The Greenworks 80V 21 in Mower/Blower/Trimmer Kit is a comprehensive cordless solution for homeowners with small to medium-sized lawns who want to ditch gas and oil. It bundles a 21-inch push mower, a 13-inch string trimmer, and a blower, all powered by the same 80V battery platform. The primary draw is convenience: one battery system for three essential yard tasks, backed by a brushless motor for efficiency and a 4-year warranty for peace of mind.

The centerpiece is the 21-inch steel deck mower, which offers a 3-in-1 system for mulching, rear bagging, or side discharge. This flexibility lets you adapt to seasonal lawn conditions: mulch in fall for nutrients, bag in spring for a clean cut, or side discharge for tall grass. The 7-position height adjustment allows precise cutting from 1.5 to 4 inches, accommodating different grass types and preferences. The brushless motor is a key upgrade over brushed motors, providing more torque, longer runtime, and less maintenance over time.

Included in the kit are two 2.0 Ah batteries and a 4A rapid charger, which reduces downtime between charges. The mower features LED headlights for low-light mowing, a practical touch for early mornings or evenings. The trimmer has a variable speed trigger for precise control, and the blower handles leaves and clippings efficiently. The hand-push design is lighter than self-propelled models, and vertical storage saves valuable shed space.

However, the 2.0 Ah batteries are on the smaller side. On a typical quarter-acre lot, you may need to recharge mid-mow, especially if using the trimmer and blower in the same session. The hand-push mower requires more physical effort on slopes or uneven ground, so those with hilly terrain might prefer a self-propelled model. Also, battery-powered mowers generally have less raw cutting power than gas mowers, so thick, wet grass may require slower passes or a higher cut setting.

Overall, this kit is a strong value for homeowners with small to medium flat lawns who want a cordless, low-maintenance system. The main reason to buy is the convenience of a single battery platform for mowing, trimming, and blowing. The main reason to hesitate is if you have a large lawn or steep terrain, where you might need larger batteries or a self-propelled mower. For those users, a gas mower or a robot mower could be a better fit.

80V Brushless Motor: The brushless motor delivers efficient power, meaning more of the battery's energy goes into cutting rather than being wasted as heat. This translates to longer runtime and a longer motor lifespan. It's especially beneficial for regular mowing on medium lawns where consistent power is needed.

3-in-1 Cutting System: The mower offers mulching, rear bagging, and side discharge. Mulching returns nutrients to the soil, reducing the need for fertilizer. Bagging gives a clean, manicured look and is useful for collecting leaves. Side discharge is best for tall grass when you're in a hurry. This flexibility lets you adapt to seasonal needs.

2x2.0 Ah Batteries with 4A Rapid Charger: Two batteries mean you can keep one charging while the other is in use, effectively doubling your runtime. The 4A rapid charger significantly reduces charge time compared to standard chargers, getting you back to work faster. This is ideal for small to medium lawns where one battery may not suffice.

7-Position Height Adjustment: With seven cutting heights, you can fine-tune the mower to suit your grass type and season. Cutting too low can stress grass, while cutting too high can leave it looking shaggy. This adjustability helps maintain a healthy lawn and a neat appearance.

LED Headlights: Built-in LED lights illuminate your path when mowing in low-light conditions, such as early morning or evening. This is a safety feature that also extends your usable mowing time, especially during shorter fall days.

Best For: This kit is ideal for homeowners with small to medium-sized flat lawns (typically up to 1/4 acre) who want a cordless, low-maintenance alternative to gas equipment. It's also great for those who value convenience and having all tools from one brand, simplifying battery compatibility and charging.

Consider Alternatives If: If your lawn is larger than 1/4 acre, the 2.0 Ah batteries may not provide enough runtime for a single mowing session. In that case, look for kits with larger batteries (like 4.0 Ah or higher) or consider a self-propelled mower if your terrain is hilly or uneven. Gas mowers might still be preferable for very thick or wet grass.

Setup and Daily Use: The kit arrives mostly assembled; you'll need to attach the handles and trimmer guard. Daily use is straightforward: charge the batteries, insert one into the mower, and mow. The push design is easy to maneuver on flat ground. The trimmer and blower are ready to go with the same battery type, so you can switch between tools without swapping chargers.

Maintenance Requirements: Battery-powered tools require minimal maintenance compared to gas. You'll need to sharpen the mower blade periodically (about once a season) and clean the deck after each use to prevent grass buildup. Store batteries in a cool, dry place and avoid leaving them in extreme heat. The brushless motor requires no oil changes or filter replacements, saving time and money.

What Sets It Apart: The 80V platform is a step up from typical 40V systems, offering more power and efficiency. The inclusion of a trimmer and blower in one kit provides excellent value, eliminating the need to buy separate tools. The 4-year warranty is also more generous than many competitors, offering peace of mind.

Mowing Performance: The 21-inch steel deck is a good size for residential lots, covering a decent swath per pass. The brushless motor provides steady power for normal grass conditions. The 3-in-1 system allows you to choose between mulching, bagging, or side discharge, letting you adapt to the season. For best results, mow when the grass is dry and avoid cutting more than one-third of the blade height at a time.

Trimming: The 13-inch string trimmer is suitable for edging along fences, flower beds, and driveways. The variable speed trigger gives you control to handle light weeds or heavier growth. It's lightweight and easy to handle, making it a practical companion to the mower for finishing touches.

Blowing: The blower is effective for clearing leaves, grass clippings, and debris from driveways, patios, and sidewalks. It's a handy tool for post-mowing cleanup, and its cordless design means no tangled extension cords.

Runtime Realities: With two 2.0 Ah batteries, you can expect roughly 30-45 minutes of mowing per battery, depending on grass conditions. For a small lawn, that's often enough to finish. For larger areas, you'll need to swap batteries mid-mow. The 4A rapid charger can recharge a battery in about 30-40 minutes, so downtime is manageable.

Terrain Handling: The hand-push design works well on flat, even ground. On slopes, you'll need to exert more effort to push the mower uphill. For hilly properties, a self-propelled model would be more comfortable. The mower's wheels are designed for standard residential lawns, not rough or rocky terrain.
