Ponsse has a long history of
making harvester heads. The
very first were manufactured
in the 1980s and, ever since,
each harvester head model has
been designed with a focus on
efficiency, durability and ease
of maintenance. Each model is
characterized by its simple and
strong structure.
Ponsse harvester heads are
built to meet the demands of the
roughest conditions and thanks to
the wide range, the manufacturer
can offer solutions from rubber-
wheeled harvesters to track-based
machines.
The Ponsse harvester head
range offers 11 modern harvester
head models, which are suitable for
various uses from thinning to final
felling and processing. Their high
feed power and fast economical
sawing result in extreme efficiency.
As each harvester head can be
adjusted according to tree and
base machine properties, working
is easy and the harvester head
has a long service life. Moreover,
Ponsse´s in-house developed and
manufactured Opti information
system guarantees measurement
accuracy in cutting.
“All our harvester heads of
different sizes are also suitable for
the multi-stemming of energy wood
and pulpwood without any optional
equipment,” says Janne Loponen,
Product Manager for Ponsse
Harvester Heads.
“This eliminates additional
costs, servicing and weight. The
frames of our harvester heads
are machined after the welding
assembly. This guarantees the
highest quality wi th excellent
precision.
“Durable hoses, well-designed
hose routing and strong delimbing
knives are important features
of Ponsse harvester heads. In
addition, the automatic Ponsse
CT+ chain tensioner and the grease
lubrication system for the saw
chain are available for all harvester
head models except H10 where saw
unit is Hultdins 300.
“For H7 and H8 models a
stronger HD version is available for
track-based harvester installations
and can also be used in larger
wheel based harvesters. The H8,
H8HD and H10 models can be
equipped with a top saw and find
end sensor for even more efficient
logging.”
H8HD AND H10: modern heads
for the most demanding
conditions

family, the H8 HD, which is a heavy-
duty harvester head for felling
and processing of hardwood and
softwood in tough conditions.
Thanks to the modern and
optimized design of H8 HD, the
weight of the harvester head is
low, making it possible to use it
on the Ponsse Bear, wheel-based
harvester and most track-based
machines. Low weight also enables
lower fuel consumption and easier
handling, especially in processing
operations.
“Strong grip, powerful feeding
and fast sawing are packed in a
robust and reliable package that
can be fitted into various tracked
carriers,” Loponen said.
The H8 HD has a wide feed
roller geometry that supports
even the largest stems with feed
rollers instead of delimbing knives.
This allows a lower pressure to be
applied by the knives, improving
fuel economy and feeding speed as
well as measuring accuracy.
The H8 HD is available with
a top saw for processing curvy
trees with big branches. Processor
delimbing knives are longer than
standard knives for picking logs
more easily from a pile, Loponen
added.

processing head, offers unbeatable
Ponsse quality and productivity
