Tree Shear

[J_J]

Maybe something like that might work. Use it to take bites out of the tree
until you get to the bottom.

If your roll over assembly is strong enough, it should be able to cut 3 or 4 in limbs.

If you make the whole assembly a plug in to the end of the boom, you can mount it in any position, even upside down. My whole unit is about 30 in long including cylinder. If I wanted to reach out further, I could add an extension.

I can't easily see it, because the minihoe cylinder operates front-to-back, while a tree shear would need the cylinder operating side-to-side, wo move the blade. If you could adapt one, I think it would be more readily made to operate vertically (cutting limbs) versus horizontal (cutting trees).

Kent,

What if you mounted a bracket on the side of the mini hoe that is equal to the one on there now. Then, you could mount the cylinder on the side, and push the shear in a horizontal plane. You could then switch back and forth to get the job done.

You could certainly do that, by unbolting the cylinder and moving it to the side. Not exactly a "quick attach" kind of change, though...

Personally, if I were going to try to make a relatively inexpensive one, I think I'd try to fab one up to fit the 2" receiver mount. Then you could rotate it 90 degrees to go from vertical to horizontal, and vice versa. IMO, you could put a fairly long boom on it, perhaps even one that extends (using a sleeve and set screws), because all the boom has to do is hold up the weight of the shear. You wouldn't be using it to lift anything...

You can buy a double-action tie-rod cylinder fairly inexpensively...

I have built what you are talking about, and it works quite well.

Are there any plans out there to build a mini-hoe similar to the power-trac?
It doesn't appear to be too involved, but if I were going to build one, I would rather duplicate something that has been proven to work.

Bob, My Turbocad program has vanished, so here is a basic drawing .

When looking at drawing, press the ALT key and use the mouse wheel to expand.

J_J, Thanks for the sketch. Looks doable. Would it be better to have the moving piece be an arch, so it does not push the branch out when it cuts? Of course it would have to mate with the anvil (non moving part). Or is this just overkill?

Hey guys,

I am new to the forums, been reading awhile. I posted some on the hydraulics pages because I wanted to build a tree shear. I dont know how I missed this post. I am still trying to figure this out. If anyone has plans or pictures of a homemade tree shear it would be greatly appreciated.

Thanks

How about something along the lines of this - Its called a stump splitter

Just curious if you ever finished your shear? I have a bobcat 335 mini-excavator 8500lbs. I am in the tree business and firewood business. I have seen shears on 40k-80k lb machines and have been trying to downsize the idea to my machine. I want to use it for busting/splitting smalller diameter logs and chunks of firewood. Any thoughts?

Are you talking shear or splitter. Two different things, A shear will cut the tree down, and the splitter will split it up in smaller parts.
