More properties to enhance harvesting operations
Nisula 425C is a multi-purpose harvester head equipped with grapple arms that make timber handling and sorting effortless. The NCU3 control system adjusts the grip force of the grapple arms to the tree stem, enabling a firm grip during felling, feeding and other operations. In combi-machine use, the separate grapple arms also allow loading without changing the head.
When larger trees are felled and heavier stems handled, the grapple arms apply a strong grip to the stem. When feeding starts, the grip force is reduced to minimise friction. The control system has a diameter limit set for the utilisation of the grapple arms during harvesting operations. If necessary, the settings can be adjusted via the control system, but usually the harvester head works best with the standard settings.
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 as well as a larger delimbing diameter compared with the previous C-model. 425C offers additional properties for thinning.Get Brochure
