Finding the best greenworks 21-Inch lawn mowers requires looking closely at the technical details. We compared 11 models using only the specifications published on their listings. The top pick is the Greenworks 40V 21-Inch Self-Propelled Mower. It leads because its 5.0 Ah battery provides strong torque for sloped lawns. This guide helps you decide which drive type and voltage match your yard size. You will see how weight and cutting width affect maneuverability. Read on to find the right mower for your specific needs.
Match voltage and drive to your lawn
Your choice depends on yard size and terrain. Choose self-propelled models for slopes or large areas to reduce effort. Select push models for small, flat lawns.

Key Specs to Compare
Check Drive Type
You must decide between self-propelled and push models based on your terrain. Self-propelled drives reduce physical effort, which is essential for slopes or large yards. The Greenworks 40V 21-Inch Self-Propelled Mower offers variable speed control for uneven ground. Conversely, push models like the Greenworks 80V 21-Inch Cordless Push Mower are lighter and easier to store. Choose self-propelled if you want to minimize exertion. Select push models for small, flat lawns where manual pushing is manageable.
Evaluate Voltage Options
Voltage indicates the power potential of the motor system. Higher voltage numbers like 80V or 82V generally provide more torque and runtime. The Greenworks 82V 21-Inch Self-Propelled Mower delivers robust power for demanding tasks. Lower voltage options, such as the 40V models, are sufficient for standard residential mowing. The Greenworks 40V 21-Inch Self-Propelled Mower balances power with efficiency. Match the voltage to your grass height and density. Higher voltage suits thick or wet grass better than lower voltage systems.
Compare Battery Capacity
Battery capacity, measured in Amp-hours (Ah), determines how long the mower runs before needing a recharge. Larger capacities like 8.0 Ah extend runtime significantly. The Greenworks 82V 21-Inch Self-Propelled Mower features an 8.0 Ah battery for extended operation. Smaller capacities, such as 2.0 Ah, may require swapping batteries for larger yards. The Greenworks 80V 21-Inch Push Mower and Blower Kit includes 2.0 Ah batteries. Check the Ah rating to ensure the mower covers your entire lawn on a single charge.
Consider Motor Type
Brushless motors offer higher efficiency and longer lifespan compared to brushed motors. They maintain consistent power output as the battery drains. Many Greenworks models, including the 60V and 80V variants, feature brushless technology. This ensures reliable performance throughout the cutting session. The Greenworks 60V 21-Inch Self-Propelled Mower uses a brushless motor for balanced power. Brushless motors also require less maintenance.
