Greenworks 80V 21″ Brushless Cordless Lawn Mower Review: A Long-Term User’s Perspective

For years, I wrestled with the limitations of a gas-powered lawn mower. The constant pulling of the cord, the smell of fumes, the noise pollution – it was all incredibly tiresome. I knew there had to be a better way, a more efficient and environmentally friendly solution. A Greenworks 80V 21″ Brushless Cordless Lawn Mower would have been a lifesaver back then; it would have saved me from the struggles of unreliable starting, messy oil changes, and the sheer physical effort required.

Factors to Ponder Before Purchasing a Cordless Lawn Mower

Choosing a cordless lawn mower is a significant decision, particularly if you’re replacing a gas model. Cordless mowers offer the benefit of quiet operation, reduced emissions, and the convenience of eliminating gas and oil maintenance. However, it’s crucial to consider your yard’s size and the terrain. If you have a large yard with significant inclines or uneven ground, a more powerful machine might be necessary. For smaller, relatively flat lawns, a Greenworks 80V 21” cordless mower like this one is a great choice. You should also consider battery life and charging time, ensuring the mower’s capacity aligns with your yard’s size. Lastly, think about the features that matter most to you—mulching capabilities, bagging options, and height adjustment settings – before making your purchase. For those with extremely large properties or particularly challenging terrain, a riding mower or a more robust, gas-powered model might still be a better fit.

* Cons: Can struggle with extremely tall or wet grass, battery life can be reduced in challenging conditions, may require multiple charges for very large yards.

A Deep Dive into the Features and Benefits

The Brushless Motor: A Powerhouse of Efficiency

The heart of this mower is its brushless motor. This isn’t just marketing hype; it’s a significant upgrade. The brushless motor provides noticeably more power than brushed motors found in many cheaper models. This translates to a clean, even cut, even in thicker grass. Moreover, the brushless motor’s efficiency results in extended battery life and quieter operation compared to brushed models. The quiet operation is a game-changer, especially for those living in densely populated areas.

Battery Life and Charging Time: Power When You Need It

The 4.0Ah battery provides a runtime of up to 60 minutes, depending on grass conditions and usage. In my experience, this was more than enough for a single mowing session of my medium-sized lawn. The rapid charger ensures a relatively quick recharge time, minimizing downtime between mowing sessions. While the 60-minute runtime might seem short compared to a gas mower’s tank, it’s important to consider the convenience of not having to deal with gas and oil. In my experience, owning a second battery alleviates any worry about runtime completely.

Cutting Deck and Height Adjustment: Precision Cutting Made Easy

The 21-inch cutting deck is wide enough to cover a good amount of ground efficiently, while still remaining maneuverable in tight spaces. The seven-position height adjustment allows for precise cutting to match various grass types and preferences. This single-lever adjustment mechanism is intuitive and simple to use.

3-in-1 Versatility: Mulch, Bag, or Side Discharge

The 3-in-1 system offers versatility in how you handle clippings. Mulching returns nutrients to the soil, while bagging is ideal for neater results or when collecting clippings is necessary. Side discharge provides a quick solution, particularly for larger areas or when the grass is extremely tall. This feature has proven incredibly convenient in adapting to changing yard conditions.

Ergonomics and Ease of Use: A Pleasant Mowing Experience

The Greenworks 80V mower is designed with comfort and ease of use in mind. The foldable handle makes storage a breeze, while the intuitive controls simplify operation. The lightweight design reduces strain during extended use.

Gathering User Feedback: Real-World Experiences

Numerous online reviews echo my positive experiences. Users praise the mower’s quiet operation, ease of use, and the power of the brushless motor. Many highlight its performance in various grass types and its efficiency in terms of both time and effort saved. A common thread among positive reviews is the surprising power and ease of use of the Greenworks 80V 21″ cordless lawnmower even for people who have never used a cordless lawnmower before. Several reviews do mention the occasional struggle with extremely tall, wet grass. However, this issue seems to be manageable through adjustments in mowing technique.

Final Verdict: A Sound Investment for a Healthy, Green Lawn

The challenges of maintaining a healthy lawn are numerous; dealing with gas-powered mowers exacerbates them. The Greenworks 80V 21″ Brushless Cordless Lawn Mower offers a superior alternative by addressing these issues head-on. Its quiet operation, powerful performance, and ease of use are compelling reasons to choose it. It saves time, reduces effort, and promotes environmental responsibility. For those looking for a reliable and efficient way to maintain their lawn, this mower is a fantastic choice. To learn more and purchase your own, click here to visit the product page.
