ABSTRACT:
A cutting apparatus for a lawn mower includes a base plate that has a side surface which is formed with two guiding blocks and an abutment post. The abutment post is disposed between the guiding blocks. A nylon line has two block-engaging line portions received respectively within slots in the guiding blocks, a curved post-engaging line portion abutting against an annular surface of the post, and two generally straight connecting line portions connecting the block-engaging line portions respectively to the post-engaging line portion. One of the block-engaging line portions forms an acute angle with an adjacent one of the connecting line portions so as to prevent the nylon line from being removed from the guiding blocks by the centrifugal force of the nylon line when the base plate rotates.
