[0002] Felling, also known as forest felling, is one of the basic processes in timber production. It is the operation of felling trees according to the purpose and requirements of forestry management, including tending felling before trees mature and main felling of mature and over-mature forests. Felling is a management activity for forests and trees, including main felling, tending felling, renewal felling, and low-yield (efficiency) forest transformation felling. The main felling includes three methods: clear felling, selective felling, and gradual felling. In the process of mining, in addition to transferring the main trunks of trees with thicker diameters, a large amount of residues such as branches and leaves will remain. In order to better handle this kind of residue, the residue is generally crushed on the spot and then transferred through subsequent loading.
