iMOW® RMI 422 robotic mower: automatically achieve the ideal lawn

General

RMI 422
RMI 422

If you want to mow a small to medium-sized green area on a fully automatic basis, the STIHL iMOW® RMI 422 robotic mower is a practical solution. Its mulching mower capability is powered by an integrated lithium-ion battery. During mulching, the lawn is only slightly shortened, and the very fine grass particles that result are evenly distributed on the turf; their valuable nutrients are returned to the soil as fertiliser, ensuring a dense and healthy lawn. With multi-level cutting height adjustment, your lawn is precisely cut to your preferred height – and thanks to Adaptive Slope Speed, that includes on uneven terrain with gradients up to 35%. Its robust hood protects the iMOW® from weather and obstacles. Integrated sensors register contact with an object and initiate a change of direction for the iMOW® robotic lawn mower. This compact power tool can be set up and organised in just a few simple steps using the control unit. The interactive mowing plan makes it possible to specify daily time frames during which the automatic lawn mower can be in operation. Within these active times, the power tool independently picks the best times for mowing to achieve an optimum result. An installation kit is required for installation. STIHL iMOW® robotic mowers adhere to all valid safety standards. However, the iMOW® robotic mower is not a toy, and children, spectators, and animals must be kept away from the work area during the iMOW® robotic mower’s active periods. For further information, please consult the user manual.

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. An installation kit is also required to install the iMOW® robotic mower.

  • ADAPTIVE SLOPE SPEED Zoom
    ADAPTIVE SLOPE SPEED

    FOR UNEVEN GROUND. The Adaptive Slope Speed function ensures that your robotic lawn mower can cope well even on uneven or steep ground. To achieve this, a slope sensor constantly analyses the slope and adjusts the speed of the robotic lawn mower accordingly.

  • iMOW® ROBOTIC MOWER DRIVE Zoom
    iMOW® ROBOTIC MOWER DRIVE

    HIGH PERFORMANCE EVEN ON SLOPING GROUND. iMOW® robotic mowers mow with consistently high quality, including on hilly terrain. Depending on the series, they can cope with even steep inclines.

  • MOVING HOOD Zoom
    MOVING HOOD

    PROTECTS AGAINST OBSTACLES AND WEATHER. If your iMOW® robotic lawn mower encounters an obstacle during automatic lawn mowing, the impact sensors integrated in the moving hood detect the object and trigger a change in direction. The robust material of the hood means the iMOW® robotic mower is also well protected against the weather.

  • MULCHING BLADES FOR ROBOTIC MOWERS Zoom
    MULCHING BLADES FOR ROBOTIC MOWERS

    AUTOMATIC LAWN FERTILISATION. The mulching blade lets you cut grass and fertilise it at the same time. It cuts the grass in stages and shreds the clippings into fine particles that deliver nutrients and moisture to your lawn. The specially shaped blades automatically change rotation direction each time the blade stops, ensuring even wear. Blades can be changed easily and without tools.

  • WHEELS WITH TRACTION PROFILE Zoom
    WHEELS WITH TRACTION PROFILE

    ENSURE PRECISE MOVEMENT ON TERRAIN. On hilly lawns and under difficult conditions, these wheels improve the traction of your robotic lawn mower. Whether on inclines, denser grass growth or a wet meadow, the traction profile of the smooth-running wheels means your robotic lawn mower moves with precision. The all-terrain profile wheels are also self-cleaning.

  • CONTROL CONSOLE LCD DISPLAY FOR ROBOT MOWERS Zoom
    CONTROL CONSOLE LCD DISPLAY FOR ROBOT MOWERS

    COMFORTABLE OPERATION. The control console is integrated into the housing of the STIHL iMOW® and has a large-format LCD display. The display is also high-contrast and bright, making it easy to read even in sunlight. In RMI 6 series models, it can be removed for more convenient operation. It is easy and intuitive to make changes to settings or the recording of performance data.

  • OFFSET SELF-DOCKING Zoom
    OFFSET SELF-DOCKING

    PROTECTS YOUR LAWN. By default the iMOW® robotic mower travels home to the docking station along the boundary wire. However, the robotic lawnmower can also be set to travel to the docking station along different paths. It also uses the installation wire in this process, though it moves over the lawn with the help of an alternating offset to the wire.

  • All-round protection Zoom
    All-round protection

    The STIHL iMOW® robotic mower is equipped with various sensors. As soon as someone attempts to pick it up while mowing, it stops. In addition, the automatic lawn mower can be protected with a PIN code. If it is configured so that it can only be operated by entering a PIN, it is protected from unauthorised use.

  • 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.

  • Control panel Zoom
    Control panel

    The control panel with integrated and bright display is used on all STIHL iMOW® robotic mowers for easy setup and fast display of machine information. The high-contrast display means the control panel can also be used in sunlight. The panel is flush-mounted in the housing of the automatic lawn mower.

  • 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.
