I am going to buy a new string trimmer here shortly and was wondering which one to buy. I want the best "advance the string" head out there... I currently have a 20+ year old Stihl curved shaft that runs super but every once in a while the string wedges or binds inside the head and won't advance too easily. I want one with more power also. Possibly one to put a circular saw blade on it for cutting trees (small). Any body have a favorite on that's the best... in their opinion? I do apologize If I have asked this before.... memory ain't the best. Thanks

Get a wheel trimmer.

Stihl. Have 2 and both have performed flawlessly. Eric

And the bigger in size the better. I have the combo unit with 4 different attachments.

I bought a Stihl FS94R five years ago. It's the same as your older one; runs great but the string binds occasionally.

Echo straight shaft seems to be most popular with the local lawn services.

MY echo just died. took it 25 years to do it!

Must be a Nebraska thing.....

Shindiawa. They build a great string trimmer. Various sizes and attachments . i have seen many pro lawn care folks running them. The one I purchased is the right below the commercial grade trimmer. Easy to operate, Powerful and no problems. Check them out.

Go with a Stihl commercial grade string trimmer. I believe I went with one of the bigger sizes (can't remember the model) before they made the jump to the bike handle models.
