In a rotating grass trimmer, a top loading line blade and corresponding head securely hold the cutting lines with multiple orientations of the line blade. An alternative embodiment provides a simplified loading scheme where a cutting line is loaded into the trimmer head from its outside, through a line outlet to a fixed receiver without the need for a moving or mechanical line gripping or biting type mechanism. With this construction, a worn line can be replaced by pulling it back out or by reversing it back through the same outlet from which it was initially inserted. The design eliminates practically all of the costs associated with the current state of the art rapid loading mechanisms as there is no physical compression, gripping or biting into the line by any mechanical or moving mechanism. Additionally, the line is insertable in multiple orientations.
