Cutting tool and work machine

A cutting tool for clearing plant growth, the clearing tool comprising:

• a power transmission apparatus;
• an elongated part coupled to the power transmission apparatus to rotate around a longitudinal axis of the elongated part and having at least one thread that rise toward the power transmission apparatus and the diameter of which decreases from an end of the elongated part coupled to the power transmission apparatus to the end of the elongated part that is at a distance from the power transmission apparatus;
• guide parts arranged around the elongated part to extend in the direction of the longitudinal axis of the elongated part;
• and
• a blade part arranged at the end of the elongated part coupled to the power transmission apparatus,
• wherein the elongated part, which, while being targeted in a longitudinal direction toward the plant growth, is arranged to cut the plant growth when being rotated in the plant growth by the power transmission apparatus, wherein the threads transport the plant growth toward the blade part guided by the guide parts and cut the plant growth with the blade part, and
• wherein the power transmission apparatus includes an adjustable transmission, and the adjustable transmission comprises at least two transmission positions corresponding to different trunk diameters.
