Best petrol lawn mowers
Petrol still earns its place on large, rough or remote lawns where runtime beats convenience. Engine size is the headline spec buyers compare, so these sourced petrol models — push and self-propelled — are ranked by engine displacement, largest first.
How we rank: petrol mowers with a sourced engine size, ranked by displacement (largest first). These are transparent sorts on sourced specs — we don't publish editorial scores until they're defensibly sourced. Blanks mean "not specified", never a guess.

FAQ
Does a bigger engine mean a better mow?
Not on its own. A larger engine helps in long, wet or tough grass and drives wider decks without bogging down, but cut width, build quality and self-propulsion matter just as much. Match the engine to your conditions rather than chasing the biggest number.
Why are some prices blank?
We only publish a price once it's sourced for the local market. A blank means "not specified yet", never an estimate — check the linked retailer for the current figure.
