Abstract: A flexible nonmetallic line trimmer for cutting vegetation has a wheel support for edging operations. The trimmer has a safety guard that extends around the rearward portion of a motor housing. A sliding bracket is mounted to the safety guard. A wheel is mounted on the forward end of the sliding bracket. The bracket will slide between a retracted position with the wheel to one side of the housing to an extended position with the wheel in front of the housing to support the cutter.

Abstract: A line trimmer for cutting vegetation has features to enable automatic advancement of line increments while rotating. The trimmer has a housing with an aperture on its periphery. A spool coiled with a flexible cutting line is located in the housing. The free end of the line extends out the aperture into a cutting plane. A set of drive members are located in the housing near the center in a circular array. A drive link is carried in the housing radially outward from the drive members. The drive link will move into contact with the drive members to lock the spool and housing together for rotation. Increased centrifugal force urges the drive link outward, allowing the spool and housing to slip relative to each other to feed out additional line. Stop members are located on the inner side of the housing outer wall. These stop members stop further slippage and force the drive link back into engagement with the drive members.
