Abstract: A stabilizing roller for a line trimmer device that includes a housing with a cylindrical bore for receiving and mating with a ball roller. The lower end of the housing is open to allow the ball to contact the ground while in operation. The ball is maintained in the housing on the lower end using either an integral lip or a removable retaining plate. The upper end of the housing is closed with a cap designed to mate with the ball during operation. Thus, the ball is free to roll. The housing is connected to a line trimmer device by either a bolt attached to the head of the line trimmer device or a frame and attachment means connected to the extension arm of the line trimmer device.
