Check drive type and weight

  1. Match drive to slope

    If your lawn has slopes, self-propelled models reduce physical effort. The Greenworks 60V 21-Inch Self-Propelled Mower uses a drive system to move forward. This helps you maintain a steady pace on inclines. Push models require you to provide all the force. Choose self-propelled if you struggle with pushing. Select push models for flat, small yards where light weight matters more than ease of movement.

  2. Consider weight for storage

    Weight affects how easily you lift and store the mower. The Greenworks 24V 13-Inch Push Lawn Mower weighs only 24 pounds. This makes it simple to carry up stairs or into a small shed. Heavier models like the 80V 25-Inch Self-Propelled Mower weigh 78 pounds. These are harder to move. Pick a lighter unit if you have limited storage space or physical limitations.

  3. Choose cutting width wisely

    Cutting width determines how many passes you need. A 25-inch deck covers more ground per pass than a 16-inch deck. The Greenworks 80V 25-Inch Self-Propelled Mower offers wide coverage. This reduces total mowing time for large areas. Narrow decks like the 13-inch model require more passes. Use a wider deck for open, obstacle-free lawns. Use narrower decks for tight spaces between garden beds.

  4. Select voltage for power

    Voltage indicates the power level of the motor system. Higher voltage generally means more torque for thick grass. The 80V models provide robust power for challenging conditions. Lower voltage options like 24V and 40V are sufficient for standard lawn care. Match the voltage to your grass type and yard size. You do not need 80V power for a small, flat yard. Save weight by choosing lower voltage if power demands are modest.

  5. Check motor type

    Brushless motors offer longer life and better efficiency. The Greenworks 40V 25-Inch Self-Propelled Mower features a brushless motor. This type requires less maintenance over time. It also runs cooler and uses battery energy more effectively. Standard brushed motors are simpler but may wear out faster. Check the product attributes for motor type. Choose brushless if you plan to use the mower frequently for years.

Frequently asked questions

Which Greenworks mower with a 4.0 Ah battery is the lightest?

The Greenworks 24V 13-Inch Push Lawn Mower is the lightest option at 24 pounds. Its compact design makes it ideal for tight spaces and small yards. You get a 13-inch cutting width, which is narrower than most other models. This low weight ensures easy maneuverability around obstacles.

Do all these mowers use the same 4.0 Ah battery?

Yes, every model listed is compatible with 4.0 Ah batteries. However, some models like the Greenworks 60V 21-Inch Self-Propelled Mower and the 48V 20-Inch Cordless Push Mower are designed to use two 4.0 Ah batteries simultaneously. This dual-battery setup provides extended runtime for larger yards or tougher cutting conditions.

What is the widest cutting deck available in this list?

The widest cutting deck is 25 inches, found on both the Greenworks 80V 25-Inch Self-Propelled Mower and the Greenworks 40V 25-Inch Self-Propelled Mower. These models offer the broadest coverage per pass. They are best suited for large lawns where covering ground quickly is a priority. The wider deck reduces the number of passes needed.

Which models are self-propelled rather than push mowers?

The self-propelled models in this list are the Greenworks 60V 21-Inch Self-Propelled Mower, the Greenworks 80V 25-Inch Self-Propelled Mower, the Greenworks 80V 21-Inch Self-Propelled Mower, and the Greenworks 40V 25-Inch Self-Propelled Mower. These models move forward on their own, reducing physical effort. They are ideal for slopes or larger properties where walking behind a push mower is tiring.

Are there brushless motor options in this collection?

Yes, the Greenworks 40V 25-Inch Self-Propelled Mower and the Greenworks 80V 21-Inch Self-Propelled Mower feature brushless motors. Brushless motors generally offer longer life and more efficient power usage. This technology helps extend runtime per battery charge. These models are suitable for users who want durable performance and consistent power output over time.

Is there a Greenworks mower suitable for dethatching?

The Greenworks 48V 15-Inch Cordless Dethatcher and Scarifier is designed for lawn aeration and dethatching tasks. It uses a 4.0 Ah battery and weighs only 26 pounds. This specialized tool is not a mower but a dedicated attachment for grooming lawns. It fits users who already have the 24V battery platform and want to expand their toolkit.
