Sampo Rosenlew Ltd
Sampo Rosenlew Ltd has a long tradition of the manufacture of farm and forest machinery.
Wheel-mounted machinery has been manufactured since 1957. The company is well known
for its high-quality, cost-efficient products. Serial production of forest harvesters started in
1997. Harvester design was started from scratch. From the very beginning the Sampo Rosenlew
harvester was designed to be ideally suited for forest thinning.
Most of the components used in the base machine are manufactured by Sampo Rosenlew. The
hydraulic motors and rotors are supplied by Sampo Hydraulics Ltd.

Unobstructed Visibility
from the from the Cab! Cab!
Enjoy the comfort! Sitting in the cab of the Sampo Rosenlew forest harvester
makes the operator feel like the king of the forest. The cab is placed on the
front frame, far from the hydraulic pumps and the engine. The curved windscreen
and the high cab provide unhindered all-round visibility round the machine and
over the trees. The controls are ergonomically within easy reach of the operator.
“The curved windscreen and the high cab
provide unobstructed visibility.”
Good View over the Trees
The large window area guarantees unobstructed visibility round the
harvester and over the treetops. This enables efficient working and
selection of the right trees. In forest thinning unhindered visibility is of
the utmost importance.
The pre-heating system and solar curtains will further improve operator
comfort. Improved driver comfort results in increased work efficiency
and reduced fuel consumption.

Unrivalled Mobility
on Rough Terrain Terrain
Rough on
A forest thinning machine works in young and dense forests. The most essential aspect in the design
of the Sampo Rosenlew forest harvester was its suitability for thinning. The four-wheeled harvester
with articulated steering is extremely nimble. The joint, short wheelbase and wide steering angle
enable an amazingly small turning radius and provide excellent agility. Efficient hydraulic traction
motors and a self-supporting joint ensure unrivalled mobility over most demanding terrain.
Gentle-touch Forestry
The small dimensions of the SR 1046 pro guarantee that the harvester is agile and
eco-friendly and thus well suited for first thinning of forests. A lightweight harvester
does not harm the roots of the remaining stand of forest as heavy harvesters do.
The measurements such as the weight and track width of the harvester are large
enough to ensure stability of the base machine in forest thinning. The large contact
surface of the tires reduces the load on the ground. It is essential for forest productivity
that the remaining stand of forest stays healthy and undamaged.
Flexible Forest Harvesting
Crane handling on the Sampo Rosenlew harvester is superb in thinning forests. The
side-tilting crane can reach trees further away than a fixed crane. The side tilt can
be equipped with an automatic side tilt stabilizer system.

Engine
The SR 1046 pro forest harvester has a four-cylinder Agco Sisu Power
44 CTA diesel engine with the Common Rail joint pressure injection
system. The engines meet the latest emission control requirements.
The engine torque is highest at regular working revolutions. The
engine´s fuel efficiency is unrivalled. Long service intervals and easy
serviceability increase efficiency. The engine is quiet and vibration
free. Diesel idling as well as working and maximum revolutions are
quick to select using the rocker switch.
Transmission
The pump in traction hydraulics produces oil pressure for the traction
motors. Each rear wheel has its own motor. The flow divider valve
distributes oil pressure between the rear and the front. Motive power
to the front wheels is transmitted through the reduction gears from
the gearbox driven by a hydraulic motor. Ground speed depends on
the speed range, engine revolutions and the drive pedal position.

Harvesting Computer
The harvesting computer measures the wood and controls the harvester head functions.
It calculates the volume of wood harvested, divided according to tree species
and assortments. All the working data is stored in the computer´s memory and can be
printed out and forwarded wirelessly. The harvesting computer is used to adjust the
harvester head pressures.
Electric sensors monitor the length and thickness of the tree being harvested. Based
on the sensor data, the harvesting computer calculates the volume of wood. The harvesting
computer consists of modules. Wood volume calculation can be monitored on
the display module in the cab. The head module collects data on the harvester head
functions. The modules are connected together with a CAN route.
Control System
The IQAN system adjusts and programs hydraulic harvester functions such as the
crane movement speeds. It has a data connection to the diesel engine, transmission
and harvesting computer. The IQAN functions can be programmed by means
of a graphic display. The colour display contains all the data shown on a conventional
instrument panel. Error messages from the diesel and the base machine are shown on
the display in simple language.
