This cordless mower delivers a fantastic cut on all grass types and handles difficult terrain, such as sloping and bumpy ground, well, too. Its self-propulsion and adjustable speed controls make it easy to manoeuvre, and the grass-collection box fills up to an impressive 90% of capacity before it needs emptying.

This feature-packed petrol-powered mower comes complete with a roller, variable speed control and deck wash attachment for easy cleaning. It’s easy to use and leaves a brilliant tidy finish on all grass types, though it struggles slightly on uneven and sloping ground, so is best suited to mowing flat lawns.

Which? tests around 3,300 products every year, from washing-up liquid to cars. When testing lawn mowers, we measure how well each one cuts grass – from short, ornamental lawns to long meadow grass. We also time how long it takes to cut the grass, how well the mower collects the grass clippings, how neat it leaves the lawn edges and how smart the finished lawn is. Our experts also rate each lawn mower on how easy is it to use.
