A power cutting tool includes a housing, a motor accommodated in the housing, a cutting assembly optionally operated in a trimming mode or in an edging mode and being driven by the motor to rotate around a first axis, a handle assembly, an elongated shaft connecting the cutting assembly and the handle assembly, a guard mounted to the cutting assembly, and a wheel assembly including a wheel. The wheel assembly is optionally mounted at least a first mounting position and a second mounting position. The central axis of the wheel is substantially perpendicular to the first axis when the wheel assembly is mounted at the first mounting position and is substantially parallel to the first axis when the wheel assembly is mounted at the second mounting position.
