Our verdict
Punches above its weight on cut width and deck quality. The engine is the weak link — capable but not premium. Good value new, fair value used. The smarter buy than a Webb at £30 more.

- Self-propelled with 3-year warranty

Buying second-hand
£90–150 used. Steel deck means rust is the killer — flip it and inspect the underside thoroughly. Engine starts can degrade over winter; ask the seller to fire it from cold. Generic engines have no real brand value but Hyundai parts are available.
