ABSTRACT:
A shield and structure for mounting the shield to a hand held grass trimmer is provided. The generally flat shield is perpendicularly mounted to a gear box extension which is carried coaxial with the drive shaft tube. Twisting and moment forces incurred by the shield when the trimmer is resting on the ground are reduced by mounting the shield to support the weight of the trimmer generally perpendicular to the length of the drive shaft tube. The mounting structure prevents sliding of the shield on the drive tube and provides multiple attaching members to prevent rotation of the shield on the drive tube.
