A cutting tool (100) for clearing plant growth, such as a seeding stand, the cutting tool (100) comprising a power transmission apparatus (102) and an elongated part (104) which is coupled thereto to rotate around its own longitudinal axis and has threads (106) rising toward the power transmission apparatus (102) and having a diameter that decreases from the end (108) of the elongated part (104) coupled to the power transmission apparatus (102) to the end (110) that is at a distance from the power transmission apparatus (102), and guide parts (112) arranged around the elongated part (104) and extending in the direction of the longitudinal axis of the elongated part (104), and a blade part arranged to the end (108) of the elongated part (104) coupled to the power transmission apparatus (102), whereby as the power transmission apparatus (102) rotates the elongated part (104) in the plant growth, the threads (106) transport the plant growth toward the blade part guided by the guide parts. The cutting tool may be connected to a work machine.
