Question
I have a lot that is infested with river cottonwoods, as they are commonly known around here.  Suckers have erupted rather solidly along one fence.  I would like to turn this bunch into a hedge, but hedge trimmers don't have sufficient capacity or strength.  I have been using a small chain saw with limited success.  Some years back I saw a device that attaches to the chain saw bar to effectively make the saw a hedge trimmer.  None of the dealers in this area have this device, although a few recall that one existed.  Do you know where I might find one?  Thanks

Answer
It is going to depend on the make of chainsaw you have. each make has its own attachments and one will usually not fit another. I would call a chainsaw dealer that handle your saw. May even try a saw sharpener business/ repair shop they may be able to order one.
