ROTTNE H8

A SMALL HARVESTER WITH HUGE POTENTIAL

Several evaluation studies have shown that stand-operating harvesters produce the most consistent results during mechanical thinning. Rottne H-8 has all the qualities required to ensure successful thinning using secondary roads in the stand. The pendulum arm system means that the machine width is always maintained, even when the ground is uneven or you encounter an obstacle. The operator sits in a cab offering superb all-round visibility, while hydrostatic operation and precise tracking make this small yet flexible harvester even more versatile and easy to move forwards or backwards with great precision. It is easier to select the right tree when the operator is never more than 6-7 metres from the trees to be felled and the risk of damage to standing forest is also reduced considerably more than if thinning were to be performed from a strip road 10-12 metres away. When the harvester is equipped with a system for GPS/GIS, the forwarder operator can access tract maps with working routes and timber volumes per strip road to ensure that everything is being collected. The landowner can also access detailed information about thinning for his forest management plan.
