Greenworks 40V 21in Self-Propelled Mower Kit - Cordless Yard Power

Our review of the Greenworks 40V 21in Self-Propelled Lawn Mower kit finds it best for homeowners with small to medium yards who want a quieter, lower-maintenance alternative to gas equipment. The biggest reason to consider this kit is the trio of tools that share the 40V platform: a 21in self-propelled mower, a 13in string trimmer that converts to an edger, and a powerful axial leaf blower, all supported by a 5.0Ah and a 2.0Ah battery. For routine lawn care, the package simplifies storage and delivers good cut quality with notably low noise.

Key Features

• Enhanced traction: 8in front wheels and rear-wheel drive give confident handling on uneven or slightly hilly yards, making turns and climbs easier than typical rear-drive mowers.
• Robust mower performance: The 21in steel deck combined with a brushless motor provides strong torque for clean cuts and a longer motor life with quieter operation than combustion engines.
• Versatile trimmer/edger: The 13in string trimmer converts to an edger with a 90 pivoting head for precise borders along driveways and flowerbeds.
• Powerful blower: The axial leaf blower delivers 500 CFM and up to 120 MPH with variable speed and a turbo boost for fast cleanup of leaves and debris.
• Good runtime and platform: The included 5.0Ah battery can deliver up to about 45 minutes runtime for moderate use, and the 40V platform works with over 75 Greenworks outdoor tools.
• Warranty peace of mind: A 3-year tool warranty and 2-year battery warranty provide reasonable coverage for this class of cordless kit.

Who It's For

This kit suits suburban homeowners, seniors, or anyone who mows lawns up to about 1,000 sq ft regularly and prefers lightweight, low-noise equipment. The self-propelled feature and ergonomic design reduce fatigue during multiple passes, and the included blower and trimmer expand its usefulness for seasonal cleanup and edging.

It is not aimed at large properties or commercial use where extended continuous runtime and heavy-duty capacity are required; users with very large lots should look for higher-capacity battery systems or professional-grade equipment.

Frequently Asked Questions

How long will the battery run the mower?
The included 5.0Ah battery can deliver around 45 minutes of runtime under moderate conditions, though actual time varies with grass height and throttle use.

Can the trimmer head become an edger easily?
Yes, the trimmer converts to an edger using its 90 pivoting head for precise edging along sidewalks and beds.

Is the blower powerful enough for wet leaves?
The blower produces 500 CFM and 120 MPH with a turbo mode, which handles most dry and light-moderate wet leaf cleanup; very heavy wet debris may need more passes.
