NUMBER ONE IN LIGHT HARVESTER HEADS Nisula 325H is a harvester head that is especially suitable for first thinning and delimbed energy wood processing. It is light and easy to use, making work fast and effortless. The head is equipped with one fixed and three moving delimbing knives. The spring-loaded blades of the basic model automatically follow the contours of the tree stem during delimbing. With normal stem forms, this is the easiest-to-use solution for the operator, as well. If the conditions require, the front knives can be equipped with cylinders. The cylinders allow the opening of...

USES • First thinning • Delimbed energy wood processing SUITABLE BASE MACHINES • Light harvesters • Farm tractors equipped with an adapter sleeve mounted crane • Light forwarders with head change facility • Lighter than 8-ton excavators

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. A 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 knives of the new Nisula 425H also increase productivity, something that harvester heads in the same weight category are not able to achieve. The...

NISULA 425CMORE PROPERTIES TO ENHANCE HARVESTING OPERATIONS Nisula 425C is a multi-purpose harvester head equipped with grapple arms that make the processing and sorting of timber effortless. The NCU3 control system adjusts the grip force to the size of the stem being processed, enabling a firm grip during felling, feeding and processing operations. In Combi-machine use, the separate grapple arms also allow loading without changing the head. When larger trees are felled and heavier stems processed, the grapple arms apply a strong grip force to the stem. When feeding starts, the grip force...
