Consistent turf finish: The 38 cm cutting width role

The 38 cm cutting width combined with a six-step central height adjustment (25–75 mm) ensures each pass overlaps neatly, reducing missed strips and uneven lengths. Large wheels and a stable deck keep blade height steady across typical garden contours.

Keep mowing runs efficient and predictable, producing a uniform finish across the lawn after a couple of passes.

Does the Power X-Change battery system live up to the hype?

With two included 4.0 Ah Power X-Change batteries and the Power X-Twincharger, swapping packs between tools becomes straightforward and both batteries can be recharged together. By using the shared battery platform, the same cells power other garden tools for sequential tasks without extra chargers.

Interchangeable batteries cut downtime during a weekend tidy-up and the Twincharger returns both cells to ready status for the next session.

The Impact of the brushless motor on your daily mowing

A brushless motor reduces internal wear and draws current more efficiently than carbon-brush alternatives, which preserves usable runtime per charge and lowers maintenance needs. The smoother power delivery keeps blade speed steady under varying grass thickness.

If you mow on a schedule, the brushless drive keeps run times consistent across back-to-back cuts and avoids the usual mid-job power sag.
