A walk-behind mower has a mower deck, a plurality of wheels, a head, and a plurality of light sources. The wheels are rotatably coupled to the mower deck. The wheels move the walk-behind mower over a support surface in a forward direction and a rearward direction. The head is coupled to the mower deck. The head can store at least one battery pack. The light sources are coupled to at least one of the mower deck and the head. The light sources project light through a continuous illumination angle about the walk-behind mower. The illumination angle extends along an arc from the forward direction toward the rearward direction and is at least 90 degrees.

Selectable current limiting for a power tool. One embodiment provides a method for selectable current limiting for a power tool including determining, using a current sensor, an average current and determining whether the average current exceeds a predetermined current threshold. The method also includes determining a deviation of the average current from the predetermined current threshold and reducing a PWM duty ratio proportional to the deviation of the average current from the predetermined current threshold. The PWM duty ratio corresponds to a PWM signal provided to an inverter bridge.
