发明名称 Trimmer attachment
摘要 A cutter attachment for a mono-filament type trimmer implement which includes a pivotal spacer assuring distance between the rotating string and the area under maintenance. Provision is made for readily mounting the attachment onto the implement and, as well, a locking arrangement serves to maintain the spacer in either an operative or a non-operative position. The configuration and/or design of the spacer permits selective movement in forward, rearward and lateral directions.
