My intial plan was to get the Kombi system. I told my dealer what I was using it for but she said it wouldn't have enough power. Thanks for advice I think I'm gonna go forward with it. My next question is should I go with the Kombi or the Echo version? My dealer said the Echo is better but she might just be making more money on that unit.
I went with the km131. It is the most powerful power head stihl offers. I have never found it lacking in power. It has more power than i have to hang onto it sometimes. I'd highly recommend it.
I cant speak to the echo.
Fyi the power broom paddles and tiller tines are interchangeable. No need to buy two full attachments. I bought the power broom attachment and then picked up the tines separately. Saves money going this route.
