Abstract: 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.

Abstract: A power tool may have features for varying height or speed. The power tool may include a base chassis, one or more wheels mounted to the base chassis, and a handle frame attached to the base chassis. A slider assembly or support rail may further be included with the power tool to, for instance, aid in varying speed or height.

Abstract: A power tool may include a power tool housing. A power tool may include a drive unit located within the power tool housing. A power tool may include a power tool controller located within the power tool housing, the power tool controller configured to: receive a signal from battery pack, the signal indicative of a temperature of the battery pack, and do not limit a drive unit power if the temperature is less than a temperature threshold.

Abstract: A power tool system including a battery pack and a power tool. The power tool includes a power tool housing, a drive unit located within the housing, and a power tool controller located within the housing. The power tool controller is configured to receive a signal from the battery pack (for example, a battery pack controller), the signal indicative of a temperature (for example, a temperature of the battery pack); determine whether the temperature is between a lower temperature threshold and an upper temperature threshold; and limit a power to a drive unit if the temperature is between the lower temperature threshold and the upper temperature threshold.

Abstract: A blade for a lawn mower includes a blade body, a longitudinal axis, a center opening, a first aperture, and a second aperture. The blade body has a first end and a second end opposite the first end. The longitudinal axis extends centrally along the blade body and through the first and second ends. The center opening is defined in the blade body and receives a drive shaft. The first aperture is defined in the blade body between the center opening and the first end. The first aperture receives a first projection. The second aperture is defined in the blade body between the center opening and the second end. The second aperture receives a second projection. The first aperture has a different shape than the second aperture. A centroid of each of the center opening, the first aperture, and the second aperture is substantially aligned with the longitudinal axis.
