No Brainer Trimmer Head - 32307

[BigCTM]

This head looks like the easiest one to change that I have seen. Will this work on a Stihl FS46? It says it will fit 95% of the curved shaft trimmers on the market. Thanks.

Yes it will

I have the no brain trimmer head and I do not believe it will work on the Stihl FS46. If you look at the instructions that come with the trimmer head (model 32307 for curved shaft trimmers), the Stihl has the long arbor shaft exactly like the example in the bottom right (the one that uses the spacer). However, the Stihl's arbor shaft is externally threaded, not internally threaded. Do not see how this is going to work...

Hi,
I apologize, you are right it will not work. Unfortunately, of all the competitor models, Stihl are the least likely to work with the No Brainer.
