<p>A drive mechanism for a chain saw has a minimal vertical height. The drive mechanism is particularly useful for timber harvesting vehicles, and includes a drive motor, a holder with a clamping mechanism for clamping a chain saw guide bar, a bearing assembly allowing the holder to rotate in relation to the motor and a swivel device to convey liquid from the motor to the guide bar through closed channels and grooves. The bearing assembly and the swivel device have openings having sufficiently large inner diameters such that the bearing assembly and the swivel device fit around the motor, thereby avoiding the need for mounting those elements on top of one another.</p> |
