•Quick and easy start every time, no hassle.
•Remarkably quiet operation allows for mowing any time without disturbing neighbors.
•Handles thick St. Augustine grass and slopes with ease.
•Battery life can exceed an hour, covering a 1/4 acre effectively with power to spare.

•The variable speed feature is great for customizing the cutting experience.
•Mulches beautifully, ideal for maintaining a neat lawn appearance.
•Great choice for seniors due to its lightweight and easy handling.

Cons

•Battery life isn't sufficient for averagized lawns if you plan to mow both front and back in one go; may require a second charge.
•The 2 AH battery only lasts about 30 minutes, which might be too short for larger areas.

Bottom Line

The Greenworks PRO 21-Inch Cordless Lawn Mower is a solid choice for those looking for a quieter, more environmentally-friendly alternative to gas mowers. It's especially adept at handling various terrains and tough grass types with ease. However, for larger lawns, you might need to consider an additional battery for continuous mowing without interruption. Its ease of use makes it particularly appealing for seniors or those new to cordless mowers. If battery life is a primary concern, you might want to explore additional battery options to ensure uninterrupted cutting performance.
