Why Buy the Bosch Rotak 18V2-43?
Large 43cm Cutting Width
The 43cm cutting width helps you cover more grass with each pass, making this mower better suited to medium and larger gardens than smaller cordless models. If your lawn takes too long with a compact mower, the Rotak 18V2-43 is the logical step up.
2 x 18V Cordless Power
The Bosch Rotak 18V2-43 uses two 18V batteries together to deliver the performance needed for larger cordless mowing. That gives you cable-free movement around beds, trees, borders, sheds and garden furniture while still providing the power required for regular lawn maintenance.
Brushless Motor for Efficient Cutting
The brushless motor is designed for efficient power delivery, helping the mower maintain strong cutting performance while reducing wear compared with traditional brushed motor designs.
50L Grass Collector
The large 50L grass box means fewer stops to empty clippings, which is especially useful when mowing bigger gardens. The larger collector also suits customers who prefer a clean collected finish rather than leaving grass cuttings behind.
30–75mm Cutting Height Range
With 6 central cutting height settings from 30mm to 75mm, you can raise the cut for longer grass or tougher conditions and lower it when you want a neater finish during the main mowing season.
Bosch Syneon Technology
Bosch Syneon technology helps manage the energy demand while mowing, balancing power and runtime depending on the cutting conditions.
