A trimmer apparatus comprising a trimmer device for use in trimming and edging operations, a carriage to which the trimmer device is mounted to support the trimmer device during use, and a handle for use in guiding the apparatus during use. The trimmer device comprises an elongated support shaft, a power unit mounted at a trailing end of the shaft, a trimmer head mounted at a leading end of the shaft, and a drive connection for connecting the power unit to the trimmer head. The trimmer head has a trimmer blade to operate in a blade plane. The trimmer device has a swivel connection to allow the trimmer head to be swiveled between a trimming position where the blade plane is generally parallel to a support surface supporting material to be trimmed during use, and an edging position where the blade plane is generally at right angles to such a support surface during use. The carriage comprises a frame, and a single support wheel rotatably mounted on the frame to support the frame during use. The trimmer device is mounted to the carriage such that the trimmer apparatus will be supported proximate its center of gravity on the support wheel during use. The handle is positioned for an operator grasping the handle for guiding the apparatus during use, to be positioned to one side of the support wheel and at least partially in line with part of an axial projection of the support wheel during normal use. The blade plane in its edging position is substantially parallel to and generally in line with the plane of the support wheel.
