Abstract: A clutch arrangement for a motor driven chain saw having a first clutch element driven by the motor shaft and a second clutch element normally engaged with the first clutch element but disengageable therefrom and a centrifugal clutch between the second clutch element and the drive sprocket for the saw chain. The second clutch element includes a spring disc and is axially yieldable between clutch engaged and clutch disengaged positions. A lever is provided moveable for disengaging the clutch elements and a brake member connected to the lever is operable for braking the drive sprocket when the clutch elements are disengaged.
