I was just wondering, for the height you cut them at ... you might as well have cut them at the base? Yes/no
On the 1st one, it looked kinda wierd like where/what was your attachment ... a flip line, highline etc??? Just the way you leaned back to avoid the noggin.
Did you know the butt was gonna swing off like that?
Hmmm, I do snap cuts, or mismatch cuts, get out the way then the crane can have it ... I personally dont like the idea of being in there with a saw running when it goes.
You cut the side of the crane first then the safe side last, over lapping the cuts, the crane has some vertical lift on ... usually enough to hold the peice stable, you clear away and then the crane lifts and/or slews towards itself to snap the cut. You only mismatch them by 1" or so depending on the timber of course.
But hey, whatever you're used to and the driver too I suppose, trouble is you always getting different drivers and if you get one that hasn't done trees before that sucks!

nice work! i know it is difficult to get those picks to balance out.(if you tie too high the thing might break, too low...the thing wants to flip!) but i agree with ekka, watch out for headhunting limbs! it looks like you have many years experience. good job.

Cutting at base would made it almost impossible to put the tree down at the narrow place we had. The crane could lift it. Also they put in a brand new fence with poles about one feet from the trunk. So i also cut them higher to avoid the trunk to hit the poles. We removed the fence between the poles to be sure of no damage.

I use a flipline and my rope around the trunk or over one of the lower branches.

They usually do the way i rig i quess. I think most of the uneven crown and weight settling the butt swings. So i do expect that to happen and be prepared.

I just look what way the top will go, cut straight trough. Its a reflex to put the chain brake on and duck. The saw isnt on a cord and i have no problem to ditch it when needed. (never did though) I rarely make snap cuts or mismatch as operators have a hard time to get them braking with reasonable force.

I met only one or two operators to perform this way of cutting the tops/limbs out. The rest rarely do trees.

Snap snap, hahaha
All's good, take care, different strokes for different folks they say.
Couldn't see the fence and stuff in the vid ... and yeah, nice clean up crew.
A guy I know cut a long log/block off and the "noob" crane driver didn't lift it or do anything ... just let it swing around and it slammed into the trunk just missing the climber and crushing his ropes ... close call, poor bugger had nowhere to hide and the driver did that!

Look again and tell me
I know i have to take better care in safety....

Ok i say it.
I cut the limb with both climbing lines parallel to eachother. I forgot ( /forum/images/graemlins/9lame.gif) to connect my lanyard. So that made a hazardous situation when if my saw kicked back and could cut both lines beeing so close to eachother. This situation would made you fail a arborist test.
Beautiful eyeopener pics of youre own work setup.
