Sampo Rosenlew - Model HR46 - Forest Harvesters
The HR46 is the new workhorse for first thinning. Even more powerful than its predecessor 1046pro, the harvester now has a larger, 135cc pump, which facilitates operation at an engine speed reduced by a third. This change improves performance and reduces consumption, which translates to increased profitability of thinning operations for the owner.
Power transmission is now fully hydrostatic to allow for rapid movement from tree to tree without increased engine speed. Gear changes in the multi-speed motors are electronic and, as an option, automatic. The automation drive technology also offers a driving mode which finishes with maximum diesel speed, automatically enabling maximum transmission speed.
As the cab of Sampo-Rosenlew harvesters has always been located in a separate frame away from the motor, users of Sampo-Rosenlew harvesters are accustomed to a comfortable and quiet work environment. Add to this the changes described above, reduced engine speed, the gearstick's removal from the cab, as well as a number of other modifications in this model, and the result is an incredibly quiet cab.
The Sampo-Rosenlew HR46 harvester goes into zero series production in spring 2013 and serial production in autumn to coincide with the discontinuation of its predecessor, the 1046pro.
