Shield apparatus for power trimmer

摘要

A shield apparatus for use with a powered vegetation trimmer of the type including a trimmer head assembly having an output shaft and a cutting mechanism rotatable with the output shaft. The shield apparatus is mounted coaxially about the output shaft between the cutting mechanism and a head portion of the head assembly. The shield includes first and second outer walls coaxially disposed about the axis of rotation of the output shaft. The first outer wall circumscribes at least a portion of the cutting element to define a distal annular gap. The second outer wall circumscribes at least a portion of the head portion of the head assembly to define a proximal annular gap. The shield isolates the output shaft from the area surrounding the cutting mechanism so as to prevent vegetative matter from contacting the output shaft, or at least minimize such contact.
