Would a mechanical pulveriser crack and split tree trunks?

Depends on how much power you apply. I doubt if the Honda powered ones would, but this baby might:

Thinking of attaching it to to a 14 ton track machine. Shears would be better I know but they're like finding hens teeth.

Up here in Scotland there are a few about on, I think, 20 tonne machines, fitted with a donkey engine on the counterweight to drive the flail.

The stump harvesters (for power generation) now use a puller/splitter on excavators.

I do a lot of clearance work and in my experience pulverisor blades are too blunt to split timber and if they did it would n't be cost effective.

If you want too split wood and lots off it cheaply put a hydraulic splitter on a little old tractor. If its for a home fire I've seen some good cheap electric splitters but dont bank on making money with them commercially.

This is the type used for harvesting stumps, there are fleets of them working on biomass gathering and they ain't slow, the contractors on it appear to be making money.

They don't all use the second ram below the dipper.

Excellent video Dave. Do you know of any mechanical shears for sale?

Don't know if this may be of any help to you-a brochure i got from a show somewhere a few years ago.Hawkfawk is now owned by Baughans Barrel Screens-website - www.baughans.co.uk Tim

Heres another example http://www.bodinemfg.com/woodsplitter.html

Could a concrete pulveriser or grapple be made into a wood shear?

Hi William,

I would think it would be possible, but with quite a bit of work. When we had our fabrication workshop we did a lot of stranger things!

Best man to ask would be Northern Ireland member and master fabricator allistairc123.
