A more advanced model with higher capacity. Manages both mowing and charging automatically and is suitable for areas up to 1/2 acre. When the battery needs recharging the mower returns to the charging station, charges and then continues mowing. Since this model cuts the grass so frequently, the result is excellent. Using the settings via the keypad and display, the mower can be adjusted to do a first-class job even on lawns with a complicated shape. Installation kit not included.
