According to me The Bosch Rotak 34 electric rotary lawnmower is best.It has a high torque 1400W ‘Powerdrive’ motor that enables it to tackle long grass with ease. With the innovative grass combs it can cut up to or over the edge of your lawn. It has a full 34cm cutting width, a rear roller for stripes and a wide range of cutting heights from 20 to 70mm, making it ideal for small- to medium-sized lawns.
