An economic stroke harvester

The Naarva stroke harvester is a reliable and efficient tool for forest owners and small contractors. It is designed for use in first thinning, production of firewood timber, and energy wood harvesting. Delimbing facilitates integrated harvesting also. With a stroke harvester, the first thinning is completed productively and without damaging the forest. The head is only 80 cm wide in the felling position, which makes it easy to operate in young forests. Radio control also allows for the free rotation of the grapple, which contributed to the ease of working in tight and narrow places such as first-thinning forests.

An effortless and durable guillotine solution

A patented guillotine with a 25 cm cutting diameter is used for cutting. When cutting, grippers close around the tree and an 8 mm blade made of wear-resistant steel cuts through the tree. The cutting surface is smooth and even because the trees are always cut against the grippers. The guillotine slides along a sliding bar and puts no strain on the other structures of the stroke harvester regardless of the thickness of the cut trees.

The blade is not easily damaged or lose its sharpness, which means that the trees can be cut very close to the ground. Low stumps do not damage the tyres of the tractor and no valuable wood is left in the forest. The maintenance of Naarva stroke harvesters mainly consists of greasing the joints.
