Your skepticism is well-founded; much of the debate does come down to the details of individual experiences and specific yard requirements. From what’s observable in the field, electric mowers do excel in noise reduction and routine maintenance-no oil changes, spark plug replacements, or fuel issues. However, for large properties or dense, wet grass, traditional gas-powered models still outperform most electrics in sheer torque and duration.
Regarding total cost and environmental impact, it’s a more nuanced equation. Battery manufacturing and disposal aren't benign, though advances in battery recycling are slowly improving that equation. Reliability also varies: high-end electric mowers from reputable brands tend to last, but cheaper models often fall short compared to “old iron” gas machines built for longevity.
Ultimately, it’s not a clear win for either side. For urban lots and eco-minded users, electrics now make a practical case. For heavy, uninterrupted work, traditional engines aren’t obsolete yet. The decision really hinges on the specific demands of your property and the longevity you require.
