A clearing apparatus comprising a clearing device for use in clearing operations, a carriage to which the clearing device is mounted for the carriage to support the clearing device during use, and a handle for use in guiding the apparatus during use. The clearing device comprises an elongated support member, a clearing head mounted at a leading end of the support member, a power unit mounted at a trailing end of the support member, and a drive connection for connecting the power unit to the clearing head. The carriage comprises a frame, a single support wheel having a wheel axis about which the support wheel is rotatably mounted on the frame to support the frame during use, and a pivot mount mounting the clearing device to the frame such that the clearing apparatus can be supported proximate its center of gravity on the support wheel during use. The pivot mount has a pivot axis extending generally parallel to the wheel axis, and the clearing device is pivotally displaceable about the pivot axis for adjusting the position of the center of gravity of the clearing device relatively to the wheel axis. The carriage has a locking device for locking the clearing device relatively to the pivot mount in a desired adjusted position. 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.
