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.

ELECTRICITY FREE CONTROL

Naarva K24 felling head is mounted to a loading crane to the place of a loading grapple. All functions are operated with "grapple open / close" valve. It does not require extra hydraulics or any electricity.

Sequence valves operate cutting and tilt function automatically. When "grapple close" function is used and pressure reaches a limit, the guillotine starts cutting. When "grapple close" function is kept pressed the pressure reaches a higher limit and the felling head goes to loading position

QUICK AND STRONG GUILLOTINE CUTTING

New quick and strong cutting guillotine was designed for Naarva K24. It can cut up to
24 cm (9" ) thick trees. Cutting time is 1,2 seconds (oil flow 70 liter / min). Guillotine grips close around the tree and press it against the cutting blade.

The cutting guillotine is maintenance free. Only maintenance required is greasing the nipples. Cutting unit is on a sliding frame so strain from the cutting does not damage the felling head.

LOADING OF TREES

New Naarva K24 felling head is very suitable for loading of trees. Hydraulic cylinder tilts the head to loading position. You can load and cut trees in the loading position. Cutting blade is in the back and is not in the way when loading.
