Choosing between a 50 ah vs 60 ah lawn mower often comes down to voltage and runtime needs. You are comparing the Greenworks 40V model with a 5.0 Ah battery against the EGO 56V model with 6.0 Ah batteries. Both are self-propelled cordless mowers designed for residential lawns. The main difference lies in their power systems and deck sizes. One offers a steel deck with variable speed, while the other provides a composite deck with touch drive technology.

Which one should you choose?
Choose Greenworks 40V 21-Inch Self-Propelled Mower if
- You prefer a lighter mower that weighs 73.9 pounds for easier handling.
- You need a 4-in-1 system that includes side discharge and leaf pickup options.
- You already own a collection of 40V Greenworks tools for battery compatibility.
Choose EGO 22-Inch Self-Propelled Super Composite if
- You want a wider 22-inch cutting width to cover more ground per pass.
- You need up to 90 minutes of runtime with two included 6.0 Ah batteries.
- You prefer a rust-resistant Super Composite deck backed by a 10-year warranty.
Verdict: Choose the Greenworks model if you prioritize versatility with four mowing modes and a lighter weight. Select the EGO mower if you need greater cutting width, longer runtime, and a corrosion-resistant deck. Your decision should depend on whether you value multi-functionality or raw power and deck durability.
5.0 Ah vs 6.0 Ah Mower Specs
Voltage and Power
The Greenworks 40V model operates on a 40V battery system, while the EGO Power+ mower uses a 56V battery platform. Higher voltage often translates to more torque and sustained power under load. The EGO specifies up to 10.6 ft-lbs of cutting torque and blade speeds reaching 3,200 RPM. This suggests the 56V system may handle thick or wet grass with less strain on the motor. The Greenworks brushless motor is noted for superior torque relative to its class, but the voltage difference remains a key technical distinction. You should consider if your lawn requires the higher voltage headroom provided by the EGO system.
Battery Runtime
Battery capacity directly influences how long you can mow before recharging. The EGO mower includes two 56V 6.0Ah ARC Lithium batteries, providing up to 90 minutes of runtime on a single charge. The Greenworks mower comes with a single 5.0Ah battery. While the Greenworks battery is compatible with over 75 other tools in the 40V ecosystem, the EGO setup offers a higher total amp-hour capacity in the included package. If you have a larger lawn, the 90-minute runtime of the EGO with its dual batteries provides a clear advantage in continuous mowing time without interruption.
Cutting Width
The deck width determines how much grass you cut in a single pass. The Greenworks mower features a 21-inch steel deck, while the EGO mower has a 22-inch Super Composite deck. The one-inch difference means the EGO covers slightly more ground per pass, which can reduce total mowing time for large areas. The Greenworks 21-inch width is a standard size that fits well in most residential yards. Both widths are practical for typical lawns, but the wider deck on the EGO offers a marginal efficiency gain for extensive grassy areas.
Drive System
Both mowers are self-propelled, reducing the physical effort required to push them. The Greenworks model features rear-wheel drive with variable speed control, allowing you to adjust the pace to match your walking speed. The EGO mower uses Touch Drive technology, which engages self-propulsion with a palm touch and allows speed adjustment via a dial. Both systems offer hands-free operation and traction on various terrains. The EGO’s touch activation may offer quicker engagement, while the Greenworks variable speed provides manual control. Neither has a clear technological superiority, making this a practical tie.
Mowing Functions
Versatility in grass handling is important for lawn health and cleanup. The Greenworks mower offers a 4-in-1 system that includes mulching, bagging, side discharge, and turbo leaf pickup. This allows you to manage leaves and grass clippings in multiple ways. The EGO mower focuses on bagging and mulching with its Select Cut Multi-Blade system, which includes interchangeable lower blades for high-performance and high-lift bagging. While the EGO offers specialized blade options, the Greenworks provides more varied discharge modes, including side discharge and leaf pickup, for different yard conditions.
Deck Material and Weight
The deck material affects durability and overall mower weight. The Greenworks uses a 21-inch steel deck, which is known for strength but adds significant weight. The EGO mower features a 22-inch Super Composite deck, which is lightweight and resistant to dents, rust, and corrosion. The Greenworks weighs 73.9 pounds, while the EGO weighs 120 pounds, largely due to the dual batteries and composite construction. Steel offers traditional durability, while composite provides rust resistance. The choice depends on whether you prioritize lightweight maneuverability or traditional steel toughness.
5.0 Ah vs 6.0 Ah Mower Picks
Users needing maximum runtime and torque
The EGO 56V system delivers up to 10.6 ft-lbs of torque and 3,200 RPM blade speeds. It includes two 6.0Ah batteries for up to 90 minutes of runtime. This higher voltage and dual-battery setup supports larger lawns or thicker grass without losing power under load.
Mowers wanting lighter weight and night use
The Greenworks 40V model weighs 73.9 pounds, significantly lighter than the EGO at 120 pounds. It features built-in LED headlights for early morning or late evening mowing. The 21-inch steel deck and brushless motor offer efficient cutting with quieter operation than gas mowers.
Those prioritizing long deck warranty
The EGO mower includes a 10-year limited warranty on its Super Composite deck. This deck resists dents, rust, and corrosion. The 22-inch cutting width and Touch Drive self-propel system add convenience. This warranty provides long-term protection for the primary cutting component.
Users wanting versatile discharge options
The Greenworks mower offers a 4-in-1 mowing system. You can mulch, bag, side discharge, or perform turbo leaf pickup. This versatility allows you to customize lawn care for different needs. The 3-year warranty covers the tool and battery, supporting long-term ownership.

Frequently asked questions
Does a 6.0 Ah battery last longer than a 5.0 Ah battery?
Yes, a 6.0 Ah battery typically provides more runtime than a 5.0 Ah option. The EGO model with 6.0 Ah batteries offers up to 90 minutes of cutting time. This extended duration suits medium-sized lawns where you need to finish the job in one go without swapping batteries.
Is the EGO mower more powerful than the Greenworks model?
The EGO mower operates on a 56V system, while the Greenworks uses 40V. Higher voltage often results in more torque and sustained power. The EGO delivers 10.6 ft-lbs of torque and 3,200 RPM blade speeds, which helps maintain cutting efficiency under heavy load compared to the lower voltage alternative.
Which mower is better for large lawns?
The EGO 22-Inch model is better for larger areas due to its extended runtime. It includes two 6.0 Ah batteries for up to 90 minutes of operation. The Greenworks 21-Inch model uses a 5.0 Ah battery, which may require a spare or recharging sooner for extensive mowing tasks.
Are both mowers self-propelled?
Yes, both the Greenworks and EGO models feature self-propelled drive systems. This means the mower moves forward on its own, reducing the physical effort required to push it. You only need to guide the machine, making it easier to handle on slopes or uneven terrain.
What is the difference in deck width between the two?
The EGO mower has a 22-inch cutting width, while the Greenworks model features a 21-inch deck. The wider cut on the EGO allows you to cover more ground with each pass. This difference can slightly reduce the total time needed to mow a large yard.
Does the Greenworks mower have a steel deck?
Yes, the Greenworks 40V model is noted for its steel deck durability. Steel decks generally offer better longevity and impact resistance compared to composite materials. This makes the Greenworks a solid choice for users who prioritize a robust build and versatile mowing modes over maximum battery runtime.
How much does the EGO mower weigh?
The EGO 22-Inch Self-Propelled Super Composite weighs 120 pounds. This substantial weight comes from the durable composite deck and the inclusion of two heavy batteries. The Greenworks model weighs 73.9 pounds, making it significantly lighter and potentially easier to maneuver or lift for storage.
