The innovative GARDENA robotic mower R40Li does your mowing for you: it mows the lawn on its own, while you enjoy your free time or do other things. Thanks to its irregular pattern, the R40Li mows a lawn area up to a maximum of 400 m² – effectively, reliably and without wheel ruts. Always resulting a perfectly cared-for lawn. When required, the robotic mower recharges itself at the charging station. Its easy-to-place boundary wire shows the R40Li where to mow. It repeatedly cuts grass tips with razor-sharp blades; grass clippings remain on the lawn as a natural fertiliser (mulch principle). The cutting height of 2 to 5 cm can be easily set with a rotary knob. With a weight of eight kilograms, the robust robotic mower tackles inclines up to 25 %. Programming is incredibly simple and quick. Different mowing times or days can be set on the large selection panel and display. Following the menu is easy and intuitive. After programming, the R40Li starts on its own at the set times, even when it rains. The powerful and easy-care lithium-ion 18 V /1.6 Ah battery ensures reliable and energy-saving operation. The R40Li also works very quietly and without emissions. Highly sensitive collision sensors and the boundary wire help the R40Li to avoid obstacles in the garden. Lift and tilt sensors, and a large space between the housing and blades, guarantee additional safety for people and animals. For example, when the mower is lifted, the blades immediately stop and thereby prevent injuries. The robotic mower can also be stopped at any time with the large, easy-to-access stop button. R40Li is flexible and therefore well suited for nearly any garden type, as well as for example secondary areas. The robotic mower is supplied with a charging station, a power cable, boundary wire, staples, spare blades, couplers and connectors.
