The “RoboCut” creates a connection of the spindle cutting system (precise “shear-like” gumption system) with most modern technology, comfort and automation. After installation of the delimitation loops the mower can be set off in the grass after very easy programming by simple, gradual and easy menu guidance and cuts in pre-programmed cycles. When it rains, the integrated rain sensor signals a go back in the base station. A ultrasonic warning sensor system allows the early recognition of suddenly arising obstacles.
