Cutting assembly for a mining machine

A cutting assembly for a mining machine, said cutting assembly comprising:

• a central hub including at least one arm extending radially outwards from the central hub, wherein the at least one arm is provided with at least one cutting means carrier movably attached to the at least one arm for radial movement along the at least one arm, wherein the at least one arm is provided with a primary actuator configured to control a radial position of the at least one cutting means carrier;
• and
• a locking device movable between an unlocked position and a locked position, wherein the locking device in its locked position locks the at least one cutting means carrier to the at least one arm such that radial movement of the at least one cutting means carrier is prevented, wherein the locking device in its unlocked position allows movement of the at least one cutting means carrier radially along the at least one arm, the locking device including at least one locking member provided on the at least one arm such that the at least one locking member is movable between an extended position and a withdrawn position, wherein the at least one locking member in the extended position extends to engage the at least one cutting means carrier such that movement of the at least one cutting means carrier is prevented, wherein the locking device includes a biasing means configured to bias the at least one locking member towards its extended position.
