Cordless Lawn Mower FAQ
How big of a yard can a cordless mower handle?
It depends on battery capacity and lawn complexity. A single 4.0Ah battery on a 40V mower can typically handle up to 1/4 acre of flat turf. For larger areas (1/2 acre or more), look for models with dual batteries, larger 5.0Ah+ packs, or a quick-charge system to swap.
Is a brushless motor worth the extra cost?
Absolutely. Brushless motors are more efficient, providing longer runtime, more power, and greater durability with less maintenance. They are a key feature in higher-end models like the STEELITE 21V and MZK 40V for consistent cutting performance.
Can I use my existing tool batteries with a new mower?
Only if the mower is part of the same battery ecosystem. Brands like Greenworks design their 40V mowers to be compatible with dozens of other 40V tools. Always check the product details for "tool-free" battery compatibility before assuming.
What's the advantage of a self-propelled mower?
Self-propelled mowers, like the Greenworks 40V 21" model, do the pushing for you. This is a major advantage on hills, thick grass, or simply for reducing physical strain, making lawn care much less taxing, especially on larger properties.
