How could you attach a chainsaw to a digger? :D

I'd look at using one off a Timber procceor / crane arm fitted with hydraulic drive. ;

or how about one of these, a simple shear & griper for small trees ?

I have something in mind. I got all the components and metal work needed from James Whiteman plant breakers locally. A grapple or a pulveriser could be modifed to become wood shears but I have a more cost effective idea in mind. Only spent £60 on materials so far. If I hadnt ran out of oxygen on New Years Day It would have been made by now. I'll keep you all posted.

Never seen a hydraulic ram tree shear before. Ive seen the "Feller Buncher" Giant Tree Shears that have the same grapple method but have a chainsaw blade that flips out to make the shear.

Heres a link to a screw type logsplitter attachment for diggers. However this thing costs mega bucks and is really poor value.

simple to attach a chain saw to a machine you are maybe unaware but a harvester head on a machine is basically a large chain saw :claphands: :claphands: :claphands: :claphands: :claphands: :claphands: :claphands: :claphands:

Problem with the chainsaw idea, as any tree harvester operator will tell you, is the minute the chain touches the ground or a mucky stump it's blunt and you're out changing it. That's why so many leave high stumps and cause the forwarders problems. :dizzy:

Many North American feller bunchers use shears for the cut, especially favoured in frozen timber too. The blades are designed to put the shatter caused by the cutting force into the stump, not the log, which is pretty clever. It helps with the stumps rotting too.

A local plant hirer had a hydraulic circular saw fitted to an ackerman 3 some years ago for reducing the height of his hedgerows on his farm. It seemed to work well but I bet a safety officer would n't like it!!!!!!! :lol: :lol: :lol:
