well for DIYers who already own Greenworks 80V tools, since the batteries are interchangeable across a wide ecosystem.

In real-world use, the brushless motor provides noticeable torque. It powers through thick, overgrown grass and even light weeds without stalling, especially when you engage the turbo leaf pickup setting. The self-propelled drive with rear-wheel traction handles slopes confidently, and the variable speed lets you match your walking pace. Most users report mowing their entire front or back yard on a single charge of the included 4.0Ah battery, though taller or wet grass may cut that range short. The 7-position single-lever height adjustment makes switching between grass types or seasonal growth quick and simple.

Build quality is solid for a cordless mower. The 21-inch steel deck resists rust and holds up to bumps against rocks or curbs. The folding handle makes storage compact, and you can stand it upright to save space in a shed or garage corner. Assembly out of the box is minimal, usually just attaching the control bar. The foam grip on the handle is comfortable but some reviewers note it may wear over time with heavy use. The mower is significantly quieter than any gas model, which is a big plus for early morning or evening mowing in tight neighborhoods.

There are a few realistic drawbacks to consider. The self-propelled system takes a moment to disengage, so backing up requires a brief pause before the wheels roll freely. This is a common trait among many rear-wheel drive electric mowers. The bag capacity is on the smaller side, so you may need to empty it more often during heavy mulching or when bagging lush grass. And while the 4.0Ah battery covers most medium-sized yards, anyone with over half an acre should probably invest in a second battery for uninterrupted work.

Overall, the Greenworks 80V self-propelled mower offers excellent value for anyone looking to switch from gas to cordless. It combines genuine cutting power, easy maintenance, and a versatile battery system that extends beyond just mowing. If you have a quarter-acre to half-acre yard and want a reliable, quiet, and fuss-free machine, this mower is a smart buy. For larger properties, consider stepping up to a bigger battery or a riding mower, but for most homeowners this one gets the job done right.

Battery Platform

The Greenworks 80V battery system powers over 75 compatible tools, including string trimmers, leaf blowers, chainsaws, hedge trimmers, snow blowers, and more. The included 4.0Ah lithium-ion battery charges fully in about 60 minutes with the rapid charger. When used for mowing, a full charge handles up to half an acre under normal conditions. The 80V platform is a good choice for homeowners who want to consolidate their yard gear into one battery ecosystem, saving money over time by avoiding duplicate purchases.

For larger yards, Greenworks offers higher-capacity batteries like the 5.0Ah and 8.0Ah packs, both compatible with the mower. The batteries feature a fuel-gauge style indicator that shows remaining charge at a glance. They also have a low self-discharge rate, so they hold their charge well over winter storage. It is worth noting that the 4.0Ah battery is on the lighter side, which helps keep the mower manageable, but if you have over half an acre you will likely want a second battery for extended runtime.

The Greenworks 60V 21 inch cordless lawn mower delivers gas-level power with 3200 RPM and 50% more torque than 40V models, making it a solid choice for homeowners with up to half-acre lawns. It offers zero emissions, quiet operation, and minimal maintenance, ideal for eco-conscious users who want a hassle-free mowing experience.
Pros & Cons

Pros

  • Excellent runtime and quick 50-minute recharge keep you moving through a typical lawn mowing session.
  • SmartCut blades deliver consistent cut quality even in thick or damp grass, reducing the need to slow down.
  • LED lights and easy-push design with large wheels make mowing convenient at any time of day.
  • Rugged steel deck and IPX4 rating offer durability in real-world conditions.

Cons

  • It's a push mower, not self-propelled, so you'll need to supply the effort on slopes or large yards.
  • The included 5.0Ah battery is good for one full mow on half an acre; a second battery adds cost but enables continuous use.
  • Assembly is required, though the process is straightforward and takes about 15-20 minutes.
Detailed Review

The Greenworks 60V 21 inch cordless lawn mower is a battery-powered push mower designed to replace a gas mower for residential lawns up to about half an acre. It runs on Greenworks' 60V lithium-ion platform and comes with a 5.0Ah battery and rapid charger. The mower is built for homeowners who want gas-level cutting performance without the noise, fumes, and maintenance of a traditional gas engine.

In real-world use, this mower delivers impressive power. The brushless motor spins the blade at 3200 RPM, which is comparable to a 150cc gas mower. It also provides 50% more torque than typical 40V cordless mowers, so it can handle thicker, wetter grass without stalling. The SmartCut self-sharpening dual blades automatically adjust power to prevent bogging down, and the 4-in-1 system lets you mulch, bag, side-discharge, or use turbo mode for leaf pickup. The 60-minute runtime on a single 5.0Ah battery is realistic for a standard lawn, and the rapid charger refills the battery in about 50 minutes. If you have a larger yard, you can add a second battery for continuous mowing.

Build quality is solid. The steel deck is durable and rust-resistant, and the IPX4 waterproof rating means you can mow in light rain or wet grass without worry. The 10-inch rear wheels and 8-inch front tires roll smoothly over uneven ground. LED headlights are a nice touch for mowing early or late in the day. The single-lever height adjustment offers seven positions, making it easy to set the cut height for different grass types. The mower is relatively easy to push on flat or gently sloping ground, but it is not self-propelled, so you will need to exert effort on hills or heavy grass.

One limitation is the lack of self-propulsion. For large or sloped yards, you might want a self-propelled model. The included 5.0Ah battery covers about half an acre, so users with larger lawns will need to buy an extra battery or be okay with recharging mid-job. Assembly is required, but it takes only about 15 to 20 minutes with basic tools. The mower is also compatible with over 75 Greenworks 60V tools, which is great if you already have or plan to expand your cordless outdoor toolkit.

Overall, the Greenworks 60V 21 inch cordless push mower is a strong choice for homeowners who want gas-level mowing power without the upkeep. It performs well on moderate-sized lawns, handles tough grass conditions, and offers thoughtful features like LED lights and SmartCut blades. If you prioritize a lower price point or need self-propulsion, you may want to look elsewhere, but for a reliable, quiet, and eco-friendly mower, this model delivers excellent value.

Battery Platform

This mower uses Greenworks' 60V lithium-ion battery platform. The included 5.0Ah battery provides 270 watt-hours of energy and charges fully in about 50 minutes with the included rapid charger. The battery is compatible with all Greenworks 60V tools, including trimmers, blowers, chainsaws, and more. You can purchase additional 60V batteries in 2.0Ah, 4.0Ah, 5.0Ah, or 8.0Ah capacities to extend runtime or power other tools.

One key feature is the dual-port auto-switch system, which allows the mower to seamlessly switch to a second battery when the first runs out, keeping you mowing without interruption. This is especially useful for larger lawns. The batteries are weather-resistant and designed for outdoor use.

Best Use Cases

This mower is best suited for homeowners with flat to gently sloping lawns up to about half an acre. It excels in situations where you want a quiet, emission-free mowing experience and don't want to deal with gas, oil, or spark plugs. The LED lights make it a great choice for mowing in the early morning or late evening. The 4-in-1 capability means it can handle mulching, bagging, side-discharging, and leaf pickup, so it's versatile across seasonal needs. If you value a low-maintenance tool that's part of a larger cordless system, this mower fits well. However, if you have a large, hilly property or need self-propulsion, consider a self-propelled model or a gas mower.

Detailed Review

The Greenworks 60V 21" Self-Propelled Cordless Lawn Mower is a battery-powered walk-behind mower designed for homeowners who want gas-level performance without the noise, fumes, and maintenance of a traditional gas engine. It uses a brushless motor spinning at 3200 RPM, dual 4.0Ah batteries, and a self-propelled rear-wheel drive system to make mowing easier and more eco-friendly. This mower is best suited for homeowners with medium to large lawns (up to 3/4 acre) who are already invested in the Greenworks 60V ecosystem or want a reliable cordless mower that can handle slopes, thick grass, and varied cutting conditions.

In real-world use, the mower delivers strong cutting power. It cuts through tall, thick grass without bogging down, and the 7-position height adjustment is quick and simple to change with one lever. The self-propelled system is adjustable on the fly, letting you match your walking pace. The included two 4.0Ah batteries provide about 45-60 minutes of runtime depending on grass conditions, and the automatic battery swap keeps you mowing without interruption. The LED headlights are bright enough for mowing in low light, and the 4-in-1 system (mulch, bag, side discharge, turbo leaf pickup) offers flexibility. The grass bag is durable and fills from the back forward, so you don't have to constantly shake it.

Build quality is solid. The aluminum handles are rust-proof, the deck is IPX4 waterproof, and the mower feels well put together. At 65 pounds with batteries, it's not the lightest, but the self-propelled drive makes it easy to maneuver. The EZ Fold handles collapse vertically for compact storage. One minor drawback is that the self-propelled speed adjustment can be a bit finicky to find the perfect setting, and the automatic battery swap occasionally hesitates for a moment before switching. Also, the suction for leaf pickup is weaker than a gas mower, so fall cleanup may require a second pass or a dedicated blower.

Overall, the Greenworks 60V 21" mower is a strong choice for homeowners who want a quiet, clean, and powerful cordless mower. It's especially cost-effective if you already own other Greenworks 60V tools, since the batteries are interchangeable. For the price, you get a well-rounded mower with dual batteries, a fast charger, and features that make lawn care less of a chore. If you have a large lawn or need maximum leaf suction, you might want to supplement with a gas mower or a leaf blower, but for most suburban yards, this mower will handle the job with ease.

Frequently Asked Questions

Do these mowers work on steep slopes?

Yes, the self-propelled models use rear-wheel drive for better traction. This helps maintain control on inclines without slipping. The variable speed control allows you to adjust pace safely. Many property owners find this drive system easier on steep yards.

How long does the battery last per charge?

Runtime varies by grass density and operator speed. The 4.0Ah battery handles up to half an acre. The 5.0Ah option offers extended time for larger areas. Some buyers find that dual-battery setups prevent mid-mow stops.

Most models are built to handle damp conditions. The steel deck resists rust better than aluminum. It is designed for tough, wet grass environments. This durability supports long-term use in high-moisture areas.

Can I use these with other Greenworks tools?

Yes, they are compatible with 75+ other tools. This ecosystem saves money on future equipment purchases. You can share batteries across your yard toolkit. This flexibility is a key benefit for eco-conscious buyers.
