What is a split shaft trimmer?

Did you know that you can convert some weed eaters into another tool?  These trimmers are known as split shaft trimmers. You may have one stored away in the garage and not even know it.

An easy way to identify a split shaft trimmer is by examining the shaft itself. All split shaft trimmers feature a coupler system located in the middle of the drive tube. This system gives you the ability to interchange a series of attachments. Therefore, eliminating the need to back around several tools.
