Abstract: A chainsaw including a lubrication system and guide bar extend from a housing. The lubrication system includes a reservoir at which a lubricant is contained. The reservoir is releasably attachable to a machine drive device. The machine drive device includes a body at which a pump apparatus is positioned. The machine drive device forms an inlet opening in fluid communication with the reservoir. The machine drive device forms an outlet opening at which a conduit is fluidly coupled to receive the lubricant. The conduit forms a conduit outlet through which the lubricant is provided to the guide bar.

Abstract: An accessory mount device for a power tool, wherein a reference axis forms an axis of rotation of the accessory mount device, the accessory mount device including a housing forming an interior volume, the housing including a ramped surface in the interior volume at which a bearing is positioned; a first plate forming a channel at which the bearing is positioned at the ramped surface to push the first plate along the reference axis; and a second plate configured to push a spool in the direction of the reference axis, wherein the bearing is configured to selectively push the first plate to the second plate when a centrifugal force threshold is exceeded, and wherein the second plate is allowed to rotate around the reference axis separate from the first plate.

Abstract: Quick release blade assemblies for a power tool are provided. A lawnmower includes a base including an engagement interface; a retainer having a locking component; a blade disposed between the base and the retainer; and an actuatable member including an engagement member, the engagement member being selectively displaceable with respect to the engagement interface between a locked configuration and an unlocked configuration when the actuatable member is translated in a direction parallel with the axis of rotation, wherein the engagement member is configured to interface with the locking component to selectively couple the blade to the drive shaft when the engagement member is in the locked configuration.

Abstract: A chainsaw and a drive system therefor are provided. The drive system includes a motor operably coupled to drive a motor shaft and an output drive operably coupled to an output shaft. The motor shaft and the output shaft are mechanically coupled to one another by a transmission system to transfer energy from the motor to the output drive. The motor and motor shaft are coupled to a housing. The transmission system allows the output shaft to selectively change positions along a circumferential direction relative to a rotational axis of the motor shaft to selectively loosen or tighten a connection of the output drive to a chain at a guide bar.

Abstract: A blower vacuum, the blower vacuum including a nozzle forming a first opening, a fan housing in fluid communication with the nozzle, an inlet exhaust housing rotatably coupled to the fan housing, and a debris housing. The fan housing forms a second opening. A fan assembly is positioned at the fan housing. The inlet exhaust housing includes an inlet portion and an exhaust portion. The inlet exhaust housing is rotatable to a first position forming a blower operation and a second position forming a vacuum operation. The debris housing is coupled to the exhaust portion of the inlet exhaust housing.
