The new Nisula 555C is a multi-purpose harvester head equipped with grapple arms that make timber handling and sorting effortless. In combi-machine use, the separate grapple arms also allow loading without changing the head. The manufacturing quality and materials of the head are of the standard that Nisula is known for. Considering its properties, the head is exceptionally light, only 810-840 kg, depending on the equipment.
The Nisula 555C offers numerous new properties: completely new hydraulics for heavy flows, efficient Nisula NSU saw assembly, bolt-mounted saw casing equipped with a blade lubrication tank and patented Nisula Goldfinger guillotine cutting function. This harvester head has properties that improve cost efficiency.
The NCU3 control system adjusts the grip force of the head to the size of the stem being handled. 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 reducing the grip force. The grip force of the grapple arms is controlled proportionally. If necessary, the settings can be adjusted via the control system, but usually the harvester head works best with the standard settings.
