Alternative solutions.
• Turn the tree down to the side
• Prize the butt end backwards using the step down method
• Bringing down with winch, tractor or other machine
Turning the tree down to the side is a quick and easy method that works well when the hang-up is not too complex. A straight trunk indicates
that the tree can be rotated while a curved trunk indicates the contrary. If the tree is heavily hung up with another tree, it is futile to try to turn
it down. If prizing the butt end backwards does not help, all you can do is call for the aid of a tractor or harvester.
Note: Never leave a trapped tree unmarked. Mark the area with highly visible marking tape if you must leave the area to get other tools or
assistance.
Turning down method.
Use a turning strap or breaking bar with turning hook if you think that the tree is not too trapped.
To remove a hung tree.
If you accidentally fell a tree into another – always start by taking a break and thinking through the situation calmly. Removing a trapped tree is
always a hazardous undertaking and there is no need to rush. Choose the safest solution to the problem even if it takes longer. There are several
options. Do not be afraid to call for help – your safety is more important than anything else.

Follow these steps:
1.Assess which way the tree can be rolled down. Saw off the middle of the hinge so that two corners are saved. Next cut off one corner with
repeated saw cuts diagonally from above. Leave the corner on the side that you intend to roll down the tree.
2.Take the turning hook (turning strap) and roll the tree away from you. Lift straight with a straight back and knees bent. If the tree is large or
has hung really tightly, you can increase the rolling force by using the turning hook or turning strap with a longer piece from a thin tree.
Warning: never turn the tree towards you!
