ABSTRACT:
A practical and safe heavy duty hedge, bush and brush cutter having a forwardly mounted dual-sided tine set that comprises a means for readily cutting flexible heavier limbs. The forwardly mounted tine set preferably is part of a comb-like attachment which includes a number of additional dual-sided tine sets that define a plurality of gathering, holding and cutting areas. The attachment is designed so that it can be mounted from one side of a conventional chain saw blade without removing the chain blade from the chain guide and yet provides stopping surfaces on both sides of the guide bar and chain blade of the saw to support severed limbs and branches in such a manner that bias cutting of flexible limbs and shredding of branches is prevented. The comb-like attachment including the dual-sided tine sets defining the gathering, holding and cutting areas for branches to be cut can be installed and removed from one side of the chain saw blade without the use of special techniques or tools.
