Abstract: A lawn trimmer shield (10) for protecting trees, plants and the like against damage from being struck by the rotating string (13) of a lawn trimmer/weed cutter (12) is disclosed. The shield (10) comprises two wall sections (14 and 16) of hollow substantially semi-cylindrical shape which are hingably connected via a hinge (17). Each of the wall sections has a chamfered ground engaging edge (26 and 28) which facilitates trimming close to the ground adjacent the shield (10). Handles (30A and 30B) are provided for facilitating installation and removal of the shield (10). Spikes (32A and 32B) are provided proximate the ground engaging edge (26 and 28 ) for securing the shield (10) close to the ground when it is installed about a tree (11), plant or the like.
