Sampo Rosenlew forest harvesting machines

Sampo Rosenlew’s specialist thinning harvesters do the thinning job excellently. Thinning is important for sustainable forest management. An early thinning is undertaken to properly space and grow the stands for quality and to improve forest health. Thinning harvesting is difficult and costly because the remaining trees must not be damaged and the yield per hectare is small. Logging cost control is the key to profitability. Sampo Rosenlew forest machines are designed with a view to cost-effective thinning. Appropriate size for thinning operations, durability and a well-thought-out construction result in capital and running costs clearly lower than those of the competitors. 

Sampo Rosenlew began the serial production of forest harvesters in 1997. The first harvester designed specifically for the first thinning was the SR1046. … Read more about  Sampo Rosenlew forest machines

The HR46X harvester is the number one choice for profitable first thinning. It is small and light enough to have a low impact on the environment, yet it has ample power to get the thinning done excellently. The HR46X is equipped with a 140cc pump and a powerful Agco Power 49 AWF engine. The harvester is very fuel efficient. An operating mode can be selected from the operation automation menu, which increases the diesel engine RPM to maximum, thus allowing for maximum transmission speed. The HR46X does not damage standing trees or scar the ground.

forwarder FR28 for profitable thinning


In 2015, the FR28 forwarder was added to the Sampo Rosenlew’s product family. The FR28 was designed to couple with the Sampo Rosenlew thinning harvester. This 10-ton load bearing forwarder with a high steering angle is so small it can move easily and skilfully among the trees and move the harvested timber out of the dense thinning forest. The FR28 is very light on the ground.

The HR48 has been designed in response to customer demand for a larger yet light forwarder with an increased load capacity and more wheel capacity to lower the ground pressure. The FR48 is suitable for bigger logging sites and for hauling logs from late thinning or final felling operations. The FR48 will be a good companion for Sampo Rosenlew FR86 harvester and  for other medium-sized and large forest harvesting machines.
