In the sprawling world of lawn care, I’ve had the pleasure of testing a myriad of machines. Lawnmowers, in particular, have always held a fascination for me, evolving rapidly in response to the growing demand for eco-friendly, efficient products. 

Today, I’ll walk you through my experience with the Greenworks 48V 20″ Brushless Cordless Push Lawn Mower, a model that has gained significant traction in the market.

What I Like

What I Don't Like

Features of the Greenworks 48V 20" Brushless Cordless Push Mower

Unboxing and Assembly

Upon receiving the Greenworks 48V 20″ Brushless Cordless Push Lawn Mower, the first thing that stood out was the packaging. 

Like the Greenworks 25302, it’s clear that Greenworks has made a concerted effort to ensure that every component is securely packed, which protects the parts from any potential damage during shipping.

Assembly is a breeze. The manual provided is straightforward with clear instructions and illustrations. 

Most of the mower is pre-assembled, so it’s mostly about attaching the handles and ensuring everything is securely in place. It might take about 15 minutes tops; for machine newbies perhaps 30 minutes. 

The Brushless Advantage

Brushless motor technology is not just a buzzword. It offers tangible benefits. Traditional brushed motors suffer from friction and voltage drops, leading to a loss in energy efficiency. 

With the Greenworks brushless motor, there’s a distinct improvement in power delivery. During extensive tests, the mower ran longer and with more torque, ensuring a clean, consistent cut.

Battery Life and Power

This mower operates on a 48V system powered by two 4.0Ah batteries. For an average-sized lawn (about a quarter of an acre), a single charge sufficed. 

The transition from gas-powered engines to battery-driven ones has not been easy for many, but with mowers like these that deliver reliable performance, the future looks promising.

Cutting Efficiency

A lawn mower’s prime function, the actual cutting must be impeccable. The 20-inch wide cutting deck of this Greenworks model allows for fewer passes, saving time and energy. 

I was also impressed with the ease of adjusting the cutting height, giving me full control over the final lawn appearance.

Maneuverability

Weighing in at 67.9 pounds, the Greenworks 48V 20″ mower is neither the lightest nor the heaviest in its class. 

However, its weight is well-distributed, making it easy to push around obstacles. It’s not self-propelled, which might be a downside for some, but its straightforward push mechanism quite reliable. On sloping terrains, a bit of muscle might be required, but it’s manageable.

Eco-friendliness

With the growing concerns about environmental degradation, the Greenworks 48V mower shines as an eco-friendly option. Its battery-operated system emits no harmful pollutants, ensuring that your lawn care routine doesn’t harm Mother Nature. 

In addition, electric mowers, like the Craftsman CMEMW213, in general, have a smaller carbon footprint [1] compared to their gas-powered counterparts, and Greenworks has done an exceptional job in ensuring their product leads the way in this respect.

Maintenance and Durability

Brushless motors inherently require less maintenance. Without brushes to replace and no oil changes to worry about, upkeep is minimal. 

The alloy steel build promises durability, but only time will truly tell. Still, based on my experience, Greenworks products have a commendable lifespan. (But Black+Decker’s MM2000 mower is a good contender, too!)

Performance Summary

Electric mowers, especially ones from Greenworks, stand out with significantly reduced carbon emissions. This not only ensures a greener planet but also a healthier lawn.

Review Conclusion: Greenworks 48V 20-inch Cordless Push Lawn Mower

While the electric mowers come with a bounty of advantages like quieter operation, no emissions, and lesser maintenance, they aren’t without their challenges. The dependency on battery life can sometimes be a limitation, especially for uneven terrains.
