Forest thinning felling head 425H

with delimber

Ideal weight/efficiency ratio for thinning Nisula 425H is a thinning harvester head equipped with additional knives. The harvester head processes the stem in a controlled manner. The new type of head control improves the speed and accuracy of the process. New stronger driver motors increase the feeding capacity by 20% compared with the previous model. New machined front knives offer improved delimbing efficiency and durability The additional delimbing knives of the new 425H head increase productivity even with larger trees, something that harvester heads in the same weight category are not able to achieve. The additional knives also allow a larger delimbing diameter. The head is a most suitable choice for thinning.
