okay is there any tree surgens on this board

My father is building a extension to a garage and there is a small tree about 1ft in diameter that is just going to get in the way instead of chopping tree down is there anyway of bending it over.

We have a 5 ton winch and a chain saw Can we cut half way through the tree without killing it ?
