Features

Standard features

  • Standard equipment Zoom
    Standard equipment

    The standard equipment of the STIHL iMow robotic mower includes the machine, the docking station, four pegs for fastening the docking station to the ground as well as an iMow ruler as an aid for laying the perimeter wire. iMow is installed by authorised iMow Dealers only.

  • Bright LCD display Zoom
    Bright LCD display

    The control panel is integrated into the housing of the STIHL iMOW® robotic mower and features a large LCD display. It provides a particularly intuitive way of recording all settings as well as a way of viewing all functions and performance data of the automatic lawn mower. The high-contrast, bright display is easy to read even in sunlight.

  • Docking station Zoom
    Docking station

    The docking station is included in the standard equipment of the STIHL iMOW® robotic mower. It is both the robotic mower's home and where it charges its battery. At the same time, it is the starting point for every mowing operation. When driving, the automatic lawn mower is guided by the signal transmitted by the perimeter wire at the edge of the lawn. This signal is fed via the docking station. If it rains or the battery runs down during mowing, the iMOW® robotic mower independently returns to the docking station and recharges its battery. Thanks to its intelligent charging system, the iMOW® decides independently whether an express charge is necessary due to another imminent mowing operation or whether the battery should be charged more gently in normal mode. The docking station can be placed within or outside the lawn area.

  • Mulching mowing deck Zoom
    Mulching mowing deck

    The sturdy mulching blade of the STIHL iMOW® robotic mower ensures a precise cutting pattern even with higher grass growth. Its rotational direction changes automatically every time the blade stops. This means that the blades of the automatic lawn mower wear evenly. It is located together with the cleaning disc in a mowing deck. The blade can be changed without the need for tools.

  • Adaptive slope speed Zoom
    Adaptive slope speed

    Using the adaptive slope speed function, the STIHL iMOW® robotic mower adapts its speed on uneven terrain. The integrated tilt sensor constantly analyses the inclination of the automatic lawn mower and synchronises its propulsion.

  • Dynamic mowing plan Zoom
    Dynamic mowing plan

    Using the interactive mowing plan of the STIHL iMOW® robotic mower, individual time windows during which the machine can be in operation can be defined for each day. Within these active times, the automatic lawn mower automatically determines the best times to mow for an optimum result. If it has to interrupt mowing because of rain, for instance, it automatically catches up later within the specified time window. The dynamic mowing plan can be called up and executed via the control panel.
