Rank #6 in Best Petrol Lawn Mowers 2026: 10 Ranked, Ad Claims Checked
Q Garden QG40-145SP Self-Propelled 40cm Petrol Mower
Price and rating as shown on Amazon when we collected them. Both change.
The Q Garden QG40-145SP is a four-wheel, self-propelled petrol rotary mower listed at £148.00. It takes number 6 in this guide of 15 petrol mowers, with a 4.2 out of 5 rating from 299 ratings. The listing gives it a 141cc OHV four-stroke engine, a 40cm cutting width, seven cutting heights from 25mm to 75mm on a single lever, and a 45 litre collection bag that lifts out through the handlebars.
The awkward part is not the price or the capacity — it is the spec table underneath. The same page that calls this mower self-propelled files its Operation Mode as "Manual", describes a machine it sells as metal-bladed as being made of Acrylonitrile Butadiene Styrene, and ticks "Is Assembly Required? No" while a buyer on that page writes about putting it together. Everything below comes from the Amazon listing itself, not from any test we ran.
