Zusammenfassung:LAWNMOWERS WITH SAFETY FEATURES AND METHODS ASSOCIATE THEREWITH A lawnmower comprising: a body; a cutting element coupled with the body; a motor configured to drive the cutting element; a sensor comprising an accelerometer configured to detect an angular displacement of the lawnmower with respect to a vertical axis and a wobble of the cutting element with respect to a horizontal plane; and a processor configured to: compare the detected angular displacement against a tilt threshold value; compare the detected wobble against a wobble threshold value; and control an operational speed of the cutting element when the angular displacement exceeds the tilt threshold value or when the wobble exceeds the wobble threshold value.
