Chain Saw Chopper

OK, this is not me. Ingenious, yet a bit scary.

Ideas OK as long as you keep your hands clear.

A modern version of a buzz saw. I like the throttle linkage. I think that took a bit of thinking to do, you need to locate and secure the saw, and the idea of hanging it on the cart edge, is very good.

Great way to take care of a lot of limbs. Like has been said - watch out for your hands. After use for a while, I can see a potential problem of the rhythm of cutting the limbs and your hands becoming involved with the blade.

Same counts for my Mottimaster, but it has a way bigger capacity:

The saw jig looks like a quick way to sever limbs - be they of the wood or flesh variety.
Ingenious mechanism, but anything that separates the operator from direct control of the saw, as this does, makes me a little anxious.
Same reaction I have to all the recent investment in "driverless cars" by big companies with more money than sense.
That Mottimaster, on the other hand, looks very cool.

I like the idea, but can't see it any good for big wood. The mottimaster is amazing! I want one...

when you push it hard in heavy oak, a ground drive PTO (to reverse it through the tractor transmission) is a MUST !!
And despite shearbolts i've ripped PTO tubes open over the full length, powering it. Its human nature to push the machine to its dimensional limits (poking whole trees in the hole so the tree has nowhere to split and the axe jams stuck in the tree) because its so much faster than sawing and splitting...

This is an older model of the original manufacturer (Mottimaster is a licensee)

If you pull it to 1800rpm and put 8 inch tree in it at every time the hole is open, you're dead within minutes... But if you could physically keep it up, you get 3 cords an hour, cut and split... We operate it with 2 people, one limb after the other so you can take a breath before the next limb..

There was a post here a while back that had a few machines that cut short lengths like this and were self feeding. Used blades that counter rotated from one another and both sets met edge to edge that severed the wood into sections. As soon as you stuck the end in the machine you would go to pick up another while it chopped it into sections.

The idea originates from central europe, mostly Poland and Czechia. We intend to build one next winter, use tractor final drive bull gears to drive the rotors, and put a drum sieve behind it to remove leafs and shreds from the firewood, so we can just push any limb into the machine, and separate the firewood from the trash with the trommel instead of by chainsaw and by hand. Then my mottimaster will be for sale, and someone with a stronger back than me, may feed it


This is a commercially available model from Czechia, its more like what i have in mind. (wood must be small enough to dry but when you make it smaller than needed, its going to cost you capacity and fuel. the energy must go in the stove, not into the tractor that drives the wood machine)

Geart machines andit was really very eye opening to see a really efficient way to cut up and split wood!!

With all respect, what are those little short pieces of wood used for?

Exactly my thought, on both of your remarks

Short pieces are most probably for automated heaters so the auger doesnt jam. I want longer pieces of about a foot long, to feed my workshop heater. OR i'll feed it with an old fashioned coal shovel because the chunks are about the same size. Maybe its even easier to just shovel...

Thanks, I thought they must be for some sort of automative feeder, but have never seen anything that would work with that size pieces.

It's too bad that lawyers and insurance companies basically run our country so we don't have any chance of seeing those sold here commercially....

Maybe when I get better at welding I'll see if I can figure something out.

Heck, I'd even settle for the weighted splitting head with spring assist rather than sit or stand at a noisy hydraulic gas engine driven splitter.

I have looked at a few branch loggers on line and I like the TR 70 I wish they would sell them here. My thought is that if you could use a burnable bag, you could stick the whole bag into a wood boiler. It would also eliminate waste of the branches.
