Greenworks 40V 17" Cordless Lawn Mower – Brushless Motor, 4.0Ah Battery & Charger (75+ Compatible Tools), 2-in-1 Mulch/Bag

What It Is

This is a complete 40V cordless lawn mower system from Greenworks, including a 17-inch deck, brushless motor, 4.0Ah battery, and charger. It’s designed for small to medium lawns (up to 1/4 acre) and is part of Greenworks’ 40V family, meaning the battery works with 75+ other tools like trimmers and blowers.

Fitment & Compatibility

• Deck size: 17 inches – best for tight spaces, small yards, or trimming around gardens.
• Model fit: This is the mower itself, not a standalone battery. Confirm your Greenworks 40V tools use the same G-Max battery platform (most do, but check your tool’s voltage and connector shape).
• OEM vs aftermarket: OEM Greenworks battery and charger included. Aftermarket 40V batteries may work but can cause performance or charging issues.
• Before buying: Measure your lawn area and gate width (17” deck fits through most standard gates). Verify you don’t already own a 40V Greenworks battery you could use with a bare tool version (sold separately).

Key Things to Know

• Brushless motor: More efficient and quieter than brushed motors; longer runtime and less maintenance.
• Battery runtime: 4.0Ah battery gives roughly 30-40 minutes on a full charge (mulching uses more power). For lawns over 1/4 acre, consider a second battery.
• Installation: Minimal assembly – attach handle, lower handle, and bag. No tools required for most steps.
• Common gotcha: The 2-in-1 design means no side discharge; you must use the included mulching plug or bag. If you need side discharge, look for a 3-in-1 model.

Should You Buy It

Buy this if you have a small, flat lawn and want a lightweight, low-maintenance mower that shares batteries with other Greenworks 40V tools. Skip it if your lawn is over 1/4 acre, uneven, or you need side-discharge capability – a 21-inch model or gas mower would be a better fit.
