Greenworks 60V 21 in Self-Propelled Cordless Lawn Mower - Quiet Power

Our review of the Greenworks 60V 21 in Self-Propelled Cordless Lawn Mower finds it best suited for homeowners who want gas-like cutting performance without the noise and fuss of fuel. The single biggest reason to consider this mower is the combination of a brushless motor and dual 4.0Ah batteries that deliver long runtime and consistent power, allowing one session to cover up to about 3/4 acre while running substantially quieter than a gas machine. Assembly is straightforward and the included rapid dual-port charger gets both batteries back to work quickly.

Key Features

• Brushless Motor: Delivers gas-like cutting torque and efficiency while reducing maintenance compared with brushed designs.
• Dual Battery System: Two 4.0Ah 60V batteries with auto switchover provide about 60+ minutes of continuous runtime for larger yards.
• Self-Propelled Rear-Wheel Drive: Rear-wheel traction and on-the-go pace adjustment make it easier to handle slopes and thick grass without constant pushing.
• LED Headlight: Ultra-bright LEDs allow mowing at dawn or dusk and improve visibility in shaded areas.
• 4-IN-1 Versatility: Mulch, bag, side discharge, and turbo leaf pickup options adapt to seasonal cleanup and differing grass conditions.
• Complete Ecosystem Value: Ships with batteries, a rapid dual-port charger, and a grass bag, and works with over 75 tools in the same 60V platform.

Who It's For

This mower is ideal for homeowners with medium-size yards up to roughly 3/4 acre who want a low-maintenance, emissions-free alternative to gas. It suits people who value quiet operation for early morning or noise-sensitive neighborhoods and who appreciate a kit that includes batteries and a fast charger so it is ready to use out of the box.

Those with very large properties well over an acre, or users who require extremely long continuous runtime without battery swaps, should consider commercial gas or larger battery rigs. Also, if you need a rear-bag-only setup or a zero-turn for complex landscaping, a different model may be a better match.

Pros & Cons

Pros

• Strong cut performance from the brushless motor while running much quieter than gas.
• Long practical runtime from the dual 4.0Ah batteries with auto switchover for continuous mowing.
• Easy to assemble and maneuver thanks to the self-propelled rear-wheel drive and relatively light weight.
• Included charger, batteries, and 4-IN-1 discharge options add immediate value and versatility.

Cons

• Batteries provide good but finite runtime, so very large lots may require extra battery purchases for extended work sessions.
• The weight distribution may take a short adjustment period when mowing on steep slopes for some users.

What discharge and cutting options are available?
The mower supports 4-IN-1 operation: mulch, rear bag, side discharge, and a turbo leaf pickup mode for seasonal cleanup.
