I am looking at getting a TBC-230SF. I notice it is rated at 1.1 hp. I have a stihl FC75 edger which is rated at 1.27 and the engine is 25.4cc. This edger in my oppinion is way under powered. If we have to edge something thats a little over grown over the sidewalk I have to work it back and forth because it bogs down. In other words is the TBC-230SF going to be the same or even worse with the edger attachment considering its rated at less power than Stihls lowest model edger?
