The handpiece of the mechanical tree dozer is advised to fixed on the excavator with the weight 15-25 tons, and the Maximum diameter of tree cutting is 50cm. Mechanical tree dozer is also called forest harvesting combine(cutting and felling combination machine), and divided into the wheel type and apron wheel type, have been come out over 30 years in the North Europe and North America. Mechanical tree dozer is a kind of tree felling machinery using for cutting and felling, removing branches, debarking, transecting the tree stem. A large type mechanical tree dozer can fell 100-140 trees with the diameter of 50-60cm per hour, is a dozen times of the artificial felling. SP 561 LF is a kind of all-round felling handpiece with high performance, and designed to reduce friction and improve efficiency. The LF design is particularly thinking about the different requirements in different stages, ensuring the distinctive work efficiency from the  first intermediate cuttings to midway intermediate cuttings, and to the final overall process of the felling tree.
The delicate appearance, combined with the perfect branch-removing system which can reach the depth of 30mm, ensuring that the first intermediate cuttings can be finished quickly with high quality. In the final felling, namely when dealing with the tree stem with large diameter, SP have  the flexible tree stem fixing system, and ratio angular orientation feed wheel, making the SP 561 LF to fell and process the trees with surprising ability and the weight ratio, and unparalleled efficiency. Benefiting from the design tenet of low friction force, this type of the machine can also deal with the trees with the larger diameter efficiently. Also in order to make the equipment exert the Maximum efficiency under the different circumstances. The SP 561 LF is equipped with many kinds of flexible patent system, such as tree stem clamping system, ratio angular orientation feeding system, independent knife control system. etc
