Abstract Hedge trimming apparatus including a substantially horizontal platform pivotable along one edge of a base to level the apparatus relative to a hedge to be trimmed. Wheels and a handle are connected to the base to form a movable carriage for the apparatus. A vertically adjustable column on the platform and a horizontally adjustable shaft mounted on the column are provided to mount a bracket for retaining an electric hedge trimmer on the apparatus, whose position can be adjusted relative to the hedge by adjusting the position of the column and shaft, once the platform is levelled.
