I have used the Bosch rental electric jackhammers for removing tower bases.
Well .. sort of ... I remove down about 2-3 feet of concrete, the hammer
also "cut" the legs of the Rohn/whatever bases .. and then .. take out the
debris, and dirt is shoveled over the whole enchilada .. a little grass
seed, and ... VOILA .. the tower is gone .. until someone in future years
decides to Rototill the yard .. but, whatta hey. So .. should work as Al
sez... Mark AA6DX
