Sampo-Rosenlew - Model HR46 - Harvester
From Forest Machines
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.

Product Details
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.
Why Sampo Rosenlew?
THINNING HARVESTING, GENERAL FACTS
When forest is managed, the goal is usually to maximize the production of wood, in terms of quantity and quality. This is also the aim of all the harvesting activities which fall into two categories:
- Harvesting for growth which includes thinning.
- Final harvesting where the aim is to create a new generation of trees to replace the old ones.
The purpose of thinning is to concentrate the production capacity of the forest soil - and wood growth - on certain individual trees.The goal is to produce big trees with good technical quality. The entire space should grow a dense, even and healthy forest.
The machines should be technically suitable, keeping in mind the aim in each harvesting operation. Consequently, in thinning when a densely growing forest must be left undamaged, the machines should be relatively small, maneuverable and suitable to operate in sections of forest without harming the remaining trees.The area used for strip roads where the machinery moves has to be minimized since as much space as possible should be left for the trees to grow.
The above mentioned facts result in the conclusion that the Sampo Rosenlew machinery is a superior alternative to be used in thinning operations.
ECONOMY IN THINNING OPERATIONS
In thinning, like in every phase of wood production, the costs should be minimized. However, this must not weaken the effect of these operations i.e. their efficiency and quality.
The cost of mechanized harvesting can be roughly divided in three groups.
- The capital cost that depends on the purchase price of the equipment.
- Personnel costs consisting of wages with their side costs.
- Other running costs such as fuel and lubricants for the machines as well as service, transport, insurances and other miscellaneous costs.
The capital cost can be affected by choosing the most inexpensive alternative of the functioning machines available. Little can be done about the personnel costs with technical solutions. Other running costs can be reduced by choosing the most economical alternative of what is available.
Since the Sampo Rosenlew thinning harvesters have proved to be reliable, extremely price competitive and fuel efficient, they are the best solution to thinning.
