Cheers for this guys, really appreciate getting some good advice, to go on a valtra 6800 115 Hp with a roof mount on so a bit of extra weight. Used to just set up some snatch blocks and pull over with a  tractor or digger but a bit of a pain finding runs on tighter sites

Once you are in the realms of a single rope pull of a leaning tree with a tractor winch the art is in judging just how high to mount the rope. You want the winch to give the tree sufficient impetus such that the risk of the hinge cracking out sideways is overcome. The hinge only directs for the first 10 degrees of movement then gravity and momentum take over. Put the rope too high and the winch never keeps up with the initial movement and goes slack before the tree has speed in the right direction.

 

 

 

 

This is great stuff, I sort of knew this, but seeing it explained coherently is invaluable.

Easiest way to remember is to get it wrong once next to a greenhouse. You won’t forget next time. 
 

Not me, another tree team. I was just there scrounging some oak butts for the mill.

Quite a few years ago I got a sawmill in to take 4 big firs out from a garden.

They sent a tiny bloke out (powerfully built mind) with a double drum winch articulated skidder

He would back up to the trees stand on the winches and wrap the cable at maybe 15 ft up these 90/100 ft trees. I asked him if he wanted me to set it higher but he said no (we know why now of course)

Then he’d drive the skidder away and using his remote on his belt tension the line, this massive tree shook like the Hulk was pushing it.

Then he’d fell them with a 066 with a short bar, always a keyhole cut followed by a walk around, a turn of the button on his belt, and the tree went over good as gold, and as Openspaceman explained tension on the cable was held much longer into the lay.

Bloke was a bloody artist.
