A new harvester from Rottne

Rottne is having its world premiere at Elmia Wood for a totally new harvester. The H8D harvester has an innovative and newly developed powertrain resulting in lower fuel consumption and considerably less ground damage.

The machine contains many innovations. The most important is a totally redesigned powertrain with an engine that meets the latest Tier 4 emissions regulations. Instead of a conventional hydrostatic drive with a gearbox, the powertrain has a hydraulic motor in every wheel hub, combined with traction control. The solution is similar to what the aviation industry calls fly-by-wire. A computer ensures that every wheel supplies the optimal power without skidding.

“We’ve presented it to the dealers and we already have nine to ten orders from customers who haven’t even seen it,” says Tobias Johansson, CEO of Rottne. “The trial results show lower fuel consumption and a significant reduction in ground damage,” Johansson says.
Like its predecessor the H8D also has swing arms. Together with the new transmission, the result is exceptionally good accessibility.

Forest owners, not least small-scale ones, are demanding smaller harvesters due to the issue of ground damage. The disadvantage is that they must work longer to achieve the same capacity as a traditional harvester. With its new H8D, Rottne has found a compromise that should appeal to forest owners. This harvester will have its world premiere at Elmia Wood on 7 to 10 June.
