The choice between electric and petrol comes down to garden size, lawn complexity, and personal preference. Here is a straightforward comparison.
Electric Lawn Mower
Pros: Lighter, quieter, lower maintenance, instant start, no fuel costs.
Cons: Limited by cable length or battery charge. Less powerful for thick grass.
Best for: Gardens up to 400m², flat lawns, light to medium grass.
Petrol Lawn Mower
Pros: More power, no cable, longer runtime, better for thick or wet grass.
Cons: Heavier, louder, more maintenance, fuel costs.
Best for: Gardens over 400m², slopes, thick or coarse grass.

I'd add that electric mowers with lithium-ion batteries offer better performance than lead-acid ones. Look for one with at least 4Ah capacity if you're near your battery's limit.
Thanks for the comparison. However, could you clarify why petrol mowers are considered better for gardens over 400m²? I've had no issues with my electric one on a similar sized lawn.
I'm still unsure which one to choose for my half-acre garden with quite a few slopes. The electric's instant start is tempting, but I worry about being limited by cable length when tackling those hills.
I've found electric mowers with lithium-ion batteries offer longer runtime than lead acid ones, closing the gap in this debate for larger gardens.
I've always wondered, does the cable length of electric lawn mowers usually stretch far enough to reach my entire 350m² garden?
I've got a smallish garden around 300m². Would you recommend electric over petrol for that? I'm keen on the lower maintenance.
I understand electric mowers are lighter and quieter, but I'm surprised they're supposedly less powerful for thick grass. Could you elaborate on why that is?
I appreciate the comparison but I'm unclear about the runtime of electric models. How long does it take to recharge the battery and is that enough for gardens larger than 400m²?
