Nisula Harvester Head 425 H

Nisula 425H is a thinning harvester head equipped with additional knives. The harvester head processes the stem in a controlled manner. A new type of head control improves the speed and precision of the process.


The new stronger drive motors increase the feeding capacity by 20% compared with the previous model. The new machined front knives provide improved delimbing efficiency and durability. The additional knives of the new 425H head increase productivity with even larger stems, 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.
