A Harvester head is a machine used to cut down and harvest trees. The working principle of a harvester head is to move the blade or chain saw along the tree in an inclined or horizontal direction through a mechanical or hydraulic system to cut the trunk. The hydraulic system provides power with better control and precision, cutting and cutting trees into appropriate sizes in a fast and efficient manner, and can operate at different heights and positions. It provides convenience for forestry, construction, wood industry and other fields. When using a feller, be sure to pay attention to safety matters and follow the operating procedures to improve work efficiency while ensuring your own safety.
