80V 21 in Brushless Cordless Push Lawn Mower - Quiet, Gas-Like Power

Our review of the Greenworks 80V 21 in brushless push mower finds it best for homeowners who want gas-like cutting performance without the maintenance and noise of a combustion engine. The single biggest reason to consider this mower is its brushless TRUBRUSHLESS motor paired with two 80V 2.0Ah batteries, which delivers strong torque and a surprisingly quiet run while handling thick grass and hills more easily than typical cordless models. It is lightweight and user-friendly, making regular mowing for yards up to about 1 acre straightforward for most users.

Key Features

• 80V Platform: Provides up to 60 minutes of run-time with two fully charged 2.0Ah batteries under ideal conditions, letting many homeowners finish a typical lawn on a single charge.
• Brushless Motor: The TRUBRUSHLESS design delivers more torque and longer motor life while running quieter than a comparable gas mower.
• 3-in-1 Cutting: Mulch, rear bag, or side discharge options make it easy to manage different grass conditions and cleanup preferences.
• Single-Lever Height Adjustment: A five-position adjustment lets users change cutting height quickly for different seasons and turf types.
• Durable Build: A steel 21 in deck with large 10 in rear wheels adds stability and durability on uneven yards and light slopes.
• Maintenance Free: No gas, no oil, and push-button start reduce upkeep and eliminate emissions associated with small engines.

Who It's For

This mower suits homeowners with medium-size yards up to around 1 acre who want the look and cut quality of a gas mower without routine engine maintenance or fumes. It is also a good pick for users who value quiet operation and easy handling - the lightweight design and large rear wheels help maneuver around landscaping.

It may not be ideal for those who need continuous, full-day commercial use without swapping batteries, or buyers who expect consistently long runtime from the included 2.0Ah batteries; some users report varied battery life, so consider adding higher-capacity batteries for extended runs.

Pros & Cons

Pros

• Strong, gas-like cutting performance from the brushless motor with quiet operation.
• Flexible 3-in-1 cutting options and easy single-lever height adjustment for different turf needs.
• Lightweight and maneuverable with large rear wheels that make hills and obstacles easier to manage.
• Maintenance free operation eliminates oil changes and fuel storage.

Cons

• Runtime varies by grass condition and technique; some users report only 15-20 minutes on the included batteries, so additional batteries may be necessary for larger jobs.
• Included 2.0Ah batteries are convenient but may be undersized for continuous heavy-duty mowing without swaps.
