Hi Jodie,
There is a small hole or cutout in the side of the gearhead for you to insert a small screwdriver to hold the gears locked so you can unscrew the head clockwise looking at it from the bottom. These instructions are given in your owners manual which you can find here. http://www.weedeater.com/customer-support/user-manuals/
Hope this helps.
Regards,
Chip
