The purpose of the invention is to create a hydraulic driving and guiding assembly, namely a pulley, belt pulley or a chain wheel, and in particularly a pulley, which is driven by a hydraulic motor and is intended for unwinding a rope from the drum of a forestry winch, by means of which such unwinding of the rope (5) or a similar longitudinal towing member from the drum could be more efficient, and at the same time also to eliminate loosening of the rope (5) upon being unwound from the drum. For such purposes, a hydraulic driving and guiding assembly of a longitudinal towing member is created, which comprises a main driving member (1), which may rotate around the geometric axis (10) by means of a hydraulic motor (3) and is by means of bearings (41, 42) or similar bearing members embedded within an appropriate casing (2), wherein said main driving member (1) is connected positively in the sense of torque-transmission to a rotor (31) of a hydraulic motor (3), which rotor (31) is embedded within of said casing (2), while the stator (32) of said hydraulic motor (3) is firmly interconnected with said casing (2).
