ROTTNE H8
A SMALL HARVESTER WITH GREAT QUALITIES
H8

CLEANER ENGINE
Rottne H-8 has a powerful new 4-cylinder
tier 3 diesel engine. It easily satisfies emission
requirements for modern industrial engines.
The new engine has been named Power Tech
Plus and it has, among other things, 4-valve
technology, a Common Rail injection system and
a variable turbocharger. This technology and
electronic means of control enables the power
curve and torque to be adapted to the optimum
rpm range for harvesters, which means that the
harvester can be operated at a lower working
engine speed.
Compared with its predecessor, the new engine
also produces a much more rapid response,
less vibrations, a lower noise level and most
importantly lower fuel consumption.
EFFECTIVE THINNING HARVESTER
Fantastic overview and visibility.
Rottne H-8 is an ideal harvester for stand operated
thinning, and with various working route system
options it can handle strip road distances of up to 35
metres without manual intermediate zone felling.
The two-part chassis with an articulated joint in the
centre produces precise tracking, and when combined
with its levelling capabilities, this harvester becomes
extremely flexible and easy to drive when working on
a secondary road out in the stand.
An optional rear vision system with a camera mounted
on the back of the cab gives the operator a better
overview. When reversing, pictures from the camera
are automatically displayed on the D5 display.
RK 50 is a parallel acting loader with a 1.4 metre
extension and tilt function for the turntable.
The loader is thus extremely flexible and versatile
in dense thinnings.

LARGE AND COMFORTABLE CAB
The spacious and comfortable cab with its large windows
affords the operator an excellent view of the entire working
area. The ergonomically designed operator station has wellthought-out
instrument panels to the side and in front of the
operator's seat, which has air suspension and is equipped
with Airvent. The infinitely adjustable armrests feature integrated
lever panels with function keys used for controlling
the head during felling and processing.
The computer screens for the D5 machine control system
and the D5 measuring system, are both colour displays with
a touch screen function. They are positioned low down in
front of the operator so as not to interrupt the field of view.
An efficient air conditioning system with ACC ensures that
the operator always has fresh air and a comfortable cab
temperature.
A lot of equipment is kept in the cab, and there are plenty of
boxes and storage compartments for equipment that needs
to be carried as part of the operator's day-to-day work.

EGS 405
THE HEAD
EGS 405 is a well-tested head of conventional design with two feed
rollers of steel or solid rubber, two pairs of moving delimbing knives
and a saw unit with automatic chain tensioning.
The compact design and low weight make it ideal for use in all
types of thinning stand. The head has a short frame and it is
possible to control the upper and lower delimbing knives and
wheel arms separately.
These factors together with the heads high tractive force provide
excellent conditions for processing bent and difficult to delimb
hardwood. Colour marking and stump spray application equipment
are available as option.
WELL DESIGNED
Rottne H-8 has a narrow and compact chassis with a swing arm
system that gives the machine unique terrain handling qualities.
The four wheel arms have a large swing movement, which means
levelling can equal out both lengthways and sideways inclines, as
well as give good ground clearance in stony and uneven terrain.
The pendulum arm system minimises the amount of space needed
for the harvester and improves weight distribution and stability so
that felling and processing can be performed at full reach even to
the side.
The hydraulic system, which is load-sensing, has a large
pump capacity and provides the loader and head with distinct
and rapid movements. The flexible parallel loader RK 50
has a good reach and a lifting force ideally suited to
the head weight.

ROTTNE-H8
A SMALL HARVESTER WITH
HUGE POTENTIAL
Several evaluation studies have shown
that stand-operating harvesters produce
the most consistent results during
mechanical thinning. Rottne H-8 has all
the qualities required to ensure successful
thinning using secondary roads in the
stand.
The pendulum arm system means that
the machine width is always maintained,
even when the ground is uneven or you
encounter an obstacle. The operator sits
in a cab offering superb all-round visibility,
while hydrostatic operation and precise
tracking make this small yet flexible
harvester even more versatile and easy to
move forwards or backwards with great
precision.
It is easier to select the right tree when
the operator is never more than 6-7 metres
from the trees to be felled and the
risk of damage to standing forest is also
reduced considerably more than if thinning
were to be performed from a strip
road 10-12 metres away.
When the harvester is equipped with a
system for GPS/GIS, the forwarder operator
can access tract maps with working
routes and timber volumes per strip
road to ensure that everything is being
collected. The landowner can also access
detailed information about thinning for his
forest management plan.

ROTTNE D5
The machine control system Rottne D5, which is based on
CAN bus technology, controls and monitors the engine,
transmission, loader, and head. D5 comprises a main computer,
a 7” colour touch screen, and a number of nodes set out
on the machine close to the function to be controlled.
The main computer communicates by means of a CAN bus cable
linked to all the nodes. The operator can adjust settings for the
loader, transmission and engine, monitor pressure, temperatures
and fluid levels and perform troubleshooting using the display
(touch screen) on an adjustable arm slightly forward of the operator.
Alarms are indicated by visual and audible signals and are displayed
in clear text on the display.
ROTTNE D5 MEASURING SYSTEM
A new generation of measuring system with the designation Rottne
D5 is currently replacing the old D4 system. This is based on new
technology and the hardware is the same as in the machine control
system D5.
The software for the bucking system uses the same calculation
algorithms as D4, but in D5 the operating screen looks different, has
more settings options and is generally more user-friendly.

SERVICE ACCESS
Serviceability is an important factor during development work on all Rottne machines.
Downtime can prove expensive for machine owners and good service access can significantly
reduce the time needed for servicing, repairs and cleaning. Rottne H-8 is no exception
in this respect. The entire engine compartment can be accessed easily by
tilting the engine hood back and the oil tanks to the side.
Even the cab can be tilted to the side during servicing work on hoses and blocks underneath
the machine. The distribution box with fuses and relays, and computers, are well positioned
for easy access when the right cab door is opened. A vacuum pump for the hydraulic
system reduces oil spillage when replacing hoses, for example, and an electric pump makes
a change or replenishing of hydraulic oil easier.
