NAARVA S25 TELESCOPIC HARVESTER HEADS

Tractor and Excavator 5 - 9 Tn

  • Patented guillotine with a cutting diameter of 25 cm. The sash is durable and easy to maintain, even in difficult conditions.

  • Low stumps do not damage tractor tires and no valuable wood is left in the forest. Maintenance of the harvester head mainly consists of greasing the joints.

REASONABLY PRICE HARVESTER HEAD FOR TRACTOR CRANE

Naarva harvester heads are reliable and efficient for initial thinning. They have been specially designed for cranes used on agricultural tractors and small excavators. The lightweight Naarva S25 model is a traditional harvester head. Naarva S25 operates with an oil flow of 40 l/min, and no additional hydraulics are required when installing on a tractor or excavator.

DURABLE AND EASY TO MAINTAIN GUILLOTINE SOLUTION

Cutting is done using a patented 25 cm diameter guillotine, which is durable and easy to maintain, even in difficult conditions. The retaining arms wrap around the wood when cutting and the 8mm wear steel blade penetrates completely into the wood.

The cutting surface is smooth and even, because the cut is always made against the holding arms. The guillotine blade slides along the sliding bar and puts no pressure on the other structures of the harvester head, regardless of the thickness of the trees being cut. The blade is not easily damaged and does not lose sharpness quickly. This way, the tree can be cut down to ground level. This means that low stumps do not damage the tractor tires and no valuable wood is left in the forest.
