The Troy Built Hedge Trimmer Attachment Model TBAH was poorly designed and failed after the third time it was used. The design engineers failed to put any radius in the housing casting which created a shear point and almost guarantee of failure.
I expected to be able to trim my hedges more than three times prior to a failure. Since my hedges only get trimmed twice a year I have been left out to dry. Lowe's of course wants it's customers to procure additional insurance. I say why don't you build a product correctly and charge more for it than selling junk.
