Greenworks 40V 16" (Push) Cordless Lawn Mower, 4.0Ah Battery (1/3 Acre, Push Button Start, Compatible with 75+ Tools)

What It Is

This is a complete 40V cordless lawn mower system from Greenworks, not a standalone battery. It includes a 16-inch steel deck, push-button start, and a 4.0Ah battery/charger—designed for trimming up to 1/3 acre of grass on flat, small-to-medium lawns.

Fitment & Compatibility

• Deck size: 16-inch cut—suits yards under 1/3 acre; tight for larger lawns.
• Battery/charger: Uses Greenworks 40V G-MAX Lithium batteries (4.0Ah included). This battery is not compatible with older Greenworks 24V or 60V tools. It works with 75+ Greenworks 40V tools (trimmers, blowers, chainsaws) but only if they are G-MAX labeled.
• OEM vs aftermarket: This is OEM. Aftermarket 40V batteries may fit but often lack the same charge protection or warranty. Stick with Greenworks-branded 40V batteries for reliable performance.
• What to check: Measure your lawn size (under 1/3 acre recommended). Verify your existing Greenworks tools are 40V G-MAX—not 24V or 60V. The mower itself is a push model, not self-propelled.

Key Things to Know

• Quality: Solid build for the price, but the plastic deck may crack under heavy use on uneven terrain. Battery life averages 30-40 minutes on a full charge—enough for a standard 1/4-acre lot in one pass.
• Installation: No assembly required beyond attaching the handle (takes 5 minutes). Push-button start is reliable, but the battery must be fully seated.
• Common gotchas: The single 4.0Ah battery may not finish a full 1/3-acre mow if grass is thick or wet. Consider buying a second 40V 4.0Ah battery for larger jobs. The mower is not self-propelled—pushing on slopes is tough. Also, the battery contacts can corrode if stored damp; always dry the battery and mower before storage.
• Warranty: 4-year limited on the mower, 2-year on the battery. Register online to activate.

Should You Buy It

Buy this if you have a flat, small lawn (under 1/3 acre) and already own Greenworks 40V tools—the battery swaps across your gear. It’s a reliable, low-maintenance entry-level cordless mower, but skip it if you need self-propulsion or have a larger, hilly yard.
