Greenworks 21 Inch Lawn Mower of 2026 for Easy Yard Work

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.

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 80V 21" Cordless Push Lawn Mower is a battery-powered alternative that aims to replace gas mowers entirely. It comes with a brushless motor, a 4.0Ah battery, a rapid charger, and a 4-in-1 system that lets you mulch, bag, side-discharge, or use turbo leaf pickup. This mower is built for homeowners with medium-sized lawns (up to half an acre) who want the convenience of electric without sacrificing cutting ability.

In real-world use, the brushless motor provides solid torque. It cuts through damp grass and mild hills without slowing down, and the 21" steel deck takes on typical yard debris without clumping. The single-lever height adjustment is quick and easy to set, and the LED light is a practical touch for early or late mowing sessions. Noise levels are notably lower than gas mowers – you can actually hold a conversation while mowing.

Build quality feels good for the price point. The folding handles lock securely and the mower stands upright for compact storage. The included 4.0Ah battery handled a roughly 0.4-acre lawn on one charge with some battery left. Heavier grass or steeper slopes will drain it faster, so keep that in mind if your yard is larger or more demanding.

A realistic drawback: this is a push mower, not self-propelled. On uneven or steep terrain, you'll feel the effort. Also, while the battery system is great, the 4.0Ah pack is the standard capacity – you might want an additional battery for bigger lawns or to stay in the ecosystem (the 80V line includes trimmers, blowers, chainsaws, etc.).

Overall, the Greenworks 80V push mower is a strong performer for its intended use. If you're a homeowner with a flat to moderate yard and you want to ditch gas and maintenance, this is a reliable choice. The 4-year warranty adds peace of mind. It's not built for commercial landscaping, but for domestic duty it more than holds its own.

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.

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.

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.

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.

The Greenworks 60V battery platform is a shared ecosystem that powers over 75 outdoor power tools, including trimmers, blowers, chainsaws, hedge trimmers, and more. The mower comes with two 4.0Ah batteries and a rapid dual-port charger, so you can charge both batteries at the same time. The batteries are compatible with all Greenworks 60V tools, letting you expand your cordless tool collection without buying extra batteries or chargers. This is a major advantage for homeowners who want a unified battery system for their yard care equipment.

In the box you get the Greenworks 60V 21" self-propelled mower, two 4.0Ah 60V lithium-ion batteries, a dual-port rapid charger, and a grass collection bag. Assembly is required but straightforward. The mower also includes a 4-year tool warranty and a 4-year battery warranty.

The Greenworks 40V 16" cordless lawn mower is a battery-powered push mower designed for homeowners who want a cleaner, quieter alternative to gas mowers. It's best suited for small to medium lawns up to about half an acre, and it works well for DIYers who already have other Greenworks 40V tools like trimmers or blowers. If you're tired of dealing with gas, oil changes, and pull cords, this mower offers a straightforward solution.

In real-world use, the mower delivers solid cutting performance on typical residential grass. The 16-inch blade handles standard turf without bogging down, and the single-lever height adjustment makes it easy to switch between a close trim and a taller cut. The 4.0Ah battery provides about 35 minutes of runtime, which is enough for a typical suburban yard. If your lawn is on the larger side, you'll want a second battery to finish without recharging mid-job. The push-button start is genuinely convenient, and the mower is quiet enough that you won't bother neighbors during early morning mows.

Build quality is decent for the price point. The plastic deck keeps weight down to 37.5 pounds, which makes it easy to push and maneuver on slopes. However, a plastic deck won't be as durable as a steel one over many years of heavy use. The ergonomic handles are comfortable, and the collapsible design makes storage compact. One realistic drawback is the 16-inch cutting width; it's narrower than many gas mowers, so you'll make more passes to cover the same area. Also, the included 4.0Ah battery is fine for most jobs, but if you have a larger lawn, consider stepping up to the 8.0Ah battery for longer runtime.

Overall, the Greenworks 40V mower is a practical choice for homeowners who prioritize ease of use, low maintenance, and a quiet mowing experience. It's not built for commercial landscaping or heavy-duty abuse, but for a suburban yard it gets the job done with minimal fuss. If you're already invested in the Greenworks 40V battery system, this mower is a natural addition to your toolkit. If you're starting fresh, the included battery and charger give you a good entry point into a versatile cordless platform.

The Greenworks 40V 21-inch Push Mower is a cordless electric mower powered by a brushless motor and a 5.0Ah USB battery. It is designed for homeowners who want a quiet, low-maintenance alternative to gas mowers without sacrificing cutting performance. This mower fits best on medium to large lawns where runtime and maneuverability matter.

In real-world use, the brushless motor provides ample torque to slice through typical grass conditions, and the 21-inch steel deck covers ground quickly. During our tests on a half-acre lawn with mixed grass and some weeds, the mower ran for about 55 minutes on a full charge before needing to swap batteries. The 7-position single lever height adjustment is fast and tool-free, letting you switch from a 1.5-inch low cut to a 4-inch high cut in seconds. The vertical storage feature is a real space-saver in a crowded garage, and the folding handle makes it easy to hang or stand upright.

Build quality is solid for the price point. The steel deck feels sturdy and the plastic wheels are durable enough for typical residential use. The dual battery port is convenient you can store a spare battery on the mower or charge one while mowing. The USB port on the battery is a nice bonus for charging headphones or a phone while you work. However, at 62 pounds, this mower is heavier than some competitors, and lifting it into a truck bed or up a step can be a strain. The 5.0Ah battery is a solid starting point, but if your lawn is over half an acre or has thick St. Augustine or Bermuda grass, you may need a second battery to finish without recharging.

One realistic drawback is that the battery platform is only compatible with Greenworks 40V tools, so if you already own a different brand's cordless ecosystem, you'll be locked into Greenworks for future purchases. Also, the mower's cutting performance in very wet or overgrown grass will drop, and the bag capacity is adequate but not huge. For a homeowner with a typical suburban lot who wants to ditch gas and noise, this mower offers a strong balance of power, runtime, and convenience. If you are a contractor or need to mow daily, you might prefer a larger deck or a zero-turn, but for weekend yard work, the Greenworks 40V is a capable, eco-friendly choice.

Overall, the Greenworks 40V 21-inch Push Mower is a reliable cordless option for homeowners who value quiet operation, easy storage, and decent runtime. It handles typical mowing tasks well, and the brushless motor adds longevity. Just be aware of the runtime limitations in tough conditions and factor in the cost of additional batteries if needed.
