<p>The object of the invention is a method and an apparatus for cutting a tree. In the method a delimbing & crosscut device (1) cutting branches and able to cut the trunk of a tree is controlled upwards along the trunk of a tree intended to be removed and when it ascends to cut the branches of the tree that are in its way. The delimbing & crosscut device (1) is controlled to ascend and descend along the trunk of the tree step-by-step by alternately increasing and shortening the length of the delimbing & crosscut device (1). In connection with the removal of a tree that is in an inclined position, such as a tree that has fallen onto an electric line, a pulling rope (7) is fixed to the delimbing & crosscut device (1) for pulling said rope up into the tree, by means of which pulling rope (7) the tree is pulled upright or off the electric line.</p> |
