500H is a powerful alternative for the subsequent thinning and final cutting of small stems.

Its physical dimensions are suitable for thinning and, thanks to high quality materials, the weight is also contained, only 640 kg. 500H is a harvesting head equipped with additional knives that make it easy to handle even large stems. The additional knives increase productivity with even larger shanks, something that harvesting heads in the same weight class are unable to achieve.

The NCU3 control system adjusts the gripping force of the head according to the size of the stem to be manipulated. When larger trees are felled and heavier stems are handled, the grapple arms along with the front and rear knives and roll cylinder apply stronger gripping force to the stem.

When feeding begins, the gripping force is gradually reduced to minimize friction. The control system has a diameter limit set to reduce the gripping force. If necessary, the settings can be adjusted via the control system, but usually the harvester head works best with the standard settings.
