Re: Settin\' a pull line HIGH in a Conifer...
The treepedo helps with installing in conifers. I'll settle for one throw close to the stem and walk the rope around and do a double rope pull. Like they said previous you still gotta climb if you need a solid connection like a side rope or backleaner.

Re: Settin\' a pull line HIGH in a Conifer...
Hey all, I was lucky and we had a split stem at about 95ft. I was able to get a shot through second try with the big shot and trunk tie no problem, nice and tight and nice and flush with the trunk. We only had a few feet of back lean and wind in our favor so it was easy-peasy. After 3/4 of my back cut and only one round of tension on the pull rope (was using a Maasdam continous rope puller)my wedges went loose. I cut a hair more, and walked away on my retreat path a bit and then turned to watch the show. I dismantle so many trees piece by piece that it's still so impressive to see a big one fall. I could have done it without a pull rope due to all of the favorable conditions but always better safe then sorry right?

"RH Pusher" works good
I used one in Sweden, but not cheap!

It works, but it ain't no replacement for a pull rope on most big trees.

Re: Settin\' a pull line HIGH in a Conifer...
I noticed that using the 'High Ball' works well. It's a golfball shaped throw bag that bounces around nicely, it also fly's through the air like a dream... Now if I could only teach myself how to hook and slice the thing we would be in business. Or... I may just be partial to it because I've golfed my whole life.

Is there any loss of leverage by going up and over to a trunk tie vs. setting the line only in the top?
[/ QUOTE ]
yes, the leverage is better when the rope is tied directly to the top.
pic 1 - top tie
pic 2 - trunk tie off
Basically - You need to apply more force to pull the tree over using the trunk tie off method.

Nope, same force.
Running the rope over a limb and then tying lower on the trunk does create a compression force on the trunk which when combined with the force applied to the hypotenuse of the triangle does result in a resulting force like Grover pictured.......but it does not diminish the force applied in the line of the hypotenuse. If the trunk were to be weak though it may increase the possible of a trunk collapsing.
I think the rotational force generated and mentioned by Jomoco is usually neglectable.

I was thinking the same. The lateral force for pulling over the tree is the same. The compressional force on the stem is higher, at the same time, with the base of the trunk tie.

Re: Settin\' a pull line HIGH in a Conifer...
I agree a certain fixed force is required to tip the tree past the centre of gravity.
But with the trunk tie off method your not only pulling the weight of the tree, your also fighting against the downward force which you have created by using the trunk tie off. Look at the second picture again.

Re: Settin\' a pull line HIGH in a Conifer...
eather way you look at it, you are lossing pulling force by doing a base trunk tie off. also you can stand the chance in some cases of losing the direction of pull while you need it.

Re: Settin\' a pull line HIGH in a Conifer...
I'd like to try a miniature scale high speed reel feed drop test with a good video camera.
It would be an accurate representation of a large scale precision felling challenge
Like say a long corridor alley, with a bowed dead stick, leaning way off center?
Who could lay it out horizontally in seconds and stretch it out on the rack like a medieval torturer stretching his victim using rotary springs and whatnot?
