Felling Heads

We are a representative of the well-known Finnish harvester aggregates and the Naarva grapples.

Naarvas high quality Finnish harvesting units and trap heads are manufactured by Pentin Paja AB, a family run and owned company. Since the very beginning in 1982 Pentin Paja has concentrated on the development and production of forest tillage machines.

The products can be mounted on everything from smaller agricultural tractors up to major forestry machines. Its fully integrated hydraulic uses the same hoses as the load grapple. The only extra equipment needed is a power cable between the cab and the grapple. Read more about the products at www.pentinpaja.fi

 

Naarva K models are reliable combinations of a felling head and a loading grapple. They are suitable for all kinds of clearing and thinning operations. Naarva felling head is quick to install in the place of the crane’s own loading grapple or harvester head without additional hydraulics or hoses.
