When comparing a 40 ah vs 80 ah lawn mower, you are looking at two distinct approaches to yard care. Both models are push mowers powered by cordless batteries, offering easy maneuverability and zero emissions. The primary difference lies in the battery capacity and cutting width. One features a larger 16-inch deck with a 4.0 Ah battery, while the other uses a 14-inch deck paired with an 8.0 Ah battery. These specs dictate how much area you can cover and how long the tool runs on a single charge.
Key differences
| Aspect | Greenworks 40V 16-Inch Push Lawn Mower | Litheli 14-Inch Brushless Cordless Mower |
|---|---|---|
| Cutting Width | 16 in | 14 in |
| Battery Capacity | 4.0 Ah | 8.0 Ah |
| Motor Type | not listed | Brushless |
| Mowing Function | Mulch and rear bag | Bag |
| Weight | 37.5 pounds | 33.1 pounds |
Which one should you choose?
Choose Greenworks 40V 16-Inch Push Lawn Mower if
- You need a wider cutting path to cover more ground per pass.
- You prefer the option to mulch clippings back into the lawn.
- You already own other 40V Greenworks tools for a shared battery system.
Choose Litheli 14-Inch Brushless Cordless Mower if
- You want extended runtime for larger or denser grass areas.
- You value a lighter, more compact mower for easy storage.
- You prefer a maintenance-free brushless motor with quiet operation.
Verdict: Choose the Greenworks if you prioritize a wider cutting deck and mulching versatility. Pick the Litheli if you need longer runtime and a lighter, brushless motor design. Your decision depends on whether you value cut width or battery endurance more.
Battery Capacity and Runtime Comparison
Battery Capacity
Product A, the Greenworks 40V 16-Inch Push Lawn Mower, uses a 4.0 Ah battery. Product B, the Litheli 14-Inch Brushless Cordless Mower, features a larger 8.0 Ah battery. The higher capacity in the Litheli model suggests a greater potential for energy storage. This difference is significant for users with larger yards or those who prefer longer continuous operation without swapping batteries. The Greenworks unit relies on its smaller 4.0 Ah cell, which may require more frequent recharging during extensive mowing sessions. You should consider how often you mow and the size of your lawn when deciding which capacity suits your needs best.
Cutting Width
The Greenworks mower offers a 16-inch cutting width, while the Litheli model provides a 14-inch cutting width. The wider deck on the Greenworks allows you to cover more ground with each pass. This can reduce the total time required to mow larger areas. The Litheli’s narrower 14-inch deck is designed for maneuverability, making it easier to navigate around tight spaces, flower beds, and obstacles. If your lawn is open and expansive, the Greenworks width might be more efficient. For yards with many barriers, the Litheli’s compact cut may be preferable. Both widths are standard for push mowers in this class.
Motor Type
Product B, the Litheli mower, specifies a brushless motor type. Product A, the Greenworks mower, does not explicitly list its motor type in the provided data. Brushless motors generally offer improved efficiency, longer lifespan, and reduced maintenance compared to brushed motors. The Litheli’s brushless design may provide more consistent power delivery and less wear over time. Since the Greenworks specifications do not confirm the motor type, you cannot directly compare the internal mechanics. However, the absence of this detail for Greenworks means you might need to check other sources or assume a standard brushed configuration. The Litheli’s explicit brushless claim is a technical advantage for long-term reliability.
Mowing Function
Product A, the Greenworks mower, features a 2-in-1 system that supports both mulching and rear bagging. Product B, the Litheli mower, is listed with a bagging function only. The Greenworks versatility allows you to choose between returning nutrients to the lawn via mulching or collecting clippings in a bag. The Litheli model appears to be dedicated to bagging, which keeps the lawn clean but removes grass clippings entirely. If you prefer to leave clippings on the lawn for natural fertilization, the Greenworks offers that option. If you strictly want to collect all debris, the Litheli fulfills that single purpose effectively. Your preference for lawn health versus cleanliness dictates this choice.
Weight
Product A, the Greenworks mower, weighs 37.5 pounds. Product B, the Litheli mower, weighs 33.1 pounds. The Litheli is lighter by 4.4 pounds. This weight difference may affect how easily you can push and maneuver the mower, especially on slopes or uneven terrain. The lighter Litheli might feel less strenuous to operate for extended periods. The Greenworks, while slightly heavier, may offer more stability during operation. Both weights are manageable for most users, but the Litheli’s lower mass could be a benefit for those with limited strength or mobility. Consider your physical comfort and the terrain of your yard when evaluating this spec.
Which mower fits your yard size
Small yard owners needing extended runtime
The Litheli mower features an 8.0 Ah battery that provides up to 40 minutes of fade-free power. Its 14-inch cutting width is ideal for smaller spaces. The brushless motor offers zero maintenance and quieter operation. You can tackle mid-sized yards efficiently without worrying about frequent battery swaps or noise complaints from neighbors.
Users preferring a wider cutting deck
The Greenworks model offers a 16-inch cutting width, covering more ground per pass than the 14-inch alternative. It includes a 4.0 Ah battery and charges quickly. The 2-in-1 system allows you to mulch clippings or use the rear bag. This setup suits those who value a broader swath and versatile clippings management for their lawn care routine.
Those wanting mulching capability included
If you prefer to leave clippings on the lawn, the Greenworks mower supports a 2-in-1 mulch and bag system. The 16-inch deck helps distribute clippings evenly. While the 4.0 Ah battery is smaller, it is sufficient for up to one-third acre depending on grass conditions. You get a proven system with a 3-year warranty on the tool.

Frequently asked questions
Does a higher Ah battery mean the mower lasts longer?
Yes, a higher amp-hour rating generally extends runtime. The Litheli mower includes an 8.0 Ah battery, while the Greenworks model uses a 4.0 Ah unit. This difference allows the larger battery to provide more continuous cutting time before needing a recharge, which is helpful for larger tasks.
Which mower is better for small lawns under a third of an acre?
The Greenworks 40V 16-Inch Push Lawn Mower is ideal for small yards. It features a 16-inch cutting width and weighs 37.5 pounds. Its 4.0 Ah battery provides adequate power for modest lawns without the extra weight of a larger battery pack, making it easier to maneuver in tight spaces.
Is a brushless motor worth the upgrade in a cordless mower?
A brushless motor offers zero maintenance and consistent performance. The Litheli 14-Inch model uses a brushless design, which reduces wear and tear compared to brushed alternatives. This feature supports its role as a low-maintenance option for users who prioritize reliability and extended runtime over a wider cutting path.
How does cutting width affect mowing efficiency?
A wider cutting path reduces the number of passes needed. The Greenworks mower offers a 16-inch width, while the Litheli model provides a 14-inch width. If you have a larger area, the wider deck covers more ground per pass. For smaller yards, the narrower deck may offer better maneuverability.
What is the weight difference between these two mowers?
The Greenworks mower weighs 37.5 pounds, and the Litheli mower weighs 33.1 pounds. The Litheli model is lighter, which can make it easier to push and store. However, the Greenworks model includes a 16-inch deck, which may add slight bulk compared to the 14-inch deck on the Litheli unit.
Do these mowers require a specific voltage battery?
Both mowers operate on a 40V power system. The Greenworks model uses a 4.0 Ah battery, and the Litheli model uses an 8.0 Ah battery. You must use batteries compatible with the 40V platform. Ensure your existing batteries match this voltage to power either mower effectively.
