About this product

The Challenge 31cm is a compact, cordless rotary lawnmower designed for small lawns. Cordless power lets you cut anywhere without the danger of cutting the cable. The motor and carbon steel blade combine to effortlessly cut through tough, dense grass. Height adjustment is easy, and you can choose from five cutting heights (25-65mm) by easily unscrewing each wheel by hand, no tools required. This lightweight (8.9kg), easy to use mower offers cord free convenience for lawns up to 100m2.

The 18V 4.0ah detachable battery will give you up to 20 minutes runtime, enough time for most small UK lawns. The battery is detachable, and the charger is included, so you can charge the battery anywhere - not just in your shed or garage.

The mower comes supplied with a 30L collection bag, which has a handy grass full indicator to let you know when it needs emptying.

For user comfort, the upper handle is adjustable to 2 different positions and, when not in use, it folds down easily, so you can store it in smaller spaces.
