摘要： A dethatcher includes a frame having a front and a rear end, a handle coupled to the frame and movable between a use position and a storage position, multiple wheels coupled to the frame, a cutting reel housed in the frame, and an engine for powering a drive mechanism of the shaft. The cutting reel includes a shaft having a first end and a second end, at least one cutting mechanism located between the first end and the second end of the shaft, and the drive mechanism for powering the shaft. When the handle is in the use position, the handle extends away from the front end of the frame and when the handle is in the storage position the handle extends toward the front end of the frame.

摘要： A battery pack for powering equipment includes a core battery pack, a first housing, and a second housing. The core battery pack has a capacity of outputting a constant amount of current to deliver at least 1000 Watt-hours of energy. The core battery pack includes multiple battery cells and a mating interface. The mating interface is configured to selectively and electrically couple the core battery pack with an interface of a piece of power equipment or a charger. The first housing includes a handle and is attached to the core battery pack. The second housing is attached to the core battery pack and is configured to dampen a force experienced by the core battery pack upon an impact.

摘要： A dethatcher includes a frame having front and rear ends, a cover coupled to the frame and configured to selectively move between an open position and a closed position, a handle extending from the frame, multiple wheels coupled to the frame, a cutting reel housed in the frame, and an engine for powering a drive mechanism of the shaft. The cutting reel includes a shaft having a first end and a second end, at least one cutting mechanism located between the first end and the second end of the shaft, and the drive mechanism for powering the shaft. When the cover is in the open position, a user may access the cutting reel from a top end of the frame.
