# How to Thread a Shindaiwa T242 Weedeater
The trimmer head that houses the string on the Shindaiwa T242 weed eater is a sealed, rewound unit. Once the string is gone, you simply replace the head. This means you do not have to thread the string onto the bobbin inside the cutter head. This simplifies the process and makes changing the string something you can accomplish quite quickly.

- New trimmer head
