Rank #1 in Best Petrol Lawn Mowers 2026: 10 Ranked, Ad Claims Checked
FUXTEC FX-RM4646ECO 46cm 3-in-1 Petrol Mower
Price and rating as shown on Amazon when we collected them. Both change.
The FUXTEC FX-RM4646ECO is a 3-in-1 petrol mower: 3.5 HP (2.6 kW) 146cc four-stroke engine, 46 cm cutting width, seven cutting heights from 25–75 mm and a 50 L removable grass catcher. It sits at number one in this guide at £156.79, with a 4.4 average from 1,603 ratings — 74 of the ratings in Amazon's published breakdown are five-star against 7 one-star.
Its own advert is mostly consistent, which is worth saying on a page where several listings are not. The one number that does not agree with itself is weight: the bullet points describe a "lightweight petrol lawn mower (27 kg)", while the spec table lists an item weight of 28.8 kg — 1.8 kg apart in the same listing. The wheel figures are also split: the spec table gives a single 255 mm wheel size, while the bullets say 255 mm at the rear and 175 mm at the front. Cutting width (46 cm), cutting heights (7 positions, 25–75 mm) and the 50 L collector all match between the two halves. Everything on this page comes from the Amazon listing as published, not from our own testing.
