Stump removal with my Komatsu_1997 PC75UU2

Thanks, Bart I am finding a commercial machine is real a kick to operate. I bet that Case Super M is a blast to work with to.

crazyal I see what you mean about pushing trees over

I made a deal with the wife- since we needed to warm up the engine before the oil change.

She could learn to drive it and pop out a stump or push over a tree.
This one lost a top during a violent storm last year.

I think she did very well.

Oils changed and took out 3 more trees and grappled them out with the Rhino for fire wood-
the stumps and dirt are my only real problem now?!..(getting them out of the ground) was only part of the job.

But we are having fun.

Stump removal with my Komatsu_1997 PC75UU2

It is a small Excavator, 18,000 Lbs, really only about as strong as a commercial backhoe.

This is my technique for surgical removal of trees. It works with hardwoods 6" to 8" diameter and birch and pine to 10" diameter or a bit larger.

1. Decide which way I want tree to fall.
2. Dig to break roots right next to trunk 220 degrees around the tree OPPISITE the side that you will fall the tree.
3. Get bucket under the root ball and lift. The roots still in the ground will make the tree tilt in the direction you wanted it to fall.
4. As I have now loosened the tree, and it is leaning a bit, I grab it with the thumb and rip it out.
5. Watch out swinging the tree, it is like a 30 to 40 foot baseball bat.
6. Move tree to where you want to cut it, buck it and cut up for firewood holding tree off ground at a comfortable working position.
7. Take a break.
8. Repeat.
A large excavator (+30T) with a thumb could log really well and handle large trees, but few larger machines have thumbs, plus bad things could happen quick.

For large trees. I wrap a strong chain as high as I can reach with a 24 ladder then cut them and pull them with a 100 foot cable. When the tree starts to go, I swing the boom to pull fast as I知 backing up. I have had the tops of the tree brush the cab. A good scare, but the branches are small at the top. Around here, 90 to 100 Ft tall is a big tree. 99.99% of old growth has been cut.

Thanks for the info Mike,

I am going to use the rippers on any of the stubborn trees roots - but so far i have only come up against 1 stubborn enough stump to require the rippers yet.

We actually rented a 312 Cat excavator when we were first clearing the land and we dug a 17 foot hole and buried the original stumps from the trees that were pushed over.
Then had use of my sisters bobcat ( Komatsu) mini ex
simila,r but older design than yours for quite a while- Those are great units. We used it to dig power line ,water lines and bury them. Also
The semi pulling in half of our new modular home (26 x52) got stuck in the mud... and It was pouring.
i was able to hook a chain on to the semi tractor and literally drug him AND the house into position on the slab. I am still impressed with that PC 75 ? machines performance.

As for the stumps that are being removed now,
We still have the fairly large burn pit that we dug with the 312 - but my understanding is that we are not allowed to burn the stumps for 3 years from the trees demise.
So for the moment we are taking the trees out with the 550g and then i cut the root ball off and then pick it up and drop it a few times with the grapple
( to remove some dirt) with my rhino tractor and then grapple them over to a pile to sit and hopefully loosen the dirt - so by 2018 Hopefully - into the burn pit they will go.
At least that is the plan for now.

Thanks again for the info -and enjoy that Komatsu

That's awesome!

thanks she is wanting to get rid of a bunch of small diameter trees from her horses field so we are going to take turns doing some of this tree/stump removal.

And the best part is -we should have lots of new fire wood.:thumbsup:
