Stihl FS90R, "circular saw" type blade?

[Joseph Acquisto]

Have a Stihl FS90R straight shaft weed wacker. Standard line trimmer head and a poly blade head. No bicycle handle. Works great, but need to clear "lots of overgrowth" and it is slow going with just that stuff and a Stihl 012av. Figured to try one of the "Chisel tooth" blades or a chain saw toothed blade.

Thoughts? I know these can be quite dangerous and Stihl says to use the bicycle handles and double harness, but figure if I go slow I can do OK.

Nope. If you go slow, it doesn't work.

If (when) that blade grabs something it WILL throw the week whacker. If you don't have double handles and a harness it could get ugly.

The chisel tooth saw blade is awesome for cutting woody brush and small trees, but as already stated, you really don't want to run that without bike handles and double shoulder harness. The Stihl large deflector is helpful, too.
