Abstract: An outdoor tool includes a powerhead, a tool unit powered by the powerhead, and a shaft assembly extending between the powerhead and the tool unit. The tool unit includes a transmission housing, a support plate, a guide bar adjustably supported by the support plate, a drive gear, and a chain circumscribing a portion of the drive gear and a portion of the guide bar, the drive gear operatively coupled to the powerhead. The tool unit further includes a tension adjustment mechanism for adjusting a position of the guide bar relative to the drive gear to increase and decrease a tension in the chain. The tension adjustment mechanism includes an adjustment screw, a threaded adjustment bolt, at least one adjustment gear, and a member coupled to the adjustment bolt and the guide bar. Rotation of the adjustment screw causes translation of the guide bar relative to the drive gear.

Abstract: 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.

Abstract: A snow blower may include a frame, a rotatable auger, one or more wheels, and a chute body. The frame may define an inlet opening and an outlet opening. The outlet opening may be circumferentially bounded about a chute axis. The rotatable auger may be mounted to the frame rearward from the inlet opening and below the outlet opening to motivate snow to the outlet opening. The one or more wheels may be mounted to the frame apart from the rotatable auger to support the snow blower. The chute body may extend from the frame along the chute axis above the outlet opening.

Abstract: A powered device includes a powerhead unit and an attachment unit selectively attachable to and powered by the powerhead unit. The powerhead unit includes a motor, a first shaft segment having a first driveshaft segment coupled to the motor, and a first connecting portion attached to the first shaft segment. The attachment unit includes an operational unit configured to be driven by the motor, a second shaft segment having a second driveshaft segment coupled to the operational unit, and a second connecting portion attached to the second shaft segment for coupling to the first connecting portion. One of the first connecting portion and the second connecting portion defines an axial opening having a keyway and includes a button having a hook portion. The other of the first connecting portion and the second connecting portion defines a slot and includes a key.
