Specs: Power, Width, and Drive
Cutting Width
Edge: Greenworks 60V 21-Inch Self-Propelled Mower
The Greenworks 60V 21-Inch Self-Propelled Mower features a 21-inch cutting deck, while the Greenworks 40V 14-Inch Cordless Push Mower has a 14-inch deck. A wider deck covers more ground per pass, reducing the number of times you need to mow the same area. This makes the 60V model significantly faster for larger lawns. The 14-inch width is better suited for small, tight spaces or narrow yards where maneuverability matters more than speed. You should choose the 21-inch model if you want to finish your lawn quickly. The 14-inch model is ideal for smaller plots where a wide deck might be cumbersome. This difference in width directly impacts your mowing time and efficiency.
Voltage and Power
Edge: Greenworks 60V 21-Inch Self-Propelled Mower
The Greenworks 60V 21-Inch Self-Propelled Mower operates on a 60V platform, whereas the Greenworks 40V 14-Inch Cordless Push Mower uses a 40V system. Higher voltage generally translates to more power and torque, allowing the mower to handle thicker grass and steeper slopes with ease. The 60V model also includes a brushless motor, which is more efficient and durable than standard motors. The 40V model is sufficient for light to moderate grass conditions but may struggle in dense or wet turf. If you have a challenging lawn, the 60V system provides the necessary strength to maintain a consistent cut. The 40V system is lighter and less powerful, making it suitable for basic maintenance tasks.
Drive Type
Edge: Greenworks 60V 21-Inch Self-Propelled Mower
The Greenworks 60V 21-Inch Self-Propelled Mower has a self-propelled drive, meaning the wheels turn automatically to push the mower forward. The Greenworks 40V 14-Inch Cordless Push Mower requires you to push it manually. Self-propelled models reduce physical effort, especially on hills or in thick grass. You simply guide the mower rather than forcing it forward. This feature is crucial for larger yards or uneven terrain. The push model demands more physical exertion from you, which can be tiring over time. If you have mobility issues or a large lawn, the self-propelled drive is a significant advantage. The push model is better for flat, small areas where manual effort is manageable.
Mowing Functions
Edge: Greenworks 60V 21-Inch Self-Propelled Mower
The Greenworks 60V 21-Inch Self-Propelled Mower offers a 4-in-1 system, including mulching, bagging, side discharge, and turbo leaf pickup. The Greenworks 40V 14-Inch Cordless Push Mower provides a 2-in-1 function with mulching and rear bagging only. The additional side discharge and leaf pickup options on the 60V model give you more flexibility in how you handle clippings and debris. This is useful if you want to leave clippings on the lawn for nutrient recycling or clear leaves efficiently. The 40V model is limited to rear bagging and mulching, which may not suit all lawn care preferences. If you need versatility in debris management, the 60V model is the better choice. The 40V model is adequate for basic grass management.
Battery Capacity
Edge: Greenworks 60V 21-Inch Self-Propelled Mower
The Greenworks 60V 21-Inch Self-Propelled Mower comes with two 4.0 Ah batteries, while the Greenworks 40V 14-Inch Cordless Push Mower includes one 4.0 Ah battery. Having two batteries allows for extended runtime and the ability to swap out depleted batteries quickly without waiting for a recharge. The 60V model is rated for up to 3/4 acre per charge with the dual batteries. The 40V model offers up to 45 minutes of runtime, which is suitable for smaller areas. If you have a large lawn, the dual battery system ensures you can complete the job without interruption. The single battery on the 40V model may require recharging mid-job for larger tasks. The 60V setup provides greater endurance and convenience for extensive mowing.
