A housing of the assembly is connectible to the engine unit and rotatable in a cutting plane. A reel is engageable with the housing, and has a reel portion, and a peripheral wall portion separately connected to the reel portion and having at least one aperture. At least one flexible cutting line is wound on the reel portion and has a free end portion extending outwardly of the housing through the at least one aperture. A cover covers the reel in a fashion holding the reel between the housing and the cover. A coupling device couples the cover to the housing in a fashion clamping the reel securely to the housing. Urging protuberances are provided on the covering for urging the reel portion to forcibly separate the reel portion from the peripheral wall portion when the covering is coupled to the housing.
