Key Features of Greenworks 40V 16″ Cordless

Effortless Power for Small to Medium Yards

The Greenworks 40V 16″ Cordless delivers powerful performance comparable to gas models, but without the emissions or noise. Its 40-volt battery provides sufficient torque to cut through typical grass and light overgrowth, making it ideal for yards up to half an acre. In my tests, it handled regular grass with ease and even tackled slightly overgrown patches without stalling.

Ultra-Lightweight and Easy to Maneuver

Weighing roughly 35% less than traditional gas mowers, this model is a breeze to push and steer. The ergonomic handles and lightweight design mean less fatigue, especially during longer mowing sessions. If you have mobility issues or simply prefer a mower you can carry easily, this is a significant advantage.

Smart Cut Adjustment System

The single-lever 5-position height adjustment (from 1.25″ to 3.375″) allows quick and precise control over grass height, accommodating different grass types and personal preferences. Whether you want a close cut or a slightly taller lawn, switching heights is straightforward, making your mowing tailored and efficient.

2-in-1 Mulching and Rear-Bagging System

This feature maximizes grass clipping management. You can mulch for a healthier lawn or use the rear bag to collect clippings, keeping your yard tidy. The switch between modes is seamless, and the system is designed to prevent clogging, even with damp grass.

No Maintenance, Maximum Savings

Unlike gas mowers, the Greenworks 40V 16″ Cordless requires no oil changes, spark plugs, or engine tune-ups. It’s whisper-quiet (<75dB), making it suitable for noise-sensitive neighborhoods. Plus, the absence of gas and oil means you save over $200 annually on fuel and maintenance costs.

Complete Ecosystem and Compatibility

The package includes a 4.0Ah battery and fast charger, plus a grass bag. The mower is compatible with over 75 Greenworks tools—such as trimmers, blowers, and chainsaws—so you can expand your cordless toolkit over time. This ecosystem approach offers excellent value and convenience.

How Does Greenworks 40V 16″ Cordless Perform?

Scenario 2: Overgrown or Slightly Wet Grass

When faced with slightly overgrown grass, the mower performed admirably. Its powerful motor tackled thicker patches without stalling. The mulching system shredded clippings finely, and the rear bag filled up quickly, indicating good collection efficiency. Wet grass was manageable, thanks to the blade design, though a bit more care is advisable to prevent clogging.

Scenario 3: Long-term Use and Ease of Storage

Because of its ultra-lightweight build, I found storing and transporting the mower effortless. Its compact size makes it easy to store in small spaces. Additionally, the quiet operation means I can mow early mornings or late evenings without disturbing neighbors.
